A:AnswerYes, it can be used for zoom. You just download the zoom application from the google play store.
As far as other work, it depends on what you do. I wouldn't say this is the best machine for productivity due to how cheap it is, but you can do video calls just fine.
A:AnswerNo, the Samsung Galaxy Tab A7, T500, does not come with a stylus. I purchased a stylus for $1.98 and it works with the touchscreen function. Haven't tried writing notes yet, but I imagine it would work with an appropriate app, but you would have to use the soft, rounded end, not the hard, pen-type end.
