I have a small crack on my iPhone?

On the back there's a line in the corner, not really deep but you can feel it

i don't know if its something tog get fixed?

I'm not sure you Technically asked a questioned… Sounded more like you were simply giving an Undecided Opinion. Lol

Anyhow, if what you're asking is IF it's worth Fixing, if it can be fixed and/or if you 'Should' fix it… Then:
Yes It can be Fixed & No Not that expensive to fix.
Should you? Only if its really bothering you or if you're planning on Selling it.

Otherwise, just don't look back there! (or put a sticker over it)
