The sound Quality is not so good.
It has h very noisy sound.
Becos of it screen size are so big that is not use very easy in hand.Accroding to Style And design the OppO F1s is not a such a cool gadget. When I Use Oppo F1s is produced lots of heat.It have a same apperence just like others smatsphone.
The phone has h very boring aPp.Feature of phone that is not good enough I just sometimes very fustrated with that mobile. The value of money this phone is very high other hand lots of smartphone hve same feature and sell with. Low price.
I think you should not use the Oppo F1s.
