Issue Details

I always keep the protection enabled. However, protection keeps disabling by itself anywhere between 8-16 hours.

Steps to reproduce:

1. Restart phone, confirm protection is enabled.
2. After 8-16 hours check the protection status.
3. It would be in disabled state.

I have excluded the app from battery optimization, "locked the app". But still protection keeps getting disabled. Also have a 10s watchdog timer that should potentially restart the app if it's gets terminated. Even that doesn't seem to fix the problem.

Expected Behavior

Protection should not get disabled until I manually disable it.

Actual Behavior

Protection keeps disabling by itself anywhere between 8-16 hours even with Watchdog with 10s duration enabled. This was happening across all devices used by my family (2 Samsung, 1 Asus, 1 OnePlus and 1 Realme tablet). But after installing the latest update, the issue persists only on OnePlus phone.

@shriganesh In order to troubleshoot this issue, we need to get your application logs.

Here's what we need you to do:

1. Enable debug logging:
   Settings -> General -> Advanced -> Logging level -> Debug.
2. Reproduce the problem, then remember the exact time when it happened.
3. Collect logs:
   Settings -> General -> Advanced -> Export logs and system info.
4. Send this file to qa@adguard.com:
   • include [android] keyword and 6020 in the subject of your email
   • specify the exact time when the issue occurred

Hi @maxikuzmin
I have enabled debug. After upgrading to latest version, it initially didn't stop on my other phones. But protection has stopped on other phones too. I've enabled debug on Oneplus and Samsung phones. I'll share the debug logs once it capture the issue reproduces itself.

Thank you,
Shri

[maxikuzmin]

@shriganesh any news?

[zamanh]

@maxikuzmin can we reopen #6026 please - seems like it still happened

[shriganesh]

@shriganesh any news?

This has been happening in 4 phones and 1 tablet. I've enabled debug on 2 phones but after enabling debug mode on these phones for over 5 days it hasn't stopped protection. While in the other 2 phones, protection has stopped at least 2-3 times in these 5 days.

I'm guessing enabling debug might somehow be preventing adguard from being killed.

Definitely happen very badly on HyperOS 3 Xiaomi 17. Despite allowing it to run in background.

[zamanmh1]

I tried using the latest nightly and still keeps closing prematurely whilst I use the phone.

[zamanmh1]

Reinstalled release version (unfortunately wipes out stats). To see if it helps.

[zamanmh1]

I have noticed this setting keeps getting flipped from Unrestricted to Optimized each time AG exits or protection restarts.

[zamanmh1]

Now AG exits prematurely as I use my mobile device! There seems to be something not right. Will enable debug logs and get some logs sent.
