I thought jump from 11 Pro and 15 Pro would be a big jump compared to say jumping from 13 or 14 series.
What were you expecting?
To give you context I’m currently using 11 Pro and it will turning 4 years very soon.
How did you manage to get that level of damage to the phone?
I usually sell them so I can recoup some money when I upgrade. I sell them in private.
