Yesterday I update android version to 6.0 and until I make this update the signal of sim didn't work I try many times restart phone and showdown more than 2 hours and nothing happen still have problem
I try to replace sim to other phone sim work good
I try to exchange Sims 1,2 still have problem
I make factory reset 2 times and I get signal for 1 hour then I lost signal again in both Sims
Before I make this update my signal work good after this update I have big problem with signal
