Do not buy Oppo phone

My experience with this phone has been horrible. The phone freezes. If you listen to a whatsapp voicenote, ithe screen will be black as though it is switched off. It will take 3minutes to funtion normally again. I took it for repairs and it caback worse with speaker issues on top of the fact that it just randomlyswitch off after a video call or after listening to voice not. Even worse if you use Google maps. I received an Instagram video call and this phone froze and has had a black screenfor 48hrs now. People barely hear me when they call me. You would think it will be better if I put the call on load speaker 🔊 but it becomes worse. I can't use the phone. I have to take it in for repairs again.
