So since a few months ago, after being working for over three years, Hybrid Assistant now gives up after being connected successfully for less than 30 seconds. The middle bottom button turns red and shows "Disconnected". Closing and restarting the app will have reconnecting but again, that will last for less than 30 seconds (sometime just a few seconds). I unpaired and repaired my vLinker OBD2 adapter, didn't help. I thought I overloaded the system with thousands of recorded drives so I cleared the app's storage and cache. Didn't help either (sucks that I lost all my recorded drives). I uninstalled and reinstalled the app, same thing, still disconnecting. My phone is a Pixel 8 Pro at its latest Android version. So I took out an old Samsung Note 8 and installed Hybrid Assistant on it, paired it to my vLinker and... It stays connected. I went on a few minutes long drive and it worked perfectly, so it's not the adapter. So, there is something on my Pixel 8 Pro that kills the connection to the OBD2 adapter. I don't have any issue with other Bluetooth devices on that phone. Someone saw something like this before? Any solutions? Thanks. Edit: I tried my OBDLink LX and it does the same thing, so it's definitely not the adapter. I launched the OBDLink app and the dashboard stayed connected for several minutes, so it's not the communication either. What's left, the Hybrid Assistant App itself.
As it turns out, it was an Android 16 issue. Confirmed by the dev and fixed with Android 17 that was released yesterday. I tried it and yep, back in business
