For some reason Pandaapp didn’t work on my (or my wifes’) Galaxy Note II.
You can also download Blackmart (search for the .apk file), depending upon your principles regarding cracked software.
I bough the European version of the N2 (easily available in China if you go to one of the big tech malls. The HK version is fine too) and it does have the Play store on, but even so many apps say they’re not available in my region. Sigh. You can get around this sometimes by installing a VPN, assuming you can find one that works now. Recently China ‘improved’ the Great Firewall so many are still broken as a result.
You can also find many .apk files on websites for aps if you do a search. All you have to do is download the .apk file to your phone, or download it on your PC and transfer it, then find it using a file manager app and run it to install.
