[Q] GSM(2G-EDGE) Reception Problem with Stock ROM - One (M7) Q&A, Help & Troubleshooting

Hi,
I have problems with Stock ROM, hope someone can help.
I was using with a GSM(2G-EDGE) SIM card with HTC M7, but the voice quality of voice call is not good, the voice sometime loud and low, and sometime unstable.(With full bars of signal)
And I tried to replaced with a 4G-LTE SIM card to test, and there were NO any problem with voice call.
But, If I try to change settings with a 4G SIM card, force it to run with GSM network, the voice quality problem happens again.
Could anyone tell me, is this a general reception problem for all M7 device? Or this is just my personal device problem? I have sent my device to HTC for repair, and they have replaced the receiver in the phone, the problem has little bit improved, but not good enough.(Compare with HTC ONE X)
Hope someone can help.
Thanks.
Regards

Hope someone can help

Not able to make phonecalls and batt. emty fast!

Hi All,
Something weird happened yesterday, my tytn II stopped working normaly.
I cannot make calls anymore and people calling me get my voicemail, although it shows full reception (t-mobile). The only call works, is calling my voicemail. I didnt change anything in the phone prior to this problem.
Also the battery is dropping down very fast. Like 50% in 5 hours without using anything...
I putted my sim in another phone, it works fine, so the problem lies within the phone. I hardresetted the phone but the problem remains...
Anybody had the same problems and/or knows how to fix this???
I have an original HTC tytn II on tmobile network.
THanks!!

found comparing problem here, probably same problem:

Thanks!

Hi,
I also have the same problem you write about. It also happened for no apparant reason. I notice that I can make calls to other mobiles that are close to my phone in proximity... odd?!
I've sent an email to HTC ... waiting on a response.
I have started getting the same sort of problem. When I try and make calls - it just won't connect. Sometimes a soft reset works - but not always. People cannot call me and I get messages about missed calls and voicemail messages.
It's starting to make my Orange TyTnII virtually unusable.
Suggestions?

Calls are disconnected

At my company we use more than 30 S730's which have the same issue.
Randomly, while people are having a conversation (mobile - mobile / mobile - landline),
the connection is being cut off resulting in the inevetible 3-tone "Your call is being disconnected" sound.
Does anyone have this issue? I'm trying to figure out if this problem is related to the combination of Vodafone and the S730,
the S730 itself, or that there's something else that's dark and dangerous and wants to take over our phones.
Regards,
Korny
I dont use Vodafone, and only have dropped one call since the phone released due to bad reception where I was. Whats the connectivity like when your dropping calls? Anything causing interference or generating a signal that could bump you off?
Do you have bluetooth on?
With a t-mobile sim I couldn't make or receive calls when 3G was active, turned it off and it worked fine. This does not happen all the time.
Does that help?
edit: I have bluetooth off, as per question above.
Flame-bait:-
I've only had a quick search so I'll keep trying, but if anyone has a link to anything to automatically make sure you use GPRS unless you ask for data, then I'd be grateful.
Also links to reg keys or anything as I am not shy of a bit of tampering.
Something similar to mortscript for kaiser...
I have the same problem with my HTC S730. I think that dropping calls is someway connected with poor signal, but not that bad to dropp call. Also a WiFi may have some impact to this, but i'm not sure of it. I'm using phone in Poland 3G mobile operator.
Same here
Hey Guys,
My s730 seems to have the same issue. At least its similar. Sometimes incoming calls are auto-denied just after one ring. The problem is gone after a cold-start.

I recently have again this problem and even cold restar didn't help After another restart it finally start working as it should. What was most strange in this is fact that I received sms, but I couldn't make a call!
I wrote to HTC about it, but as usual my questions were ignored.
EDIT: I had enough of this and I flashed my radio from 1.58 (shipped) to 1.64 version. I hope this help and resolve my problems.
The new radio didn't solve the whole problem with disconnecting calls, but now it happens a bit rarely And battery life also has slightly improved.

Serious reception problems

I'm experiencing reception problems with my phone. The first two weeks this was not a problem but end of last week and yesterday and today I'm having troubles with the phone. I have between 2-5 bars (average 3) when talking and I'm always calling from the exact same location and same room (working from home).
The problem is that after a few minutes I can't hear the other person. The person calling me can hear me without problems but I can't hear him. So I hang up, call back and the same happens after a few minutes.
I have tried with and without headset and also tried to soft reset it without result. Any ideas what to do? Anyone else experiencing the same problem?

No idea sorry! But I don't have that problem. Do u have a SIM card from another provider to check?

Yes, I might be able to try that or I'll try to get it replaced. Looks like no one else is experiencing the same.
I to am having some serious Reception issues but im with Optus in Australia. When on 3G at home.. cant make or take calls. So i have turned it to just GSM so i can get calls and make them.. Sometimes I did get calls and messages on 3G at home.. but today, it just wouldnt do anything..
There are updates from other counties which seem to have a radio update.

Hi,
Is there any way just to extract the Radio upgrade ?
I have my Diamond 2 in french, and want to keep it like that.
I wrote to the french HTC Support, and they just ask me to :
- Hard reset the phone : Done and useless
- Change the sim card : not done as the sim card I used is completely new
- Disable encryption : disabled and useless....
So the only solution will be a radio upgrade only.
Thanks

[Q] Weird voice call problem

Hi,
I have a really strange problem..
I've got my new HTC Incredible S one month ago, and everything was fine.
Recently, people were telling me that in the middle of a call, my voice turns out into a noisy voice!
I tried to make calls to my phone from another phone, and after few minutes, the voice really changed into a weird voice (really different than my own voice) plus a lot of background noise (it looks like the phone has switched to the voice cancellation mic instead of the regular mic).
During the call, when this problem happens and when I switch to headset or turn on the speaker phone, the problem is fixed. few minutes later, it comes back again.
I checked for viruses, no add-on or 3th party phone applications installed.
Shall I do a factory reset?
I don't wanna lose my apps, settings, contacts and data
Please help!!!
Same here.
Maybe this one helps:
http://forum.xda-developers.com/showthread.php?t=1081356
didn't try (couldn't try), because no root here....
My phone is not rooted neither.
Any solutions?
Have you tried to do a factory reset?
I don't think it's a hardware issue; because it's been working fine for one month with no trouble.
No, didn't try a factory reset.
And i also think, this is a software issue, but no clue what could be the reason for this behavior. Sometimes voice call just works fine and sometimes it doesn't...
Yeah same here. Sometimes It goes fine & sometimes not. I think I will do a factory reset soon and will let you know the result.
Sent from my HTC Incredible S using XDA App
Hi,
I did a factory reset (or what they call a Hard Reset).. the same problem still happening!
I event went to the telecom company, and they replaced my SIM card, but still the same
Any clues????
Could it be a defect handset ?
Now I just figured it out!
It was a problem with the GSM provider!!!
They told me to switch to 2G instead of 3G, and it really worked with no troubles.
I'm happy now that my phone has no defect
thanx. will try that. but do you know what exatly was the problem with the gsm?
I think the problem is in the GSM tower that is close to my house (this is what the communication company said).
My big brother has HTC Incredible S too, and when he switched to 3G, he suffered from exactly the same problem!!!
I don't think the two phones are defective; since we bought the first one from USA and the second from here.
Just try to force the phone to use 2G instead of 3G. you can do that from:
Settings >> Mobile & Networks >> Network Mode >> GSM only.
Selecting GSM only = 2G
Selecting WCDMA = 3G
Thanx again. I will give this a try
I had this problem once but after changing to 2G as u referred it worked just fine
There is widget on market called "2g-3g on off" for faster changing between these two modes. Very useful when you need 3g for faster web
aaaaaand. it seems to work. strange. unfortunately its 2g and not 3g....

"Call ended" right after dialing

First of all, I want to say that I found people with the same issue using Android everywhere and with a lot of different phones, so it's probably an Android bug rather then Moto X itself, but I wanted to leave my report.
I came from an S3, which suffered from the same problem when using Cyanogenmod. When using official Samsung ROM everything worked as it should. Now, I'm getting the same issue on my brand new Moto X.
When I try to call someone, sometimes it just doesn't call, after I press the dial button, it just hangs (without ringing) and finished the call with a "Cal ended" message. It happens randomly, and sometimes I can't call anybody for like 2/3 hours.
The simcard has been changed from the S3 (micro) to the Moto X (nano), so it's probably not it. Also, with the Samsung ROM it didn't happen.
I can still receive calls and messages, and the signal strength is fine most of the time. I just can't call.
Today I faced this problem and then I tried calling from my girlfriend smartphone (samsung ace IIx) at the same time, which is from the same carrier, calling to the same number, and it just worked fine. Mine still didn't work though.
Here is a thread on people on xda facing the same problem, but with a different phone: http://forum.xda-developers.com/showthread.php?t=2351227
Don't know what to do.
i've had the call not go through as you've described, but have never had a phone not let me place "any call" afterwards. i always chalked it up to poor performance (limited RAM, too many processes, etc). My DROID3 would do it and often times when it finally did make a call, there was zero sound and I would have to reboot the phone.

Hmm, it doesn't seems like poor performance. I ended up every task and it still happened.
However, I noticed that when I check the "2G ONLY" option it comes back to work. Maybe it's something with the HSPA/HSPA+ connection.
it could be completely carrier dependent then. my experience has been with vzw.
Moto X "Call Ended"
I have experienced this same problem in Houston on the T-Mobile network after switching over to Android. My T-Mobile rep told me they have had towers vandalized for copper which has impacted service for them, I believe he said it was about 15 towers and 10K a pop to get things corrected. What gets me is I was on a Bold 9900 and while I had signal problems in the affected areas of town I didn't not experience the "call ended" issue. I can also call other T-Mobile phones from those same areas but not land lines so to me this seems like a possible network routing issue which I have seen before between specific carriers.
If the problem does continue I may have to switch carriers. T-Mobiles service was previously outstanding in Houston but recently had not been great after the 4G LTE upgrades. I support multiple hospitals and need service to work correctly and will work with the T-Mobile Engineers to see if I can make headway on that front. I noticed another MotoX user reporting he only had the issue when flying in to Houston for work and that everything worked for him outside of Houston. His solution was to operate in 2G mode which for me is really not an option. I have to handle a lot of tasks over the network while on calls.
Anyways I would appreciate it if others could post if they are experiencing these issues and give as many details as possible so we can try to isolate the root cause of this problem and if found to be a carrier issue we can escalate with them. Thanks

Call Ended Issue Resolved
Hi All,
I see this Call Ended Issue in many brands. So I assume the error is a combination of the Network along with the SimSlot.
I tried various combinations for my Moto-E mobile.
Before i post the solution i found, Let me provide a brief about the problem.
I use Vodafone network on sim1 slot and Uninor network on Sim2 slot. I started facing the call ended issue on my sim 1 vodafone network.
I inter changed the sim's and found the network working absolutely fine. This makes me to understand that the sim1 slot with the vodafone carrier has some network issue where that IMEI code has some problem.
i tried to place the vodafone sim again on the sim 1 slot and found the problem persists. So i came to that conclusion.
Hope this might help you and provide a instantaneous and temporary resolution.
Thanks,
Praveen.
Call Ended problem still going...
Hey,
I just rooted my Moto X (XT 1053), like 5 min ago, in the hope to fix this same problem. I`m no programer/developer and have nothing against rooting, I just don`t think I`m that kind of user. Anyway, about a week ago my phone started to drop my calls right after dialing. I restored factory settings, updated it and nothing worked. I took it for service and they offered to charge me 150 bucks to restore factory settings and update the software. So I was kinda forced to root and try to fix it this way. The problem is that I probably don`t understand half of what you guys say, so if there are any kind souls out there, please help me out.
To sum it up:
- No Sim Card error
- I get carrier services and can use mobile internet (3G because 4G is still too explensive here in Brazil)
- Directly drops my calls
- Won't receive calls
- Won't send or receive text messages via carrier (just over 3G or wifi)
I`ve tried another carrier's Sim Card, no go.
I`ve tried my Sim Card on another phone and it worked just dandy, so I really don`t think it`s carrier related.
I`m running Android 4.4.3, as the other updates weren`t available for my phone via Motorola. I thought maybe updating to a newer version of Android might do the trick. I just have no clue on how to do that on a rooted phone... or on a non rooted phone for that matter.
Can anyone give me any tips/pointers/etc... ?
Thanks!
I have the same issue with my moto x on Verizon. Have you been able to figure it out?
