Model of the phone:Meizu MX4 Pro
Android version: Android4.4
OS: Flyme 4.5.7I(previous version: Flyme 4.5.7A)
When I received the phone fromthe seller there was Chinese firmware Flyme 4.5.7A andI reinstall it with the same international version Flyme 4.5.7I.

I have installed Android Device Manager anddecided to check its functionality. I set the password (it contained lettersand symbols) and locked the phone screen. After I locked the screen with letterpassword I have found that the phone can be unlocked only with digit password(see pic.1). I can't change thepassword in the Android Device Manager through my Google play account, because ADM doesn't allow to do that.
When I try to reset all the data, the phone starts to reboot andthen another issue appears. To put into effect the command from ADM and toerase the data from the phone, Flyme OS asks for the password to unlock thelocked screen. After the reboot I don’t see AndroidWelcome screen, but the screen mostly in Chinese language (see pic.2), that says something like “please enter thepassword to unlock the screen”. But I didn’t set any password to the screen exceptthe ADM password.
On Flyme screen I have the fullkeyboard opens and I can enter any symbols. I tried to enter the password fromADM, but that password contains 10 symbols and on Flyme screen I have anopportunity to enter only 4 symbols. I have tried to enter various symbolcombinations but nothing worked.

I have Flyme account and according to the instructionsI should have an opportunity to unlock my phone through the Flyme accountwebsite, but I can't do anything in my Flyme account beacuse there are no connected phones on it for some mystic reasons
