Sorry for not being able to give you a solution, just warn you that there is one thing you should not do with this phone, as a preventive measure, it is to put it in a pocket where there is a risk of twisting or bending, in short, the front and back trouser pockets. Shirt or jacket pocket are the only acceptable places, if not, in the medium term, it is sure to fold, just like some of the first 4 inch phones and + of the years 72-73 like the Wiko Peax and King.
That said, when it is in one of my pockets, shirt or jacket, it never unlocks, but it is pockets where there is no pressure.
Pocket mode is not activated on mine, the other parameters are identical.
