Qi stopped working?

I have a t-mobile G4 and have been using qi pretty much as soon as I received the phone back in the beginning of June. I have the AliExpress sticker and another from Amazon, one on the brown leather back and another on the red leather back. About a week ago I noticed my phone wasn't charging over night so I thought maybe I just didn't place it properly but I found it just totally stopped working. I have 2 TYLT chargers and 2 Nokia puck chargers I've tried and no luck. My wife has a G4 as well so I swapped backs with hers and they work just fine.

Any ideas on a fix or anyone else with the same issue? I tried doing a hard reset already thinking maybe something set it off but that didn't help. NFC is working fine thankfully.

Any helps appreciated! Thanks
