Had no reboots for more than 2 months now after upgrading via OTA to 20180307-1950. Yesterday they suddenly came back and I had 2 reboots in only 2 days. I had the exact same situation once before.

Did you perfom a factory reset after the OTA update?

You ask that every time. My answer is always no.

I ask it every time for a reason..... 
If you update your phone and don't perform a factory reset, you can face an unexpected behaviour, as, for example, the came back of the reboot issue.

That's what you say. But do you have any prove that a factory reset is really necessary after every update? I doubt it. It's just your standard answer. And if you read different mobile phone forums, most of them say a factory reset is absolutely NOT necessary. Also most of the people here who had a problem and did a factory reset after that still had the same problem.

It reminds me of the people who recommend you to wipe your Windows installation and do a "reset" no matter what problems you have. Which also is total bullshit. If something in my house is not working I also do not break it down and build a new one.

No offend, it's just my experience.

I respect your experience, but i can tell that a factory reset solved many problems. One of them, that i remember clearly, was about the battery drain issue still present after the update wich was released to solve it.I know what i say.
Have you ever gave a phone to a repair center? the first thing the do, even if they have to replace the LCD display, is to reset your device to the factory state. Guess why

If the phone is rooted you can just delete the sound file located here..
/system/media
If you delete the start up and shut down animations aswell it just reverts to a stock android logo
 

Hi,
my phone also started to randomly reboot itself (day, night and while charging) but only after the flashing to OREO (with factory reset)

PLEASE refer to the Oreo "service and tech" subforum.

Ok, i have tried lately to update to the android 8.0 twice, with local update, it imitated the update process, but didn't update, i still have same version oof android 7.0 that I had. But after those attempts, it started to reboot at night, i noticed that it does that at the same time at night, and only once a night, seems like some timer in it. So, i have set in the option of automatic update, update only via wi-fi, and turned the wi-fi off for the night, and guess what, it did not crush and did not reboot...
