Most of the issues exist during a phone call, and still occur even when I have full bars of LTE service.
For one, speakerphone volume is pitiful. With the volume maxed, I can still barely hear people speak. Non-speakerphone volume is fine.
Secondly, the facial sensor does not seem to function at all. When I end a call, or pull the phone away from my face mid-call, the screen stays black and I have to double-tap the screen to turn it back on.
Thirdly, I get this weird "tapping" noise through the earpiece (not the speaker) of the phone when I'm on a call. It is definitely a sound that is on the phone, although I havent been able to find the file for it...it's almost like the sound the OTA makes when you tap-on or tap-off, or like a bubble popping (anyone know the Facebook Messenger notification sound? Very similar). I havent been able to pinpoint what causes the sound to play...no combination of moving the phone around or pulling it away from/putting it back towards my face prompts it or makes it stop...it just happens. It is not constant, but over the course of a 30 minute phone call, I will hear it at least a dozen times. It usually plays two successive sounds. People I'm talking to do not hear it...only me.
Are these just issues we have to live with? At first I thought it was CM11, but after getting the same exact issues with AOKP...I'm wondering what the deal is?
