Heating near the camera is normal cuz the CPU is next to them...screen is heated up due to excess memory usage, higher Brightness or wrong screen resolution
I even switched off fast charging. And i charge the phone only to 80%. I cant take it to a service centre bro because of lockdown. I am doing my online education through this phone. I am afraid that this issues will damage the device. Please help if you have solution🥺
Try using power save mode which decreases the cpu usage, use dark mode and lower Brightness, use Natural colour mode on display settings too...charge when the phone is down by 40 and stop around 85..
