I have used Oppo f3 mobile phone for about 4 weeks and I wondered why peoples are mad about this phone. This phone has so many cons. The most important is, this phone is over priced at these specifications.
Yes camera is wonderful but is camera everything for a mobile user? If your answer is yes then I will suggest you to just add 2000 rs more and buy a DSLR.
Let me talk about some of its cons.
Oppo f3 is running on MediaTek processor which is a cheapest brand in mobile markets and its processors are found in almost every low budget mobile phones. Even the low budget mobile phones of many companies like Xiaomi have Qualcomm processors.
Oppo f3 have just 1.5 GHz clock speed in its processor which is again very less. Even the budget phones today have clock speed more than 2.0 GHz.
It has IPS LCD display and not an AMOLED display. Its price is enough high, it must had to come with an AMOLED display.
Design is very common, resolutions are not much good, pixel density is just 441 ppi which you can easily find in budget smartphones nowadays.
So overall this phone is over priced according to its specifications. I request you not to become a fool just because of their advertisements. Always search for in depth specifications and reviews of every product you buy.
