I have the Samsung Tab E 8" for almost 3 years and it is amazing. I think Tab A is the WiFi only version of Tab E. The battery last forever and the screen super bright. I just used it on a 5 hours United Flight watching movies the entire trip.... still have over 60% battery left at the end of the flight. I also used it as my Daily Waze device as I have T-mobile plan on it. Unlimited streaming video anywhere I go .. been watching YouTube TV and Netflix on it... so much better than watching on a 5.5" phone.
