Okay I kinda fixed this, I putted some tape into the stylus so that it does more presure and therefore it stays, a few months later my stylus piece kinda broke but it was still holding, today I am on Venezuela, here everything is expensive, the tape fell off, so if anybody knows a permanent solution to this please tell me, I thinked about putting tape inside the stylus hole, that is easier on the new 3ds or new 3ds xl but on the new 2ds xl it is really hard. also my 2ds xl is fucked up thanks to family (screen scratched, heavily scratched on all parts, fall damages)
