So I took it to the repair while the battery was about to die. Somehow, the battery just started working again (it kinda phased in and out of broken and not broken before dying at the time of posting) so they saw Magisk was installed. Fast Forward to the day I made the post. The phone finally died completely and wouldn’t charge no matter what, but I hadn’t uninstalled Magisk. Meaning I can’t unless its repaired. And if they repair it right now, I won’t have a chance to uninstall Magisk and will be forced to pay for it.
