iPhone 6s (Sprint)

I MIGHT ALSO HAVE AN IPHONE 7 (STRAIGHT TALK) 32gb, black. I upgraded a while ago n tryna upgrade one more time. I don’t need it so it sits and collects dust. This phone should go to someone who has the $$$ to fix it or get it fixed. I’ll INCLUDE THE EARBUDS COMES W OG BOX (SEE PICS) Thank you for taking time outta your day to look at my listing! Be blessed! SPRINT locked (PAID OFF) The screen just went black on me one day. Always had protection on it. I’ve left it on the charger for a whole 24 hours and it never turned on. Battery maybe? Screen problem? It’s definitely fixable I just can’t get it fixed. No breaks, cracks, scuffs or scratches. The only problem is it not charging or power on.
