anti aliasing doesnt work on android

Hello. i am making a project for android. my test device has mali 400 gpu. it seems that i cannot make anti aliasing to work at all. things i have tried: r.mobilecontentscalefactor=1;r.postprocessaaquality=6(for fxaa and temporal); r.mobilemsaa=1(2 or above crashes the app at startup); used device manager to implement these. things look ok in editor but not in device. i can tell that setting temporal as the aa method changes the look(everything looks muddy/watery) but the edges are still there. and fxaa/msaa doesnt seem to do anything.
