Welcome to sotophone's early Samsung Galaxy Z Flip review. A new Samsung Galaxy folding phone had been rumoured for a while – ever since the original Samsung Galaxy Fold was launched, in fact. 


SAMSUNG GALAXY Z FLIP REVIEW: DESIGN 


The first thing we need to talk about in this Samsung Galaxy Z Flip review is the folding mechanism. The Samsung Galaxy Fold was notoriously brittle, with problems and the phone’s fragility causing a staggered release date. The Samsung Galaxy Z Flip has taken steps to prevent this, using a “hideaway hinge” to seal the vital components away from dust and grime. It’s claimed to be built to last and it certainly doesn’t feel flimsy to open and close, with the screen able to fold over 200,000 times without issue. In one of the coolest twists of the phone’s folding design, the hinge works like a laptop rather than switching between “open” and “shut”. Called “flex mode” by Samsung, the freestop hinge splits the screen, allowing you to keep watching a video and post a comment simultaneously, or use the phone as a free-standing camera. It feels robust and stable on handling it. However, as you might expect, beyond a certain angle and the screen naturally falls into “closed” or “open” mode depending on which way the screen tilts. The external 1.1” display provides connection even in closed mode: calls, alarms, times and notifications are displayed on the slender screen. All of this, of course, is remarkably reminiscent of a retro flip-phone, which would show calls and texts on the closed LCD screen. It’s a neat nod to the past without relying on it, a la the Motorola RazrAway from the mechanics, the phone is compact, with a large 6.7” screen folding down to a wallet-sized soft-cornered square. Those rumours regarding the inspiration of the phone being folding make-up cases were right on the money, but it also reminds us strongly of an old GameBoy Advance SP. Coming in three colourways: mirror purple, mirror black and in certain countries mirror gold, all three colourways are designed to catch light. Great for showing off to your mates, but less so for being discreet in dodgy neighbourhoods. 


 


SAMSUNG GALAXY Z FLIP REVIEW: CAMERA 


 Although Samsung Galaxy Z Flip comes equipped with a punch-hole 10MP selfie camera, it’s the 12MP rear cameras with up to 8x digital zoom you’ll be using most often, as you can snap selfies with them in closed mode. In a neat twist, the external one-inch display can be used like a viewfinder, allowing you to position the camera accurately while the phone is closed. It’s actually very simple to use: tap the power button twice in closed mode to open the viewfinder, and the volume button once to snap the pic. When in flex mode, the Samsung Galaxy Z Flip is one of the first phones with its own free-standing mechanism. Leave it on the table for an hour (but don’t leave it unattended, obvs) and take a time-lapse of a sunset, for example. It’s a neat trick that uses the folding function as more than novelty, but the cameras inevitably don’t pack the punch of the Samsung Galaxy S20, which is built around its much-lauded 64MP cameras mounted on that impressive rectangular module. While our brief look at what the Z Flip cameras are capable of was impressive, the majority of our experience was centred around the folding function. Time will tell whether the cameras can hold up side-by-side with other popular phones in its price bracket, although it obviously doesn't have the impressive capabilities of the iPhone 11 Pro or S20 Ultra.


SAMSUNG GALAXY Z FLIP REVIEW: SPECS


The Samsung Galaxy Z Flip has compromised its innards in some respects, but retains a higher-end 7㎚ 64-bit Octa-Core Processor to keep pace with other phones in the same price bracket. With 8GB of RAM and 256GB of internal storage, it’s no slouch in the memory department, but there’s no SD card option to extend that memory further. A 3,300mAh battery keeps everything ticking over. It’s not as powerful as other flagship batteries, but compromises have to be made. Wireless charging and power-share capabilites come as standard, which is some consolation, but we didn’t have time to rigorously test those functions yet.
