EVO Service In and Out

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?

ICS Leak - Missed Calls and Data Drops on LTE

I have been running the ICS leak for quite some time now and haven't had any major problems with it until now. Ever since they launched LTE in my area I have been having trouble with my phone not receiving calls. When I finally talk to the person that was trying to call me, they say that it would ring twice and then go to voicemail. My phone never rings and I don't receive any notifications about missed calls. I have also noticed that when it does this, my data no longer works at all. If I toggle airplane mode, it will snap the phone out of it.
This problem seems to be growing in frequency. ATT tried to sell me some BS about the phone gets clogged with interference from travelling through low signal areas and they re-registered my phone on the network and told me to give it a try. My phone is still having this issue. LG had no clue what was going on with my phone.
Does anyone have any idea of what could be going on and what I can do to fix this?

New rom? Just in case something did happen with the rom somehow.

I'm also having the same problem on official Bell ICS...

Voice data is not sent over the LTE network but instead is sent over EDGE, HSUPA or HSDPA (gsm) networks. This is because LTE was designed to handle data only. Currently a few mobile operators are begging to launch voice over LTE capabilities (VoLTE). However ATT does not support VoLTE capabilities so whenever you place or receive a call your handset will switch to the gsm network to handle voice.After the call has ended your handset usually takes a few seconds to automatically switch back to LTE if available. During the time your phone is switching back networks your data will be inaccessible. If your phone does not switch back or your data never returns then you can toggle on/off airplane mode to reset it as you have mentioned doing. This should not be happening very often, unlike what you describe. What I would suggest is flashing HoNo's CWM official V20c ICS from att. This will update your phones baseband and firmware for your radios and I've also heard is more stable and has improved battery life. Hope I could help.

I had the same problems with the leak at home where I have a weak signal. Never had any problems with CM9 or GB. When I switched to the official rom all those problems went away. So I think it was just a baseband issue with the leak.
Sent from my LG-P930 using xda app-developers app

We ( my wife and I) got the same issue... With Bell.
So we sent both phone ( GB by the way non root ) to bell to get them repair ...
Sent back the phone... 1 h later ... got the same issue .. so they ( futuretel in Markham Ont Canada) dont find the issue, they just reflash the phone.
sent it and ... weeks later got it back ... lost it again ... but they change hardware and also reflash.
Now it's my turn ...
I'm still waiting for my phone because when i got it back, got issue ( probably firmware ) because I lost the speaker and speakerphone ... so if someone call me i was not able to ear them...
Sent back the phone again for repair and now i'm waiting.
Update my wife phone 2 day's ago with ICS from LG( bell ) and I dont think she got the issue.
If it's happening again, LG will have to step in because it's 2 repair for the same issue.
Since we are not alone in this situation we will be able to remove the hypothesis
of interference in our house!
And again ... when I was talking with someone from Bell support, I told them I would like to try custom Rom if the issue is still there...
The person agree with me... yes weard from someone from bell...
Other than that ... it would be good for people to "catlog" the drop signal / no voice service...
Some one have a good tool that can track that specific issue ?
Thanks!

Not connected to Mobile Network after being on Wifi?

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.

Calling issues

Just wanted to see if anyone else has been experiencing this or maybe knows a way to fix this. I have 2 issues with the phone calling on this phone. I had the 925T since launch and never had an issue with it. ever since i sent it in for repair, I've had a strange issue. Fist one is dialing out. When attemting to make a call, it takes anywhere from 3 seconds to 40 seconds before the call actually gets connected. this is highly annoying as i dial a number and it feels like forever before the call actually connects. my other issue is after the phon ehas been one for a few hours, I dont get any incoming calls. the phone will not show me any incoming calls at all so I don't even know when someone calls me. Ive tried everything i can. tried changing sim cards, updated the bootloader and modem, tried different roms, kernels, stock odin, everything. and its the same story no matter what I do. Anyone Have an idea of what it could be? It only works well after a fresh reboot. calls works without issues. hours later, problem comes back

I've had the same exact problem but I attributed it to using an AT&T Sim card on an unlocked T Mobile phone.
I've now rooted and installed Xtrostolite Rom with latest modem and bootloader. I've yet to have any issues. Good luck.

Anyone else have this issue?

I have this issue. It seems if i leave wifi off i do not ever have this issue. I live in a crappy coverage area so i have to have wifi on at home. I just reboot when i leave. I hate this phone....

You think the problem is WiFi related?

Yes. If i leave wifi off i never have the issue.

Still is happening. whether I have wifi on or off it always happens. It seem,s to be an issue related to VoLTE. When I turn LTE off, the issue dissapears. Updated baseband and bootloader to latest version and issue is still there. Have a custom rom and the issue is still there. go back to the tmobile rom and the issue is still there. thinkiing of going back to a tmobile firmware and turning off VoLTE in the firware then reflashing back to custom rom and seeing if that helps. if not, im selling the phone and getting the F version of the regular S6 and calling it a day. im done with carrier branded phones.

Interesting enough I haven't had this issue in the last 3 to 4 days. I wonder if it is AT&T related.

I have this issue. All the time. Unlocked from tmo, using straight talk at&t. This phone is the worst.

Anyone not on AT&T network having this issue?
I wonder if flashing the AT&T modem on TMO model will help.

Maybe you should get a phone from att.
If att service is better than tmobile then maybe there phone is better than tmobile's phone.

I've been able to switch between carriers on any phone that has the supported bands since the galaxy s2. The issue is with this phone. My mistake in buying it.

Please help!

same thing here its unbearable, using latest unibase and xtrestolite

I have tried a few roms and a few kernels. I have tried differ apns but att Sim in this phone doesn't work like it should. I was going to get a TMOBILE note 5 to use on att but now I know it's not worth the risk.

@stu5797, yea man, I wish I had a solution. I'm happy it's not just me, but pretty bummed that there seems to be no answer other than it just doesn't work properly.

I've noticed the issue only happens during peak hours. Can anyone confirm?

I was having similar problems after the 5.1.1 update so after a few troubleshooting sessions with TMO, they sent me a new phone. 2 weeks now and no more problems. First phone that I have not rooted and flashed..... I was also told by a store rep that a lot of people were having issues since TMO is upgrading towers for 12 band.

Are you still having this issue? I have the same issue and the same phone but mine is unlocked and working on cricket network. So yeah same problem taking forever to connect a call and no receiving calls mos of the time. No ring no notification of missing call. I been doing some research and find a temporary fix. Try going to settings -mobile networks and switch from lte/wcdma/gsm to wcdma/gsm or gsm only. But before do a test. Turn off data and try to make a call see how fast it connects then have someone to call your phone. If it works then this trick will work for you. Of course you gotta sacrifices lte speed . Basically having 4g only but at least will fix your calls. These problems seem to ve related to volte i been trying to disable it but there is no such option under phone app setting. I just dont have it. (I cann show some screen shots) so if someone knows a secret code or app whatever to turn it off i will appreciate it. My phone is a t mobile galaxy s6 edge.

[GUIDE] [HOW TO] Fix VS986 dropping down to 3G/H+ from 4G LTE

I've been working on a fix since a long time now. If you are in SD community then you prolly know me. Anyway I was able to fix this on two of my phones and it's working fine. I tested for 12 hours now. I'll also tell you in the end what problems I'm seeing. I'm also working on a fix for that.
I noticed that a service is started when the fallback happens but if I kill that service the network also dies. But if you follow the below method it safely starts a new service which kills the one that's responsible for killing the 4G/LTE
1. Upgrade your phone to 13B firmware
2. Root 13B
3. Now download Shortcut Master lite app from play store.
4. Now add these shortcuts to your favorites in the "Shortcut Master lite app". You can search for "LTE" and click on search button
LTEBandSelection
LTETestMain
LTE System Selection
CDMAPreference
5. Now click on "LTEBandSelection" and enable all the bands
6. Save and reboot
7. You now need to enable your data and turn off your wifi. Make sure your phone is in Global mode (in settings >> Mobile networks >> System select)
8. After your phone is rebooted open "Shortcut Master lite" app.
9. Now tap on LTETestMain
10. Select Click on CDMA preference.
Now choose Band preference and select "any"
P_REV_Preference ---> "MOB_P_REV 3
This is important.. EVDO Revision --> Rev A
11. "LTE Connect w/o IMS PDN" must be checked
12. Now go back to your main menu in shortcut master lit app
13. This step is very important. Changing the timeout is important. Tap on LTE System Selection
Except "Scan duration" add a couple zeros to all the other timers. For eg: T_mpsr timer (Min) is 200
The fallback timer will reset itself after reboot. But don't worry the configuration is already updated with the new value. For some reasons the shortcut master lite app is not picking it up.
14. Now finally click on "CDMA preference" in the main menu and make sure it has the value you set in Step 10
At step 10 or 13 your network should go away and your phone should complain about "no network". That's fine. just ignore the message.
Now finally reboot your phone. That's it. You should now have 4G LTE and it won't fallback to 3G or H+
The only problem is when I'm on a call my 4G LTE is dropped to 3G/H+. But after I hang up it goes back to 4G LTE after 12 seconds. I don't know if it's an expected behavior. But I'm trying to see if there is a fix for that.
I tested this with Tmobile. Make sure your APN settings are correct.

Not working for me on Cricket (AT&T). Still will always go back to H+, 4G LTE only works when I select CDMA.

That's great! I hope we can figure out also what we need to do to get it to work for AT&T, I am sure it's probably just some small tweaks required.

I will try it with my roomies att sim tonight. He has a nano sim, I need to find a sim adapter.

Awesome, thank you! worked for me T-mobile.
it initially didn't work but I had to turn data off then on.
It also cycles me to 2g speed for a few seconds sometimes but that may be due to poor signal in building.

Yeah It's due to the poor signal. I got that too. You can check your signal strength using LTE discover app.
But overall it's working fine for Tmobile. I'm gonna try and fix ATT tonight.

Is 13B the main thing in the solution? I've changed these settings before on 11A and wasn't fixed. I tried these numbers on 11A and still don't work.
Also, unless a phone supports VOLTE, it'll fall back to 3G/H for calls.

I tried in 11A and it didn't work for me. So I guess it needs 13B.

So I tried various combinations last night for AT&T/Cricket, but I was not able to get it to work. No matter what I tried, when I had 4G LTE, voice wouldn't work and whenever voice worked, I was back to H+.
If others are reporting that T-Mobile works reliably on 4G and nobody can figure out how to make this work for AT&T, I guess it's time to switch to T-Mobile.

No. Hold on. I have a solution for ATT too. I tried something last night. Actually while I was working on a solution for ATT I found that we don't even have to go through the steps I mentioned in my OP to solve the problem. It boils down to invoking a service and killing a native VZW service.
The ATT solution I have works but in low signal area 4G fades and it doesn't fallback to 3G or H+. I had to recycle data to get 3G or H+.

It's Working!!!!!!!!! Thank you!!!!!!!
You just made my life much better now!
I finally have a phone which is great and also finally have good reception!

No. Hold on. I have a solution for ATT too. I tried something last night. Actually while I was working on a solution for ATT I found that we don't even have to go through the steps I mentioned in my OP to solve the problem. It boils down to invoking a service and killing a native VZW service.
The ATT solution I have works but in low signal area 4G fades and it doesn't fallback to 3G or H+. I had to recycle data to get 3G or H+.

Yes, that same thing happens when you switch to CDMA mode with AT&T. Voice doesn't work then (obviously), but it also doesn't fall back to H+ automatically, when you lose 4G coverage you pretty much lose signal all together.

Yeah I know. I also know why that is happening. Actually I think it's a bug in the baseband firmware. But we can fix that issue by just overriding the command that was sent by baseband firmware.

Do you have a working fix for AT&T/Cricket? Is it different than the T-Mobile?

Ha! You are repped!
What root did you use? and steps?
easyroot?
did you split the file and merge it back?

I must have really bad luck or something. It doesn't work for me. The Tbsr_cdma timer resets back to 2 at reboot.
Edit: Appears to be working. Nice job!

Root? I just flashed the rooted sys image. That's it. instead of copying it in the FAT32 memory card just copy it to your phone's internal and you don't have to deal with split and merge stuff

If it drops out of 4G on a call then you're talking on 1X. So no video chat, no HD voice and no voice + data?
