I had my iPhone 6 Plus repaired the screen is totally cracked I went to an outside vendor it cost me $60 I started to have issues with the phone it would shut off it would blur it would look like static on a TV screen and it would shut off at times so I went to Sprint my carrier and told them the phone was going crazy they sent it out when it came back they gave me another one because they said they couldn’t fix the issues with my original phone of course when they give you another phone it’s not new it’s a refurbished one it actually worked out for me because the one they gave me didn’t have a single scratch on it I’m very picky about having scratches or nicks on my phone and I did have one nick on my phone and that was bothering me so now I have the same phone but totally brand new except one main factor remember it’s a refurbished it does the same thing that my other phone did and sometimes other stuff as well so yes you can get it done on the outside as long as it’s done correctly they will never know because as you can see I was able to send it out and they gave me another one the fact that the one they gave me now is giving me issues it’s to be expected because I got a refurbished one which means it’s a phone that belong to somebody else and was fixed so unless you get a brand new phone any phone you get from them as a replacement is a refurbished phone And they are supposed to give you a loaner while your phone is sent out if they don’t have a loaner they can call another store and find a loaner for you
