Hi there. This Stylus is intend for Apple iOS and Android touchscreen devices only. The model "Samsung Galaxy Tab A 10.1 (2016)" is listed as compatible for our Bamboo Ink stylus. A 2019 has not been tested, however odds are that this model is still including pen AES technology. I would suggest exploring the Bamboo Ink models and see how it goes. You could further confirm with the manufacturer of your device (Samsung) that the model you have includes either AES pen technology or MPP. Hope that helps. Best
