I have had this phone for a few days now and I can say without any reservation it's the coolest and most amazing piece of technology I've ever owned and played with. I build my own high end gaming computers and had a s10 5g before this so I'm definitely an enthusiast. Reviewers are over playing how fragile this phone is for drama points. It's a very solid phone with obvious fragility due to the inherent nature of a bendable material. Pros: -the screen is stunning, even compared to my s10 5g. -the battery life is great, playing videos all day. -the hinge is solid and easy to open and close but requires deliberate intent. -the small screen is amazing for one handed and quick use, I use it all the time to text and check things quick. -video and sound quality are amazing. -customization and multi task options are outstanding. -the cameras and flashlight are best if the best. -the wear buds it comes with are phenomenal. -when you take into account this product is a 3 for 1 purchase, phone+tablet+wireless headphones, it's actually not that expensive. -it's literally the most convenient mobile entertainment package you can buy right now -huge storage and very fast hardware. -it WILL NOT effect your credit cards, keys, or scan fobs. I've had the phone next to my credit cards and gym scan fob in the same pocket for days. I also had the Moto Z which had just as strong of magnets. Beware of hotel room keys though, my Moto Z would mess those up. Cons: -this phone is very hard to find -the case it comes with is basically just for looks because it offers zero impact cushion and doesn't protrude past the rear camera bezel.. I had to find 3d stickers to keep the lenses from touching a table surface if you place the phone down. A must. Waiting for an impact case on order. -unproven track record, unknown lifespan and durability over the long term as it's a first gen first of it's kind product. Overall, this is an absolutely incredible first edition of a folding phone and I would recommend it to anyone without hesitation as long as they understand the inherent characteristics of the design which make it not as rugged as a solid state device. This phone and the screen do not seem FRAGILE, but it is not rugged and tough so you have to be conscious of that. HIGHLY RECOMMENDED.

I have had this amazing device for 2 weeks now, and I have to say that it is, hands down, the best cell phone I have ever had. The reason behind this is because it is a tablet as well. While the price may seem high, it is actually a good deal for what your get. I had an S7 and Surface 3 prior to getting this phone and my Fold easily replaces both devices. I purchased a Geyes folding Bluetooth keyboard on Amazon and use the USB adapter to create a computer set up with the Fold. It is fast and very functional. The device feels nice a weighty in my hands, the small screen is great for quick checks and messaging. When closed, it actually feels like a cordless home phone due to it being narrow. It feels much more comfortable in the hand when closed. I use the SwiftKey Keyboard as I find it's predictions and key placement are better than the Samsung stock keyboard. My hands are large enough that a full keyboard feels better on the inside 7.3 screen and the split Samsung keyboard is counter productive for me. The colors are amazing on both screens. One thing I found interesting is that you basically get 2 phones in one with the Fold since the home screen layouts are different on the 4.6 and 7.3 screens allowing me to place widgets, apps, and app groups in different places on both screens to maximize my productivity. You do have to be more conscious when wielding this phone as it is not water proof, dust proof, and definitely has the potential of allowing small elements in. For instance, I do not take the phone out of my pocket when going in the sauna at my gym. I make sure very few people handle it. I educate those who do on the potential weak points and demonstrate how I want them to handle/open and close the screen. I do not apply too much pressure on the big screen. I actually treat it like a normal screen, but know that it is not as strong. The crease doesn't bother me, I can see it, and I actually feel like seeing, feeling, and knowing it is there is good as it reminds me that this screen is and can be fragile and I should handle it with care. It is an amazing talking piece as I am the only one in my County that has one. People are amazed when I open it up. Samsung really hit the nail on the head with this device. I definitely think it will only get better, and bigger. I am very happy with my purchase!!!

At the time of this writing, I've been using this product for about a week and a half now, and it probably is the most practical or useful product I've used. It is not the "best" or "most amazing". It fulfills the needs of having a phone and tablet at the same time, whenever and wherever I need it. I acknowledged the risks before purchase, and I was able to enjoy the features without much worrying. Think of it as a foldable mini iPad with minimalist bezels, that turns into a candybar-esque phone with an iPhone 4S screen when closed. Reading or viewing content on the larger, inner display is a delight. It's still AMOLED, and with Samsung's vivid color mode enabled, it makes you appreciate the form factor / screen even more. Playing games is fun too, and with a folding hinge it's almost like a Nintendo DS in some cases. Speaking of cases, it comes with the Aramid Fiber one in the box, which supposedly does nothing for drops, but will protect against scratches or scuffs. Admittedly, I did drop the phone from waist height unto a hard carpeted surface (ONCE!) but I haven't noticed any damage or issues. Maybe it does help? The 'phone' doesn't have any IP Ratings either, so I have been more cautious, but daily activities don't seem to cause any issues so far. In regards to the crease, I really can't notice it. I mean, yes, I notice it when I am looking at the screen from an unhumanly angle or trying to show someone else the phone. When looking at it in typical indoor lighting, dead-on like a normal human, or even when viewing certain content (even from an angle) the crease suddenly... disappears from sight. It's really weird knowing that the crease is supposed to be there, even when you've seen it so many times in youtube videos, but it just goes away. Hard to explain until you've used the phone yourself. Everyone I've shown or let handle the device so far has said the same thing. Can faintly feel, but when using it and looking at it like you would any other device, the crease becomes less noticeable or goes away from sight. To this date, whipping out the phone in public or office spaces garners much surprise and many hilariously shocked reactions from my obvious, intentional flexing (pun intended). #myphonedoesntbreakwhenfolded

Don't let the negative press of the first batch of these deter you. This phone is nowhere near as fragile as most make it to be. Granted, I have kept mine in a sturdy case since the day I got it. Yet, it has taken numerous falls and abuse from toddlers without breaking or losing any functionality. Something I can not say about iPhone, which seem to break from the smallest of falls even with a case (in my experience). The screen unfolded is massive and gorgeous. Never have videos and images looked so crisp in a mobile format. Can truly rival any normal tablet. I also rather enjoy that the unfolded screen in not made of the typical glass most phone screens are. As it has less glare and is more enjoyable to scroll and type on. The exterior screen is the biggest con of this phone. As it is simply too small for me to accurately type. However, it is perfect for quickly changing songs, looking at notifications, and taking quick snaps without worrying about trying to unfold it in time. The cameras on this phone are incredible. You will not be disappointed in the quality of your phones. And having the speakers on both ends of the phone allow it to have audio separation while watching videos and a big volume boost compared to other phones. Very nice feature rich phone. Also comes with galaxy buds as a nice bonus to make up for the lack of a headphone jack and the high price. Well worth every dollar.

First, I would like to pay my respect to Samsung's engineers. We always take new technology for granted...And we always forget to thank the people who work hard, day and night, to make our lives easier and more productive. So hats off Samsung Engineers. 3 things make me fall in love with this phone: 1- Multitasking: I'm a business owner, and I run a credit card transactions all day. To run a credit card transactions, I need to open a tab for the credit card app, a tab for the calculator, and a tab for chatting with the employees. With the Fold, I've been able to do all that on one page, and in bigger sizes. 2- 7.3 inch display and App Continuity : Most of us use our phones to check Instagram, Facebook, and other social network apps. To be able to see the pictures and videos of our friends and families that big on a phone like the Fold, It's literally the big picture :) 3- Travel light, and a better Netflix companion: I used to drag my heavy laptop or my big tablet every time I have to fly from Detroit to Dallas or vice versa. With the small spaces a planes provide these days, the fold is the perfect companion. Now I can make phone calls, comfortably check my emails, and watch Netflix movies on a bigger screen, in a light weight, and in an impressive portability. All that in one device that I can carry in my pocket...and without the need to bring more heavy weight devices on the plane. Bottom line, this phone is futuristic, innovative, and practical. I was little bit frustrated to wait for this phone for almost 6 months after I originally pre ordered it from Samsung on 4/14/2019. However, it was worth the wait. Thanks Samsung, and thanks Samsung Engineers.

[This review was collected as part of a promotion.] I originally purchased this for work - spreadsheet and website based ticketing. But the larger view for maps and and desktop work was exactly what I needed. The larger view is so much easier on my eyes and it's nice to have a slimmer closed size screen so I can text one handed again. It's the best of both worlds. Of course the larger view for webbrowsing, games and movies have been enough to convince some friends and family to even switch from their iPhones just to get this model. Mine is an unlocked 1 TB model used on T-Mobile.

[This review was collected as part of a promotion.] I pre ordered the burgundy version of Z fold 4 and traded in my S22 Ultra for a great deal. I have owned many generations of galaxy devices since past 7 years because of their great value and latest features but I was blown away with the foldable tech. Experience of main screen for video content and games is really amazing and immersive, not to mention typing feels really natural and comfortable as fold is really light compared to what it offers. Flex mode is really cool especially for reading comments along with YT video or taking group photos by placing phone over a flat surface. Crease and under screen camera becomes invisible in matter of few seconds. Cover screen is decent for on the go phone experience and overall hinge mechanism feels very reliable. After using it just for a month, normal phone experiences are ruined for me. I hope in next generation they can offer slightly wider cover display and spen slot in the body itself. That would make z series perfect for me in every way.

fantastic phone! no issues with dust under screen as reviewers talked about. i haven't used my tablet since i got it. will definitely want the next version as long as it opens into a tablet like this and front screen is still as functional when closed. price is a little high but i would buy it all over again!
