For anyone looking to how to move beatmaps and skins from PC to phone, here's how

[SolsticeSpectrum]

1. Navigate to C:\Users\YOU\AppData\Roaming\osu
2. Connect your phone to PC and naviage to Android\data\sh.ppy.osulazer\files
3. On the phone storage delete the files folder (not the one you're in, the sh.ppy.osulazer\files\files one
   If you're not sure if it's the right one, It contains bunch of differently numbered folders like 0-9 and a-z
4. Delete client.realm and client.realm.lock
5. Now copy files, client.realm and client.realm.lock from PC's osu folder to the phone essentially replacing what we deleted
6. Now you should have all skins and beatmaps transfered

IMPORTANT NOTE: client.realm is an odd thing and if you don't delete files folder and just merge the folders, it will get very confused about incorrectly placed files
