Freezing and rebooting

I’m running Android 15.01 Emerald. The past few days my phone has been freezing and rebooting. Some of my apps have also disappeared. Anyone have any ideas on what is causing this to happen? I’ve scanned my phone and there are no viruses or malware. Thanks!

Usually when my own Teracube reboots, it’s due to running an intensive sdcard process like uninstalling or removing the data from a 20+ gig game. When that happens, the sdcard will often fail to load on that reboot, causing my launcher to remove the icons from the home screen. While manually rebooting will properly load the sdcard, if your chosen launcher removes ‘missing’ apps instead of leaving the stubs, the icons won’t come back even after the sdcard is properly loaded. In my case, I simply export backups of my homescreen settings and reload them after the sdcard is fully loaded, but YMMV.
If you don’t have an sdcard in your phone, it might still be worth checking available storage when the phone gets slow. If storage is getting low before it reboots, it could be that one of your apps’ cache is filling up your available space and it gets cleared on a reboot.
