My phone is a Huawei P8 Lite ALE-L21 (Running Android 6.0). An hour ago I was testing if the Android Device Manager worked for the phone by locking it and it did. Thing is when I want to unlock my phone it doesn't let me to.

The unlock screen has a number pad with 1,2,3,4,5,6,7,8,9 and 0. There is a delete button and an Emergency Call button but there is nowhere a submit button. I cannot submit the unlock code when I type it. It says 'Your unlock password is required after a restart'. When I restart the phone it displays 'Locked by Android Device Manager' and gives an option to go to the Emergency Call screen or to input the unlock password.

I cant take a screenshot because well my phone is locked and I cant access anything except the unlock code input.

I've tried recovery via ADB but that's not an option since my glorious phone decided to unauthorized my computer.


Fixed it by restarting my phone a couple of times and inputting the first password I've set via the Android Device Manager (because I've locked it multiple times after that to attempt to 'change' the unlock password).

  • Mark this as answer (Well, after two days, you know the drill) And Welcome To Android SE! Android Device Manager is always just a "little" bit buggy - It can work to your advantage though. Remember ADM can only change the password once, and it should be enabled as a device admin.. – Dan Brown Oct 19 '16 at 21:37
  • @DanBrown Thanks. I've noticed that with Android Device Manager, haha. Ill mark it as an answer when It allows me to (in 18h). – Dragg Oct 20 '16 at 21:57
