This is equivalent to something I called the "QWERTY paradox" more than a decade ago:
Back when the Smartphone market exploded, people disliked typing on a touchscreen and repeatedly stated that they want a device with a physical keyboard.
There was plenty of evidence, surveys, market studies, trend predictions, devices for these "Messaging-centric" use-cases were always part of this market-demand roster.
But whenever someone answered the call and built a Smartphone with QWERTY keyboard, the product failed commercially, simply because also to people claiming they want such a phone, at the point of sale they were less attractive than their slimmer, lighter, all-screen counterparts.
Every major vendor went through this cycle of learning that lesson, usually with an iteration like "it needs to be a premium high-spec device" --> (didn't sell) --> "ah, it should be mass-market" --> (also didn't sell).
You can find this journey for every vendor. Samsung, LG, HTC, Motorola, Sony.
The same lessons were already learnt for small-screen devices: There was a "Mini" series of Samsung Galaxy, LG G-series, HTC One, Sony Xperia. It didn't sell, the numbers showed that it didn't attract additional customers, at best it only fragmented the existing customer-base.

I bought Motorola Droid 4 when it came out. I was so desperate to have a new phone with physical QWERTY, that I bought it blindly, even though it wasn't available in Europe, even though I have never seen it, even though I knew it *didn't support mobile networks* in Europe for a few months, to be fixed by an update. I had to use a coworker who was going on vacation to Florida.
When it arrived, the first thing I saw was that the black screen during boot shines bright blueish, horribly bad contrast. Then when image appeared, I've learned that it has two subpixels per image pixel, for efficiency. This made single color areas show the pixels very visibly.
Then I took a photo. The quality reminded me of a Sony Ericsson Walkman phone I had 6 years back, except the colors were much worse. Everything was blueish. It had a physical (touch) "search" button below the screen, but companies like Google didn't seem to understand why it would be useful to search for anything, so most of their apps didn't react to it. Especially Gmail.
But hey, I could touch-type any long message, and I could use SSH client conveniently (it even had a physical CTRL button).
Other than the keyboard (pretty solid too), it was one of the worst phones I ever had. So yeah, based on that model the market decided that "nobody wants keyboard phones", and the Droid 5 never came out.
Because it's easy to blame the most standing out feature.
This is an odd conclusion considering that the Droid 4 was already the FOURTH iteration of a QWERTY device from that ONE brand on that ONE carrier, each iteration selling less than the one before as each faced more competition.
If you're interested, the actual reason for the end of the Droid QWERTY series was that the entire "Droid" brand was a Verizon-exclusive product-line with a big focus in sales and big budget in Marketing, just to compete with the iPhone (which was not available on Verizon until 2011).
For a vendor to win a slot in that lineup meant that Verizon Sales and Marketing put all weight behind selling that device, no matter what device it is. This made the Droid 1 and 2 a huge success, not because of the product but because of the sales channel.
But in year 3 (2011), the iPhone launched on Verizon, which put a huge dent in both sales-focus and budget of Verizon's "Droid" product-line.
Later that year, Droid 3 launched but was selling significantly less than its predecessors.
In that year, Verizon instead sold 6.5m iPhones (up from ZERO iPhones the year before).
So Motorola had to cut their losses on the already ongoing development of the Droid 4, the device was redesigned for a much lower total sales-expectation and then launched in 2012.
But the sales turned out even lower than expected: By Q4 2012 Verizon sold 14m Smartphones, with 10m (!) of them being iPhones.
The most successful Motorola device of that year was the Droid RAZR MAXX HD, a non-QWERTY flagship.
It was clear: That QWERTY keyboard didn't drive sales.
