I start Google and its ok but when i search something Google crash. I have the same problems with games when i open them they crash. How can i solve this problems? I'm on HTC Desire 310.
Restart the device in safe mode. This will temporarily disable all third party apps that you downloaded, so you can see if there's a bug in the system or just a conflict with an app.
If the problem persists in safe mode you could try a cache partition wipe via recovery mode.
