IPhone 4S loses GPS accuracy

I just fixed this after 2 years. First- delete the contact altogether. Second - delete every single message the person has ever sent you, including any group texts they are in (if it's not obvious to you, search for their name, and when the messages come up, swipe left on them and hit delete). Third- re-enter their contact, being sure that there is a 1(xxx)xxx-xxxx format and that the selected type of number is iPhone (even if it Is not).

Send a test message. If it doesn't work, do a reset and do it all again. If you don't delete every single old message, it won't work. It worked for me!!

I have no idea what the original problem was because I share contacts with my husband and he could text these two contacts. I just know this worked. Apple tech even said she was going to write it down to share because she had no idea.

That's not a battery problem unless it powers off while you are trying to connect it to a computer / powered USB hub to try and pack up the photos.

Taking it to Apple for service won't get the data back as they erase the device if it gets swapped. If the battery indicator is not showing, it could be a bad battery (even some new parts are DOA), the connectors failing or the control circuitry on the main board is faulty.

Worst case, get a quote from a data recovery service and understand if they charge if they cannot get back what you want. Be careful - some say if any data is recovered - be sure to specify you only want photos if that's what you're considering paying for.

If you have a Mac - check out PhoneView to restore the photos. There are lots of other apps, you can search them here for specifics but you might have passed the window where you can get the photos back.
