Do you have a lot of txts stored on the phone? if you do, that will slow down the app.

Hi, mates.

My messaging app is getting slower now, when my Xperia M2 updated to the latest firmware of kitkat.

it looks like take much time to send a message and if it's still loading for sending the message and I hit the home button or get out from the app, my message will be sent and become a draft at the same time.

I don't know what's wrong with my phone though.

I tried factory reset and flashed it, but there's no change of it.

can anyone help me?

@Ayas

Have you empty the messaging app? 

also it seems like a network coverage issue rather than a phone issue.
