Android 10 upgrade - Random reboots

@Alain_Guillet I advise you to use Docker containers, data and OS seperated and always a clean host :wink:

@AnotherElk Currently I have setup my own Nextcloud instance, hourly btrfs snapshots and daily off-site backup. The most important data is therefore backed-up.

All the app settings and configurations is what would take the most time. :see_no_evil:

Any hint on a non-Google backup solution for the apps on a Stock ROM without root permissions would be appreciated.

Thank you, would be great :+1:t2:

I opened and cleaned the device and tightened the screws yesterday.

Until now I hadn’t any reboots so far.

I’m glad you didn’t make a locked bootloader a requirement, because with an unlocked bootloader it is relatively easy …

https://community.e.foundation/t/backups-bootloader-root/15632/5?u=anotherelk

An unlocked bootloader means the phone should really be encrypted and a decryption password/PIN/pattern should be set, so a simple loss or theft of the phone would not expose your data.
That would still leave a risk of somebody snatching your phone temporarily, installing malicious stuff on it which would e.g. log and transmit your decryption input, then getting the phone back to you unnoticed to provide the desired input … so you would need to assess how likely it would be for someone to really target you this way or how many opportunities for this (unattended phone) you can see yourself giving up in your everyday life.

With a locked bootloader indeed Apps and their settings/data are a problem.
I would say a collection of App APKs (there are Apps to extract those, even for split APKs*) and screenshots of the settings pages of the Apps are a backup … nobody said it would be effortless :slight_smile: .

Well, it is indeed a requirement too.

Yes, this is how I do it actually for a phone migration, comparing the devices and set the appropriate options, but this takes time and settings may get forgotten.

I’m ok to put effort into this but the backup needs to be done automatically after the initial effort, so this is not really a solution for my problem.

I played a lot with CyanogenMod (ClockWorkMod) and later TWRP some years ago, it was fun and worked great to create images of the OS.

I even had my own F-Droid server/repo with APK copies from the Google Play Store (semi-automated updates) used on my devices, but now I’m tired of Apps requiring the SafetyNet approval or the “App installed from Google Play Store” requirement. Not to mention my short excurse of Aptoide and their APK uploader :wink:

Sure I could root the device, install may be Magisk to hide root to get those apps working again, but I just want to use the device as it is and workaround the non-root restrictions as good as possible to have the best possible Stock ROM experience (and may be one day even with a full backup) ^^

I did a factory reset this morning and haven’t had a reboot all day. So maybe it’s fixed?! :man_shrugging: I’ve still got an Android 10 system with build number 8901.3.A.0033 as recommended. So hopefully it’s fixed now.

So that lasted about a day then still a random reboot.

I’ve also removed the SD card because I had that setup as phone storage and it seemed to be causing all sorts of issues.

I’ll try tightening screws next.

I’ve been seeing a lot of reboots since updating too. They seem to happen when I’m stressing the system, flipping between lots of different apps etc but I haven’t found a pattern yet. At least the boot time seems improved following the update!

Yes, the boot time is very good now.

Had no reboots since 2 days now.

Just had a reboot while my phone was sitting in my pocket, so that disproves the theory about it being triggered by heavy use.

I’ve also had about one reboot a day ever since the Android 10 update. Until now it always happened while using the browser (Firefox), but today the phone had rebooted in my pocket.

As so many people are having this problem right after an update, it doesn’t sound like something related to loose hardware. If fairphone devs are reading this, I’d like to know if the root cause has already been found. If not, I can try to provide some help (e.g. system logs, testing) if you tell me where to look / what to do. I’m a dev myself, so using e.g. adb is not a problem.

It’d be interesting to know if the reboots persist after having now deintegrated the SD card.

Tightened the screws this morning (after having coffee, just to make sure :+1:).

Yet, I’ve had 3-4 reboots today, all of them with the phone just lying around in idle mode.
(The phone sometimes also doesn’t wake up when trying to unlock - from time to time this ends up with a reboot as well.)

Becoming a bit frustrated here :confused: (after having lived with an unstable FP2 for several years already…).

Hello,

A year ago, I oder 2 Fairpone 3.
One for using, one as spare part.
Since the Android 10 upgrade, the “using” FP3 restarts from self 1-6 times a day.
Set the FP3 as recommendet to factory defaults, afterwards “install” the APP’s from APP store.
The FP3 restarts from self 1-6 times a day.

OK.
Take this morning the “spare” FP3, upgrade it to Android 10.
“install” the APP’s from APP store. And the FP3 restarts from self until now 4 times.

I think there is a challenge by the new Android 10 on FP3 classic.

I think first, the “using” FP3 can have a hardware problem.
But the until now not used (stored in the originaly box) “spare” FP3 has the exact same trouble.

Well, I think I have to reactivate my “old” Sony until the trouble by FP are solved.

PS
as on call it is important to have a working (not self rebooting) phone

Adding to the conversation that I also have a Fairphone 3 which has been rebooting at random since the Android 10 update. Very unlikely to be hardware issue as it will occur even if the phone was lying still on the desk for more than an hour. No reboot troubles prior to this. Ive had software problems with the sound on the Fairphone 3 also.

Any word from the Devs on this?

I’ve had 3 reboots already this morning (including one while typing this message) so it looks unrelated to the SD card

I’m very sorry to hear that! Anyway, thanks for the feedback!

I have an FP3 with stock FPOS and a sizeable number of third party apps. No reboots with Android 9 and no reboots with Android 10.
