I have 8 gb internal memory . In that 4 gb usable.
But when i update the app my internal memory decreased. It looks like it not able to delete old apk file. And store new apk file. Or some like that . now i have only 350 mb remaining . I don.t have any personal file in my internal memory. Please look at this issu ASAP. I chat with asus customer care suppot and they give me suggestion to 'wipe cache partiton'
Still its not working. I hope u understand the problem..
I upgrade to lolipop before and after that i face this memory issue.
