Why Does The SynScan Pro App Disconnects Every 20 Minutes Using Android 10 On A Galaxy S10e With A SkyWatcher AZGTI Mount? (Answer: SynScan App Must Be Allowed To Run In The Background - Read On!)

I have SW AZGti mount. For the last few months I have run it from SkySafari 6 Pro on Motorola Droid Max with Android 4.4 with no issues. I would connect first to the mount using SynScan or Synscan Pro App, both works, and then connect to the SynScan within SkySafari.

On Christmas I got new phone Galaxy S10e with Android 10. With new phone I can still connect to the mount with SynScan and control it from SkySafari 6, but every 20 min SynScan disconnects from the mount. I can reconnect and it runs fine for another 20 min and drops connection again.

I have disabled smart battery management for SynScan and SkySafari and also turned on 'never put them to sleep' option. It did not help.

The only work around I was able to find so far is to bring the SynScan in front every 10 min. It seems that there is a hidden option which kicks background apps of WiFi every 20 min. Since it did not happen on my old phone it is either newer Android issue of Galaxy specific.

Posting it up to see if anyone found solution and also to make other people aware of the issue.

  I have had the same problem for as long as I've had Sky Safari and Synscan. It happens with different versions of Synscan, and under different Android versions. If I forget to bring Synscan to the foreground and I get a "disconnected" message from Sky Safari, when I then switch to Synscan I get the splash screen, so I assume it has actually terminated in background.  Like you, I've instructed Android not to kill it in background but it makes no difference.  I assume this is a problem with Synscan and nothing to do with Sky Safari.

  Thanks Keiron, I had already seen that post.

  I had already changed the setting to stop Android restricting Synscan's battery use when running in background - it makes no difference.

  The onward link to the CloudyNights forum doesn't really add anything. The settings screenshots that were included by one respondent are actually specific to Huawei phones and not stock Android function, so I don't have them on my phone.
