Turns turned constantly from

The mobile phone has been switched off 2x in the few days since it is in operation, independently. The Accu was at about 40% and suddenly the phone goes out. Then stick it to the wall socket, is 0%. Very strange. Furthermore there is no indication that you have received a message or a missed call. You always have to activate the phone to see this. Corresponding Apps for from the PlayStore, I've tried. The mobile phone is still nothing. Seems this feature probably not support. The camera is absolute rubbish because my Galaxy Ace made better pictures. The "flash" is not worth to be called a flash.
Well, what it can: Making calls, texting can be. Then the fun is listening but also on almost.
Oh, whoever is going to pick this phone:
At the start of Accudeckel must be solved because the Accu has an adhesive strip on the contacts. Otherwise you can not starten.Vorsicht the phone with the Accudeckel. The is made of plastic and of my feeling ago, could the wear out quickly.

Addendum: After every Android system update the phone sorts the apps again "in the beginning". I put my most frequently used apps on the main screen. Now, after 2 System updates within a month I had to re-order every time the Apps.
