@vickienm @rtbbf1967 Join the Windows Insider program. You may never see Windows 10 Mobile on the 640 XL coming from AT&T. you never, know. You'll also be on a later build than whatever it is that AT&T would decide to send. If you want help on performing the update, just ask or read the previous suggestions!

You don't have to do a fresh-install, or at least I wouldn't, initially.
- Back up everything, using the internal backup app (which will save the data to your Live account)
- Do a full-reset
- At this point, if it were me, I'd do the restore as it resumes from reset, and see if things are fixed. Worst-case, you reset, a second time. IME, this will fix it without another reset, at least 90%.
- If it's not fixed, reset again, and then very carefully re-import things, trying to stick to data-only on the restore, to avoid importing the corruption, again.
I set my mom up with a 640 (she was a VERY resistant smartphone-convert, but needed text for some financials), and I gave it to her with Win10m at the outset. She's VERY happy with it, doing things on her phone she never thought possible (texting a LOT, some browsing, occasional emails, managing her contacts and some appointments, etc).
*If this (or another post in this thread) fixes your problem/issue, please mark it as "accept-solution", and I'll tag it, to make it easier for others to find the answer(s). FYI: I'm an AT&T end-user, just like most of us in the forum. Thanks.

@Kristi_6 yes, Windows 10. Explain what you mean by having a hard time sharing; could you not figure it out or did it simply not work?
You an Hard Reset your device as suggested. Since I didn't see the steps describe I'll list them for you.
First back up - I suggests you be on Wi-Fi when you do this -
Go to Settings
Update and Security
Back up now
Reset your phone
During the reseting process, after the gear spinning and you start configuring you'll have the option to restore your backup. I suggests you be on Wi-Fi when you do this.
