Hello, this is my first post. MI5 have 32 Gb a week and this is my problem. I installed the two (the stable and developer) and back and menu buttons do not respond properly, and eventually stop working Xiaomi.eu latest rom. If I lock and unlock the screen back to work. I had to go back to the officer and now work properly. Not if there is a solution for this. As I have read in some forum it is because mi5 two types of panels mounted one is from LG which is what I have. Thank you.
