Yes, if they can’t make a phone that will appeal to the masses as well as the 3D addicts, they are sunk. Yes, I am skeptical after looking at the history of 3D and photography. My prediction will have, I am sure, no effect on their sales. So far Rokit has continued to provide updates, so it is the most successful or perhaps optimistic 3D device purveyor. The lack of a microsd slot is a big deficit for many people. 3D needs lots of space if you want to have both pictures and movies on your primary display device. Cloud storage can be iffy and expensive, so local storage is a must.
My Realist format photography lasted from 1962 to 2010 until the demise of Kodachrome. I could always get my cameras fixed and they worked perfectly. One wishes for such longevity in this era of device du jour. I could still rekindle them with poorer quality film.

My two initial gripes with the Lume (pronounced "Loom") Pad which I received a few days ago are 1) the lack of a microSD slot (which is present on every other Android device I own). I was initially unable to access external content with a usb A thumb drive and the supplied adapter, but was able to do so later from a card reader with usb C connector. But having a drive sticking out of the tablet is much more clumsy than an internal slot. And total built in storage is only 128 gb.
2) the low resolution of the ST (stereo) and 4V modes on the device. Others have mentioned the pixel grid or window screen appearance seen in these modes but they apparently are not bothered by this. I find it quite noticeable, in part because I tend to view at about 14" (which is a comfortable focusing distance for me without glasses) rather than the recommended distance of 16-20". I do not see this "window screen" effect at all when viewing on any of my other glasses-free 3D displays including the much older 10.1" Freevi/Commander 3D, with overall resolution of 1920 x 1200. It all looks sharp and smooth to my eye in 3D. Different technology.
When viewing the supplied images in ST then 4V on the Lume Pad, I noticed that the "window screen" appearance seemed milder with ST display and more pronounced with 4V, presumably because resolution was half in ST and one fourth in 4V mode, of the basic 2560X1600 resolution? Of course the window screen effect is also more noticeable on certain plainer backgrounds, and on the playing card image there was a pronounced jaggedness on the card edges, especially diagonal edges.
In general, I personally thought that most images (theirs and mine) looked better in ST mode than 4V. Full depth, and no artifacts from the creation of the extra views, which were sometimes a problem. I would prefer a sharper full depth image rather than the ability to move my head around to different viewing angles, with less overall depth. One exception among my own images was one with way too much depth (foreground too close) , that looked better in 4V.
I noticed that the most recent upgrade of Leia Player on my Red Hydrogen One allows one to stay in ST (stereo) mode, and/or to choose from 2D ST and 4V with a single click without having to scroll through all the choices everytime you advance to another image or want to make a comparison. I hope that the Lume Pad version will have this ability soon, rather than reverting to 4V each time and requiring one to scroll through the 3 options when making a change.
I am glad that there is a new "3D" tablet option out there now, compatible with stereo viewing, even though "we " are not their main target market. Linda N
