Hi m_barber84, well I have the A20e back from Samsung Repair. They use a place called TMT in Stoke on Trent. I had no dialogue or explanation from them but the worksheet with the phone states 'replaced pba'. I understand that this means Printed Board Assembly, which I think is one of the basic components of the phone.
Having switched the phone on and charged it (they'd run the battery right down) and reloaded everything (they'd wiped it clean) I left it for a couple of hours and the wifi was connected and working. Then, surprise surprise!, the wifi disconnected again. I then left it overnight right next to the router and again it disconnected by morning. The only difference from before is that the wifi symbol seems to disappear completely from the home screen rather than staying there with an exclamation mark.
There clearly seems to be a defect in the Samsung A20e as it seems incompatible with the BT Homehub4. I will explain what's happened again to Samsung in a chat if I can get through to them and feel strong enough. I just wish Samsung would take ownership of these issues and accept their product is defective and needs to be replaced.
Good luck with whatever actions you take next!
