Some Android devices can be particularly persistent in trying to shut down background tasks to save battery. If you are the type of user to start your recording at a trail head and simple store away your device until it’s done, HiiKER will be trying to run in the background of your device while it’s idle. This means the app is a prime target for the Android OS to target when attempting to optimise battery life.
You can try a few things that will give you the best chance of consistent and sustained recordings on HiiKER.
First of all, make sure you power saver mode is off.
Secondly, you can set the HiiKER app to be “unrestricted” on your device when it comes to battery optimisation settings. Learn about battery optimisation settings here
