[Q] randomly lossing signal any fix or idea ?

Just get one s and everithing is working fine except phone losing signal I mean am in same 4g area, but phone shows no bars, big X sign and that's it.
Restart phone or airplane mode on off is restarting connection.

Sim card is changed for small one in T-Mobile store.
What's interesting bars going to 0 but 4g is still working, then big X shows and all gone
Access point setup to t-mobile

Same thing happens to me...

Same here sometimes, in Europa, losing signal for no reason.

It was found that the fast dormancy feature is not compatible with all network carriers.
Therefore, fix for that (only for ROOTed phones) is available using a change to the build.prop file.
The needed change is detailed here:
ro.ril.disable.power.collapse=1
ro.ril.fast.dormancy.rule=1 change to =0

I have just spend 2 hours on phone coping first HTC and T-Mobile.
In HTC they told me there is issue with towers in my area.
I call T-Mobile and after 1 hour 30 min they figure it out they have technical issue with towers I ask why my wife's wildfire S is doing great "my personal technician" it depends on witch tower, witch channel and finally witch device so hopefully they will fix floating signal in 72 hours and that's will close m y case. If not HTC this time will not get any reason to denide warranty and will send me new phone

Standard CS BS. I think you'll find that the new phone will have the same problem. I believe it is a radio issue. I hear flashing the European radios helps but not brave enough to try.

I'm also having this problem.
Just randomly the phone will just disconnect from the network. Takes it about a few minutes (1 to 5 minutes) then it suddenly reconnects.
I've heard changing the micro-sim was a fix but that didnt work for me. I thought maybe it was a ROM issue but I've been rooted for about 2 months now (the issue started happening a day later).
Has anyone actually tried the build.prop fix?

Well after yesterday phonecalls TO HTC and t mobile situation gets a lot better.
Usually was 10 15 times per day today only 2 times on lunch time.
I don't know maybe my phone get a better day or they really fixing something
We will see tomorrow
Ps
I don't won't to root mine until devs will not find other way to s off. I don't won't to lose warranty

I think i read that's a prob with the US Tmo variant. Radio. Supposed to be fixed with latest RUU 1.84. If not, go bug HTC about it. Most likely their crap.
You could also try to flash the latest Radio from EU RUU 1.78 (0.16.31501S.17_2_10.23.31501S.10L) which is one generation ahead.
Check my MediaFire folder. Got the zip's in there. untested though. need be brave for this. And u'll need a custom recovery. and be unlocked of course.

Don't let HTC fool you. Their ICS radios SUCK. Same issues with the Amaze 4G when it updated from GB to ICS. Its not the towers
I think I'm gonna flash the EU radio just because I've got nothing to lose at this point.
Sent from my HTC One S using xda premium

The EU radios are not a problem for the device. They also work in the US. The problem is rather to get them flashed. I couldn't really swap radios. My device just didn't accept the flash.

I've also noticed it's gotten better so something is changing somewhere. But still the problem persists.
FWIW, I've rooted every device I've had since the G1 (6 devices[G1, N1, G2, MT4G, MT4GS and 1S]) and never had any issue initiating a warranty exchange or getting warranty service.

It flashed alright with success message but the radio didn't change. The chip wouldn't accept the write. Probably S-OFF required.
I've spent some two hours waiting at the hospital today and had enough time to check out the connection under bad signal conditions.
I must say, the HOS radio of the latest EU ruu is having severe problems with keeping the connection alive. Even my HD2 with gingerbread was a lot better. This phone suxx with bad signal. And this is not in the US where this problem has mostly been reported. This is in Germany.

I'm glad that I'm not the only one. I really like this phone a lot but with the signal dropping so much I really want to change phones. I bought it off wirefly so in pretty much stuck with it for the next two years.

It happens to me too sometimes. I just flashed the latest European radio and it worked fine for me.

I'm having the same issue. I've tried three different radios and several different roms and now i'm back to stock by using a restore I had before going crazy on my phone with the available roms... It seems that the stock rom drops signal as well. It just elegantly drops the connection and then reconnects whereas all the custom roms I've tried don't. Not sure what to do... I mostly purchased the One S for its hardware.
These are the radio's I've tried and they all have much of the same problem on my phone.
Radio from RUU_Ville_U_HTC_Europe_1.78.401.2
0.16.31501S.17_2_10.23.31501S.10L
Radio from OTA_Ville_U_TMOUS_1.84.531.2
0.16.31501S.16_2_10.22.31501S.10L
Radio from Stock T-Mobile US
0.16.31501S.02_10.18.31501S.08L
If anyone knows of a fix for this, I'd be more than happy to try it.

After hours with t-mobile personal technician they figure out they will replace my phone. Phone was bought on craig's list - something like e bay but free - and what's interesting T-Mobile will exchange for new one. We will see what's the story with new one
good luck to everybody

I`m having signal issues, as well. Whereas my wife`s phone has very good connection whatever the places we`ve been to, mine was struggling. And strange ups and downs with full and suddenly no connection at all within same area. I tried several ROMs and flashed the latest radio but still suffers. Regardless I`m in an area with full signal, when I switch to 3G then the signal instantly drops some bars. Very annoying....

Hi @ll. To me subject is over. Im using new replacement phone for 3 days and none of previous problems appear. I have no clue what was a problem. HTC blame t-mobile and t-mobile blame HTC. After all I get replacement device and 3 days phone work without any problem. Battery life is now much better because phone is not looking for signal. Still signal is floating but it is not going under 2 bars and device is all the time login in network.
So good luck to everybody. Greetings.

So even if I flash the stock ROM and put a custom ROM (like CM9 for example), this problem will not be fixed ??!! Even if I update the radio ?

[Q] My phone is unable to catch signals after downtime.

So recently in our area cellular services are blocked from time to time due to security measures. Now the really annoying thing is that my phone does not automatically catch signals when the service is back and when I reboot they are back. I have tried switching back and forth from airplane mode but to no avail it just needs a reboot. Infact yesterday when the services were back my data connection started working but there were no signals in the status bar and I couldnt make a call.
What could be the problem? I am running rooted stock rom 4.1.2 with matrix kernel. Or is this possibly a problem with the cellular company?

Its the i9023. Radio I dont know but I have never fiddled with this stuff so I suppose its stock radio. Only think I have done is root and custom kernel.

I used to have this problem, wanna know what happenned? My NS died (hard brick).
Most likely won't happen to yours.
The solution might be to flash a new radio that is compatible with the i9023. Radio's can alter your network performance and signal quality. If you're interested, here is a thread with different radio's:http://forum.xda-developers.com/showthread.php?t=1116884. Remember to always backup before flashing, and you can revert to your old radio by flashing it. To check your current radio, go to setting-->about phone, and look for baseband version.
An alternative is to try to flash a new rom, if you dont want to flash a radio.
Another alternative is a factory reset.
BUT, there is a possibility that our phones are designed like that, and none of these solutions will work.
Good luck! keep me updated

I have the KI1 radio. Well I asked a friend with an Iphone 4 and he says it "sometimes" happens with his phone as well so I suppose it's not something completely abnormal.
I don't actually have any signal problem apart from this issue. I never have to restart phone to get signals unless this specific timed ban on cellular services happen, I don't lose signals with some regular very short problem with network. I suppose it's just better to live with it than flashing new radios?
I might flash a custom rom soon so the factory reset solution will be tested then.
Did your Nexus S just randomly died? How do you suppose it had something to do with this problem?

I don't think it has to do with the problem, but i never found a solution because it died. Let me know how the new rom goes!

Btw there was also another problem that I didnt mention. Sometimes my phone refuses to turn on data connection and it only comes back with a reboot. This ONLY happens very rarely when I switch from wifi to data and never happens after data connection has started.
Did you have this problem? I just switched to CM10 yesterday and it has once happened so far but its not related to the ROM since it very rarely happened before as well.

I actually did have this problem! With my old ns. How long have you had this phone?

Its about 6 months old. I am experiencing this problem more whenever wifi is on for an extended period, so far I have had it 3 times with CM10.
I went back and forth to airplane mode and it started working so atleast didnt need to reboot.

I think this could be a 4.1.2 problem for me as I dont remember this happening previously.

Maybe try an ICS ROM?

[Q] Got GSIII and reception is terrible

It's easily 50% worse than my last phone (palm pre 3) and I've never had issues at my home with anyone's verizon phone.
I did flash LK1 RPM and Radio from this thread: http://forum.xda-developers.com/showthread.php?t=2007414
I'm not sure if that has any bearing on it and am also not sure if it was like that before. I did it all when I was in town.
Is there another radio I can flash and see if it's better? Or does the GSIII just have garbage reception on the outskirts?
TIA TIA

Diddo on all that..here is a list with all the modems.let me know if you find the best
Good luck

I've tried the miui 4.1
stock JB
and the mean jellybean one I posted above.

To be honest when I first flashed any ROM on to my GS3 my reception was terrible. Every ROM that I used was the same, I also tried every radio available.
My only solution was just to go back to stock which I did now this Stock ICS has me at 4-5 bars everywhere I go.
My last CM ROM had me at 0-1 bar in the same places.
I hope this helps.

Check to see if you have the updated prl version 15154. Do this by going to settings, about phone, status. I think that is an updated list of the towers and that could be your problem. If its not the updated version just shut phone off take out SIM card for 2 min and then just start it up and it should automatically update. I read this somewhere in another post and just figured i'd pass it on. Hope it helps.

Txs mike..I was on something like 14015::' 1 month of fiddling of different modems and radios

Unfortunately I'm already on this PRL
Going to try some ICS roms I guess.

I have tried each radio as they have come out with mixed reviews. Some are better than others for me but YMMV. I have found the latest VRLK1 is what works best for me. I came from the Thunderbolt, and I really miss the reception I had with that phone; however, that is the ONLY thing I miss about it. I am currently running CleanRom v5.0 and VRLK1. I definitely get the best reception, and can maintain 4G at work while the other radios would drop to 3g or 1x. I only hope it continues to improve, but I don't think it will ever be as good as I had with the Thunderbolt. Good Luck.

Did you try all the radios, even the ICS ones.

Mark as solved!
I tried every radio I agree the newest seemed to work best but still was ridiculous. Barely any service even though I had two bars at times. Not enough for a single call and had to be by a window to get spotty text service.
Traded for a lumia 822. Works perfect.

This is funny. Coming from the nexus this phone has way more signal and better reception. Instant switching from 3g to 4g and to wifi. Ive tried every radio and they all work very well. Tried on my nexus and all were horrible. Just my .02 cents but this phone rocks.

As others have said try out all of the older radios and use whichever one works best for you. Unfortunately, this phone is not particularly known for having a strong radio (and no software update is ever going to really fix that).
If you are really on a fringe area of service, this might not be the best phone for you. In my experience, Motorola phones have always had the best radios in the industry, and are the most reliable in fringe service areas.

[Q] Lolipop radio

Hello
With the final version of lolipop I have a lot of lost cell signal in place where I usually can phone without problem.
I think the new baseband 2.0.50.2.21 is horrible for me.
So can I flash the last radio of KitKat with lolipop?
Thanks

I don't see why it won't work, go for it, but at the same time be careful, back up your data, I've flashed radios for different versions of kit Kat on my nexus 5 before, but never from another version of Android.
Let us know how it turns out!

Just flash the Last kitkat radio all is fine. I'll see if the reception is better.

I'm having the same issue. Since I bought a used rooted N5 and who knows what they did to that KitKat build, the OTA update to Lollipop didn't work for me. So I flashed a full stock image of Lollipop LRX21O from Google's servers last night.
I don't recall ever losing signal in my home, but it currently is going from a full signal to complete signal dropout for minutes at a time. Was doing it in another location across the city this morning, so I know it's not a tower issue.
Please let me know if you find a stable radio that works with this build. Thanks!

Argh, flashed this last night. All seemed well for about 18 hours, then I have had several episodes of signal dropout this afternoon.

I'm actually seeing the opposite from you guys. Ever since I flashed the stock lollipop ROM and new radio, I've seen signal boost in places where it was terrible before. I would get horrible signal in my house. I now get a steady 2 bars, and my LTE hasn't cut out once. I guess its a Your Mileage May Vary type of thing.
I was on stock KitKat 4.4.4 before. I am with T-Mobile if that makes any difference.

Im another one wit signal issue I have horrible dropouts out of network, for about a minute with new lollipop radio
the worst part I don't have custom recovery any more to flash older baseband,
I'm from Europe. Is there any work around in settings or so please let me know.

OPO issues connecting to phone network

Hi everyone
Not quite sure where to start so I will go from the beginning.
I purchased a OPO almost 18 months ago now and since I received the phone I rooted it and originally flashed OxygenOS but found that that ROM drained my battery in hours, so then I installed Cyanogen OS 12.0(-YNG1TAS213) and found that almost everything worked perfectly. After a while I noticed that whenever I was in the car and went through an area that didn't have any carrier service I would need to reboot my phone in order to get my data to work again. I have put up with this because it hasn't been that much of an issue to me. (I mention this because it might be related to the issue I am facing now)
In the last couple of days my phone has gone from working fine to hardly working at all, until yesterday my phone just wouldn't connect to my carrier network at all and I kept getting a message come up as a notification saying 'Selected network (3 UK) unavailable'. When this happened I tried rebooting the phone, aeroplane mode off and on, clearing Cache and Dalvik Cache in TWRP and nothing helped. Yesterday evening after backing up my important data on the phone I went back into TWRP and did a factory reset.
After switching my phone back on again and setting it up as a new device I can now connect to my network, sort of. I don't get anything better than the shaded signal icon (worst signal strength), if I move around my house for example I lose service and if I go back to the same spot where I did have signal and flick aeroplane mode off and on again, probably about 40% of the time I get signal again.
A friend of mine is pretty good with this sort of stuff and has sorted previous phones for me but he lives 200+ miles away and can't really help. He thinks however that its likely to be the modem. I don't really know what to do so if someone can help instruct me as to how I can update the modem or suggest so other fix that would be awesome.
Thanks in advance.
Matt

Try flashing a new modem. There's a thread on it. There is no best modem, what works for you may not work at all for others, grab a couple, try one per day till you find one for you.
This always fixed that for me

Sorry I am completely new to dealing with modems. This may sound like a dumb question but does any modem work on any phone and its performance is based on what network you're using?

Nope modems are phone specific. You need a OnePlus modem.
Performance can vary based on location and carrier. You're best off trying a few, then remembering which is best for your. Modems aren't rom dependant, any OnePlus modem should work with any OnePlus rom. Some are made for different versions of Android though, I usually start with the most recent and work back.
Start here:
http://forum.xda-developers.com/oneplus-one/general/ref-oneplus-one-modem-collection-t2858734
Edit: this might have been part of the reason oxygen drained your battery too. If you've got the wrong modem your phone spend all day trying to negotiate a mobile connection. This kills your battery.
