After the last T-mobile software upgrade my Galaxy S9 that i never had issues with.... When im on the text message screen and open to send a picture, the pictures are sometimes blank (until somehow in the background it uploads it to the text message screen). When i try to add picture to text message screen it takes forever to add it. If i get out of it (while its loading the picture to the text message) i have to unselect the picture and reselect it so that it adds it to the text message. Again never was issue until the last T-mobile software upgrade.
