Ibrahim88, I am sorry that you are experiencing stalling and freezing with your TU7000 TV. To optimize the smart TV performance, please try Device Care option under the Support Menu. Go to Settings > Support> Device Care > Start Device Care. This service checks memory and frees up unused cached memory and closes background apps. I hope this helps to solve your concerns.
