Just got the LG GFlex. The stock msg app is horrible.
The app is horrible especially with the stock keyboard. There is really no reason for this much screen to be taken up by the keyboard and text box. here is a screenshot of the stock app with Swype keyboard. you can see one message at most. http://i.imgur.com/ZhrM8rx.png
I've began just using the hangouts for mms with people. I'm not sure if this will work for everyone.
When I tried a couple other messaging apps that looked like stock 4.4 I started sending and receiving double messages. I really want to use another app because the stock version is horrible, but I'm resigned to using it right now until I can figure out how to fix this issue. It's probably my fault somehow, but it shouldn't be this difficult to figure out how to not send double messages constantly.
anyhow, the phone is awesome so far other than the messaging app.
does anyone know how to change the text size/messaging box in the stock messaging app? the settings were no help.
