Expected Behavior

The device should work normally without rebooting

Current Behavior

A few days ago, an annoying bug I encountered a couple of years ago recurred.

The problem causes my phone to suddenly and unexpectedly reboot when I'm on the move (in a car, on a motorcycle, or during other travels that involve changing cell towers).
Given the nature of the problem, I assume it occurs when the phone attempts to change cell towers, freezing and rebooting on its own. I also suspect that it may be something related to the device finding the default home Wi-Fi connection and in this regard I am testing the device by traveling with the Wi-Fi turned off to see if the spontaneous reboots persist or disappear.

I can't provide the log file because, as I've already explained, this is a random issue, and when it occurs, I obviously can't keep the phone connected to a computer to download the log file while travelling.

In other contexts (at home, at work, or somewhere that doesn't require travel), the device functions normally without rebooting.
This is a random issue and can't be reproduced using a predefined sequence of operations. It occurs independently of the user's will.

Possible Solution

No response

Steps to Reproduce

The problem is not reproducible as it occurs randomly and unexpectedly.

Confirmation

• I have read the directions at https://wiki.lineageos.org/how-to/bugreport

I'm sorry man, but without logs I have zero way to diagnose and fix the issue... one option you can try, is if you have another device handy, to setup a wifi hotspot and then use wireless adb (using an app like termux and install adb on it)
https://developer.android.com/tools/adb

and then on that spare device run the command:

adb logcat > /sdcard/Download/logcat.log

and it'll start logging to a file in your Download folder called logcat.log, and after your device randomly reboots, please attach that logcat.log here

I understand the need for a logcat is crucial; I'll try to get a second device and follow the procedure you mentioned.
In the meantime, I think I've narrowed down the issue further. From the tests I've done over the past two days traveling across a large area of ​​northwest Italy, I've found that with Wi-Fi turned off, the phone no longer reboots spontaneously, even when traveling through areas with poor coverage.
So, in my opinion, changing cell towers has nothing to do with it.
I've now tried deleting all the Wi-Fi connections stored on the phone and resetting only the home one, to see if the phone starts having problems again.
I'll update you as soon as I have any news.
