mohona95,
Thanks for letting us know. That is certainly not the experience we want you to have with your device, and we will do everything we can to help you. That said, we noticed that you are running a dated version of iOS. When you have a free moment, please use the link below to update your device.
Update your iPhone or iPad
1) Back up your device using iCloud or your computer.
2) Plug your device into power and connect to the internet with Wi-Fi.
3) Go to Settings > General, then tap Software Update.
4) If you see more than one software update option available, choose the one that you want to install.
5) Tap Install Now. If you see Download and Install instead, tap it to download the update, enter your passcode, then tap Install Now. If you don't know your passcode, learn what to do.
The reason we ask you to update is because updating your device is a vital troubleshooting step that can potentially resolve your issue.
If updating to the latest version of iOS does not resolve your issue, provide us with specifics on what you see for more help.
Thanks for using the Apple Support Communities.
Cheers!
