Several people have reported problems with Morpheuz charts and config page crashing the Pebble Time app on Nexus phones. The problem has been raised with Pebble and they have done some investigation and traced it to a native crash in the Android Web View (Chromium). Further they have added that it should never crash natively whatever we [Pebble] (or third parties such as yourself [Morpheuz]) do. Pebble have suggested raising a ticket with the Chromium project for investigation. This has now been done - see Issue 588873
It would be useful to give them and us some more information to work with. If you have a Nexus phone that gives problems, would you be kind and add a comment here on this blog post, or better add to Issue 588873. Include the phone, Android version, Pebble version and Pebble model.
Hopefully there will be a fix for this problem soon.
