Hi,
I'm facing a strange issue with my 9 month old Redmi 1S since last 2 days. Whenever I dial a number the call immediately disconnects and all I see is "Call Ended Not Connected".
I'm using 2 Sims, Airtel in slot 1 & Bsnl CellOne in slot 2. First I thought that maybe its a Network Issue but when I tried both the sims in a different handset, I was able to make calls. I tried an Aircel sim in 1S as well but same problem.
And yes I'm able to receive calls, 3G is working fine but can't make Voice Calls. The OS version was JH45 and I didn't update as I was waiting for Kitkat/Lollipop ROM. But last night I updated my phone to latest JH 56.0 assuming that it will solve the issue but the problem still persists.
Also, someone advised me to clear system cache from recovery which I did but still its the same.
Hoping to find some solution from the members here.
Regards.
So, nobody is gonna help me here?
I am able to make calls only if I prefix number with *31#
Why?
network calibartion issue with G3..status of RF CALL INFO is "not ok" please Help! :\
Hey my friends! i am new in this forum. i bought a LG D855 from Aliexpress and when i received the package and check the D855 i figure out that the hardware belong to the D850 and the software belong to D855. The device was fine except that the signal is constantly lost or up and down a problematic way it difficult to use the device! and does not allow to spend and receive calls normally, and no matter how I tried to fix the problem with change the networks(every option in WCDMA/LTE/GSM networks) or change SIM card to new one and make sure that my SIM is working in other devices or even to install applications that booster the signal of the mobile network! I sent the device to a lab that confirmed that is D850 and they flash other ROM (cloudy 1.2 for D850) and tried to fix the network issues but without success. i can to make or received calls or use internet but many times the signal is too weak or lost so i cant to make a call and sometimes the signal bar shows that there is a good signal but i still cant to make calls or use mobile internet. i entered to the hidden menu(3845#*850#) and discovered that the RF CALL INFO have a "NOT OK(DEFAULT)" status! other G3 or even G2 i checked have "OK" status..maybe this is the problem? how to fix it? thank you very much!! :good::good:

I've about had it with this phone internationally unlocked HTC 10 here originally had Oreo on it I downgraded back to nougat properly with the 2.51 latest firmware and now Sim is working on nougat but any AOSP ROM I use voice over LTE never works. I don't absolutely need voice over LTE to work but my phone does not always switch the connection to 4G to receive incoming calls either sometimes it would just stay on LTE and then the caller will be pushed to voicemail immediately. I can make calls from my phone fine but receiving has been a huge problem. I even tried the leedroid nougat ROM and it is doing the same thing as I thought it was an AOSP problem but that can't be the case as it possibly something with my firmware? I just want this headache to go away and receive my calls properly again! Any help will be greatly appreciated
Carrier is tmobile
So I've discovered that volte does not work with AOSP ROMs but it seems when I get a call the LTE does not go down to 4G to let the call be received is there anything I can do

Hello, I bought an S7A on eBay. I unlocked it with the GSM unlock code provided. Everything works fine, except ... I can't make or receive calls. When I make a call, no ringing tone, and it hangs up 20 seconds later. When someone calls me, the same, then they come across my answering machine.
I'm on the latest version of Oero available, no root or whatever. From what I saw (on GSMArena), the phone uses compatible frequencies in France.
I am at carrier Bouygues Teelcom.
You have any ideas ? Thank you !
PS: I translate from French, please be indulgent!
Same problem, this phone does not work in China
Since then I have understood the real problem: the phone cannot switch from the 4G network to the 2G network for calls on its own.
I don't know how I did it, but now I can make calls without any problem, but switching to 2G is very long (15 s).
I specify that it is impossible to use VoLTE to circumvent this problem.
For receiving calls, the phone does not switch to 2G and the incoming call still fails.
But I can force the 2G network (With the Samsung Band Selection app). And there, incoming calls work, but we only have 2G to surf.
When connected to WIFI, the phone automatically forces the mobile network to 2G, so incoming calls work without the application mentioned before.
Hello everyone, my phone is LG G8 Korean SK telecom, i have been using my phone for over one and half years without mobile network problem, except its signal quite weak and the phone restarted frequently. Last week it suddenly lost signal (no signal at all, not rotating icon) though it still prompt me to enter SIM lock password. I had tried different ways like factory reset and even flash kdz to older and current Android version but nothing happened. Can anyone encountered this case help me ?
Hello,
No fix for you but I also have a lot of calling issues with my Korean G820N (LGU+). Most people calling me get the ringtone and my voicemail but I have NOTHING on the phone..... So, I miss calls and was forced to install a voicemail app to know if people called me or not....
I'm thinkign to flash a US KDZ but if you could give a quick feedback of your problem it could help me.
