[Q] Dead apps? topic

Hello, i was testing some things under my brothers RAZR i and then he told me that there was a lot of dead-apps which at the moment you run them they self-close without giving any option or FC so called... and other apps has a lot of issues under this Android device, it's weir because in my Atrix most of the to-mention apps work...
Some of them was a flashlight, speed test, 9gag as is an example of the ones which works really bad.

We did wipes and started over, the only app that got fixed was Chrome, but then the other ones crashed like before, is really strange since they where working...

He is using JellyBean official rom, non-root, non-unlocked bl.

Any way to solve the apps issues??

Thanks.
