Hi. In the UK, I bought a Redmi 7a last autumn. It'll still be under warranty if the problem is something I can take to them. I don't use it that much; the only apps I've installed are Firefox and BT Wi-Fi (from my ISP). Twice now I've had the same problem, maybe a couple of months apart. The last time I fixed it by resetting the phone, but obviously I want to avoid doing that over and over. The issue is: the alarm doesn't work in the morning, I unlock and look at the phone and the whole screen is flashing, I reboot and get a home screen with a big square area at the top saying "Loading" (see screenshot). I've tried the built in "find and fix issues" app, clearing cache, searching for viruses. Help appreciated.
