Unable to find backup file, attempt

Debuglog: https://debuglogs.org/android/6.21.3/01177a09899b85a8e75fd79b7194592f0f3adbcfef9b98ae995db6e8b7552c31 My mother's backup still doesn't work. Signal also attempts to write to non-existent external storage. Perhaps anywhere can Help my.

Backup failed Cellphone: Samsung A53 Android: 12,13 Signal 6.21.3 I do not understand why Signal do this. So it is not correctly recognized that no external memory is available and with external memory it works too not.

[Paulchen232]

My mother can`t send the neu debuglog as http. Debuglog

[Paulchen232]

in the debug log he does not find so many stickers.

First of all I transferred the account to a Nokia G22. The backup then worked there. There were some illegibility in the backup which I corrected with signalbackup-tools. I was able to export the chats as html. But back on the Samsung A53, the backup still didn't work.

[clark-signal]

So when you transfered to the Nokia G22 you hit some issues as well that you had to fix with signalbackup-tools? Do you remember what the issues were?

[Paulchen232]

Oh, I think I didn't fix anything. Since the backup works on the Nokia G22, the use of "signal backup-tools" was nonsenns. The inbound and outbound backups were the same. On Wednesday I will transfer the account again from the Samsung A53 to my Nokia G22 and then uninstall and install Signal on the Samsung A53. I don't think I've done that before. I'm curious if the backup on the Samsung works again when I transfer the account back.

[Paulchen232]

Backup on Samsung A53 futurmore not work. @clark-signal What android.calling.telecomModelBlockList in the debuglog means? Debuglog: In the Sysinfo is the Model: SM-S536B And "android.calling.telecomModelBlockList" is ..., SM-A530* What make this? My mother thinks that on 02/02/2023 the backup worked once. After a backup has been restored.

[Paulchen232]

@clark-signal I hope you can soon my help.

[cody-signal]

Have you tried selecting a different location to store the backup? It usually works best to create a new folder than use an existing one. For example, don't use "Downloads" or other system controlled folders.

android.calling.telecomModelBlockList is completely unrelated and is about calling.

[Paulchen232]

Yes I did that but it didn't help.

android.calling.telecomModelBlockList is completely unrelated and is about calling.

[Paulchen232]

Ok, I was thinking it might have something to do with the problem as the phone model is so similar.

[clauz9]

I see you reopened the issue, does it still happen with the most recent version of signal ?

[Paulchen232]

The close was an error. The backup works not.

[clauz9]

Can you open "App info" for signal and let me know what permissions you have allowed for the app, and also check in the "storage" section to see if you have "External storage" permitted

You can enter "app info" by long tapping on the signal in on, and then tapping on the small "information" icon

I have also do this: :\Program Files (x86)\Minimal ADB and Fastboot>adb shell appops get org.thoughtcrime.securesms Uid mode: COARSE_LOCATION: foreground FINE_LOCATION: foreground READ_CALENDAR: ignore WRITE_CALENDAR: ignore CALL_PHONE: ignore READ_SMS: ignore RECEIVE_SMS: ignore RECEIVE_MMS: ignore SEND_SMS: ignore CAMERA: ignore RECORD_AUDIO: ignore READ_EXTERNAL_STORAGE: ignore GET_ACCOUNTS: ignore READ_MEDIA_AUDIO: ignore READ_MEDIA_VIDEO: ignore READ_MEDIA_IMAGES: ignore LEGACY_STORAGE: ignore COARSE_LOCATION: allow; rejectTime=+10m2s798ms ago FINE_LOCATION: allow; time=+22m28s686ms ago; rejectTime=+10m2s798ms ago READ_CONTACTS: allow; time=+1h21m59s999ms ago WRITE_CONTACTS: allow; time=+1d4h51m54s635ms ago WRITE_SMS: ignore; rejectTime=+1d5h0m6s660ms ago SYSTEM_ALERT_WINDOW: default; rejectTime=+4h32m51s116ms ago WRITE_CLIPBOARD: allow; time=+1d4h49m47s475ms ago WAKE_LOCK: allow; time=+10m2s174ms ago; duration=+395ms READ_PHONE_NUMBERS: allow; time=+1d5h0m6s660ms ago RUN_ANY_IN_BACKGROUND: allow START_FOREGROUND: allow; time=+7m35s714ms ago (running) ACCESS_RESTRICTED_SETTINGS: allow; time=+1d3h43m7s68ms ago

And I do READ_EXTERNAL_STORAGE to allow. I think the problem Comes from a Huawei P9 Lite with internal memory on SD card. It was adopted with the Smart Switch app. On 29./30. I dry more: account to another Cellphone, new install Signal, backup test with neu account.

Well here's what I have...

The only thing that I can see that might make a difference is the MANAGE_EXTERNAL_STORAGE permission..

so since you seem comfortable using ADB, can you try

adb shell appops set --uid org.thoughtcrime.securesms MANAGE_EXTERNAL_STORAGE allow

And see if that fixes anything 🤔

When you run the ADB command make sure, there's only one phone connected to the PC, otherwise you need to specify which device to run the command on.

[Paulchen232]

Ok, I dry this later. I say If anything fixes.

[Paulchen232]

I have let MANAGE_EXTERNAL_STORAGE set to allow. That probably means all files access. Backup not working. I'll try again something on the 29th/30th.

Read this https://github.com/signalapp/Signal-Android/issues/12915#issuecomment-1624078250

[Paulchen232]

One more thing: I've seen that in the diagnostic log this often occurs with different stickers: java.io.FileNotFoundException: /data/user/0/org.thoughtcrime.securesms/app_stickers/sticker... Do you know how this is possible?

With another mobile phone where everything works, it is not in the "All files access" list either.

[clauz9]

Signal is not there, but "external storage" should be, have you looked at the screenshot ?

[Paulchen232]

Very very nice, now I have anderstand what to do. I see external storage with System-Apps. External storage call in German: externer Speicher. It is now on and the Backup work! I have explane it my mother with Telegram because shy must do it.

Many thanks!

[clauz9]

You're welcome, and I hope you mom figures it out... 👍

[Paulchen232]

The message of success came from my mother! 🙂
