Recently I purchased Oppo f1s smartphone from oppo authorised shop but now I think I have done biggest mistake after purchasing this phone.No doubt camera quality is good but the phone has heating problem if I use this phone for continously 1 or 2 hour. Sound is also not so good as compare to other low cost smartphones. Fingerprint sensor speed is slow as mentioned in manual. I dnt recommend this phone to anyone becausw its totally wastage of money. Guyz trust me dnt ever buy oppo phones because in oppo phone heating problem is common. After sales service of oppo is also not so good. So plz buy other smartphone not oppo.
