Just bought a tablet Coby model MID 7042. Although the Wi-Fi interconnection is perfect in all ocassions, almost never the browser connects to internet. Is there any add-on to be installed besides what comes from factory? The systems tells that the Android version is 4.0.3. Is there any problem with the operating system? Where should go to for getting the best information about these tablet? I would like to know more about how to download and install the apps. Thanks for your kind attention.
