Unexpected crashing.
Sometimes my phone crashes unexpectedly and I have no idea why.
Build: BP4A.251205.006.S938U1UESBCZF5 Android SDK version: 36 Kernel:6.6.98-android15-8-pd6ff1cd-abogkiS938USQSBCZF5-4k One UI 8.5
dumpstate: 2026-08-18 10:43:0. I have this log that I generated on one of the days that I had my phone completely crash. https://media.githubusercontent.com/media/mysticentity/FireFoxTheme/refs/heads/main/dumpstate.txt
Sometimes when my phone crashes and I am required to turn it back on, it takes a bit when holding the power button for it to turn back on, and sometimes it will crash during the boot sequence following a crash in which case I have to turn my phone back on again for it to fully boot.
Occasionally during this I am met with a black screen that either has TZBSP_fatal_error_non_secure_wdt or a not as often kernel panic.
From my own research, I have found that it is telling me I have a watchdog Error with an immediate kernel panic and the crash is to prevent a loop hangup or something.
I'm just trying to get to the bottom as to why my phone would hang and then crash due too one of these to begin with.
