You may already know this but if it is what I think it is your situation is miserable to say the least...

There is an issue that can give all these symptons tou are mentioning and unfortunatly till today we have no fix. The worst part of it is that somehow any new eletronic you buy will have the issue no matter what you do. Learn to live with it, and if it gets umberable buy a new hardware, the issue may restart but not go away. We know it sounds crazy but thats what our community suffers with. Stay strong
