My iPhone SE is going black, showing the apple logo, then has a screen glitch before going back to the black screen and doing it over again?

An employee at an Apple store might be able to help you.

Just do a hard reset, that normally fixes that type of problem.

Press and hold both the power and home buttons for around 10 - 15 seconds.
Let go once the Apple logo rea-appears.

Nothing is erases, it just forces the phone to do a proper restart, as if it had previously been turned off completely.
