Hello: Greetings from Egypt i am a big fan of you (Xda) and i hope to find a solution to my problem here as usual my phone as i said in title is Gt- s7262 android 4.2.2 and i wanted to install apps min android needed is 4.4.0 so i flashed a new rom lollipop android 5.0.1 and thanks God it works but the problem is all apps which require android more than 4.2.2 still don't work (install) with me
