Samsung galaxy tab A7 / Tacx flow smart issues


I have recently bought a Samsung galaxy tab A7, and having connection issues to zwift / tacx flow smart trainer.

I can initially connect no problem, but the moment I start pedaling, the connection fails, so no data, no controlled resistance.

Checks so far:

  1. Zwift can receive power/cadence data from my stages power meter.
  2. Tacx training app can receive power/cadence data from flow smart. Also controls resistance.
  3. Run zwift from phone (Samsung galaxy S10). Works without fault.

So the issue only occurs when zwift is run on the Tab A7 and the Flow smart.


Hi, the Zwift app needs permission to use location on your tablet but not only that, you must pick “only when the app is running” and not “always.”

This may resolve the issue.

Yes I had seen that elsewhere, forgot to write that in my troubleshooting synopsis. So I have checked that and the issue persists. It’s the moment I start pedaling, so presumably when data is transmitted.

Just make sure there’s nothing else with BT enabled nearby that could be grabbing the signal. Terminate all other apps bar Zwift.
