In short: Bought a used Tab S6 and the screen recognize my fingers flawlessly, but it won’t recognize my Spen Things I’ve tried already: Going into settings and changing stuff, did nothingFactory reset, nothingTry another spen, nothingTry the spen on other Samsung devices, works like a charm with both writing and button usage Returning the tablet is not an option so I would like to know if I can fix this or just accept that it will not work with the spen It is to note that the screen is kinda badly glued into the device so maybe they changed the screen and didn’t connect the ribbons correctly? Or the screen they installed just doesn’t work with the spen?
The Samsung devices that support the S Pen have two separate digitizers, one for fingers and the other for the S Pen. So it’s entirely possible for one of them to fail while the other continues to work, as in your case. There’s another thread on a Galaxy Note 10 full of people who are having the same problem as you, along with several suggestions and examples of things they’ve tried that have fixed their problem. Take a look and see if anything there helps. Why does my tablet respond to S-Pen but not my fingers? - Samsung Galaxy Note 10.1 - iFixit Personally, given the condition of the screen, I’d be tempted to open it up and check the connectors going from the tablet to the display. Sounds like you’ve either got a bad connection or possibly a bad (or damaged) display.
