Apps not working after JB update

[AnilGautham]

I recently updated to the Android JellyBean 4.1.2

I am not able to even open games like Temple Run 2 and Subway Surfers both of which were running perfectly before the update.

I do not want to uninstall and re-install for fear of loosing in-game data.

Can you please state the reason for this and also the solution???

If u are caring for data like coins or scores for the game better copy them in to your compuer from Internal Memory > Anroid>data ..i would recommend u to have a fresh copy for those games

That would be my last resort.

I have a doubt as to whether the JB is using up more RAM than the ICS.

If this is the case then no use in uninstalling.

Thanks for the tip,though.

As For Your doubt Both ICS & JB uses same amount of RAM

• 380 MB of RAM is available for use in Xperia J Android 4.1.2 Jelly Bean firmware which is same as in ICS, so no change in that.
