Not sure if anyone else had an issue but when I got the wireless charger for the Model 3, my phone would slide off when ever we hit a bump or accelerated quickly. I designed a quick little shelf/clamp to help keep the phone from sliding off, it is about 4mm tall and flat instead of rounded. If you have a 3d printer, you can find the piece here.
