Weird graphics glitches on certain Android devices. Any tips?

Hi there.
A customer recently got in touch with us regarding some weird graphics glitches in our game, Tsuro.
He is using a HUAWEI P9 Plus, which seems to have black artifacts on screen:

Has anyone else seen this anomaly?
(FYI this project was made in Unity 4)

Thanks in advance for your help!

Fixed it by turning of Multi-threaded Rendering. PUM! (Thanks to ArenMook over at the nGUI forums for the fix!)
