Why is my S4 i9505 randomly rebooting after rooting? topic

I rooted my phone a couple of days ago using cf auto root. I haven't flashed a custom recovery yet. I deleted 1 systen app which was the YouTube app so i could install a better version. Then my phone randomly did a quick reboot. It went to the spinning samsung logo and then to lockscreen. It took about 15-20 seconds. It skipped the samsung music that usually plays during boot and skipped the screen that says samsung galaxy s4 gt i9505. And, sometimes the home screen just freezes until i go to a different application (like settings) or holding the home button. Since i rooted, these random reboots hav happemed about 8 times. Today it happened about 2 or 3 times. I've noticed that is triggered when the screen is powering off when i press the power button or after a minute of inactivity when it automatically dims and then powers off. But it doesnt happen like this everytime. However, one of them happened was while i was talking to someone on the phone.


A couple lf people have said that installing the latest firmware on my phone will help. But isn't there any othet way to fix it?

Why is this happening? What is causing this? Will this problem go if i unroot?
