[Closed] Texture does not wrap on Android ES2
We are encountering a problem in UE 4.12 on Android ES2 where textures do not wrap correctly, instead acting as if they're clamped. This has been tested on two Nexus 6Ps running Android N, a Samsung Galaxy S7 running Android 6.0.1, and a Samsung Galaxy Note 4 running Android 5.1.1. The Samsung devices are the Snapdragon equipped American versions.
This only occurs on the actual devices, appearing normally when previewed with the Android ES2 rendering level in the editor. This seems to happen regardless of texture dimensions, compression settings, mipmap settings, or power of two mode. When run with ES3.1, the problem does not occur.
On Windows, the 64x64 texture tiles just fine, even when set to the ES2 preview level.
On Android ES2, the same texture behaves as though it is clamped, even though wrapping is selected in the texture settings.
Assuming this isn't intended behavior, is there any way to work around this? Using ES3.1 isn't an option for us right now, unfortunately.

What are the UV ranges? This could be a too high a repeat rate (6 bits of precision used just for integer if x64). And make sure you don't go too far from the origin (0,0) as this will also lower the bits for fraction. Try turning on "Use Full Precision" in the Mobile section on the material and see if it helps.
