My best friend managed a cellphone store.
Delete all of your risque photos before handing over your phone for any reason. Tell all of your friends and family members this, too.
Please.
Also - there are so many people in "advantageous" positions that you would never realize.
For example - if you have insurance on your phone, and you have a much older phone that you don't want to "pay to upgrade because they changed how contracts work", start an insurance claim. Asurion (Sprint, ATT) lets you see what phone they'll send you as a replacement device and what the deductible will be before actually submitting the claim. If you have an older phone, chances are your phone won't be in stock (currently or ever again.) In this case, Asurion must send you a "comprable" device.
What they don't tell you is:
1. this comprable device must be an upgrade from your current one;
2. The cost of the deductible is based on the original phone based on current value, not the new one.
3. Your contract/payment plan is based on your original device, not the new one.
Case in point, I had an old Note 5 with ATT that I've been paying off monthly based on their payment program. ($825/36 months.) I just finished in April, so the cost of the phone dropped off my bill. My screen had slight discoloration, but I was just going to wait because I didn't want to get a new phone. My best friend tells me all of this, so I go through the process.
Guys, I went from a Note 5 to the Note 8 for $50. It's brand new (not a refurbished device - you can tell based on the box it's in) and it's not on contract, as my original phone was just paid off.
My sister did the same thing with her Galaxy S4 - they initially sent her a S6, but it was messed up. They sent her another one - that one was messed up too. (Or she lied and said it was cracked....she's not an honest person.) On a third resend they have to send you either a "better" phone or a new brand - so they sent her a S8 because they didn't have any 7s.
