Please be clear , what does the launcher do with your signal reception ?

H or H+ is your data network displaying that you are using HSPA technology for internet on your phone.
Don't know about the signal strength...

When u have more than 2 bars , it's pretty sure that your voice quality is good for the peer .

You don't need to worry about the icon my friend .
There were different bandwidths even in 3g networks. When u see H+ icon , it was sure that u are getting better speed over Normal 3g network("H" in your case) .

i put the launcher because i have no idea what the issue is/was. all i know is that i get good internet {lte} full bars
and then in the same location when i receive or make a call it drops to one or two bars and the call comes out barely audible,
especially when im in my vehicle and i start to drive

So what I understood is , signal drops to minimum when you got a call and comes to normal when you disconnect the call .
If I am right , just do one thing ..
Take a logcat before making a call and after attempting the call save it and send me or baDeamon in PM .
Sent from my KIW-L22 using Tapatalk

No need for a logcat .
the issue is that he had a 4g LTE and while getting a call network will switch to 3g or 2g and normally it will drop cause each basband have different strength !..
its normal and If u have bad reception means the 2g or 3g network is not good that area !..

loosing the strength of network always depend on network strength only . if he can got a LTE Then he have no issue with software

This is true . but I thought to confirm this by seeing his logs . coz we can't judge something directly without proper investigation

Correct , I believe he need to read about using logcat first ! am assuming he have no idea about that already !.

[Q] No signal when I actually have signal?!

Right sounds abit strange but basically at times I'll have no bars at all, but will still be able to make a call.
And other times it will show 3 bars but I won't be connected to the network.
The reception bars seem to have no relevance on whether I'm getting any network signal.
I'm using leomars rom, is it possibly a software issue.
Does anyone have anything similar?
I'd just like for the reception bars to be accurate, i.e if I have no reception then show no bars, and if I do then show bars
Thanks
edit I've attached a picture showing what I mean, it shows no bars but as you can see I've got a data connection so I must have signal.
hmm, i may have something similar...
when you say no bars, does that mean that they are greyed out as opposed to white bars... or no bars at all?

Sorry my fault, I didn't explain myself correctly.
Yes I mean greyed out, e.g no white bars. In the picture on my first post I've got no white bars so apparently no reception but I've got a 3g connection and can make calls.
And here is a picture showing that I have a few white bars (reception)
Yet I don't have any reception at all. No 3g, and can't make calls
It's so annoying, I've never had anything like this on any phone I've owned before.
When you have no signal at all, you'll get the circle icon thingy instead of bars. Bars all greyed out mean that you just about have a signal (an extremely weak one!) Go to Settings > About phone > Status and have a look at the signal strength details there

Ah ok so that I can deal with.
But what about when it shows a few white bars but then says I'm not connected to the network, so no data connection and unable to calls?
Signal shows -113 dBm 0asu (not sure if that's good or bad)

Could it be a problem with your carrier? Congestion at your local mast could easily cause this.

That's bad! Good signal is a small -dBm figure (so for example -99.dBm would be much better) and high asu.

Thanks for the explanation regarding how the signal figures work.
Going back to what you mention about having white bars and not being able to make calls being congestion. Is there no possibility that it could be a software issue and I actually have no signal but it still shows bars.
Or is it a case where if it shows bars I definitely have signal but likely to be congestion.
Sorry for all the questions
Not sure to be honest. What I have first hand experience of is that when I was with Vodafone, there were big congestion issues in some parts of London and although the phone was getting a full signal, it was unusable (data wouldn't connect and calls would drop) the only solution to at least being able to make and receive calls was to manually switch the phone to 2g only and forget about 3g during the "busy" hours...
Edit: their forum was also full of people complaining about the same problem in other parts of the UK too...

I've got another question regarding the modems, in another thread someone mentioned that if you are having signal issues it's likely down to the incorrect modem being used.
Now generally all I do is pick a custom rom, flash it and then use the phone as normal.
But should I be picking a rom and using a specific modem version?
Thanks again

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

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.

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

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.

[Q] Toggling between 3G network to Edge

You've got to activate 3G on Reliance first...
Some providers do not preactivae 3G on the sims...
FYI, on Aircel u've got to send a text START 3G to 121 to start using 3G..
Check with your provider whether they've got some provisions like this...
Just check whether there is any E icon on the network icon or is it showing 3G/H+???
The latter shows that 3G is activated...
Hope this helps... :good:

3G problem on Moto E
I'm using the Motorola Moto E - Global GSM - Unlocked - 4GB (Black) sold on Amazon.
I relative of mine coming in from UK brought it for me.
I have been using it for 2 days in Mumbai and my carrier is Vodafone.
The problem is that i am unable to connect to 3g on my handset no matter what I do. I have accessed the Supermenu and tried using the WCDMA only option in which i was unable to connect to any network at all and the GSM option only Gives me EDGE as my network type. I know it is a Handset issue and not a carrier issue as i tried my SIM card in an Samsung Galaxy S4 and was able to use H+ network.
I am new on this forum so if you guys could help me i'd be really grateful.

Bad reception

Hi all! First post in the Alpha section... Got my Alpha the other day. And i love all about it. But there is one thing thats gets me wondering. It's the reception. All my previous phones got good reception at home.. i get 1-2 bars. So my question is. Does anybody experience this issue? I have experienced SMS delays and chipped calls.

Look at actual signal strength in dBm. Bars are arbitrary and vary from phone to phone.

It could just be a faulty device... I'll try replacing my sim first. If that's the issue.
If that's not working. I'll have it replaced.
Edit: Had my sim replaced. Still experiencing bad reception. It goes as low as -105dbm... where my z2 had around -70 (same network, same location)... that's bad. Any ideas what I can do to solve this?
Yeah keep me updated - my Alpha also seems to have noticeably weaker reception than my iPhone on 4G (800mhz band).
Hoping its a modem firmware/software power output thing and not a hardware thing.
Same here, looks like the reception is 1-2 bars worse than other phones.
But I have no experience of delayed SMS or failed calls and the speeds on internet is very good.

Signal problems
Hi, I'm on my second Alpha and first sim, I have an alternative sim yet to try but have chated on Twitter with another user who found no improvement with a new sim and changed phones completely. I'm with three. My signal goes completely when I'm sitting with other three users whose phones work fine. I think it's a phone fault and am considering sending it back now.
Hi guys,

As you, I have a poor signal strength. But when calling someone then the signal bar jump to full force instantly!
Could it be a link with BIG little technology?

Well, for those who have the same problem, I deactivated the 4G. Then the signal strength is better. I made the test: 2 bars with 4G enabled in network settings, full signal when 3G only.
As a possible future Alpha owner, question.
Are you on a USA Network with the Qualcomm Alpha ?
Or in Europe on Exynos Octacore ?

The alpha is my second LTE able phone. Both showed a completely different signal bar reading when using LTE (and checking in lecture, how Signal strength is meassured for GPRS/EDGE/UMTS/LTE it shows, that LTE uses a completely revised scheme to calculate the signal strength)
I haven't made any speed measurements yet, but my feeling is:
(4G) With LTE, even without any highlighted bar i can use internet, webpages load fast, other lookups work.
(3G,3.5G) With H/H+ , and at least 1 bar highlighted, internet works
(2.5G) Edge and at least 1 to two bars, internet is available... three bars are better for it to be worthwhile
(2G) G only - forget it. I'll need 4 bars to surf the web, and i must wait. Chat works if i'm lucky and got at least 1-2 bars.
Apart from that: the signal bars in 2G and 3G show the strength of the signal - but aren't any measure of the quality of the signal. They show anything that sends on the frequency/timeslot of the 2G/3G signal you're receiving. If you've got heavy interferences, you'll get full bars but it all is static.
(Like - in a disco, you've got loud music, and people speaking very loudly to you - that would be full bars, but not the best place to speak to each other....)
I don't understand exactly what the value used by 4G exactly means, but it sounds like it only represents the LTE cell you do want to receive - so it should be more accurate and cutting out the noise somehow
I think you're right ! This is my feeling too. In 4G calls are always perfect for me even with one bar.
In settings we can also have a more accurate highlight on to the signal strength in Db.
Guys this alpha is full of mysteriousness !
I think samsung did it ON purpose.. ! Save battery??
I have weaker signal too.. on iphone 5 is full and i had on my former Honor 6 full as hell..
But I dont konw IF samsung wants to save power by this .. I think it has no much influence as iphone 5 nor Honor 6 had full signal and battery never got down fast.. when I had Honor 6 100% at night it was 98 % in morning..
Another thing with aplha ,when i leave phone in sleep half hour or longer , th emobile network stops and wont come up...
I have to restart phone or turn airplane on ad off.. then H+ or 4G appears..
I have the issue with mobile data too, it seems to also do it when it has been on WiFi for a while and you change to mobile data.
no service
Hey guys,
I have a very bad reception with my Samsung Galaxy Alpha when i'm in the subway in Paris. To be honnest I have no service, no sms, no calls, and for sure no internet...
I can see people using their smartphones inside the subway without problems.
I had an iPhone 4 during 3 years, and didn't have any problem with it when I was in the subway.
I'm using the same phone carrier "Bouygues Telecom"
So what's wrong with this Galaxy Alpha ?

it disables data carrier APN and it won't turn it auto i went it that settings and had to tap that circle manually to get green .. think it is bug .. need sorting out updating software..

looks lik eit might be a software problem .. we need to contact samsung bout it or complain on their site.. but guys all of us we must complain not just one person cos they wont sort it out..
Hey people,
I'm also having connection issues:
When I boot the phone it's working is at should: Switching between 4G/3G/EDGE etc. After a while the connection sort of times out. I can only make emergency calls. It works flawlessly for up to a day, or it can only work for like 5 minutes.
Rebooting the device fixes this temporarily. My service provider (Hi in NL) has already sent me a new simcard which doesn't help. They are now saying I should send it over for repair.
Btw: When i leave it in CDMA only, the problem takes much longer to arise (like a couple of days).
I can see that people who have posted in this thread are having the same issues. I'm wondering if this is firmware or hardware related, as I want avoid sending over my phone. If it IS a firmware bug, sending it over for repair obviously isn't going to fix this.
I have sent an e-mail to Samsung BeNeLux. Like Simona Simmy says, we should all write to Samsung

[SOLVED] Lazy to change mode between LTE/UMTS/GSM?

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?
Vodafone Netherlands in Utrecht city.

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.
