On at least Unihertz’s Atom L and Atom XL devices, there is a third-party background blocking application. It, combined with other default Android battery optimizations, can sneakily cause apps to not work as expected. Luckily, the steps to fix this are straightforward.
- Follow other vendors optimization steps, such as enabling ‘ignore optimizations,’ for your app.
- Go to Settings > Intelligent assistance > App blocker. Find your app, tap it. You can also disable the App blocker completely.
- Uncheck all settings, which include Boot blocker, Start blocker, Background blocker, and Background cleanup.
