Hi.. I just joined this subreddit.. Previously, I would buy a brand-new POCO X8 PRO 8G/256G in my next payday near my area on a store. However upon discovering that that model isn't that good for emulation purposes, I searched everywhere until I find a used F8 Pro 12G/256G in FB Marketplace from a seller that was "trusted by local tech reviewers" that is only a little bit expensive compared to the brand-new one. How should I look for a used POCO F8 Pro phone to ensure that I didn't get completely scammed in the end?
