I just upgraded last week to the Samsung Galaxy s5 and now I am thinking it was the worse mistake. :-(
My gf has a Samsung Galaxy S4 with Verizon. Since I have upgraded to the S5 (which I have AT&T), 95% of the pictures she sends me do not come through.
Just get a grey picture with a red triangle with an explanation mark in it.
She gets all the ones I send to her and she is able to send and receive to anyone else and has never had an issue.
We have checked turning off wifi, checked physical locations, even sitting side by side at her house and pics from her do not come through to me 95% of the time.
Extremely frustrated. Any help will be GREATLY appreciated.
