iphone 12 freezes on lock screen

I have an iPhone 12 and after updating to iOS 26, the lock screen sometimes freezes (something like 1 out of every 10 times I lock the phone, it freezes on the lock screen). The clock works, Face ID works, notifications appear, but the touch simply doesn't work. I have to hard reset the phone (volume up, volume down, and hold the power button) several times. Sometimes I need to reset it 5 times for it to start working again. I've already tried disabling Face ID, reducing transparency, deleting contacts, re-installing iOS using DFU mode, IPSW, and nothing works! I'm going crazy having to reset my phone all the time.

You need to have Apple perform diagnostics on your iPhone. It can be done in person at an Apple Retail Store or at an Apple Authorized Service Provider. You can also contact Apple Support and request remote diagnostics.
