I recently installed the 4.1.2 Jelly bean rom on my Sony Xperia U. The rom i used was [ROM][UB][UNOFFICIAL] Jelly Bean 4.1.2 Stock Fw 6.2.A.1.100 FiNAL was this. I found this from one of the thread. Everything works fine except for the lag in calling and dialing a contact. I tried to post on that thread but i was not given permission as it was a development thread.
Don't be irritated with me guys, i do apologize for creating a new thread but i wanted help badly. Hope u understand.
Kindly guide me as i'm new.
