Repeated crashes/app freezes after unlocking the screen during a ride #21

Closed cstuder closed 3 years ago

cstuder commented 5 years ago

Multiple times I had the app freeze or crash on me.

(iPhone 6, iOS 12.4.1)

Scenario

  1. Start the app, start tracking.
  2. Locking the phone.
  3. Ride
  4. Stop, unlock the phone.

The app is unresponsive, showing the correct position, but not reacting to button presses.

Most time it's frozen and needs to be killed in the multistasking screen. The ride is not saved in that case.

Recently it crashed on me at that moment, I've attached the crash log to the issue.

BTW: I already tried deleting the app and re-installing it.

This might be related to low available memory or the calculation necessary when terminating a ride took too long:

We will try to add some debug code or a temptative fix in the next version
