Hello everyone, as the title explain, i'm just before buying a used Oneplus 3 (originally bought in Germany) and i'm really not sure, what to check for. (for example at MI5 there is the GPS problem, which if a knew before, i could have checked it before i bought)
Is there anything similar with this phone? Were there know hardware bugs with certain models?
Can i somehow check based on serial with Oneplus?
Any advice would be greatly appreciated!

I bought mine couple days ago (used) and everything is fine
Check the following:
1. If the other guy has bought it over the official OnePlus site (very important)
2. Check if the device has locked bootloader or not
3. Check for scratches on the Camera
4. Try pressing the screen a little bit hard to see if it has any flex or weird reaction (He may has changed the screen who knows???)
5. General testing (FP, Calling ETC)

No bugs with certain models (as far as I know)

Thank you very much for your fast reply!
1. Could you advice me further, how to check if it has been bought from the OnePlus site?
2. For the bootloader check does the keypad mode work (*#*#7378423#*#*), or shall i bring a laptop?

thanks again.

You're welcome
You can see check by checking on the receipt. It should have a order number and everything should look legit
No you don't. Just power off the phone and then power it up by pressing the Vol UP + Power button
