They are usually no fraud and original, you crashed the most expensive version
The display should not exceed 120 $
I find plenty, all described as amoled, pay attention to the finger print sensor, don't buy just the glass, full unit!
Also, the pro is not an Explorer, as usual, read reviews and Feedback, you have buyer protection, I never encountered any issue.
Last thing, if you are insecure if you are capable of changing the display, buy the version with frame (around 20 bucks plus) it's more convenient for beginners, ground yourself, pay a lot attention to the battery while dismantling!
Good luck.
