I let my sister take my phone apart, and when I got it back after she was done. My phone would barely ever reach any wifi's after I got it back, I just want to know if she didn't put anything back where it was suppose to be or what is it
It's possible that your sister may have accidentally misplaced some components or connectors while disassembling and reassembling the phone. This could be causing the issue with your phone's Wi-Fi connectivity. I would suggest checking if all the internal connectors are properly seated and connected. If the problem persists, it may be necessary to consult a professional technician or contact TCL for further assistance with repairing your TCL phone.
