call quality / audio quality drops during call topic

Hello

I have an interesting problem.
During a call the sound quality suddenly drops. Then it not possible to continue this call because of the bad audio. It usually happens after 10 minutes of calling, sometimes less, sometimes a bit more.

It happens with CM11, CM12, and Omnirom. It also seems related to the LTE network function - not sure though.
I recently switched my operator and got a new sim card. This new operator is providing LTE and since then this happens so this might be related to that problem.

Any idea about that?


This is the log I get:

[Q] [Help] Battery Drops to 1% from 20%[KK ST18i] topic

My Xperia Ray Running on Kitkat 4.4.4 is facing a sudden battery drain. When the battery is about 20-25%, It suddenly drops down to 1%. :crying:
Is there any method to solve this?
I had tried flashing the ICS firmware. and again flashing the Kitkat Kernel. This did not fix the issue.
Can anyone suggest a fix for this?

Bluetooth drops when calling out or receiving topic

Hi everyone,

Probably a longshot but here goes.

I have a Plantronics Voyager Legend bluetooth ear-piece. It pairs well and the sound is awesome. Some while ago I started having some problems though that the piece disconnects/drops when I receive or dial out. It's fixed by pushing the 'headset' button again to connect but it's quite irritating that I have to do this everytime. I have tried a lot of roms and kernels without avail. Most of them just made the bluetoothproblem worse or made the bluetooth fail totally. I am now running ArchiDroid V1.7.18 with boeflla kernel and it's the same problem as I had with original Stock.

Anyone else had this problem? Haven't had the opportunity to try with any other bluetooth device in case it's the plantronics that's the problem. Is there an app that can keep the connection alive even when I get calls?
I am suspecting that this might be a hardware problem but hope is the last thing that leaves us ;)

Seems to be a lot of bluetooth-problems for the S3 if you look at the search-results but my particular problem don't seem to be mentioned what I've seen.

Thanks in advance.
