I bought a 2020 Silverado Texas Edition in September 2020. I have also had the black screen issue AND the screen freezes randomly. Ive taken back to the dealership at least 5 times since September and no update seems to fix the problem. I’ve been told it could be a phone issue, but I’m in disagreement with that. I’ve used my phone on Bluetooth and CarPlay in other vehicles and NEVER had any issues. It’s a shame that I’ve spent so much money on a brand new vehicle and I can’t even use the features that comes in it. Sounds like GM needs to get it together end fix everybody’s issues.
