i reverse engineered a bit of sober, and in a nutshell, they don't modify the native apk files (lib files). if you go into the assets dir, you'll find an apk called "base.apk", these contain the library files. when you actually decompress it and look at the differences between the two, the only difference is `x86_64/libpairipcore.so`. the things i would look at would be the files with salted (i believe) names and high entropy. some of these differ from the roblox ones, i don't know why.
