Hey all, I'm more of a search and learn user than a poster, but I have yet to find an answer by searching alone, so here goes.
My EVO tends to dip in and out of signal on a regular basis, but more often then not when I'm driving. For example, the phone will go from having 5 bars, to none, then back to 5 in a matter of seconds (id say about a minute). It did this 4 times on the way home from work today. I just came from T-Mobile, and I cant recall this ever happening on their GSM network. Is this a phone issue, or a typical behavior of Sprint and or CDMA networks?
Thanks!

mine does this also...and i came from tmobile too, i dont think its relaly losing service... b/c if u lose service there will be an X next to the bars...i think it might just be switching towers and not doing it smoothly... b/c whenever it dips i try to make calls to make sure i still got service and what do you know it always works :/
also sometimes i notice it dips to 1 bar then back up in a matter of seconds... any idea anyone?
Yeah I agree that I still have voice service, however my data does completely stop. Its a pain cause all my background downloads get interrupted and often broken.

I noticed it on occasion on AT&T but that could be because of their ****ty 3G network here.
I have noticed it on Sprint too. I never completely drop service, but I do frequently drop from 5-6 bars of EvDo down to 1-2 bars of 1xRTT then it jumps right back up. It seems to only happen when I'm driving fast

hmm not sure... i also do notice i get error codes when sending txt's sometimes... like error 107 or 97 and i think 32 before... but it hasnt occured recently... its mainly when i send txts back to back super fast... or if im sending one when someone is sending me one...
so i dunno if the port from tmobile is just bad? or what...
forgot to mention 2 of my friends evo's do the same thing... they live near me... and well it does it but i dont think as often as mine... not sure... but it seems liek all evos do it... maybe just bad service area?
I definitely don't get error codes, but the service going in and
out is really annoying. So annoying, that i may drop Sprint and return my evo.
hmm then i dunno i would call and ask, i think sprint jsut has spotty service for you, have u check the tws?
(time without service percentages)?
and did u do the cmda auto prl? after i do that it helps ALOT
How do you check the TWS? Also, by auto PRL, you are referring to the "Update PRL" feature in Software Update right?

go to settings and battery and batterystatus and check cell standby, then the prl thing is to set it so its CMDA and not GSM setting...
its not the update PRL there is a thread about it
http://forum.xda-developers.com/showthread.php?t=717785
"If your phone is afflicted with TWS > 0, try this procedure.
1) In dialer, dial *#*#4636#*#* to enter "Testing" app.
2) Under Phone Information, set Set preferred network type to CDMA only.
3) Exit Testing by pressing "back" key.
4) Enter Testing again.
5) Set network to CDMA auto (PRL).
6) Exit Testing again.
This fixed my TWS, and the settings stick on reboot."
btw u MIGHT have to do this everytime after reboot
Done.. I appreciate the advice. We'll see if it works. I wonder if you can use the "Network" app to do this... Also, I applied the verizon PRL hack and it worked.. However, I'm just afraid to use it before I test if it charges roaming.
Also, TWS is 3%
evo has NO roaming charges on the plans... whatsoever...
hmm your tws is low... i dont see why your signal just drops like that... mine isnt as much as you if your saying yours does it allt he time... but mine does it and it hasnt bothered me...
werd... my phone just now did the no connection to 3g... anyone else figuire out what this was?
Hey.
I have a big problem with my desire. The phone is fully working, but when it goes into standby, and I try to turn it on using the "power button" at the top, the keys light up, but nothing comes on the screen It just doesn't turn on again.
Any ideas? Thanks!
In the general section on the desire forum there is a topic related to defective proximity sensor. i,m a new forum-user so i can't make a link yet
Thanks for the help so far, but couldn't find anything that solved my problem :/ Have to restart the phone every time it goes into standby
Like many others, I am also experiencing this standby-of-death (SOD) problem: the lights in the buttons under the screen turn on, but the screen itself stays black. I have found out that it has to do with switching from 3G to 2G networks: the problem occurs after I have been at places where there is no 3G signal, but only 2G. For example, after a car trip or when going into the basement.
A workaround for this problem, is to type the code *#*#4636#*#* in the dialer. You will then end up in a hidden menu. By choosing "Phone information" (first item) and then scrolling down in the next screen, you can change the "Preferred network type". By default, it was set to "WCDMA preferred" on my phone. After I changed this setting to "WCDMA only" (so, 3G only), I have not seen the SOD issue anymore (for 4 weeks now, before it happened almost daily).
A disadvantage of this workaround is that the phone will never use 2G anymore. So, when you are at a place where there is no 3G signal, you will be disconnected (i.e. you cannot receive phone calls). As an alternative, I have now reverted the setting to the original value ("WCDMA preferred") and I have installed an older radio image (version 32.44.00.32U_5.09.05.30_2), which is considered to be more stable by many people. I'll test and see whether the problem reoccurs. If the problem stays away, it is apparently a software (radio image) issue. If not, it must be a hardware issue.
Anyway, if anyone has additional information about the root cause of this standby issue, please let me know!

OMG I love you!
Seriously this has been doing my head in for weeks! I have posted a couple of times in this forum. First time, constantly remvoing and replacing the battery left me with a bricked phone. HTC revived it under warranty but after a week I got sick of Sense (and the poor battery life) and tried rooting again (tried Redux and CM7) but the problem came back. Makes sense because it works fine around Bristol (loads of 3G) but constantly SODs in Bournemouth (flicks between 2G and 3G at my desk). Also, just had data off for a few hours and didn't get SOD once.
I am not up on the lingo yet as I am fairly new to rooting but running Baseband version 32.49.00.32H_5.11.05.27. Is this the radio?
Please keep me posted on the older radio version. Shouldn't need a long test period, just need to go from a known 3G area to a known 2G area while locked.

Yes it is the radio.
I have got GingerVillain (Based on CM) and I use the Power Control widget to switch between 2G and 3G. You can customise the widget (just add it to a screen) to get this feature.
I haven't got any 3G around my house so I don't need to activate it all the time .
Yeah Redux has a similar thing so I will use that until a proper solution is found.
Small update: enabling 2G only didn't fix the issue (I think 3G only is okay) so perhaps the issue is with 2G rather than switching between the two.
Instead I am using an app called "3G Data Only!" so that 2G can still be used for calls but not data, working great so far.
I have tied the latest Radio (32.56.00.32U_5.17.05.23) and the problem does not go away.
How come this problem doesn't occur to (many) others? Could it be related to your network provider? Maybe you could change the SIM with another, from another network, and see what happens. Also, you could make use of the phone warranty - if it's still covered by it.

On o2 (in UK) right now, will try out another sim later. As for warranty, never had any issues on non-root Froyo Sense so can't do anything.

Try to change the network, say, from O2 to 3 or Vodafone. If your Desire is branded, there is a free way to unlock it - just look for Desire SIM-Unlock utility in the forum, by sieempi

I also have this SOD issue with the older radio ROM versions, so installing an older version is not a solution.

Great, I'll try this application! Would be very nice if that fixes the problem without disabling 2G phone calls. I never use 2G for data (too slow anyway), but I would like to be able to still make phone calls when out of range of 3G cells.

It might be, I don't know. I'm using a Telfort SIM, connected via the KPN network (Netherlands).
3G data only works a treat for that, you can make calls.
Found with the old radio that it is a lot more stable than the new radio but not 100% perfect. Where I work I only have 2G and it would SOD all the time but now it doesn't. However on a journey I make with intermittent 2G/3G I did get a SOD.
Sent from my HTC Desire using XDA App
3G Data Only doesn't work well enough. The SOD issue does occur less frequently, but the phone still hangs sporadically. So, if have disabled 2G completely again.
You should try Insertcoin. I haven't had this issue since I started using IC v32 a2sd.
Hi there. So i get the same thing on mine. I thought I should report my experience.
Had it over a year old then all of a sudden it started acting like this
heres what i tried
Factory reset, rooted it twice, boot with no sim, no SD card, dismantled it via instructions I found on an android forum to check for loose connections, gave it to a friend who ran some different roms, overclocked it, underclocked it. Its currently on the Oxygen rom, no difference. I tried the secret menu from page one of the comments. I tried living with leaving the screen on for 30 mins..but its so impractical
I should add that if i leave it for say a couple of hours, the damn thing comes on just fine. Its only from being on, to off, then back on..
I think its hardware related, maybe something to do with the power being held back for the screen or something. All i can say is that its really doing my tits in and i'm currently using my old phone which is functional but not as fun.
What can i do next...send to HTC, i'm out of warranty but their repair centre can still have a look, or buy a faulty phone off ebay and harvest some parts...
I dont want to give up on it, because apart from this the phone works fine.
guys i had this problem too, when i force to use 3G only everything works perfect but in area with no 3G signal your phone become useless cuz you are out of network, i also had a self-rebboting problem and i sent my lovely desire to htc repair center, they replace mobo and now i am waiting to receive my phone back and i will test this issue, if everything will works correctly in 3g/gsm etc you guys need to do the same and sent your phone to repair,
This has been a frustrating issue I've been having pretty much since starting up my T-mobile service about a month ago.
To start off, my G3 is unrooted and on the latest stock software version, 20e.
I use Wifi calling often because I get 0-1 bars of reception at work. All seems to work well until I go outside and try to make a phonecall over the voice network. I'll have plenty of signal bars, be connected to 4G even, yet when I try to use the phone dialer to make a call it will say "Not connected to Mobile Network." or something along those lines.
I haven't done extensive testing, but I believe the other day I toggled the "Mobile Data" off then back on and was able to make calls.
Has anyone else had this trouble? Is it something possibly to do with Wifi and/or Wifi calling?
I believe I could make a phonecall using Hangouts when I was off of wifi, which tells me that the data part is working, but not the voice network.
I contacted T-mobile support, but they just had me do the "typical" things, like shut down the phone, remove the battery/SIM, start everything back up. And sure enough, it worked after that, but I'd rather not have to restart my phone or toggle stuff to get it to work as it should without any hassle.
Thanks!
My wife has the same problem after the 20E update. Her mobile is stock as well. It did not happen on 20B.

Off the top of my head no. I'll dig around a bit and see what if anything I come up with.,
From the digging I did I can't seem to find any help. The only thing I can think of is to factory reset it thing and see if it helps. I am going to do do it on my wifes phone tonight.
Yeah, that's what I was thinking too... I'm not really in the mood to deal with restoring all of my apps and whatnot, so I'll hold off on the factory reset for now.
If you remember, could you let me know the results? If I know for fair certainty that a wipe will fix the issue, I might do it.
Thanks!
It's a network problem and it is worst on Samsung phones. I recently went and got a new sim card and it seems to have fixed it. I read it is because if you live in a area where there is poor coverage it causes your sim to where out fast.

This started happening before my first month of T-mobile service was even up with a brand new SIM. I'm not saying that it's definitely not a SIM issue, just would seem unlikely that it's worn out that fast.
Mobile out of Network-Tmobile - Android
I;m having the same issue, turned phone off and on, checked Network connections everything looks fine, but now able to receive and send texts or make calls.

Possible fixes for this is flashing the latest radio, I believe it's UVMC6. Works fine with my phone (I live in Mexico and 2G works fine)
EDIT: Sorry, I realize that you have the latest radio, my bad
I remember I used to have this issue too, what fixed it for me is choosing manually my network operator, available in the phone network settings. It was either choosing manually or automatically, I can't recall which one I chose, but it fixed the problem. I now have it in automatic and it works and from time to time when I travel to the US close to the border, my phone cannot decide if it wants to go with T-Mobile or my network (Movistar) so I change it to manual and select Movistar and works just fine, so maybe all you need to do is change from Automatic to Manual, or vice-versa. Hope that can help

Hey,
I tried choosing manually, it did say it was registered on network, but that's it, signal bar remained empty and it still said emergency calls only. At times the signal bar fills up, but saids mobile network unavailable when I try to make a call.
Appreciate your assistance tho
I managed to make a log of when I switch to 2g, If that would be helpful

Wish I could help, but I don't know what to do anymore. Why don't you just stick to 3G? There are some places I can't use 2G so I switch to 3G, I just deactivate data when I'm not using it. I sometimes lose 2G signal too, but that's mainly because I am inside a building with thick walls or I simply don't get 2G signal, happens from time to time on certain places, like my old work place for example. I would either get low signal or no signal at all.
I wish I could help, but even I don't know what to do. Best of luck to you
Hello guys!
My HTC One M9 is giving me some headaches!
What is happening is that if I'm inside home, I cannot get GSM network. This happens for both voice and data.
As soon as I go outside, I get the 4G working like a charm. I could live with this, but sometimes I need to sleep inside home
From my troubleshooting around this, I found out that if I reset the phone, there is no change.
Reset network settings does nothing.
Sometimes if I restart the phone I get network, but it goes away quickly.
No change if I enable and disable the flight mode.
What does work is if I set the network mode to be 2G only, then I have the network and all works (except the data with some low speeds).
The phone is now with the build 4.28.401.3
I've tried different RUUs and it is the same thing.
Can someone help to try to understand what can be the cause for this?
.... could it be a network issue?

Yes, I have noticed a similar issue and it has been very annoying. I know that in my area, I can get 4g+, but it only picks it up sometimes and goes away. Also, I have very strong 4g signal around my area but for some reason, it always uses 2g and sometimes gives my 4g, but rarely. I think it has something to do with the way sense automatically switches between networks.
Try typing in *#*#4636#*#*, press phone information and where it says some thing like lte/wcdma auto and select what you prefer. I chose lte/wcdma and now I only get 4g and 3g signals which is acceptable. If you want GSM or something, choose it as preferred. Play around with the different ones and see which is best for you.
If not, try a non sense rom, I don't know if that would help but give it a go.
Hope this helps,
Jev
Well, I've tried different settings, but it does the same. Only when using 2G or GSM only it works inside home.
I am yet to test with a non-sense ROM. Because for me, having an HTC is also because I like sense.
Either way, it seems to me that it can be hardware and not software.
Do someone knows what controls this network settings? A different board? A chip?
You mention applying the Nougat RUU for your phone - did you first update to Nougat via OTA?
The update was made via OTA. A regular update but this was already happening before the update.

:-/ Darn. Good on you for updating correctly, for sure, but that eliminates the problem I was anticipating.
Could be a carrier issue. If the other phone that has a good signal is an m9 then obviously your phone has a fault. If it was a different model and/or brand then you should learn something about "industry standards" as far as signal detection and interpretation goes. Just because one certain type/model/brand of phone has a good signal it doesn't mean another "has to".
