Recent apps button

Recent Apps button doesn't work on my device. I think it's problem with kernel. On malaysian stock kernel all work correctly.

Blubberor · Jun 28, 2015

O know, Bluetooth is untested. Music works but no calls over Bluetooth.

Best and thanks..

ayamgoreng · Jun 28, 2015

I always thought SELINUX = permissive is advantage
since it's easier to install certain program (viper4a,etc)

Shafayat · Jun 29, 2015

does this have the audio call sound problem like resurrection remix? thanks.

dgjl · Jun 29, 2015

How's the screen? Any way to change display mode to 'basic'?

I have been used my ROM for two weeks as my daily driver.
I tested Wi-Fi/RIL (Calls, MMS, Mobile Data, LTE)/Camera/Video/Audio/GPS/NFC/... and no major problem except for "known issues".
Please try and test.

They are the same exynos based cpu but from different country

Beide known bugs nothing else with my phone running CM as well.
really very snappi!
Most important points is increase audio even more for phone and bluetooth working with phone - only works with music.

Best and thank,
Blubbert

miszko77 · Jun 29, 2015

Echo during call is not repaired. Major phone function is not working properly. It should be primary bug to be fixed.

cacahuttes · Jun 29, 2015

and bluetooth please? don't work for me!

It's a device related bug that affect some people not others.
Basically the only "fix" to it for the affected people right now is to use the stock Malaysian kernel (that Ozcan posted in his Rom thread from memory).
