What I noticed is that the battery is not lasting, in browser the return key does not work sometimes, in browser the track pad is also non reponsive sometimes.
Also when downloading a file, when u go to file manager to check file size it gives u the full size of file instead of the size downloaded already.
Does anyone else have same issues, is there a better os avaliable.
Answer:
I have a 9900 and I have been running 7.0.0.540 for 9 days and it has transformed my battery life. It seems to be far better than any of the previous OS versions.
