My Cousin is used the OPPO F1s, he was hopping great phone OPPO F1s when he is switching from Samsung but this phone and company has not impressed to him a lot. Over all design wise phone looks good but the hardware and software part does not match Samsung or even a stock android based phone.
We are talking about Android N 7.1 now a days and this phone is with Android Lollipop 5.1(two ages back to android). And the worst part is, there are no hopes for future updates according to the official sites.
Another drawback is you cannot use a basic function of Android i.e. Moving apps to SD card. Then whats the use of memory card option? Just for photos and videos? That’s not fair.
Theme engine is also on a very basic level. Not much to offer for customization.
Coming towards good part:
Selfie Camera is as good as promised. Really amazing
Design is very sleek and attractive
UI is pretty simple
