I bought an iPhone XR A- minus condition and out of the box I noticed little flaws to the human eye but as I started to use the phone the first flaw that I noticed was the top left display was not intact with the rest of the phone as the waterproof seal was not applied even though this phone was supposedly gone through a fully inspection, and if I didn’t know about this, it could of later lead to later water damages do the phone. The second flaw that I noticed was the fact that the battery was in service mode and that the battery health was not showing up, this is because either the battery was replaced unprofessionally with out a jc device to code the new battery from the last one or the battery could be a non-apple battery, this is a pain as I keep on getting notifications about a ‘important battery message’. The third flaw that I noticed was that the back panel has been replaced, which I was not surprised of but the adhesive for the new back panel was not applied all over, therefore could cause water to easily enter the device, also the back panel was slightly not inline with the frame as there is a millimetre gap at the Back bottom left of the edge phone where the glass doesn’t meet the edge of the frame. The fourth and last flaw of this ‘A- grade iPhone XR’ is that there is visible dust underneath the camera lens which could of been cause by the lack of profession to put a waterproof seal for the screen and frame or the lack of adhesive for the back panel.
