A:AnswerI believe it can connect to 2.4 + 5 Gigahertz. Insignia is one of the Best Buy private lines so why did you not contact them regarding specifications on their product . Honestly the processor is not large enough for the tablet and whatever you're connected to takes a long time to load. I bought it as an extra tablet but I am thinking of replacing it.
A:AnswerYou should be able to go into the camera app and touch the 3 dots to get to settings, then adjust the color mode which is to the right of the screen.
A:AnswerIt has a mini USB for charging. We bought a mini to large USB converter and now anything with a normal USB like wireless keyboard and mouse work with it.
A:AnswerYes just going to Amazon and type in looking for a digitizer if the screen is broken or image quality is bad. You can find all the parts probably through Amazon and eBay
