15 Pro Titanium Natural 256 for sale or exchange

My new phone in the quarter, I replaced its screen, it got damaged, I installed a screen for it only and updated the phone, now it's like this. Of course, first time the phone broke due to its screen, has anyone faced this issue before? This phone has no solution, so it's for sale or exchange for a 15 Pro Max willing. But strangely, after the update, my phone became like this. Very little usage, cycles 64, battery 100, why did this happen? I don't know.
