I had a great session yesterday at my usual spot on a sunny day, but unfortunately the app failed to record it. The only portion that was saved is from when I was walking around preparing to get into the water.
My phone was in the same pocket and in the same orientation as it has been for the previous 64 sessions that the app recorded successfully.
I also noticed that the recorded portion shows a data quality rating of very poor. Every previous session has shown excellent data quality, so this is unusual. One thing that may be relevant is that I updated the app just before getting into the water.
If I send you the session file, would you be able to determine whether the remaining 4.5 hours were never recorded, or if the data might still be recoverable?
Could you send the original session file to support@sunbits.de? We’ll take a closer look.
A few questions that would help narrow this down:
Do you know which version you updated from (e.g. 2.0.21 to 2.0.22, or from an earlier version)?
Which phone and Android version are you using?
Which pocket and phone orientation do you normally use for recording?
Was there any change to your phone (e.g. an OS update) between your last successful session and yesterday’s?
Also, if you check the speed graph in the app — does it show data spanning the full ~4.5 hours? If so, it looks like recording did continue the whole time, just with poor GPS quality, rather than stopping early.
Do you know which version you updated from (e.g. 2.0.21 to 2.0.22, or from an earlier version)?
I update it as soon as it requests an update. I’m assuming it updated from 2.0.21
Which phone and Android version are you using? Samsung S26 ultra
Which pocket and phone orientation do you normally use for recording? front pocket of WIP wing impact vest. The screen is facing me, the phone is on its side. It’s like that since the beginning.
Was there any change to your phone (e.g. an OS update) between your last successful session and yesterday’s? There was an OS update last this past Wednesday.
Also, if you check the speed graph in the app — does it show data spanning the full ~4.5 hours? If so, it looks like recording did continue the whole time, just with poor GPS quality, rather than stopping early.
Data shows only for 16 minutes. When i took back the phone from my pocket at the end of the session, I noticed the time recorded on the actual recording screen was showing 4h34m. Then i hit stop, then i noted the recording failed.
The start looks fine, but the values become inconsistent partway through, which also explains the very poor data quality rating.
The pattern points to a GPS chip issue rather than reception: with weak signal you’d normally see accuracy fluctuate and gradually degrade. Here it’s the opposite — constant, unchanging, extremely poor accuracy (400-1000m) alongside an extremely high satellite count (62), with speed/course locked at 0. That combination doesn’t match a reception problem.
Because of that, there’s nothing we can fix on our end — without at least some usable raw GPS data, the session can’t be recovered or repaired. I’m sorry for you .
One thing you can try: power off the phone completely, wait 30 seconds, then turn it back on. Record a short session outdoors — a walk or a car ride, anything with open sky — and check if GPS looks normal. If it does, repeat the test again later. If it stays fine, the GPS chip likely just needed a reset. If it fails again on the first try, we’ll need to dig further to isolate where the problem is — though if it does turn out to be the chip itself, there won’t be a fix available from our end.
