Both tablets look quite similar, though, then again there's only so much that you can change in a tablet's design.
The Samsung Galaxy Tab S4 starts at £599 in the UK.
In keeping with recent Galaxy devices, the Tab S4's back is all glass. This is priced at £649.99.
Checking out the internals, the Tab S4 is more powerful in every way. While the Android market might be a lot bigger than the iOS market, Apple has done a superb job if keeping customers loyal to its OS platform, something which Samsung doesn't really have.
"The Samsung Galaxy Tab A 10.5" also gives parents the control to manage content and usage time with Kids Mode, Samsung's child-friendly tablet interface created to make learning and entertainment simple, safe and fun.
There are relatively thick bezels around the frame of the Tab S4, and in the top there is an 8-megapixel camera on the front. The handset sports a 13MP rear shooter with LED flash. It comes with either 64GB or 256GB of storage which is still expandable via microSD up to 400GB.
DeX can also let the Tab S4 hook up to external monitors for dual-display productivity work with a separate USB Type-C to HDMI adapter.
Speakers are tuned by audio company AKG. Samsung specs the Tab S4 with a 7300-mAh battery that it claims is good for up to 16 hours of video playback.
DeX allows for a light computing experience.
Samsung is due to announce the latest iteration of the Galaxy Note smartphone next week, which it said will hit shelves sooner than previous years. It was first introduced in the Galaxy S8. When docked in the Book Cover Keyboard or launched from the Quick Panel, Samsung DeX will give you use a more desktop-like experience, complete with multiple desktop-style resizable windows for your Android apps. Sadly, the video does not show the smartphone turned on, or anything around the S Pen functionality.
The Galaxy S10 is already one of the most anticipated phones of 2019, considering what we're seeing in leaks these days.
In China, the biggest market for semiconductors, Samsung faces an investigation over allegations of collusion in chip business along with SK Hynix Inc. and Micron Technology Inc.
Samsung is unveiling a new product today at 4PM BST (8AM PST).
Since February 2018, we've talked about the upcoming Samsung Galaxy Tab S4, but it was only on June 19 that a late Summer launch had become probable. It will be available on Sprint and US Cellular later in Q3 2018.
Competition would heat up in the coming months as new smartphone models were released, it added.
