Device: Samsung Galaxy S6 Edge+
Android Version: 5.1.1 (_0024)
I keep getting error "Unable to attach file." when I want to send a picture as a text message from my gallery. I also cannot download pictures that are sent to me. The status just keeps saying downloading. I have tried using different text message apps but the issue will transform into errors saying I cannot send or the download failed. I can temporarily resolve this issue by resetting my phone to defaults and re-installing all my apps. I have done this twice now. It only resolves my issue for about a week then it starts over again. I am able to use data, send regular texts and phone calls without issues. I have also tried disabling and resetting the cache of my messaging apps.
Does anyone have other ideas for me to try? I really don't want to factory reset my phone again.
Thank you,
Lucas
