I bought an S Pen to use with my Samsung Flex Alpha after being told it was compatible and could be bought separately ( I was told this by both Best Buy and Samsung- this was one of the reasons I choose to purchase the Flex Alpha versus the Flex). However, after speaking to both best buy and Samsung for a long time, it was discovered that the S Pen could not be charged on the Alpha due to there being no slot. I am also not convinced that it would be able to connect without the a slot. The rep from Samsung seems to believe that if you have another device with an S Pen, the S Pen will also work on the Flex Alpha. I'm a little doubtful as again, there is no port to charge / connect it to. If anyone ends up being able to buy an S Pen and use it with the Flex Alpha without having another S Pen compatible device, please let me know!
