BLACK SCREEN ON MY SAMSUNG GALAXY RING.

Hello,

I'M IN NEED OF SOME SERIOUS HELP WITH MY MOBILE PHONE PLEASE!!!! CAN SOMEBODY PLEASE MAKE MY DAY? I JUST GOT DONE WATCHING A VIDEO ON MY PHONE, I PUT IT ON STAND-BY, (SLEEP MODE, I GUESS) THEN ABOUT 5 MINUTES LATER I SEE THE SAMSUNG LOGO APPEAR ON THE SCREEN, I THOUGHT IT WAS GOING TO POWER OFF THEN BACK ON AGAIN LIKE IT USUALLY DOES EVERY ONCE AND A WHILE, BUT THIS TIME IT DIDN'T. THE SCREEN LIT UP BUT IT WAS BLACK AND STAYED LIKE THAT AND NO MATTER WHAT BUTTON I PRESSED IT JUST HAD NO REACTION, NO VIBRATION, NO LITTLE NOISE, NOTHING!! I REMOVED THE BATTERY FOR A MOMENT THEN RE-INSTALLED IT, PRESSED THE POWER BUTTON AND THE ONLY THING MY PHONE WOULD DO IS LIGHT UP THE SCREEN BLACK FOR A FEW SECONDS THEN POWER OFF THEN POWER BACK UP JUST TO LIGHT UP THE SCREEN AND NOT EVEN GETTING AS FAR AS TO DISPLAYING THE LOGO AND WOULD POWER OFF AGAIN IN A CONTINUOUS LOOP! I DID THE HARD RESET ON IT AND STILL IT CONTINUES TO POWER OFF AND ON, I TRIED TO PUT IT IN SAFE MODE AND IT WOULDN'T EVEN DO THAT FOR ME. I'VE REMOVED THE BATTERY FOR 24 HOURS AND STILL NOTHING. I REALLY LOVE MY PHONE, I NEED IT BACK. I'M SICK OF USING A SLUGGISH, NOT SO COLORFUL, PLAIN AND CHEAP ANDROID SMARTPHONE THAT TAKES FOREVER TO DO ANYTHING. PLEASE, DOES ANYONE HAVE ANY SUGGESTIONS OR REMEDIES THAT WILL HELP ME FIX MY PHONE AND MAKE MY DAY? THANK YOU ALL FOR TAKING THE TIME TO READ THIS MESSAGE OF DISTRESS.
