our game is 500MB max reduction in size I could do by reducing the texture size, and lots of other tweaks, still, it’s loading for ages. when launching the game, the sounds are playing properly but the graphics are loading forever.
please give me some suggestions how I can solve this.
thank you!
Unreal is not for mobiles. Unless yes you cut textures down, create materials from tillable textures not skinned meshes. etc,
But even then just engine is around 100mb (was in 4.2 last i checked that).
Better go godot or zomg unity for that.

I was thinking the same after all, but because I have worked so much on my project I sticked on UE 
Most of size can be cut from textures:
- no skinned meshes (past that player character)
- all textures tillable
- single texture per material - diffuse/color
- normal maps specular etc done from tillable NOISE textures, with maybe vertex paint
- when mesh has multiple materials use multimaterial not masks or skins
Some sounds may be made mono instead of stereo, lower bitrate.
And then you (could) strip parts of unreal, it adds a lot of junk models and textures from engine (or added last time i tried ti, in 4.2)
Also determine max size of project for that device you are willing to use.
And get that tool in editor that shows sizes of textures, so you know where to cut most.
