What are the main flaws? Samsung Fold Z4 Features Review | technology

Samsung has announced its most expensive foldable phone, the Galaxy Z Fold 4, with some minor updates from the previous generation.

But has Samsung won the bet on foldable devices that it started 3 years ago?

To answer this question, we use a report published by TheVerge by author Alison Johnson, in which she spoke at length about her experience with foldable phones.

The author admits that she is not a fan of tablets. Like a large percentage of users, they feel that these devices have no clear place in the ranking, they are too weak to do what a computer does, and too big for normal phone operations.

But with this belief, Johnson found that there is an aspect of Samsung’s vision that could be encouraging for the development of foldable phones that you haven’t seen before, and I found it recently when I saw a small “Galaxy ZFold 4” phone, no need to get up from the couch to get a PC Portable to do work you can’t do on a cell phone.

Is there a difference between this and “ZFold 3”?

The update differs from the previous version of the Galaxy Fold Z3 phone in the use of the latest flagship Qualcomm processor, with better cameras and mainly focusing on the development of foldable screen technology, attention has been paid to reducing the size of the hinge to become better than the previous version.

The author believes that the best thing I noticed in the ZFold 4 – after a week of using the phone – is the external screen of the device, it is only a few millimeters wider, but it is more beautiful in used as the screen in the previous version, which looked more like a remote control. And it’s the device’s external screen that you look at and text hundreds of times a day, so those few millimeters make a difference.

Let’s start with the screens. The hinges and bezels are slightly smaller than those on the Fold 3, giving the 6.2-inch cover screen a bit more room. It has a resolution of 2316 x 904 and an aspect ratio of 23.1:9, which is slightly wider than the 2268 x 832 “Fold 3” display with a ratio of 24.5:9.

The author says she felt a little tight at first from the large size, but after about a day she got used to it. And you see, the keyboard still requires a bit more focus.

The 7.6-inch main display is still the same as last year’s, now with a 2176 x 1812 resolution and a 21.6:18 aspect ratio.

It’s technically smaller than the Fold 3, but you can hardly tell the difference as it’s 8g lighter and 0.2mm thinner.

The author says that when you open the Fold in tablet mode, there’s still a prominent crease on the inner screen, depending on the viewing angle and what’s on the screen, though it’s often not very noticeable.

The camera at the bottom of the screen on the main screen is hidden a little better than previous models, and Samsung rearranged the layer of pixels on top of it to try to hide it better.

The company tweaked some features of the big-screen software on the Fold 4, starting by moving the taskbar from the side of the screen to the bottom so it also runs automatically, a change from the behavior of the sidebar in the Fold 3 .

This is the core of the new phone. Many things a little nicer, but nothing fundamentally better.

Galaxy Fold Z4 features

The Fold 4 also offers more ways to enter split-screen mode to start doing what this phone was built for, multitasking.

With an app open on the home screen, you can still launch split screen by dragging and dropping another app onto the screen. This time you can also start split screen display by swiping from the bottom or sides of the screen with two fingers.

It’s off by default, so you have to enable it in settings, and it works well enough, but the author didn’t find it as useful as the old drag-and-drop method.

You can also make apps always display a multiscreen options button. It’s a small button at the top of an app window that usually appears once you’re in split-screen view. And with the handle always visible, you can just tap it to split the screen or open the current app in a popup.

It didn’t take long to realize the importance of the multi-screen interface for the author, as her entire understanding of the idea of ​​foldable phones changed. She had a list in her mind of tasks she’d rather complete on her laptop than on her phone, such as things that required moving to an email or a browser window or frequently switching between apps.

During her use of the Fold 4, that list got much shorter. She was able to put together a grocery order, compare baby gates she’d like to buy, and even blogged about Fold4 while using it.

The author gave an example of an expense report, where it is usually included in a “to do on a laptop” list because it requires going back into her Starbucks order history and credit card statement.

With the “Fold Z4,” I kept the three apps open on the screen at the same time, and it was a somewhat pleasant experience, according to the author.

Disadvantages of the new phone

The author believes that there is one small problem with the “Galaxy Z Fold 4”, it is the price, which she considers to be big, since the cost of the device is $ 1799, which is almost the same price as the “Fold 3” when it was launched.

Commenting on the high price, she said: “We don’t know how long this design will last 4 or 5 years from now. Spending that much money on a phone is not a good option for most people , even if we leave out concerns about its screen’s long-term durability.”

And there’s the Android platform for tablet apps, where the author had trouble using the phone in multiscreen mode, where the phone apps still span a larger panel instead of the tablet apps. This leaves a lot of empty space unused “and I found myself opening more apps just to use the empty space for something”.

The Fold Z4 is IPX8 rated, which means you can submerge it in fresh water, but it’s not dustproof, which is also a concern. Particles entering the screen via the hinge can create a mess.

The hinge now includes sweeping brushes to try and keep dust out, but it’s hard to say how effective they will be over 3 or 4 years of daily use.

On the surface, there’s a pre-fitted, non-user-replaceable screen protector, and Samsung says it’s using a stronger adhesive this year to hold it in place.

The writer doesn’t find the Fold 4 still thick and bulky when folded, and while it can be used as an everyday phone, it’s heavy and bulky enough that the writer doesn’t prefer it as a daily phone, and says, “I couldn’t discover a comfortable way to watch video hands-free, which seems like something you should be able to do.”

The phone supports the S-Pen stylus and you can use the S-Pen Fold Edition or S-Pen Pro (Samsung)
