I have been very happy with my Asus Zenfone 8 for several months. Everything changed after it automatically updated (OTA) to Android 12. It started restarting on its own every few days and I didn't found any pattern as to why it is happening. I'm not doing anything particular on my phone when it restarts. Sometimes I'm not even using it actively and when I take it in my hand, I see a request to enter my PIN, because it restarts when idle.
