Ramy,
Please...be civil.
The very well known and respected soaring vendor that I purchased the Fusion from has been using a Fusion on his desktop and he cannot get the Fusion to be recognized by his Android phone. Apple phone has no problem. On his desktop there is no problem with blocked antennas. There is much more here than a blocked antenna problem. The solution is NOT to buy an Apple phone.

BTW, nice flights your have been having lately.
Usually, issues like this are related to using an older phone that only supports "classic" bluetooth when the device you're trying to connect to uses Bluetooth LE or Bluetooth SMART. I really don't know what Bluetooth standard the Flarm Fusion uses but I will make an educated guess and predict that the likelihood of the issue being with the phone instead of the Flarm is more likely than not. Android itself has supported Bluetooth LE & SMART since version 4.3 but the phone vendor still must have Bluetooth radio HW that supports the newer standards. I'd take a look at the Android phone and see how old it is. I personally have an Android phone that was released in Nov 2017 that doesn't work with LE or SMART (even though the phone specification says it IS compatible) so a phone doesn't have to be very old to have these issues.
