Samsung Galaxy Z Fold 4 Overview:
Design & Build
The Fold 3 was Samsung’s big push in terms of creating durable foldables. From IPX8 water resistance to Armor Aluminum hinge, stylus support, and an 80% tougher main display, it had it all. Not all, exactly. It still lacked dust ingress protection and above all, the phone weighed a lot heavier than a typical slab smartphone.And unlike how Samsung had to cut the battery size to reduce the weight coming from Fold 2 to Fold 3, this guy doesn’t make the same sacrifice. Instead, you can thank the new slimmer, rotational hinge mechanism for this. The company had been using a gear-based structure for all its previous Galaxy Z Fold devices. But the new single hinge mechanism not only makes way for a lighter phone but also thinner foldables.
Display
Despite the slightly modified dimensions, the Fold 4’s display sizes have remained the same. Both on the front and inside, but with a lot slimmer bezels. Its cover display is a 6.2″ HD+ unit while you’re greeted with a 7.6″ QXGA screen inside.
Samsung has used a Dynamic AMOLED 2X panel on both sides with a 120Hz adaptive refresh rate. But like last year, only the main display features LTPO backplane technology to enable switching the refresh rate between 1 and 120Hz.
Samsung also says it has optimized the layer structure to help reduce external shock damage on the main display. The crease has also undergone some minor readjustment with a new enhanced adhesive on the PET screen protector and whatnot. It’s now visibly less prominent compared to Fold 3, but still not on the same level as what OPPO’s foldables manage.
Performance
When it comes to performance, the Fold 4 brings your usual chipset upgrade. Now powered by Qualcomm’s 2022 mid-year refresh, the Snapdragon 8+ Gen 1. Based on TSMC’s 4nm process node, this chip reportedly delivers excellent power efficiency which should result in better battery endurance here. Complementing the 8+ Gen 1 is 12GB LPDDR5 RAM and 256GB to 1TB of UFS 3.1 internal storage.
But the biggest upgrade we were expecting that didn’t come to fruition is definitely the price drop. Even though the pre-order and trade-in offers are ridiculously lucrative in the western parts of the world, the price of Samsung Galaxy Z Fold 4 in countries and Nepal, unfortunately, won’t go down much compared to Fold 3.
Besides the chipset upgrade, Samsung has introduced some really cool software features as well. First off, the phone runs on Android 12L-based One UI 4.1.1. The One UI 5 (Android 13) update is already available for the Fold 4, by the way. Intended specifically for large screen and foldable devices, this version of Android introduces some helpful multitasking features including a PC-like “Taskbar” on the bottom part of the main display.
Gestures are now swifter, switching between apps is more intuitive, while a handful of apps like Facebook, TikTok, Gmail, Chrome, Microsoft Office, and Outlook have also been better optimized to make the most of the main display. And like Samsung’s other flagship devices, the Galaxy Z Fold 4 will get 4 generations of OS and 5 years of security updates too.
Cameras
Cameras see a healthy upgrade as well, although in the same layout as before. But I’m not complaining! Samsung has replaced the 12MP trio in the last two generations of Fold devices this time with a 50MP wide, a 12MP ultrawide, and a 10MP telephoto camera with 3x optical and 30x Space Zoom this time. Oh, and the wide and telephoto sensors are optically stabled too.
On the other hand, the 10MP camera on the cover display has remained the same. But according to Samsung, the second-gen 4MP under-display camera (UDC) on the main display now uses a scatter-type sub-pixel arrangement which should help it stay a lot less noticeable compared to the one on the Fold 3. 40% denser pixel density, claims Samsung.
Apart from hardware upgrades, there are also a few cool computational photography stuff to look out for. This includes Nightography for better low-light images, a larger zoom map on Capture View Mode, Dual Preview, and more.
