Hello, I have the ascend p7 l-10 on b616 full rooted.
I tried changing some lines in build.prop (I followed a guide found here on xda) but nothing happened.
Is there any solution?
I bought the case from ebay. Somewhere I read that something might be wrong with some aftermarket cases. Is this possible??
I've attached a photo showing the problem.
Thanks in advance.
