Hands on: Sony Xperia Z4 Tablet

Can a tablet be too light? Sony's featherweight Xperia Z4 almost made us wonder

Sony’s premium Xperia Z4 Tablet is quite simply the best large Android tablet on the market.

The Sony Xperia Z4 Tablet is sublimely slim, ferociously fast, and offers a cutting edge Android 5.0 Lollipop experience. As an entertainment device, the large screen and enhanced sound make it ideal, and there’s a keyboard attachment for the business crowd. It’s also waterproof, and it has great battery life. This is as close as you get to an iPad on Android.

Sony’s classic industrial design has been polished in the last few iterations of the Xperia line. The hard edges are rounded, but the premium materials remain. The first thing that strikes you about the Xperia Z4 Tablet is just how thin and light it is. At 6.1mm, it can go toe to toe with Apple’s iPad Air 2, but it’s significantly lighter at 389 grams; the iPad Air 2 is 437 grams.

Picking it up one-handed doesn’t represent a challenge, and the light weight is going to make it good for reading, gaming, and watching movies on. But you could almost argue it’s too light. I wouldn’t like to try, but it feels as though you could bend it in half if you took the notion.

The Z4 runs the latest Android 5.0 Lollipop, and Sony exercises a light touch with its user interface. It has also mercifully avoided overloading the tablet with apps. Navigation is smooth, and the 2GHz Qualcomm Snapdragon 810, 64-bit octa-core processor backed by 3GB of RAM clearly offers enough raw power.

Sony really wants to sell this as an entertainment device, and to that end you’ll find a 10.1-inch display with a resolution of 2,560 x 1,600 pixels. It looks great, but it’s difficult to get a sense of how it will perform outdoors, or in the confines of a quiet, dark room when you’re holding it in the bright booth environment of MWC.

There are all sorts of proprietary sound enhancements designed to boost the audio quality of any source and cut out superfluous noise. You’re not going to want to listen to music on it without headphones, but it’s easily good enough for a movie.

Sony is also hoping to court the business audience. It has been working on app partnerships and security, so Microsoft Office for Android is pre-installed, and there’s also a keyboard attachment. Fueling the quality of the experience for business or pleasure is the whopping 6,000mAh battery, which Sony promises will deliver 17 hours of video playback. There’s no scrimping on the storage either. You’ll find 32GB on board, 27GB free out of the box, and there’s a microSD card slot that can take cards up to 128GB in size.

One area Sony hasn’t really improved is the main camera, which is 8.1 megapixels, but the front-facing camera has been bumped up to 5.1 megapixels and it has a wide-angle lens for group selfies. There are all sorts of augmented-reality effects that let you, for example, swap faces or find out how you would look as a cat. It’s undeniably gimmicky, but it can be fun.

Thankfully Sony has retained the waterproofing with an IP65 and IP68 rating. It’s a unique selling point for this tablet, and it’s great if you like to lounge in the bath with something to watch.

As usual, there’s a Wi-Fi-only or an LTE version, but Sony hasn’t released pricing just yet. It would be safe to assume this won’t be cheap.


The Xperia Z4 Tablet could be the best large Android tablet on the market, but that’s partly because it really doesn’t have a lot of strong competition. We’ll bring you a more in-depth look when we get a review unit in.

Samsung Galaxy Z Fold 4 colors: Which should you buy?
Samsung Galaxy Z Fold 4.

The Galaxy Z Fold 4 is Samsung’s latest foldable smartphone, with many useful improvements over its predecessor -- the Samsung Galaxy Z Fold 3. It has Qualcomm’s Snapdragon 8+ Gen 1 SoC, a wider cover display, and better cameras, among others. It’s also one of the first smartphones to ship with Android 12L OS out of the box.

All these spec bumps and design changes make the Galaxy Z Fold 4 a phone worth buying, and as we state in our review, “The Z Fold 4 is really the first time the biggest Samsung folding smartphone can be recommended to most people.”

Someone bought a Galaxy Z Fold 4, and it broke 5 hours later

The Galaxy Z Fold 4 was revealed earlier this month with Samsung promising that it can outlast 200,000 folds, but that wasn't the case for one customer. Posted to Reddit, user u/Merzo1290 shared an image of their brand-new Fold 4 that had broken just five hours after picking it up. According to the poster, they opened the Fold 4 a single time, heard a snap, and saw a devastating crack straight down the middle on the hinge.

The broken Fold 4 was at least able to call a local Samsung support center, so it wasn't entirely useless after the break. As many have echoed in the comments section, this scenario is the fear of every device owner. Luckily, the problem seems to have been identified as an issue regarding defective UTG (ultra-thin glass). While obviously not ideal, fans can take a little bit of comfort in the fact that it's not a new issue for Samsung foldables, so it's easy to identify. And looking at similar reports with the Fold 2 and Fold 3, these incidents are usually only seen with a small minority of devices.

How many folds can the Samsung Galaxy Z Flip 4 survive?

As a potential buyer of the Galaxy Z Flip 4, the biggest concern that customers have before splurging on a foldable phone is the longevity of the folding parts, especially the display and moving parts in the hinge. When Samsung unveiled the Flip 4's predecessor in 2021, the company divulged that it was tested to survive at least 200,000 folding and unfolding cycles. That’s enough for about five years of usage, which is not too shabby.

In August 2022, Samsung dropped its next-generation clamshell foldable phone, the Galaxy Z Flip 4. Even though the Z Flip 4 looks identical to the Z Flip 3, the hinge is a tad slimmer, there’s a faster chip under the hood, and the main rear camera now features larger pixels to deliver brighter and more detailed images. However, if your primary concern is how the Galaxy Z Flip 4 handles folding and unfolding, you can breathe a sigh of relief.
