The little problem ( maybe not problem) of the phone is, first firmware version I used first time, it was v.2.7.
Inside Settings, More Settings, Assistant, Switch Access couldn't be switch on ( also happened if I installed Anti Virus, the option in assistant to let anti virus app work ultimately couldn't switch on) . This problem I found, ficed afrer updated my Vivo V5 firmware OTA to version v.2.9.1.
Yes, overall is good. I just think Facebook app running in Vivo V5 doesn't perform very well, sometimes when reading or writing comments, the Facebook app act go back itself and for anti virus app, the anti virus won't run in background 100% . Other brand if I still remember when I installed anti virus app, in runs in background better than Vivo V5. Maybe it is caused by the MediaTek processor that can't perform as level as Snapdragon or something else maybe.
