Today I my phone started crashing when I tried to pull down the notification drawer. The whole screen would go dark for a brief moment while the system UI apparently restarted and I’d end up at the lock screen. Restarting the phone did not help. I pulled a logcat from the phone and found the following exception
java.lang.RuntimeException: Canvas: trying to draw too large(144480400bytes) bitmap.
Curiously, the crashes stopped when I closed all open apps.
