It really pains me to do this, but I have to switch. My Samsung S21 has given me issues for the past 2 years that I’ve had it, and the issue being that it keeps not being able to read my sim card after an update, and I go essentially phone-less for three days until Samsung updates again and “fixes the problem”, only for it to keep happening. It’s happened 5 times now, and I just can’t keep dealing with it. There’s no customer support, I can’t just go to a Samsung store and have it fixed. I really love my phone, but it needs to work as a phone, and it simply just doesn’t.
Not a Samsung problem, however enjoy your jump to the other side. Both have their positives and negatives.
