I rebooted my phone this morning and noticed an icon of an open lock & the word "Custom" on my boot screen... I have not rooted a phone in over 2 years and have been through several devices since then! It wont let me check for updates because of this. Is this happening to anyone else? What could've caused this?? I do not sideload apps and unknown sources is always off.
