My samsung J2 shut down for no reason and restart it self. But most of the time it shut down and i have to take battery out to start
Well, it could be a few things.

First, I would uninstall any apps you don't use (and that can be uninstalled).

Second, scan the phone for viruses and malware. Any of those can cause issue.

Third, if the phone continues to do it, you may have to do a "Hard Reset" to clear everything off the phone and give it a clean fresh start. If that is the case you should back up your personal stuff before doing it. All personal stuff/info.

NOTE: Doing this will clear 'all' the data on your phone, so it is suggested you not choose this option unless you have to, or aren't worried about losing anything on the phone.

Be sure you back up any data you want to keep, to a computer or cloud account, before doing the reset.

To "Hard Reset" the phone...

1. Make sure that the phone is actually powered off.

2. Remove your SD card, if there is one in the device.

3. Press the "Power" and the "Volume Up" buttons, together, until you see the start-up logo on the screen.

4. Once you can see the logo, release the buttons and allow the device to enter the "System Recovery Mode".

5. Next use "Volume Down" button to get to the "wipe data/factory reset" option When in recovery mode the "Volume Up" and "Volume Down" buttons are how to can navigate and highlight what option you need.

6. Once you have selected the "wipe data/factory reset", press the "Power" button to select that option.

7. On the following screen, repeatedly press the "Volume Down" button until the "Yes - delete all user data" option is what is selected.

8. Then press the "Power" button to hard reset the phone.

9. If you took your SD card out in step 2, when the device is up and running again, reinstert the SD card.
