I know you have a tablet but thats doesnt mean you are good enough to spam 4 star song
The ploblem might be you are spamming them like crazy without mastering OD and AR
I know this is a word from a 6 digit noob, I can FC 4 star song with shit acc but I won't, mastering AR 7 - 8 and have a good acc would improve myself in the long run
