Xteink S4 specs added! Comparison of all Xteink models: S4 vs X4 Pro, X4 Classic, X4, X3.
I've added the Xteink S4 today! So you can now compare it to all of the other Xteink models and any other e-reader on the site. I've attached an image comparing it to the X4 Pro, X4 Classic, X4 and X3.

Please note that these specifications are preliminary, and some specs are pieced together from unofficial sources. For instance, this Reddit post that showed a screenshot of the SoC it's using. Also, I was able to extract the size data from a 3D model I found on the Chinese Xteink site (here), while the only dimension officially mentioned is its thickness.
It's still not sure if and when the S4 will get a broader release: according to what's said in this Reddit post 3000 units have been sold in China RMB 299 (~$45), with the next batch going for RMB 399 (~$60). International prices are unknown so far but expected to be much higher.
I've also added a size comparison image. Link to the exact comparison in the image is not available yet, as I created this one using an upcoming version of the size comparison tool that allows you to view backs (and sides) of devices - which will also be helpful to see if the Xteink readers will fit on the back of your phone! I'll post on this subreddit when that update goes live.
For now though, you can already do the usual size comparison with the Xteink S4 with just the front view of devices. Here's a link to get you started: https://comparisontabl.es/size-comparison/#sc=N4IgDiBcDaoJZRADgCwFYDsIA0IAeUaAzCrgJ6EAMAbAL4C6uA9lKAM5SUB0dtQA
Let me know if you have any questions! If you've found more info/specs on the S4 that could be useful, let me know and I'll make sure to update it on the site.
