This issue was reported by a user who was having issues with their modulated shadows showing up in random spots on their mobile devices.
Their devices were a Samsung Galaxy Note 2 and a ASUS Zenfone 4. Both at Android 4.4.2. They then later tested on Android Version 5.0 with a Asus Zenfone 2 (ZE551ML) and the issue no longer occurred
I tested this on a Galaxy Note 2 with Android version 4.1.1 (Asset ID: 2894)
This issue also occurred in 4.10.4
