A:AnswerNot sure if you can transfer photos directly from an iPad to the Samsung tablet. If you decide to "straddle" the Apple and Android worlds I recommend using Google Photos for photo storage. Google Photos works on both Apple's IOS and the Android operating systems and stores your photos in the cloud so you can see them on any device. Just visit https://photos.google.com/ to learn more.
A:AnswerMany apps available from multiple sources. The OS on this one allows for side-loading apps by loading the files via USB and installing. You can even write your own apps using the developers kits available for free online. Not sure what masterwriter is but it would have to be an Android application to work.
A:AnswerDepends what you use it for. If for gaming, it doesn't last that long. If just casually used, can last whole day checking emails and surfing the net.
