The Irulu X7 has 512 RAM; FGO can run at an acceptable speed starting from 1GB, using at least 80% - 90% of the capacity. At lower RAM, the game might not run properly; this might be the cause of your problem.

Otherwise, your Android version is more than fine; I ran the game on a slightly older version.

There are several apps that you can use to decrease the quality of your game (like GL Tools for example), allowing phones like the one I have (which is just a cheaply-manufactured local model) to run the game at the cost of one hell of a horrendous graphics. However, GL Tools require rooting your phone to use, and you should not do so unless you are fully aware what you're doing.
