Having or not having a stylus is not really the decision making factor when it comes to smartphones but it would be interesting to see Huawei try to compete with the Samsung Galaxy Note 8 with a stylus of its own.
According to Evan Blass, the upcoming Huawei Mate 10 Pro could be coming in with a pen or stylus of its own but unlike the stylus on the Note 8, the one for the Mate 10 Pro might not be stored in the device itself.
The leaked image posted by Evan Blass showed the stylus drawing on a piece of paper. The image suggests that the pen would be able to send a signal to the device to mirror what it has drawn on the paper.
There were some that speculate that it might be a new partnership with Moleskine and that this is a Moleskine pen but we will have to wait and see.
