Unfortunately, some Android manufacturers implemented very strickt background policies, so that apps like one sec cannot do their job properly.
The good thing is, for most devices there’s a workaround to allow one sec to do its job:
Samsung
Open your phone’s Settings and go to → Apps → one sec → Battery
Make sure “Allow background activity” is enabled.
Then, go to “Optimize battery usage” → select to show “All” in the dropdown at the very top → search for one sec and make sure that the toggle is disabled.
Next, open Settings → Device Care → Battery → Power mode and select High Performance (or Optimized Performance).
- Go to your phone’s Settings → Battery and device care → Battery → Background usage limits → Never sleeping apps → add one sec to the list.
- Go to Settings → Battery → Battery optimization → All apps → one sec → Don’t optimize.
- Go to Settings → Apps, tap the menu icon (top right) and go to Special
- Go to Settings → Device Care → Battery → Power mode and select High Performance (or Optimized Performance).
- Disable Put unused apps to sleep and Auto-disable unused apps.
Huawei

On top of that, on some Huawei models you have to go to your phone’s Settings → All → Startup manager → enable for one sec.
Go to your phone’s Settings → Battery → App launch → Turn off “Manage all automatically”→ one sec → Make sure to ENABLE all toggles.
On top of that, on some Huawei models you have to go to your phone’s Settings → All → Startup manager → enable for one sec.
