did you use the stock music apps play the music? i try before with 3rd party apps..the music album wont appear..after uninstall..it prompt out again..

I use both the default one and Google Play Music. Both also cannot.
U guys use what lock screen? The one that can swipe right and left for more shortcuts?

i used stock music player and able to get the fullscreen while locked.

maybe u need to do a factory reset...

Ok got it guys. The culprit was jays earphone control app. Uninstall it and issue solved.
Can now full screen album for both stock music player and Google Play Music.

learn another new thing so third party music apps and earphone control apps will interfere with screen album

R u all using GT-I9505?

after upgrade to kitkat i think got many bug.... main is email ... cannot check email...can downgrade back ???

See attachment below.

Wah serious or not?
so much prob?

I rather you use alternative email apps. The stock one is not the best to begin with.

do you direct flash from 4.3 or flash stock rom 4.4 first?

Did you turn on the AutoSYNC?

once upgrade to kit kat, unable to downgrade back to jellybean.. apps can uninstall update though..

try clear cache and data in application manager..and try see ok or not..

1) root 4.3 stock
2) flash latest CWM.
3) flash Wanamlite 4.4.2

Done !

I straight flash from 4.3 no need to flash stock first. If your phone can't boot up ( stuck at Samsung logo) , then only you flash Russian stock 4.4 first.

Since the KitKat update, I'm getting the "Your Internet connection is unstable" notification when using WiFi much more frequently.

seems not much different from 4.3 lei

Mind to know your CWM name and Version?

i think he using Philz's CWM Advance v 6.0.4.3

Downgrade is possible with Odin.
