Hangs up while dialing

Hi,

Since purchasing my galaxy s6, the device has been hanging up the call about three seconds after dialing - just saying "call ended".
After dialing a few times the call goes through.
The problem persists with different service providers.
It seems to be a software issue as it resolved one day suddenly after returning from a trip abroad with the device, but has now returned after upgrading to android 5.1... :(
Any ideas?
Thanks!

My Firephone Hangs then Reboots Often when using Mobile Network

Hi guys, I just recently bought a new FirePhone now on CM11 however what I noticed is that it keeps on rebooting like almost every time an application uses the internet connected to mobile network.

Has anyone experienced similar case as this? I tried not to use mobile internet and instead used Wifi and internet connection worked fine and there were no reboots.

I am using CM11 release of 09/15/2015. I followed well the steps on installation. Performed clean install and even installed GApps pico but still same outcome.

I hope someone can share what was done to prevent the sudden reboots when accessing mobile internet.

Any WIFI hangs in Saved, but it wont connect.

It's been 48 crazy hours since I'm having this annoying issue, and after Google even my soul and read the same amount of words as 180 bibles... I give up and write down what's happening to my Note 4.

I have an international Note 4 (N910F), with stock Android 5.0.1 (N910FXXU1ANK4), which was working 100% normal until 2 days ago where - just for curiosity - I installed Cyanogenmod 12.1 to see how it runs on my phone. After 30 or 40 minutes I returned to stock using the same stock Android 5.0.1 which I have previously downloaded from Sammobile.

Before install I did a clean full wipe, root again, and put it just like I did 48 hours ago. The only difference is now wifi scans for connections, it sees wifi connections, but it wont connect. I've flashed the whole firmware countless times, did a full wipe with TWRP and stock recoveries like 15 times, format partitions countless times, forgot connections, put details from scratch again and it just put them as Saved, but it wont connect. I tried to make a totally open connection and nothing... so I'm really out of ideas here.



Any suggestions? Any miraculous app? Please guys help me.

Thanks in advance.

King regards.

PD: FYI I'm the only one in my wifi channel.

Resurrection Remix Hangs At LG Logo

So I follow the instruction, flashed the bumped bootstack, the resurrection remix rom and recommended gapps, but no matter how many times I tried, the phone simply hangs at LG logo. Does anyone knows what the issue might be? Oh, my model is d800.
