See, I am a user of tab A7. It does not support an active pen (S- pen), you can buy an Amazon basic generic stylus. If you find this helpful kindly click on the three dots and click accept as solution
You can purchase Tukzer stylus priced at around 400-500. But you cannot get experience similar to an S-Pen. Also as Mohammed321 mentioned about Generic Stylus, you can also purchase those. You can also make your own stylus. Refer YouTube for the same. Most of them work, but don't expect good experience with them.
