Your battery is probably expanding cause brighter spots on lcd due to pressure on lcd. You should immediately open phone and replace battery. You can get battery for around € 7- 10.

I just got the UMI Plus in italy; got it with Android 6, upgraded immediately to 7.0 and I am having a very bad experience.
When battery is at 50% and below, it discharges withing 2-3 minutes to 0% then shuts down!
Unfortunately it isnt battery calibration i think.
Can anyone help me? how can i resolve this problem? will i resolve this problem if i flash a previous rom (i have now V3.02_20170613) ?

Why do you want unlock bootloader?

i tried to flash rom with flashtool from windows and from macbook with terminal but when i connect the phone the flashing process doesn't start and it goes in recharge mode...so i think that is because of i didn't unlock the bootloader... isn't it? thank you for your help. So what i have to do to install a previous rom because it goes in recharge mode and flashing process doesn't start?

yes i've done all the things that are in guide but when i try to flash a prevoius rom with SPFT and connect phone turned off the process doesn't starts and phone starts to charge connected to pc (with windows) . I also tried with macbook using terminal and fastboot but to do this with fastboot i need to unlock bootloader and when i try to unlok it with terminal command it says to me that i have to press volume up to confirm and i press and press but nothings happen because volume up doesn't work in fastboot unloking mode.
