Chinese smart phone oppo f3 is selfie phone. Except that it’s over budget smart phone for its spec. Data usage warning is also not good daily Waring restricted 5000mb. Network signal problem. I am using jio and bsnl only one preferred network available for dual sim. Processor is also not so good . Smart phone battery is also not so good . Fingerprint scanner is good it look slim thinner charging is good. Sound also good color os eui is ok One word about oppo f3 smartphone is front selfie smartphone. Little over cost
