My daughter just gave me an Android tablet MID_M706S. She had misplaced the user manual & I have finally gotten it online, but I was trying to download the free Kindle app from amazon & I can't figure out how to get the download to show up. Amazon is asking for a wireless phone number & my device is not a phone. Does this mean the Amazon apps only work if the android is a phone? Also if anyone can tell me how I can find a user manual I would appreciate it.
