You update to 38R via OTA or flash?

If you want give it another chance then do a clean wipe and try again? 

1. china and international ,handwise , so close to similar...
2. price so closely similar
3. change phone more often than buy new sport shoe
4. backcover can *almost* change to cynogen mode on from internet sites like taobao
5. If want, sure want it soonest possible mah
6. ppl less know about this brand what more distinguish ur set if cn. or int.
7. so, is mostly, self satisfied for int only.
8. int is arguably riskier, many stop points. cn. u direct deal
9. warranty issue sure cn. deal locally ,arguably easier as well and possibly shorter coz the former need to send back to country of origin
10. get it fast, join the opo family fast, enjoy earlier i.e. ART/updates/Android L and learn earlier and become flasher lv999 also faster

now i know why people who updated to 38R via OTA keep getting problems like random reboots, flickering screen, etc.

haih... just realized upon flashing the true full rom.. many functions and features were missing on the OTA

zzzzzzzzzzzzzzzzz

and again. restoring was fast, backing up took longer time
