[itsall4u]

Hi to all
I bought a new Mobile QMobile Noir A5classic with android 4.0.4 1 month ago.
it was working great but now it shows one problem. While typing sms, I want to attach a file or contact info, When i tap on any attachment oprion it show the attachment screeen for a sencond and return back to the messaging screen. Similarly when i want to send a message to a group. When i tap on the add contact icon in messaging screen. it show the contact for a second and auto return to the messaging screen. It was working great but now from 2 days it shows this problem. I restarted cell phone several times but.......

Is there any solution????
Thanks in advance to all

Sounds like an MMS problem...
-Do you have Data enabled?
-Have you checked the APN setting?
-What SMS App are you using?
