That really sucks. It would be brutal to get that sorted. I’ve been lucky. I do recall once there was a botched update that reset all my custom settings on all of my devices. I was really choked but I had a old backup that restored it halfway. Reminds me to do another one now.

My huawei devices keeps reseting my launcher to theirs which is s really annoying but I think that is a Huawei thing.
