No network until I restart the damn phone - Galaxy S III Q&A, Help & Troubleshooting

Hi
I have a query, I live in a part of the city where my signal reception is pretty poor. So I get a lot of dropped calls and some times msgs don't get delivered to me and calls from other people don't reach me and neither can I call. However the bars in the network zone are always showing a strength of 3 or 4 bars. Initially turning the device into airplane mode and then turning it off used to work at times, but now it doesn't so I don't know if that was a placebo. However now most of the times the issue is resolved by restarting the device. It works 90% of the times I'd say. Sometimes I don't even realise it but I get a bunch of messages when I wake up so I know my phone ws not reachable.
I'm planning to change my network soon, but I was wondering what does restarting the phone actually do and can that be mimicked by doing something else which is a little less time consuming. Also is there a way to know if I'm not reachable to the other person, the bars in the signal strength icon don't seem to be accurate at all.
Anybody?

Are you already on a rom or just stock?
Not sure if this would be any help but maybe a network booster app of some sort would help.

as what the dude above me said, network booster app might help you out on that.
rebooting would force your phone to look for signal the intense way (that's how i see it xD hahaha)
perhaps changing to another network would be your best bet

Thanks for the replies. I'm on stock ics as of now. I was told those network booster apps are just Crappy but it's well worth a shot. Any recommendations?

Fixing Signal Issues (3G/H Switching)

Hi
Does anyone know how to fix this issue? I am in a good area for signal and with previous phones am consistently on H. With my S2 it frequently switches between 3G and H even if it stays in the same spot. It will do it every few minutes.
This is causing havok when I try and tether and my Transformer and laptop keep getting signal interruptions.
Does anyone have a fix? I have Fast Dormancy disabled and I'm aware there may be some other engineer menus that have signal settings in that might work?
Thanks

Interesting.. And I thought it was just my network vodafone
Mine also switches between G/H/H+ all within 5 secs... yeah 5 seconds and it is kinda annoying.
Are you on GIFFGAFF as stated on you profile? or other network? cause I thought if might have do to something with vodafone..
Otherwise may be its something to do with the hardware settings, I too would like to know the answer
I've kept mine to use WCMA all the times...

Yes, I'm on giffgaff.
Glad its not just me. Maybe the antenna is a little too sensitive.
Anyone know the secret code to get to the GSM/UTMS bits?

Now, for me wouldn't 3G and H/H+ both be considered as WCDMA under Mobile Network Settings? G and E would be GSM right?
If that is the case, staying on WCDMA wouldn't fix the problem.

Your phone shouldn't lock onto a H/H+ signal unless it has started to download data. That's how the protocol works.
If your phone is sitting idle it should be on 3G.
You should only get H/H+ when your phone is actively downloading.

OK. So how can I stop it flicking between the H and 3G. For instance when I am trying to stream it will get interrupted, or if I'm wirelessly tethered?

No problems to report in Amsterdam.
I'm biking through the whole city to get to work, no disconnects using TuneIn or Google Music. Provider is Vodafone, HSDPA+ all along the way.
Its Android issue
Think when iPhone, Windows phones have not had this issue, wat else other than Android. I have tried 3 different handsets. 3 different network - 3, O2 and Vodaphone. All has same problem. Android is the only thing common. I have been scouring the internet and posted everwhere possible since Dec 2010 from when I became Android user. There is no solution. Everone seems busy making their own Android versions and apps. Result there is no basic data and voice stability on Android. Have been relying on my decade old treo to receive n make important calls. Wonder where this is going. My heart n soul seems to sway to the iPhone lately. Atleast wat they give works well.
Its Android issue
BTW those config settings are useless too. I have even used the code to get into hidden menu and change config but no use. It's the same issue. From H to 3g and from G to E I gsm.
Sorry for the question, but whats the problem with switching? I have the same thing but is not a problem for me.
Sent from my GT-I9100 using XDA App
Nobody should get worried about that switching, THIS IS NORMAL!
H/H+ is an high speed 3G protocol.
Basically:
1. 3G means DL 384 Kbps tops. The modem is under 3G signal most of the time. Whenever something on your phone starts checking/d-loading it communicates at THE BEGINNING under 3G protocol. Also, long ping time> 210 ms.
2. HSDPA max 14 Mbps/HSDPA+ can go as high as 42 Mbps ( topped only by cell tower). If there's need for large packet data or shorter ping time, IT AUTOMATICALLY SWITCHES TO H/H+(IF AVAIL). Hsdpa consumes more power and it's a communication protocol. When connected under H/H+ error correction bits are transmitted along data stream. It's like switching your home wifi on b/g/n. ...or like the automatic gearbox going to overdrive.
If you see a lot of this switching it means there's a lot of downloading/uploading going on.
I have it switching too between 3g and h on o2 and its making the internet so unstable you cannot do anything at all. This is certain not normal as the switch happens every second and continues to do so until phone is off
Mine is also switching to 3G once connection is idle for about 3 seconds. So far no problem and it uses less power than my SGS1 for browsing since my SGS1 doesn't switch to 3G when idle.
Mine is no problem between this signal switching, check your area or check your country maybe too much communication devices there so that's why it is distorted. Just use the common carrier with plenty of cell sites for a good signal of your phone.
What do i need to dial to fix it to 3g only from 2g?

[Q] Losing signal on my Amaze 4G

Okay, here is my problem: Every once in a while I will completely lose all signal on my phone. It wont pick up 2G, 4G, nothing. Wifi and bluetooth both seem to work though just fine. I've searched and haven't found anyone with the same issues so I'm wondering if it's just my phone or if nobody has commented on it. I first noticed this about two weeks ago, when my phone refused to find service. I was stuck with the little X next to the signal meter. I figured I was just in an area with poor service and didn't think much of it. An hour later, still, no service. This time I went outside where I know I have good 4G service and nothing for 5 minutes. I enabled airplane mode and disabled it, still nothing. Turned the phone off and back on as a last resort. Still nothing. I ended up finishing the day with wifi calling as that still worked. Sometime later my phone began receiving service again so I thought it was a fluke issue.
Then, just yesterday the same thing happened. This was when I rebooted my phone (which bypasses the fastboot feature) and service was restored right away. I called T-mobile and they said there weren't any network issues in my area and they had never heard of this issue before on the Amaze.
So, this is where I'm asking if anyone has heard of this before. I'm running a stock ROM and it hasn't been rooted. Thanks for any comments!
This might help just a touch. I do live in an area with decent service but my couch and bedroom are deadzones for some odd reason. I bought these signal boosters for 2 bucks figuring "what the hell, I'll give it a shot". No more dead zones, and data went from E to G. Not a miracle worker but for a couple bucks it keeps a signal at least.

Wireless Coverage
I have 2 brand new Amaze 4G for a few months now and had no problem with the coverage. I know the coverage is good with full signal bars and have not found any issue with coverage.
Sometimes, different phones have different received signal sensitivity. Also depends on user behavior. If you are always using a handsfree device (cable or BT) and your phone is in a bag, then your coverage is reduced by your action. The best coverage you can ever get is when you have line of sight (unobstructed) to the cell towers.
There are a few issues with your problem:
1-Poor inbuilding coverage
2-Poor coverage in your area
3-Network optimization issue
4-Hardware issue
If you are going from 1 bar to no bar, then most likely you have coverage issue. You lost signal since the level is already very low.
If you are going from full bar to no bar, you might have hardware or network optimization issue. Try your phone is the city or area with known good coverage first. If the behavior persists, then you have phone problem.
I used to manage wireless network for carriers.
same issue
I've had the exact same thing happen to me. Red x, no signal except wifi, in places where signal is not normally an issue. Battery pull doesn't work, return to signal seems arbitrary. Had the same thing happen with my Desire. I have no answers, but you are not alone.
Yup, it happened with my first Amaze. I got it back in January and started playing with it - rooting, custom ROMs, etc. Then later that day, the signal just died on me. I thought I must've screwed something up, so I flashed back to everything stock. No luck. I waited for half a day, then it randomly started working again at night.
You probably noticed tha tI said that happened with my first amaze. That's because after that signal issue, I discovered that my camera stopped working. I returned it to T-Mobile and they sent me another one. This one is working great though.
Well thank you for all the input so far. Id like to say that this isn't my first cell phone and I'm not new to weak or poor signal areas, especially from T-mobile. I was using my phone at work at the time, which has anywhere from no signal to 3 bars depending on where you are. This wasn't one of the cases that I was standing in a dead zone when I checked my phone. I had no signal for several hours, including over 30 minutes of standing outside trying everything I could think of. I have had excellent signal outside in the past, exactly where I was "Hiding". I got the Amaze because I was tired of playing with my old HD2 and having to work around bugs and possibly not receiving calls. So far, I'm not happy that the radio seems to quit responding all together and leaves me without a phone (minus the wifi calling but I'm not always around a hotspot).
I also experienced a dramatic signal loss at home, going from full signal strength to maybe one bar right around the time that I first had issues. I don't know if this is related or if this is a completely different thing.
I am 99% sure this is an error with the phone - probably software related with the radio driver(s) or radio firmware. I guess I will try taking it back to T-mobile and seeing if they could exchange it for a new one. I was just really wanting to avoid that as I finally got my phone setup how I like it. Again, Thank you for the input and let me know if you are having the same problem or if you know of a solution.
I am on my third Amaze and also tried a Galaxy SII X due to the same problem at my home. Even the Samsung did the same thing. In my house and especially in the driveway, the signal varies wildly between -85dbm to as low as -111dbm. The frustrating thing is once it loses the signal, it doesn't seem to reacquire it without a reboot.
I'm with Telus, and they said they will check on it, but I'm not holding my breath. In my immediate area, outside my house, the signal isn't great, but it will usually hang on. I have been to different cities, and all has been well with it. Coming from a rock steady 2G Touch Pro II, I am disappointed as well..
I am new here to this site, but I am having a similar problem with my Amaze. At work I always have a weak 4G signal, but the last few days it has been gone altogether. I have full phone service (4 bars) but no data. The 4G indicates I have signal, but I can't connect to anything on the web. I called HTC and they had me pull my battery and sim card so they could send a "reset signal" to my phone. After my phone came back up I had faster service than ever, but it only lasted a few minutes and went away again. I am thinking this is a phone issue. Oh, the Amaze is my first Android. My only previous smartphone was my Nokia E71x.
I know if I have WiFi calling selected, an x will show up on my signal if i turn WiFi on. I've personally only had slow data in the area I work. I blame it on the fact that it is a busy corporate park with lots of hotels, cuz my signal is fine elsewhere. Try calling tmobile and seeing if they have known tower issues in your area. I know I had that problem with sprint and they sent me a free airave. Maybe tmobile could do something similar if its.a known problem.

It's most likely a network issue. I get the same thing, it will timeout/refresh the network where it will not get a signal for about 30 seconds a few times per day. I blame the network, since the same thing happened to me with my mt4g

Thank you! This fixed it for me. It was happening only today while I had WiFi enabled, it would turn the mobile radio off completely and the box would be grayed out so I was unable to turn it back on. I had my sim updated today to enable wifi calling so after I read your post, I turned the wifi calling off and the mobile radio signal came back immediately. Strange bug.

I was told It's by design. It saved battery life by not constantly searching for a mobile network it won't use (due to wifi calling). It's not like you can hand off the call to the local network. I do notice that if i start walking outside, once my wifi hits a low signal it logs back on the network.

There is actually an option to specify how the WIFI calling works: either all the time or only when cellular signal is gone. Sounds like you have it set to be on all the time. This means that if you have a good WIFI connection, the cellular radio is shut off and all traffic goes through the WIFI calling app. The other option (which I use) only uses wifi calling when there is no cellular signal.
I have lost cellular signal 3 additional times since my last post. Its not just that I'm in a bad spot and I have no signal for 30 seconds. This goes on for 30 minutes or more - up to several hours. I have found that rebooting the phone fixes it as I believe it completely (as much as possible) removes power from the radio and requires it to be completely re-initiated during the reboot. Simply shutting it off doesn't work as the quickboot is enabled and most likely doesn't perform a complete re-initialization of the radio. My only guess at this point is that there is some kind of possible leftover code from development which never was removed from the radio (this happens more times than not). It could be a timeout or simply causing the radio to hang because of 1. excessive heat generation, 2. excessive power drain, 3. buffer overflow, 4. excessive RF transmit power... In any case, one of those issues could trigger an event in the radio to cause it to simply stop responding.
I am in the process of trying to get T-Mobile to get me a new phone as I am outside of the 30-day window. I have also confirmed it with them that this was not a tower issue.
Thanks

Shoot, I see senior members start new threads or pointless threads without searching first, so good job haha.
Ok, back on topic now, if it's only dropping when you go in your room, then I don't think it's anything wrong with the phone. Not sure who your provider is, but u may be able to call them and have them look up your address and tell you what kind of signal u should get outside your house, and what to expect inside your house. I know t-mobile does at least

Next thing, I don't know why a t-mo rep would tell you to root the phone, rooting has no effect on your signal strength or your ability to connect to a network.
And lastly, is the phone a T-Mobile branded amaze owhat carrierr...? and will it not connect at all, period, or can u make calls just not data...?

[Q] Network registration issue?

Hi All,
I am having a strange problem with my S2 since last few months. I am from Mumbai, India and using Airtel network. There is a spot in my apartment which has very poor network reception of Airtel and I face issues whenever my cell is in that spot for a while. It happens that whenever I take my cell in that area, it starts losing signal bars till no bars are highlighted on the status bar at the top. It keeps showing zero bars but does not show "no signal" icon. Then, after keeping my cell in that spot for a while when I bring it in a better connectivity spot, signal bars start increasing and it appears that my cell has better reception again. However, if anyone tries to call me or I try to call anyone, they get "Out of coverage area" message or I get "Network registration failed" message respectively. I am having this problem since the day I started using Airtel and have tried a lot of remedies but only thing that works is rebooting my cell. I have tried using OpenSignal app to reset my connection whenever my cell comes back from the spot but even that fails to revive it and ultimately I have to reboot.
Has anyone faced such an issue and any ideas about a fix? Does it look like an issue with my cell or could it be an issue with my network provider? I would prefer not to root my S2 since I have 3 years warranty on it but if you think that it's the only way out of this, please let me know your opinion.
Thanks.
Sounds like a carrier issue to me. You pretty much said exactly that yourself when you said 'There is a spot in my apartment which has very poor network reception of Airtel and I face issues whenever my cell is in that spot for a while'.
That's normal in many buildings. Particularly if the network coverage in your area is borderline or poor. I have a similar issue in my house, in a few rooms I get no bars & sometimes coverage drops out completely, whereas in my loungeroom/dining/kitchen at the back of the house I get good coverage (for me, anyways).
You could try different modems, which might improve things. You don't have to be rooted to flash these, you can flash them using Odin. Tho it is easier to flash them with CWM if you're rooted.
I use to had the same issue with my 3 carrier at my desk in the office, and still on 2g services. I but since last month they already improved to hsdpa network added more bts and now my blank spot became H.
Yes you may try to change other service providers
Sent from my GT-I9100 using xda premium
Thanks for your suggestions guys. Yes, it might be only related to the carrier. But, I think that if signal goes down to zero and then when my cell is back in better coverage zone, shouldn't the modem take care of network registration by itself? My problem is that it doesn't. I have to reboot my cell every time after I come to know that my cell is showing signal bars but is not actually registered on the network. If I reboot my cell, everything becomes normal and so if it was just an issue with the carrier, shouldn't it continue like that even after reboot? If I think about it logically, I think following should help me out:
1. Try out a different cell for a few days and see if I face this issue or not.
2. If answer to 1 is no, then try out different modems on my S2 and see if that helps.
Actually, I just wanted to check if anyone else has faced this issue and figured out that something is not right with S2 drivers or something? That would help me with quick resolution of my problem.
Sent from my GT-I9100 using XDA
Yep, your logic is sound ;-)
One thing tho. With regard to trying your sim out in another phone, you have to keep in mind the radio hardware is obviously different in different phones. And what that means is (and this is something I've observed on XDA), chances are you'll find the sim works perfectly in the other phone & you have no issues at all. This might be due to the actual equipment your carrier is using in the cell tower(s) you're close to, also the frequencies that gear is using might also be playing a part in your problems.
So definitely try it out in another phone & see what happens, but you could do worse than try out a bunch of modems in the S2 & see if that improves things.

Those are carrier issues, and maybe even the material of the constructions, in my house there are rooms where there's almost no signal at all, and in the living room it's ok, you should try to see in which tower you are connected maybe thats the problem
I have also had these problems on various networks here in Australia. If you don't need the data network, you could try using 2G only option. But that's not really a fix, is it? I suggest you try a pre-paid SIM from another network provider, to test them out first, before re-contracting.
Good luck. :fingers-crossed:

Yes, I was also thinking about it. It could be the combo of cell tower and S2 that are not liking each other that well.. And, if that's the case, I really hope that the issue can be resolved by switching modem drivers. I will have to do some what-ifings to nail this down now.
I like the other suggestion by HotrodHarry on trying out 2G only option - not the best way out but will help me in zeroing down on the cause.

How to increase consistency/strength of the phone signal

My phone - I have ICS - S-OFF Amaze with Energy ROM and I had tried to apply blas0id tweaks.
The problem - In certain areas I don't have phone signal for a few minutes, then suddenly it will show 4 bars for a few minutes. In general the signal seems fickle.
Before ICS upgrade, when I had GB, I always had 4 bars in the same places. I *think* I had good signal with ICS before I did blat0id tweaks, but I am not certain of that. (ICS and the tweaks were within a few days)
My wife's Iphone still has excellent signal in those places. Tmobile Mytouch also has excellent signal in the same places. So something has changed on my amaze and not the cell towers.
What I have done so far -
1. went back to stock ICS by flashing the img file. That did not improve the signal. So then got back to energy
2. Tried another ROM - speedrom. No improvement in signal
3. Tried few apps like fresh network. They did not help
Please help me
What can/should I do? I love my amaze, but if I dont get consistent signal, I will have to replace it
Are there any tweaks that I can try?
How about the custom kernels that have been made for ICS recently, would those help?
Is there a way to increase the power to look for and catch on better signal? I can trade battery life for better signal
Thanks
I have same issue but with WiFi only. I never had GB I hope there is a work around

Found a workaround
This was dumb luck, but when I was trying to play around the app opensignal, it wanted me to set 2G for some of its functionality, since that functionality does not work over 3g. So I went to setup and set Network mode to "GSM Only" from "GSM/WCDMA Auto"
And walla! right after that my signal jumped from 1 bar to 4 bars and has stayed there. I went back to WCDMA and signal dropped, so now I change the network mode only when I need 4G. Its a pain, but at least, the signal is good when I need it.
So with that information, can someone help how I can tweak something to get my 4G and also good signal?
Thanks
try updating the radio if you have done so, even though you are going to have to go through the process of locking the device again and unlocking the bootloader again, that would be an idea to try, we still dont know what changes R2 radio update has done but its deff worth a shot

I checked the version of my software and I think I already have R2
Build number
2.14.531.3_R2 CL373265 release-keys
So not sure if that would change anything
I have always had this problem as well sometimes I have 4 bars of signal then it drops to the X as in no signal,can't make calls or sends texts until it picks up again, happens totally random don't think it has to do anything with tmobile coverage since I live in the center of Miami. Also most of the time I have 2 bars of signal in most places, I believe it's faulty hardware

Krazex .. did you try to set your network mode and see if that helps your signal stick around longer and get better signal? That is working well for me.
I've tried setting my network to GSA and my data speed dropped to 2G.

yup, that's what this setting is supposed to do, but it increased the quality of my phone signal, that is what I am trying to make better/consistent. Because even after all the bells and whistles, calling someone/receiving the calls is the primary purpose of the phone for me and if that doesn't work, the phone doesn't work for me
GSM = 2G
WCDMA = 3G/4G
Get a new SIM card.
My amaze won't get 4g in my house whatsoever, only switches to 2g when it feels like it.

A new sim card is a good idea.. so is removing the back cover and cleaning off the contacts with a q-tip and some rubbing alcohol. Taking something and SLIGHTLY bending out each of the gold contacts so they make better contact with the case, making sure there is no debris.
Another thing to look into- there is a TON of hacks for cellphone signal that can be done in build.prop.. playing with those settings is probably a good idea.
The last idea- the signal is actually NOT different. The number of bars it shows you is now just more ACCURATE. You still lose signal in ONLY the exact places you would have before.. but now when your phone would show you as having 1 or 2 bars(on gingerbread) right before you lose all signal, on ICS it shows you as having NO bars because you truly have almost lost the signal. It is VERY accurate, now that I am in an area with bad signal.. I have actually flashed gingerbread again and things did NOT get better, there was just fewer bars that weren't as accurate. But I lost signal in the same spots, and would lost 4g in the same exact spots..

Guys, OP here. This question/workaround is not about getting 4G. I am getting 4G just fine. Its about the phone signal (the bars). My amaze does not get good phone signal in some areas and when I set the network mode to GSM only (2G), phone signal strength and stability increases. and now I want to figure out how I can keep the setting to 4G and get a good phone signal

Hi SBD, thanks for coming in. I will look into build.prop (ro.ril properties I think) I will also clean any dust inside the phone, may be that will help. The sim card was new when I got my amaze .. but no harm in trying. So I will ask for a new sim card too.
However, in my case, I have a different experience. This is what I did in a weak signal spot.
Have 4G on. I get 0 signal. Can't make a call
go to 2G at the same spot, I get 2-3 bars. I can make a call
I used opensignal app to check signal strength in both cases. with 4G it showed 0. With 2G it showed 42%
Another test. On my route to drop kids off for their day camp, I was on a call (with 4G on) and dropped the call twice (bad reception areas) while going. I switched it to 2G and while coming back did not drop the call.
Before I found this workaround .. people called me and complained that it directly went to voicemail and I never got the call. (no signal). Since I found the workaround, I haven't heard that from anyone.
So I am convinced that there are some real issues in catching the signal with 4G on that get resolved in "2G only" mode. (may be it has to do with the kind of cell towers we have in our area and nothing to do with the phone)
will update if I find more

Yea, it should be lines that have ro.ril that youd eant to change.. and fortunately one of those that you can add(it isn't included by default) will do exactly what you need, default to 2g signal when 4g is too weak. I actually need the same thing, in Jacksonville we have great signal.. except in this new place I moved into. It drains my battery by trying to stay with 4g.. but I don't have time before work to find it.
Look for a tthread by "master&slave" titled something like "super build.prop tweaks" in the vibrant forums, I THINK they had that line.. otherwise google around for something like "build.prop signal tweak" as if it isisn't in that thread, there's a really good one on some other forum.
Also, I remember there being some app that requires root that allows you to toggle between GSM preferred and 2g only.. it changes it at system level, and I don't think it was on the play store, I think it was on Xda.
But yea, I understand your dilemma, and until we get an alternative radio to flash(which I don't forsee), that is the kind of workarounds you need. If you find a reasonable solution make sure to post as it will help me too!

I have had this problem ever since I got my phone in October (right after launch). Updating to ICS didn't help. i've been planning to root and try another ROM, but so far have been skittish as this is my only phone. hasoon, you say it's the SIM card? I am trying the switch to GSM only to see if it makes a difference. My problem is at home - I have terrible service and I live on a mountain with cell phone towers everywhere. My daughter's AT&T and my old AT&T Nokia E71x had excellent service there. I'll let you know if this helps. Maybe a trip to my local t-Mobile store is in order.
It's not the sim card. I noticed on google a lot of people have this problem with htc phones. It's just a bad radio.

Signal drop out issues - Please help

Good day all!
I've been experiencing some issues since I got my C6806 3 weeks ago. I live in Toronto and my provider is Rogers. The phone itself is unlocked and is just running the stock software which is 4.2.2, build # 14.1.B.2.257
Ever since I got the phone I've had a periodic issue where the phone signal strength will just completely die out to 0 bars, then it'll come back to full bars about 30 seconds later. It happens whether I'm home or out on the road. It happens if I'm using LTE bands or 3G or HSPA. It also happens whether I've got wifi on or off.
Any troubleshooting steps you could suggest?
Thanks in advance!

has it always happened?
Have you got stamina mode on? Turn stamina mode off and see if it stops..

It seems to happen on a frequent basis. At least a couple of times a day when I happen to be paying attention to my phone.
I've never actually used stamina mode, and it's always been off.
How's LTE and HSPA where you are? If the signal is poor it'll switch over to the next thing on ladder. If you have a poor LTE signal it'll jump down to HSPA, and if you have a poor signal on that one it'll jump down to EDGE. It's the same dance if you walk into an area where there is good LTE coverage. It jump up from EDGE or HSPA to LTE, and iin all cases when it switches, you'll notice a couple of seconds where it connects to the new frequency (by having zero signal). That's why I disable LTE when I know I'm going to be in an area with poor LTE signal for a long period of time.
Not saying that this is your problem, but try only using EDGE for a couple of hours and see if it happens again.

LTE and HSPA coverage by Rogers in Toronto is great overall. I don't really use the LTE APN because it seems to suck up battery life immensely. I just keep it in the normal APN that seems to switch randomly between HSPA and 3G. The issue can occur if I'm just sitting still in a spot. I'm using it, and all of a sudden the signal just cuts out for about 30 seconds and comes back. Both before and after the incident I am usually at full bars.
I'm unsure of what EDGE is. The only things I control are the APNs I obtained from Rogers - one is just the standard one that gives me 3G and HSPA, and the other is LTE.
Dunno what else I can really do. I doubt it's my provider so it's gotta be the phone. Any other real troubleshooting steps to try, or should I just get this to Sony?
:good:

EDGE is 2G. so turn off LTE and HSPA+ and see if it does it.
I don't have the LTE equipped phone so I'm not sure if these hardware functions will switch on and off randomly.
It sounds like your hardware is switching between 4g and 3g. problem is that both wont work simultaneously, so you would get this drop off. solution is that build prop edit i gave you.
But then you'd have 4g on all the time. so if you don't want that then turn it off manually.
Try these.
Edit your build.prop file.
(do you know how to do this??)
and insert these.
___________
ro.ril.hsxpa=3
ro.ril.gprsclass=12
ro.ril.hep=1
ro.ril.enable.dtm=1
ro.ril.hsdpa.category=20
ro.ril.hsupa.category=7
ro.ril.enable.a53=1
ro.ril.enable.3g.prefix=1
______________
that will stop hardware switching between 2g/3g/4g
as well as make it faster.
Settings->More...->Mobile Networks->Network Mode->GSM Only
You'll still have mobile data, but it will be SLOW. I think the top speed is around 400KB/sec, but you'll only use this to check if your signal is more stable without 3G/4G.
Tip: If you want to save battery and you aren't the type that uses a lot of mobile data, use EDGE (the thing i'm currently writing about). 4G uses a lot of juice.

Thanks. Just made the change and will keep an eye on it over the next day or two.
Just gotta say holy crap this Edge thing is SO slow. Even just loading icons on Google Plus or Youtube searches takes forever. A mobile speed test is showing about 133 kbps...
Damn... gotta come up with a better solution that doesn't require having slow as shyte data access
I'm trying WCDMA only to see how this might work. At least the speeds are more tolerable there.

Yeah, but keep using it for now. You're only checking if the signal drops while your on it, so I'm not saying that you should keep using it. It's only for a couple of hours. You can do it!

EDIT. Nevermind the part below. I just kept trying more SMS apps until I settled upon GO SMS and it seems to finally be able to load photos. Damned weird the default one wouldn't do it
On another note, can anyone explain why the built in Messaging app has issues both sending and recieving photos? Plus there're a few instances where it says I've got a message, but I've viewed them all. I've even tried downloading a few other messaging apps from the Play store, and they can't seem to view or send photos either. Damned weird if you ask me.

I'm not using the stock messaging app. I'm using Hangouts as my main SMS app, but I didn't have any issues with it when I used it. The Android 4.3 update is released now, so you can update to it through PC Companion? Note that this will remove root and stuff like if you're rooted. If not, go ahead.

Sorry to bump an old thread, but I just want to say that I'm having the exact same issue. I thought it might have occurred after I installed a custom room but I'm now back on stock and still experiencing 4 bars immediately dropping to no service and then going back to 3 or 4 bars before slowly dropping back to zero. I figured it could be LTE, so I experimented with all settings under mobile networks to no avail. I try the same Sim in my note 2 in the same location and I have no issues. I believe this is an issue with the antenna or a general hardware fault. My phone is the c6806, originally on Bell but being used on Telus. I have already contacted Sony but they are giving me the runaround
Anyone know how the warranty is handled in Canada? Anyone else have this problem?
Signal issues
Sorry I'm restarting this thread one more time.. But anyone figure out a fix? I'm having the same problem on a brand new phone... I had the same phone before I lost it. Got it again but these signal dropping issues now . Never had these on my previous cc6806
