This afternoon all was fine and good until i installed a 13mb app. All of sudden my phone started displaying 'XOS LUNCHER HAS STOPPED'

That's what it keeps displaying. I've uninstalled many app (even the 13mb app) and even deleted videos to make available more storage/space

My phone storage stands at 1.8Gb while memory card storage stands as 3GB but there's no changes

It until I removed the memory card things returned to normalcy. But my important apps, video, pictures is on the SD. in fact I'd have sent the screenshot of the irritating display but it's in the SD

I'm helpless like this pls help me out here

Install another launcher
Like HIOS, Microsoft launcher and co

Then set it as home screen launcher

After that
Locate settings, then apps, then show system apps

Locate cos launcher, force stopp, clear cache, clear data

And try it as your phone launcher again

Thanks boss...
