Fits in with your style
Say goodbye to planning your outfits so you can fit in your phone. Galaxy Z Flip4 is a compact full-sized smartphone, even when folded, and just the right size to slip into a pocket when its time to play.
Withstands drips and drops
These are the worlds first water-resistant foldable smartphones. Our toughest aluminium frame made with Armour Aluminium and our exclusive Corning® Gorilla® Glass Victus®+ makes these our toughest foldables ever. And the 6.7-inch display unfolds a beautiful view with Ultra Thin Glass.
Flex into epic photography
Say hello to a versatile, hands-free camera experience. FlexCam lets you take advantage of your phones agile angles so you can snap group shots, selfies and videos from mind-blowing perspectives and impressive true-to-life detail — even in your go-to social apps.
Power to the pocket
Let every call go into overtime. An upgraded 4nm processor works with a long-lasting 3700mAh (typical) battery to power through the hours. When it's low, plug in for Super Fast Charging or bypass the cord with Fast Wireless Charging 2.0. Share that charge with a friend with Wireless PowerShare.
The window to your world
The 1.9-inch Cover Screen gives you yet another creative canvas. Personalise the clock face with your videos, photos or AR emoji. It can easily update with your mood or your outfits. Access Quick Settings, reply to texts and add widgets to keep apps at your fingertips — no Main Screen necessary.
Better rest is all in the wrist
Checking up on yourself just got easier. Track your sleep patterns right from your wrist with Galaxy Watch5 making note of your sleep patterns and more. Once it gets to know you, you can find out your sleep animal and get useful tips to help you make the most of your downtime.
Old phone, meet new phone
Smart Switch makes the transition between your phone and Galaxy Z Flip4 simple — even if you don't already have a Samsung Galaxy. In just a few steps it brings over your photos, texts, data and more.
