My iPhone 8 Plus camera quality seems very low at night and I can see dots on the screen
I purchased my phone in December 2019. my camera quality seems very low at night and I can see dots on the screen but my friends iPhone doesn't have issues like that with the camera. also it overheats like crazy when connected to wifi or when its just sitting out there and the heat is too much that I cant even hold the phone. battery capacity drops like crazy too for the past three months it dropped by 5% and I only charge the phone once a day and its also not until 100%. unexpected restarts occurs without notifications. And touch screen goes out of response sometimes and needs a restart to make it alright. the touch id sensor doesn't respond most of the times too.
when I contacted apple they asked me to restore the phone and update to IOS 13.4 and I did that too but the issues still occur. what should I do. as as I bought the ip8 plus very recent and its not even 4months. Should I ask for a replacement or a refund? Please reply me as soon as possible
