Samsung U100 review

 Review: June 2007  

Rating: 4 stars

In a nutshell: Wow! The U100 is the slimmest and lightest phone ever. Put this phone in your bag or pocket and watch it disappear!



The U100 is the second of Samsung's second-generation Ultra phones to arrive in the UK and is the replacement for the Samsung X820. The U100 replaces the X820 as the thinnest phone in the world! The U100 shaves 1mm off the already skinny X820, measuring an astonishing 5.9mm thin. At the same time, the U100 is a narrower phone, and this is a welcome improvement, as it makes the keypad easier to use, especially for people with smaller hands. But Samsung weren't content just to make this the world's slimmest phone - it's also the lightest. At just 57g it weighs about half as much as a typical mobile. Really, when you put this phone in your jeans or shirt pocket, you're going to forget that it's there! The U100 is the ultimate for anyone who prefers their gadgets miniaturised!

The X820 was a popular phone, but never as popular as the slide-design D900, and we expect that the U100 won't match the huge popularity of the U600 slide phone either. That's partly because slide phones are the "in" look of the moment, but also because the U100 misses out on several of the features of the U600. We'll compare the U100 with the U600 in a minute, but first let's take a look at what the U100 has to offer.

The first thing that you notice once you've got over just how thin and lightweight it is, is the neatness of the design. The keypad is small, but easy to use and the phone is very ergonomic. However, if you've got large hands you might find it just a bit too small for comfort. The LCD display is a bright TFT display, the same as used on the X820. It isn't the biggest screen around, for obvious reasons in a phone this compact, but it's perfect for the size of the phone. Samsung's new black & white user interface is easy to use and very smart in appearance. If you're just using the phone for talking and texting, you'll find it very easy to use.

When you spend £200 on a phone you expect it to have more to offer than just its size, and the U100 has plenty up its sleeve. Despite its tiny size, it comes with a 3.2 megapixel camera, which takes pretty good pictures, and records high quality video clips too. However, just like the X820 the U100 has no flash or autofocus, so its not going to replace a dedicated digital camera. Likewise, the phone comes with a high quality MP3 player that supports a wide range of music formats (MP3, AAC, AAC+, e-AAC+ & WMA) and delivers good quality audio using a Bang & Olufsen digital power amp. However, it won't ever replace your iPod because the memory of the U100 is limited to 60 Mbytes (enough for around 15 songs) with no option to add a memory card.

The U100 has good connectivity options, with support for wireless Bluetooth 2.1 and a fast USB 2.0 port. It also has a TV-Out connection which enables you to watch your videos or photos directly on a TV. It can handle all kinds of messaging, including email, has a fast EDGE connection to the internet, can browse web pages at a push, and has the usual range of personal organiser functions that you'd expect from a modern mobile. Battery power is something that's definitely of interest with the U100, since its predecessor the X820 had fairly poor battery life. The U100 incorporates Samsung's new OPUS (Optimized Power Usage Solution) technology that is designed to get better performance out of a smaller battery, and initial impressions are that battery life is OK.

It's perhaps not fair to compare the U100 with the U600 slide phone, since the U100 is so much smaller. But we're going to, because if you're considering buying the U100 it's an obvious question. The key thing to understand is that it's not a fair comparison: the U100 is half the size of the U600, so you just can't expect it to do as much. The point of the U100 is that's it's the smallest & the lightest. If you want a phone that will simply disappear into your pocket or handbag and that will gently wow you every time you pick it up, then the U100's your phone. If you want more power from your phone, choose the U600. The U600 has a larger, higher resolution screen; it has a camera with autofocus and a flash; crucially it has a memory card so you can store lots more music and videos; and it's quad band too. Although the U100 has a camera and a music player, they're just there for fun. Understand this and you'll be the happy owner of the world's thinnest mobile!

GOOD: thinnest phone in world. Turns heads. Taking off my trousers and forgetting it was in the pockets became a regular occurrence. Nice feel to the keypad - like one button. Great camera for such a thin phone. BAD: One thing that everyone seems to have skipped over is the fact that the dimensions advertised everywhere (including here and even on the samsung website) are WRONG. The phone is 115mm long - a full 10mm longer than advertised. This annoyed me a lot. Other annoyances are that when you type in a number it auto selects a recent similar number you have rang (bit like predictive text) and it takes another button press to over-rule this which means if you are quickly typing in a number, you often get it wrong as one of the numbers you type in will have been used as the overrule keypress for the predicted number. I couldn't find a way to disable this. The keypad, although aesthetically pleasing is less than practical for those with larger fingers. The battery life is atrocious. Must charge every night without fail. Mine finally gave up the ghost when moving house. The screen got a strange under-surface crack in it either by snapping in my pocket or by bleach getting in it. But this was well after 2 years of reliable use. Shame cos I liked having the thinnest phone in the world.

Had this phone for a year. It replaced my X820 which I snapped by sitting down with it in my (front) trouser pocket. I've found it just as good as the X820, however I only use the phone, camera and movie/music player functions. My only negatives are that the screen has started to 'bloom' at the bottom and that the battery cover is becoming prone to sliding open on its' own. Am looking for a replacement but haven't found anything comparable yet - even the U800 is 9.5mm.

i dont have any idea why people can write a bad review about this phone. This is the best phone (in the "phone that as features i really use" category) iv had for a very long time. I have a HTC PDA as a pro phone and this as a personal phone. ʹve had hundreds of cells (mainly nokias (the latest a 6120 classic 3.5 g phone got so hot in a call that almoust melted) and i can say, 100% error free, this is a very good phone. It looks great, its works great, the batt lasts 5 days in normal use, the sound is great, the camera is great, the thickness is amazing (a no noticeble pocket object). The only (really only ) downsize is the lack of a mem card slot! no doubt att all!!!!!!!!!!!!!!!!!!!

Great phone. So slim and lite that it into the fold of your wallet. You can take it to the pub or club and you won't feel burdened by it. Sound quality is very good. The camera is great in the daylight, as is the video. Has some great features, like bluetooth, mp4, mp3 multiple alarms(x5), flight mode, converter, stopwatch, voice recoder, speakerphone, image editor, world clock feature, timer, memo, notes, calculator, games and a web browser. The phone is strong and won't break easily. The screen produces great vivid colours. It's a very good phone and makes a wonderful change from the Nokia "smartphones" with that terribly slow and buggy Symbian OS. It's cheap as well. I got mine new on eBay for AU$150. Grab one. You'll love it. Promise.

G'day folks. I left a review a few days ago about this phone(U-100). Well, the phone is dead. I was transferring an MP3 file via Bluetooth to the phone and the slimmest phone in the world seized up and wouldn't respond. I removed and replaced the battery to reboot the phone but it now only gets to the startup screen and seizes up completely again. Perhaps I overheated the Bluetooth chip(if there is such a thing). Who knows. Anyway, maybe I shouldn't have recommended this phone. It looks good but perhaps they forgot to allow for adequate cooling of the chips. Amazingly thin, but that's all it is.

Great phone. Had it for a week. Good battery life. Screen produces great colours. Camera is excellent in the daylight. Video is not to bad either. Posted example on YouTube: youtube.com/watch?v=LWbdugz_Mgo Keypad is good. Keys are tactile. Only complaint about the keypad is that the center menu key launches the browser and thisThe ccan't be changed. This is a bit of a pain when you press it accidentally. Call clarity is superb and reception is excellent. Great little phone. Grab one if you can.

This is my personal view only as I think this phone is a revolution in design for the style conscious. My previous phone was the X820 which is still a wonderful phone, it will be set aside but will never make the exchange route or bin. While using mine I noticed it seemed like no one had ever seen one of these really slim phones. I was constantly looked at if I ever got this thin phone out to use. Many a time I would get requests to have a look at it. That speak for itself. I however dis-agreed with the comments about the phones camera (at 2 megs on the X820)as I found the camera a dream when down loaded to my Sony laptop. The new U100 now comes with a 3meg camera and I can not wait to see the results when downloaded to my laptop. My hands are far from small and have not had any problems with using the keypads on either phone - new model or old. So it goes to show that not all reviews are going to be spot on? The main reason I opted for the X820 and now the U100 is the fact it is so small it can be hidden away in your top pocket and no one need know you have a phone. Keep it on silent and a little discretion will always keep it that way. The features of the phone are many and its a really great "smallest phone in the world" to own. I have been awaiting this day when camera and phone unite as one in the top pocket. When these phones get to 10 meg we can all dispose of the digital camera. Well in fact mine hardly ever comes out now - there really is no need. Ok may in the night after the sun has set. Never mind any negatives you might read they are all over come by the shear beauty of this phone - it is like no other in its class. Functionally it is the same as most of the phones out there. Its a little like to Nokia's key pad, you get use to the functions and so on and it grows on you. This phone is unlike a Nokia functionality but I do like it. May be the difference with most reviews to this one is I have been using the phone every day for a year (X820) and the new U100 performs just as good, whereas most reviews only play with them for a limited number of days even hours. You make up your mind by purchasing one - you will be converted but please do not tell everyone as it won't be such an exclusive gadget any more!

excellent phone in general. I was looking for an ultra thin mobile that would disappear into my trouser's, which this unit does quite well. The only negative is that i find i drop alot of call's with this mobile, this is probally due to the fact that it is a tri band, and not a quad band. I would recommend this phone for it's ultra thin design and appearance. However i will probally upgrade to the sony t650i once it is realeased.
