Enabling wifi while a game is running causes the Lenovo S939 to freeze or crash

When turning on the wifi connection on the device, the game either crashes on the device or it'll freeze for about 15 to 30 seconds.

Devices:
5231_S939 (ARM Mali-450 MP4; 4.4.2) - occurs on
2894_GalaxyNote2 (ARM Mali-400; 4.1.1) - does not occur
4022_Nexus5 (Adreno 330; 6.0) - does not occur
5065_iPhone5S (Apple A7; 9.2) - does not occur

1. Download project from: [Link Removed]
2. Launch or package onto Android device
3. Change the wifi settings while the game is still running

Result: The application will either freeze or crash depending on whether or not you're active within the game.
Expected: The internet connection connects back to wifi without any trouble.
