If you find a reputable seller (e.g., AverageDad on XDA or TradingShenzhen with their "Stable Global" ROM) and you confirm Widevine L1 is intact, jump on it. You will be the envy of every Galaxy Z Fold user.
But if you just want a phone that works out of the box, save your money and get the OnePlus Open. It is 90% the same phone with 100% fewer headaches.
Oppo does not officially sell the Find N2 outside of China. The "Global" version is actually a Chinese unit where the seller has wiped ColorOS (China) and flashed a modified version of the Oppo Find N3 (Global) or OnePlus Open software. You will likely get ColorOS 13/14 (Global) or OxygenOS .
