Hey im using a mobile phone of OPPO model number is F1 I am using this phone from last six months I like this phone very much because it has very good specifications first of all it has a 13MP rear camera and 8 MP selfie camera and a 3 GB ram phone with 16 GB inbuilt memory with 4G VoLTE support but there is a problem it is a hibrid phone it means if we put 2 sim cards we cannot put an memory card in that if I want to put memory card then I have to remove 1 sim card that is the main problem otherwise overall performance of the handset is very good service is good I have purchased this handset in 16000 rs its worth buying.
