My Samsung mobile phone GT 19 158P is turned on repeatedly, so I can't really turn it on, but there is a boot screen. Why?

If you can enter the boot interface, but the phone can't enter the home page, please restart the phone and try. The operation steps are as follows: press and hold the power button for 8- 10 seconds to restart the phone.

If the problem still exists, it is recommended that you take the purchase invoice, maintenance card and mobile phone to the local Samsung service center for professional engineers to help you test.
