I have an i phone4 i dropped it and the screen fell out and u can see the sliver part where the screen was and back its all smashed can it be fixed.

@dee30 sounds like you need a new display, It is a bit of a tedious repair but not that complicated. Use this guide for the repair. You can get the replacement either from ifixit or do an online search.

Yes it can be fixed. If you take it to a repair center they can replace the screen and the back casing too. As it’s an iphone 4 the cost might not be as much due to the parts being cheaper, just depends what they charge for labour.
