Bug Report on Zenfone 2 ZE551ML Marshmallow 6.0.1

As U seen on Image My Storage Reserve is 16gb?? what Happened? and Some Wrong Codes on the top..

I updated my zenphone 2 ze551ml to marshmallow from asus official website since there was no ota update flashed on my phone, after updating i am noticing there is a bug,during call when i place my phone to my ear screen goes off thats normal but when i take my phone away from my ear to hung up the call,screen does not light up, so i cant hung up the phone if i cant see anything,i noticed many user of ze551ml complaning about this who upgraded their phone to marshmallow from asus official website.please provide any update to fix this issue,its really annoying.</span>

Recent screen on active app doesnt appear

I m facing frequent app crash after 6.0.1 update so i reverted back to Android 5.0 & now its ok

I'm loving 6.0.1 after manual update but minimum screen brightness is much higher than in 5.0 .  Hoping to fix brightness scale to achieve dimmer screen.

I am getting lots of crashes / freezing after marshmallow update. I have tried factory reset and wipe partition cache,  but freezing  continues. Asus Zenfone 2 ze551ml. Is anyone else having same problems. Asus please solve the problem through update.

hi. i m here just to know if these marshmallow bugs (sensor problems, etc.) are still active and if it is safe to update now..

My proximity sensor is not working 

Screen flickering after marshmallow update from asus ota 

Anyone know how to fix the senzor problem? ...
