Review on Samsung Electronics Tab S7 & Tab S7+ S Pen Mystic Navy - EJ-PT870BNEGUJ - Premium Stylus for Ultimate Precision by Michael Robinson

I have bought this pen twice and had to return it both times simply because there is no information on whether the 'S Pen' is compatible with previous Samsung tablets or phones. I don't like the fact that there are no instructions included with the stylus, and I have no idea if a special pairing process is required. For example, I didn't even consider that it might be a Bluetooth device until the seller at Best Buy where I got it, maybe not offered it, but neither he nor any of the other sellers at Best Buy where I bought it was able to find out if it's backwards compatible, if it has bluetooth or whatever I think. It just looks like a dark piece of plastic in the shape of a pen. Is there a battery in it? The stickers on the shipping box seem to indicate this, but without relevant information about this product or a way to unscrew and test one of the ends, just don't try to buy it for an older phone or tablet model. I wouldn't have bought it if it had the "Samsung X specific version ONLY" information, but I was dying to see if I could add pressure sensitivity levels to an old tablet. Spring. I think the old tablet is now only used as an alarm clock or as a digital photo in a frame on the wall. I ended up going to another Best Buy store and just bought a new Microsoft Surface Go that is cellular compatible. I'm a graphic artist and the new Surface Go looks like the product I really need.
