It seems the MMS on this phone is a bit quirky. I was previously using Textra and had noticed that some people could not receive my pictures. On an iPhone it gives a message about message being too large and on an s3 the image is received as a sound file. I uninstalled textra and went back to the stock messaging app. The stock messaging app says the file is to large or other error. Seems to be quite a nonspecific error since the images are only 10 to 30 kb. I tried taking a screenshot and sending the screenshot, but the app refuses to resize the image and gives up saying it is too large. Has anyone else had these issues?
