The rear camera glass broke
My HTC desire 626 rear camera glass broke it should be repaired by service center or not please relay
It is completely your decision. If you can find a service centre, it is usually your best bet, but usually rear camera glass replacements are fairly easy to carry out on most models.
I also had that phone and had to take it apart to change the battery so I realized the camera glass is actually part of the middle housing, which you can get for less than 6 bucks. All you have to do is remove the back and take the middle housing off by unscrewing the screws that hold it in place, replace with a new one then screw the screws back and snap the back back on. There are 2 diff types of screws btw, one takes a tiny Phillips head and the other is like a *shape.
