[Closed] Terrain texture on Nexus 7 is pixelated which is ugly.

I have a terrain (about 2600*2600) with a texture (mipmap on, 4096, rgb 8bit). When I build the apk, and install it on my Nexus 7, the terrain texture is all pixelated and ugly. I have changed the tileset to 1 (both X and Y) but no luck.
Any solutions?

oh and Unity Answers wont let me attach/crop the pic. The pic overlays on top of the accept button…

Tegra 2 was the cause. Still here tho…
