Hello, I have cracked the glass on a Traveltek 9" Android Tablet, and the device won't work properly. Everything is visible, but the device is not responsive. I have some backgruond on PC's and laptops, but zero knowledge of Androids. I want to replace the glass digitizer, but I am finding it difficult to locate a Traveltek replacement part. My question is this: can I replace the glass with any other manufacturer's part? Are they all interchangeable? Any advice would be appreciated. Thank you, victor1244
