I purchased a new iPhone se housing from eBay because mine was damaged. However my wifi only works when directly next to the router. Same with Bluetooth, it has a lot of static and is only clear when I hold my phone directly next to my Bluetooth headphones. I have tried two different wifi antennas now (a new one and the original) and it still doesn’t work like before. Please help!
Maybe the housing is defective or is poor quality and the antennas in the back of the phone and not reaching the towers.
