Under advice, I brought my cell phone from them. I had broken the display. They give it back to me after 4 working days, but the display is not suitable for my mobile phone. I take it back and wait another week. They call me, I take it back, but the same story: the touch was wrong. I did this twice more and the phone from the day I brought it 10/01/19 to 11/04/19 the day I picked it up, it was not working. They told me they had a couple of loads of "bad displays", then the oxide had corroded I don't know what. Moral of the story: I took my phone to another phone shop, after 4 days the display is working perfectly.
I'm the MATE10LITE guy, I was too polite with you, I give you advice: order ORIGINAL Displays!
The only positive note is that for the long wait they gave me at least a courtesy phone.
