I have a Galaxy s4. Every time I send a text, my friends get it twice. Also, when I'm typing a text, the letters are sooooo delayed. It's almost like my fingers are moving too fast for the text to register. It's really annoying. Can anyone help me out?
If using a third party messaging app, make sure you set it as the default messaging app. You can find this setting in either the third party app itself or within your phones' own messaging application. Selecting the messaging app as the default will stop duplicate text messages from being sent. Again, if using a third party messaging app and you're experiencing text message lag, your best option would be to contact the developer of the app.
