Microphone not working.
Tested in hardware diagnose tool, and just heard a long "buzz" after recording. Due to this, I can hear my friends voice but they can't hear me, makes the phone unusable.
Worse Mobile ever heating ,earpiece and mike problem is quite common dont invest a single rupee on this blady phone
Won't connect to T-Mobile Data. I sat on the phone with T-Mobile for about 45 minutes and we never got the phone to connect with data. I'm roaming in China and I confirmed with a local sim card that the phone works on the local network. I have a Sony E4 that worked with the same SIM cards on the same network. I don't know if the phone will work when I get back to the USA on the T-Mobile network. I'm hoping there will some update tot he OS that the phone will start to work in China.

But am using z1s rear scratch guard. It is perfectly matching. Try and enjoy naked device., if you use a case, then it will decrease the sexy design. Good luck
Got solution for app lock for updated device.
Go to settings ----- security ----- apps with usage access ----- then turn ON your app lock...
If it didn't work for you, then uninstall your app and try a different app.
Am using applock developed by do-mobile.
Otherwise no issues with my mobile. After update, heating issues are considerably less.
