Google Maps shows constantly rotating direction despite other compass apps working correctly

Google Maps reports rotating direction (0.5 rotations / minute) with stationary phone. The compass is calibrated and works correctly in compass-specific apps. https://www.youtube.com/watch?v=x6uOI5g8xbc **Steps to replicate:** After booting into Safe Mode and calibrating the compass via rapid figure-8's (or slow, or rotations on table), the direction in Google Maps slowly rotates. EDIT: I did a factory reset and, before logging in, Google Maps still has this error. I think it may be a hardware bug at this point. **Apps affected:** - Google Maps (Safe Mode and normal mode) - GPS Status (only available in normal mode) **Apps not affected:** - "Compass" (orange circle logo) - Sensors Multitool (shows correct magnetometer readings for X, Y, and Z. Confirms correct calibration) https://goo.gl/photos/SavNsaY2PyNPa17G8 **Troubleshooting steps I've tried:** - Calibrating compass - Rebooting in Safe Mode - Disabling/re-enabling Google Maps (includes data/cache deletion) **Specs:** - Nexus 5X - Android 6.0.1 - Google Maps 9.34.1
