stop lying to others that your apk file is safe, your "proof" is actually retarded
It really is safe. i have tested it in my phone, made the app, tested in other phones, viewed the code and it did not include anything that could infect your phone. after all, its made with sketchware.
give me the source code, i will dig through it, if you dont then thats a huge flag
lets just say that the phone it was in broke.
