If you own a LG Optimus 2X then you might have experiencing the tedious ‘Software Update’ function on your device from time to time. The problem is that if you close it then it restarts automatically after some time. Not only this, another but I would say the most annoying property of it is that it eats your phone’s 20 MB RAM.
However, if you plan to simply remove the application’s package OmaDmclient.apk to get your 20 MB RAM back, then it will get on your nerves as this will cause a problem with your Settings. The smartphone’s Settings and About menus will close then forcefully. You get the RAM back but you face an annoying consequence.
