i'm not 100% sure if it's a common problem but i guess it is. and i don't have a solution for it so if anyone knows, thanks in advance. Phone App ALWAYS Switch to Landscape Mode After Each Reboot or Lock/Unlock on Both Automatic and Portrait Mode. steps to re-produce it: 1) select either automatic or portrait mode for phone app. 2) screen lock the phone. 3) stand the phone upright. 4) unlock the phone. 5) open phone app. result: phone app will start in portrait mode but will switch to landscape mode quickly. it will switch back to portrait mode after clicking any control on the screen. opening the phone app subsequently without locking/unlocking the screen will give the correct orientation.
