I've recently purchased a touchscreen device, and unfortunately, the touch functionality is not responding as expected. It appears to be brand new and hasn't been used before, so I'm surprised to encounter this issue right out of the box. I would greatly appreciate your assistance in resolving this matter. Could you please let me know the available options for fixing the touch screen? Alternatively, if a repair is not feasible, I would like to explore the possibility of obtaining a replacement screen. Your prompt response on this issue would be highly valued, as I'm eager to get the device working properly. Thank you for your attention to this matter!
