I got a refurb 512gb unit and the WiFi seems quite strange, on the same room as the router sometimes I have 4/5 bars of the signal that don’t make any sense considering the distance, and about the noises, the plastic that finishes the top part of the device, where charge port, volume buttons and the exhaust fan do a creaky noise if I press it as if something was broken or not fixed properly, has anyone here faced these issues? Is it enough for me to send it back?
