3d games with ios5 crash a lot like infinity blade why?

i have iPhone 5 with iOS version 6.1.4 (10B350)

i tried a few games like:

Catapult king / jungle fly / skyrise / pitfall / and another game of car racing i just don't remember its name

i can't not play these games in my iphone , they keep crashing i dont know why!!

i tried all the ways, backed up my i phone and reinstalling those games, from i tune, from my phone directly, reset my phone to factory settings.. none of these steps helped me out.. and i also searched the net for the answer .. didnt find any answer..

i don't , is it coz of the latest update or shall i wait for another update?!

note.. i began to download and try to play different games after the last update.. before the 6.1.4 i never tried to play any !

Have any of you tried deleting them from the multitasking tray and restarting you iPhone/iPod Touch? Also, are any of them jailbroken?

See:

iOS: Troubleshooting applications purchased from the App Store

Contact the developer/go to their support site if only one app.

Restore from backup. See:

iOS: How to back up

Restore to factory settings/new iPod

my phone is not jailybroken

and i tried moving them from multitasking , and i did restart , and reset

i tried all the legal options .. but it did not helped me at all

still have the same problems 😟

How much free space do you have on your iPhone?

Free space could be an issue, but the most probable cause is the compatibility with device and ios version. Go to a few of the apps on the app store and scroll down to compatibility. Is your ios version/idevice listed there? What gen iTouch do you have?

If the app was not compatible with their iDevice/iOS version it would not let them install it.

This could also be due to the speed of your iTouch and/or the graphics your iDevice supports.

the free space :

6.8 GB Available

6.6 GB Used

and all the games are compatible with iPhone 5

but it keeps crashing

Is this the new 16GB iPod Touch 5?

no .. its iPhone 5 16GB
