Galaxy S9+ soft-reboots all the time

[Serpher]

After Android 10 update, my S9+ reboots all the time. At least once a day. It doesn't matter what I do or not, it just soft-reboots. I can browse Twitter, call someone. Phone can sit in my pocket or be on a charger doing nothing and it will soft-reboot nonetheless. 

Things I did so far:

1. Updated to A10 march update
2. Wiped cache
3. Factory reset
4. Safe mode

None of that helped. I've made logcat log but can't understand it well.

Assuming your phone isn't set up to reboot via settings - device care - press the 3 little dots in the top Rh corner - advanced - auto restart 

Then put the phone in Safe Mode which disables any downloaded apps and leaves the stock ones working and then see what happens.

If it stops then one or more of your downloaded apps maybe causing this.

Come out of Safe Mode and start deleting them one at a time until it stops.

If it continues in Safe Mode then seek support from a Samsung Experience Store  / Samsung Service Centre.

I wish you all the best with this situation.

As i wrote in my first post - I've tried Safe Mode. It's OS's fault, but don't know why.

Ok then please seek support from a Samsung Experience Store or Samsung Service Centre.
