Just last week, if you asked me which is the best flip phone to buy in 2024, I would have probably pointed you to the Motorola Razr Plus (2024).
Motorola's new clamshell scores a lot of extra points for style, and it has bigger screens than the Galaxy Flip series, plus it offers faster charging and an impressive amount of accessories for free in the box.
But after spending some time with the Galaxy Z Flip 6, I have now changed my mind, and this change has everything to do with one improvement I did not expect would matter that much.
And it's the screen.
Galaxy Z Flip 6: up to $650 off with a trade-in
Get the Galaxy Z Flip 6 at the official Samsung store, and you can save up to $650 on the newly released clamshell phone with eligible phone trade-ins. Alternatively, get it via the Samsung Shop app at $150 off before trade-ins.
The Flip 6 might have a smaller cover screen and a smaller main screen, and it might have a crease that is more noticeable than the one on the Razr Plus, but all of that does not matter as much as one fundamental feature: brightness!
The Flip 6 gets dramatically brighter and colors on it look impressively vibrant and juicy, even when you take it under the bright sun on a hot summer day. And that remains a very important use case.

In comparison, the display on the Motorola Razr Plus (2024) looks faint and dull in the same conditions, while previous Galaxy phones like the Flip 5 and even Galaxy S24 both overheated in a matter of moments and their brightness plummeted.
The Flip 6 also has a brighter outer screen
The Flip 6 remained extra bright for far longer, unbothered by the heat. After all, it is the screen that you are interacting with all the time, it's a fundamental component of the smartphone experience, so seeing that in person was a mind shift moment for me.
We have also run our in-depth display testing here in the lab, to try to put this experience into numbers, and these are the results we get.
The CIE 1931 xy color gamut chart represents the set(area)of colors that a display can reproduce,with the sRGB colorspace(the highlighted triangle)serving as reference.The chart also provides a visual representation of a display's color accuracy. The small squares across the boundaries of the triangle are the reference points for the various colors, while the small dots are the actual measurements. Ideally, each dot should be positioned on top of its respective square. The 'x:CIE31' and 'y:CIE31' values in the table below the chart indicate the position of each measurement on the chart. 'Y' shows the luminance (in nits) of each measured color, while 'Target Y' is the desired luminance level for that color. Finally, 'ΔE 2000' is the Delta E value of the measured color. Delta E values of below 2 are ideal.
The Color accuracy chart gives an idea of how close a display's measured colors are to their referential values. The first line holds the measured (actual) colors, while the second line holds the reference (target) colors. The closer the actual colors are to the target ones, the better.
The Grayscale accuracy chart shows whether a display has a correct white balance(balance between red,green and blue)across different levels of grey(from dark to bright).The closer the Actual colors are to the Target ones,the better.
Notice that we test the brightness level at 100% white, while official numbers from Samsung typically give a higher value tested at just 1% or 5% white level (effectively, a tiny white spot). So that is why the number we get is lower than the official 2,600 nits that Samsung quotes.

But as you can see, the Flip 6 is a huge improvement over both the Flip 5.
Interestingly, in the lab, the Motorola Razr Plus (2024) scores on par with the Flip 6, but out in the sun, it was noticeably dimmer.
We have our full Galaxy Z Flip 6 review in the works and we will be investigating more about this and, of course, telling you a lot more about this superstar flip phone very soon, but we wanted to share this important tid-bit right away. Make sure to check back early next week for our final review.
