oppo r1001 joy phone problem
while i was changing my sim card some factory mode load screen started.it had menus in chineese language. i tried to power it off with power button but it would not work.finally i removed my battery and it turned off. now after i restarted my phone only one sim was working and only one sim features were available. its a dual sim phone and its not supporting two sims.
