I bought this used device like a month ago and for some days my phone has been randomly rebooting in every 15-30 minutes of usage.
I've tried following things:
1.Other ROMs( Lineage, Xiaomi.eu etc.)
2.Fastboot clean flash and lock.
These haven't solved my problem.
So I tried to save a log just before reboot.

The log contains a reoccurring error which says:

06-19 01:00:30.240 E/subsystem_ramdump(15079): Directory /sdcard/ramdump does not exist
06-19 01:00:30.240 E/subsystem_ramdump(15079): Unable to create /sdcard/ramdump
06-19 01:00:30.240 E/subsystem_ramdump(15079): Failed to initialize ramdump


and some other error is which is less consistent :

06-19 01:00:28.225 E/GpuMonitor(15060): fital error, can not mkdir:/sdcard/MIUI/debug_log/common, errno:13

and :

06-19 01:00:25.573 E/AudioFlinger(788): open /proc/1583/cmdline error




Is it a non fixable Hardware problem or are there any work around for this?
