My games aren't working anymore, before the android update everything worked perfectly.
What can i do to overcome this problem?
And i don't mean re-install the games, because Real Racing 3 is 1 of the games that ain't working anymore and i have a few select cars you don't just get in the game.
If i uninstal the game i loose those cars.
most likely its something the dev has to address.
I said Android update, but it was the systemupdate.
My mistake
do you mean from ICS to Jelly Bean?
Could be, just got a message that i needed to update, so i did.
It was a systemmessage from sony i think?
how can i check what youre saying?
its hard to tell, you can check your current android version but not what you had before the update.
settings > about phone
android version
and
build number
Now i have Android 4.1.2 and buildnr 9.1.A.1.140
perhaps you have ICS before, does the phone look different now? perhaps the messaging app changed background color, etc?
youre so good (Y) 
ok I get that you had ICS and now JB and that's why some games aren't working as the game/apps developer(s) has to fix this.
