Hello,I have a kindle fire HD. It was new in September. Ever since I had it, it is slow, and locks up from time to time.I downloaded dolphin browser which has increased the speed on the internet but the browser is unstable. I use silk which is slightly more stable but is slow. Is the kindle like this and I must live with it? Kindle is great for reading books and playing music. But I am not impressed with surfing the internet. I am getting a little tired of my browser shutting down time after time too. Any suggestions???
