Hi,

could you describe a bit more in detail what are you doing and what kind of phone you use?

The problem you described looks a lot like a battery optimization problem.  
You can have a look at this page:

> **[Don’t kill my app!](https://dontkillmyapp.com/)**
>
> Hey Android vendors, don’t kill my app!

there are hints on how to prevent battery optimizations based on your brand and phone.

Does it make sense?
