Thank you for contacting In-Flight Assistant for android support!
I am one of @epaga’s beta testers and I have looked into this matter for you.
I have added both of you to this post so you can both test these steps!
I can confirm that In-Flight Assistant works absolutely fine without any issues on my end.
I have the same version of the app anyone can download from the Play Store with all the add-ons purchased.
My testing environment:
Huawei Mate 20 Pro
Android 184.108.40.206 (with January 2019 security patch)
There are known issues with android itself, but it’s more related to manufacturers who are known to have aggressive background application management in their version of android.
One of them is Huawei. It seems now Samsung needs the same workaround as well!
This issue has nothing to do with In-flight Assistant as far as we know!
Solution or ‘What you need to do’ :
in the Settings menu, either under Battery or Apps, find App Launch.
The App Launch menu should have a list of installed apps. Find IFAssistant.
if you haven’t touched it previously, IFA should display Manage automatically under it, with a slider on its right. Please see image below.
tap on the slider, and from the 3 options make sure you set Run in background ON with the slider on its right.
press OK, exit Settings and launch IFA and IF according to the android guide.
I have checked it for you with an over 6 minutes flight and I have received the relevant callouts during the whole flight and experienced no disconnections after following the above steps.
The menu system in the Settings on Samsung devices could be slightly different, but you have the option to search in the menu using the search field located in the top of the Settings menu.
This App Launch setting has to be done every time you uninstall and reinstall IFA. If you don’t uninstall it, as far as I know, you don’t have to do these steps, not even after an app or android system update. It is wise to check the App Launch settings though every now and then to make sure IFA is still allowed to run in the background!
