I've been hiving this strange issue for a couple of months now.
Hi,
I own an Optimus one Currently running on Froyo Final + franco v19 set at 729/480, smartass. (None of this matters now) Anyway...
Whenever I'm home, the signal is in full strength. However, when I travel, or am at a different destination, there is a constant signal loss.
Signal bar will be at 100% and then suddenly it'll drop to emergency mode and then start hunting for signal. This happens very frequently and drains my battery.
At first I thought this was a rom issue and so I reinstalled everything from scratch (no titanium restores) only to find out that the problem cropped up again.
I switched back to my stock froyo rom which I'd backed up some 4 months ago and the problem didn't seem to go away!
So the only 2 suspects now left are the phone itself, and the sim card.
What am I supposed to do now? Has anyone else experienced such a problem?

Sounds like the phone fails to switch between BTSes properly depending on signal strength, not to mention the failed signal display. RMA it. (Either way, we would not fix your faulty SIM either). Talk to the guys who sold you the phone.

I suspected that too. But the thing is, it was all ok a couple of months before. So its really hard to tell whether its the sim fault or the phone fault. I think I'll talk to the vodafone people first and see if they're able to assist. If not, then rma it is
I would like to know if it was resolved. My wife has the LG P500 model and it drops signal when not at home. LG some how is ignoring our complaints, I've gone for a new sim, but no luck. I'm on the official stock 2.3.3
Edit:
Updated from v20b to v20c, hoping it fixes the issue.

For me it was because I'd set the network mode to GSM/wcdma auto. The moment I set it to Gsm only or wcdma only, the problem disappeared

Alternatively you can go to dialer and press on *#*#4636#*#* and go to phone infomation and scroll down and click on gsm auto prl. Default i think is wcdma preferred which is 3G only while GSM Auto uses 2G when 3G is unavailable

I already have GSM only, tried GSP auto prl which changes the signal icon into roaming mode, so switched back to GSM only.

Ever since Verizon network went down a few days ago I can't get a solid connection whenever I download anything. Browser seems to load fine. I try downloading several apps from the market but cannot complete the download due to lost connectioime. It will just stop at any time during The download. Same with files. I dont think is the rom. I'm on cm7 pre-release. Flash back to Tesla but still have the issue. Is anyone else have this issue?
Are you close to a 4G area? Try locking your radio to 3G and see if it improves.

You go into the phone dialer and input *#*#4636#*#*, choose phone information. LTE mode for only 4G, CDMA auto (PRL) for only 3G. You can change it back to normal by using CDMA + LTE/EvDo auto.
I've been having the same exact problem.

Just installed the latest radio and is still having the same issue. I hope is the network then since you're having the same problem too.
I have das bamf remix 1.5 on my phone and I've been having very slow downloads lately when it says I have a full signal.... Tried both modes as mentioned above and problem persists. Can't even load a whole you tube vid. WTF
New radio problems
I had similair issues, and I went back to stock 605.6 radio and a simple debloat rom and it fixed my issues, I am also set to CDMA(PRL) as I'm in a 3G only area
on the new radio my 3G connection was unstable and my GPS wouldn't lock
all of this only occurred after the verizon network went down and came back up.
before that I was having my problem with the new radio. I'm waiting on 605.6 until Verizon officially updates the radio, because I think they changed something that is currently only working with the old radio, the only one they have to support at this time, just my conjecture of course, but I've tried it a few times going between an old radio/old rom and new radio/new rom and it's consistant
Having the same issues. Tried all the radios, but downloading from the market place still goes at a snails place. Like everyone else this started after the lte network went down and came back up.

Alright, I just got off the phone with them and they fixed my problem in less then 5 minutes. The problem was caused when the network went down, and when it came back up, some of the thunderbolts would not connect correctly causing the connection issues. When I called customer service the woman brought a tech guy on the phone and he had me take the battery out of the phone WHILE IT WAS POWERED UP and then take the SIM card out and he did some kind of "network reset" to my SIM card and now all the issues are gone. Worth giving them a call and seeing if this fixes your problem. IMO VZW has the best customer service hands down, they are always so helpful and will make conversation with you during the luls while on the phone (IE when your phone is booting up).

I have bought a sim free galaxy s2 5 days back . I am in japan.
From day one I have been facing strange problem. If my 3g disconnects for some
Reason such as going into elevator or traveling in underground,
It doesn't come back. I have to reset my use data package network settings or
Turn on the flight mode and turn it of f again to get connection back.
My apn settings are as per my carrier has suggested.
Because of this issue the phone become almost useless while traveling
Or while going up and down in my office building.
I haven't rooted it yet. Is this firmware problem or hardware.
Please help

Some people including myself are having connection issues when gsm/wcdma auto mode is selected...phone is stable when gsm only is selected..after comparing with 2 other phones,i can confirm this behaviour dosent happen on their phone..and i have to sadly say something is wrong with my phone..why dont you do a little experiment..try selecting gsm only mode and see if your connection is stable..maybe you are having a defective phone like some of us here...untill today i cant figure out if its a hardware fault or some weird software glitch.

Many people including me are having this exact same problem. I am suspecting the modem software, and hoping it will be fixed soon. But please note I also held hope for almost a year that GPS glitches in the first galaxy were fixable with software, and now we all now it wasn't.
I'm having the EXACT same problem! Out of nowhere my 3G connection is 'lost?' and I only see an upward green arrow.. i have to reboot to get this right.. but after a short while.. same problem again!
I live in The Netherlands... I wonder what the problem could be, but even better! THE SOLUTION!!

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.
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 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

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

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 will try to figure out what these different ril properties control and which one to modify .. will report after my experimentation. I haven't found a good comprehensive explanation of all those properties yet.
Glad I'm not the only one...

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.

We know. If you wanna help read my post number 16 or try some of the links he posted in 17.. we just need a decent workaround.
I'm experiencing an odd issue on the SD RedMi Note 4 of my wife (ROM: v8.5.8.0 NCFMIED): where LTE signal is weak and other mobiles switch to GSM (2G) and are still reachable, the RedMi of my wife is still trying to get LTE signal, ending up offline for _long_ times.
I tried to switch preferred mode to "LTE/UMTS auto (PRL)" (mido default choice when "prefer LTE" is selected is "LTE/TD-SCDMA/UMTS", which appears to include the Chinese 3G standard too) like my OnePlus 3, which never looses network, but it didn't help: the only way to have it reliably reachable is switching to "GSM only".
I didn't find anything relevant neither by searching nor by browsing the first 30 pages of this subforum: is there anything we can do to improve this? Thanks!
go to about phone. tap multiple times on total memory, a window will open up. open phone information 1,2. choose type of network you want from multiple options

That indeed solves the issue as I wrote, but I don't think that my wife would be happy if I tell her she has to check the signal all the time and, eventually, _try_ to manually switch to "GSM only", and go back when the signal strength improves... that should be modem job!
Update: the affected SIM was in slot 2; moving the SIM to the first slot seems to improve the mode switch. Still the sensitivity doesn't seem exceptional, or perhaps there is some other issue (1), but at least it seems to correctly switch from 4G to 3G and even 2G where the signal is weak.
Testing in "LTE/UMTS auto (PRL)" mode now (I don't need TD-SCDMA here, I assume there is less overhead with less modes); wondering whether is a modem (read: Qualcomm) issue or a MIUI bug.
(1) sometimes the device still looses the network where my OP3 seems connected with very weak signal (-105 dBm) and LTE Discover reports "Potential eCSFB issue detected" (which sounds odd since eCFSB is a CDMA thing, and there aren't any CDMA network here in Italy AFAIK: could it be the way LTE Discover tells that the phone is unable to handshake an existing network?), until it reconnects. Moreover, it seems that RN4 tends to prefer 3G over 2G even when mobile data is off, which is not a good strategy IMO.
Edit: LTE Discover reports "Potential eCSFB issue detected" also on OP3, which works perfectly: it seems its shown when the terminal was unable to successfully register on a network and stays idle until the next connection attempt
I have sort of similar and opposite problems in the USA.
Mine switches from LTE to whatever H+ is and then never switches back on its own. I'm blaming Xiaomi over Qualcomm.

I have the same problem. I have a weak signal reception in my house. Is there a app that can put a phone to 2g when I am on wifi ?

I tried it, it worked if I used the root option and manually hit the refresh button. I read that the auto refresh only works if the signal is one bar or whatever or less.
My signal is strong when it's on H+, so it would never get low enough to make it auto refresh.
What I need is something that would switch my preferred network to Prefer 3G and back to Prefer LTE whenever I'm on H+ for a while, because that gets me back on LTE every time provided that there's LTE in that area.
My Redmi Note 4x international should be capable to connect to the 1800mhz band, which is available in my neighborhood. Sadly I haven't had 4g or LTE since I've gotten this phone (4 weeks) any ideas why it won't connect?

Thank you: started testing. It seems that, despite the better signal, even after refreshing the device still ignores 2G and tries to connect in LTE or H+ mode. I'll see in the next days.

Yep, that's very same issue I'm experiencing. I was feeling alone: in the MI forums I couldn't find no one complaining about that.
Did you notice that when the device connects to a Wi-Fi network the cellular signal indicator suddenly rises (it appears to indicate Wi-Fi signal strength) and appears "4G" next to operator's name, even if cellular data is off?
Too bad, if RN4 didn't have such a bugged radio it was a real bang for the buck.

[Shot in the dark] Did you check your APN settings?
Yes I did, all as it should be

Try to get some more info from the "LTE Discovery" app: is the device registered on the 4G network but internet access is absent or the device doesn't even register on the 4G network? Does the device detect the 4G signals?
In this thread we are discussing about the opposite problem: our devices don't switch to 2G when the signal is weak...

Unfortunately it didn't help: it doesn't seem to improve overall operation. It even asks to refresh the Wi-Fi connection when there is no cellular signal...
There is really something ill in this modem. Sometimes the signal indicator shows Wi-Fi signal strength instead of cellular. I hope some future release will fix at least some of these issues.

Sorry to hear that. Try to report to the developer, so he can solve the issue.

Thank you. I think it's not necessary: since yesterday I'm running MIUI v9.0.3.0 and things improved considerably. I'm quite sure the issue was MIUI 8 which had a complete modem mess, not the app, that was doing its honest work just as it was possible.
