My iphone keeps randomly turning off?

It randomly turns off when i search something up even with Wi-Fi around. Its a 2G btw.

Something has broken in your phone's software. What you will need to do is open iTunes, and synch all your contacts, apps, and anything else you want onto your computer. Then, you will need to restore your iPhone by clicking on it in the iTunes taskbar on the right. It will do its thing, let it run its course, then create a new phone when the option pops up, (if it does because it is an old phone). Then, just synch all your apps, music, and contacts back over. It should work with no crashes.

Check your setting of auto phone off. Ether restore your phone.
