i can say this, it does not have playstore verification licensing in effect like a few games do like assassins creed, my room mate plays on her phone off an APKPure download because nexon mislabeled a few phones as incompatible, her phones 2x better than mine spec wise.
if it can run on root but other people are having issues im curious if theres a remnant file of something its picking up within it's directory and insisting its a modded file even if its not... idk nexons really not the type of company to be smart about modding/hacking in my experience i made a character o GMs back when demon first released and botted up to 150 or 130 or something while using a god mode wz edit.
if there's any issues im willing to bet its a remnant file of some sort or something trying to get access to it or the more likely scenario the game hates your phone.

bottom line nexon tends to leave the bare minimum to server side while making almost everything including breathing be client side to a point, im willng to say someone could make a public cheat for this for god mode at the very least without ban detection.
- prove me wrong and add vac when there isn't a normal vac item in game currently to my knowledge (90% sure this would red flag since we dont have meso magnet etc....)
hell if anyone can prove me wrong ill give you access to the account im building up right now star force 45 unique potential gears etc...
