Samsung Z400 review

 Review: August 2006  

Last updated June 2009


In a nutshell: The Z400 is the first Samsung phone to feature 3G technology in a slider design.


The slider design has become hugely popular during the past couple of years, so it's nice to see a 3G slider on the market. At first glance the Z400 looks like a silver D500 - slightly wider and longer, but substantially thinner. It's a little heavier than the D500, but nevertheless quite lightweight for a 3G phone.

The Z400 has two cameras: a VGA camera (0.3 megapixels) for video calling and a 2 megapixel CMOS camera for still shots. It's a shame that there's no flash for night-time photography, but in good light the camera delivers good results. The display is high quality with 262k colours and 320 x 240 pixels.

The music player supports a wide range of formats including MP3, WMA and AAC and is stereo. Best results are obtained using a stereo headset - standard or Bluetooth headsets are available as optional extras. The inbuilt speaker is OK but not the best around.

Memory capacity is 30 Mbytes with support for a memory card, but it's a shame that no memory card is supplied as standard. Battery life is poor, and certainly doesn't seem to live up to Samsung's stated standby time of 13 days.

Bonus features include a document viewer with support for common document formats including Word and Excel, and an offline mode for use on an aircraft or to conserve battery life when playing music. Minor gripes with this phone are that when the slide is closed, the display is blank, so you have to open the slide to see the date and time or missed calls. The D500 displayed this information in standby mode, so why can't the Z400? Generally, the Z400 doesn't seem to be as polished as the D500 - the menus are harder to navigate around, the speaker quality is lower, and the battery life is a real problem. The Z400 is a good phone in many ways, but is let down by these issues.

Samsung Z400 features include:

  • 3G video calling
  • 2 megapixel camera with 4x digital zoom
  • VGA video camera (640 x 480 pixels)
  • Display: TFT, 262,144 colours, 240 x 320 pixels
  • Stereo MP3 player (MP3/ACC/ACC+/e-AAC+/WMA)
  • 64 voice polyphonic ringtones / MP3 ringtones
  • Speakerphone
  • Voice memo recorder
  • Messaging: SMS, MMS, email (POP3 / SMTP / IMAP4)
  • T9 predictive text
  • Document viewer (Excel, PowerPoint, Word, HTML and PDF)
  • Calendar, To do list, Scheduler, Clock, Worldtime, Alarm, Timer, Calculator, Currency converter
  • Java games
  • Photo caller ID
  • Offline mode
  • Memory: 30 Mbytes plus MicroSD card slot
  • Connectivity: USB 1.1, Bluetooth
  • WAP 2.0, GPRS Class 10, EDGE
  • Triband plus 3G
  • Size: 97 x 48 x 19 mm
  • Weight: 107g
  • Talktime: 3.7 hours
  • Battery standby: up to 320 hours

I have owned this phone for 3 years and it is as good as the day I bought it. The poor rating it has been given is totally unjustified. ok so you can't set a MP3 for the message alert and it only 1 theme. Messaging IS easy, the camera although not the best does take very good pictures. The menus are not hard to navigate around. All in all a quality phone that you can now buy for about 20 on ebay.

It's good for the first month or so, but then things start to go wrong. It's not very hardy and breaks easily. The screen quality and photo quality is poor. The most annoying thing is it forgets the words you save in predictive text and you can't use mp3s as ringtones. An overly let-down.

Reviewed by compufix from UK on 5th Jul 2008
the battery life is a problem as everyone else said, but by turning 3G off it did help a bit too. All sounds (voice call and txt message) can be modified by going to phone settings - just selet 'edit' from the left bottom conner of the screen. Charging process does seem a bit doggy, now I'm having a problem when I plug in the charger, the phone goes beep-beep, and the screen lights up by itself, you can see the battery indicator froze for a moment, then the charging goes on, and then beep-beep again... I'm not sure if it's because of the parallel-import charger, or a general problem with the model of the phone. Someone might be able to explain to me. ophute@gmail.com

My initial comment was going to be...take this phone and smash it into a million little pieces!! but seriously, I have owned it for 4 days now and have in that time explored opened and tested every single possible feature it has. A few years ago I owned a D500 and that alone prompted me to move away from my recent Sony W810i (Awesome phone) and return to Samsung. The D500 had only 2 annoyances 1) No text message sound options 2) No memory card option but everything else was great, so now we have a memory card option...cool, 2mp camera...cool, Document viewer...cool. Now the downside, document viewer what a joke! you have to manually zoom it one zoom at a time by pressing a soft key and then the zoom button to see the document, and it takes about 6 zooms to be able to read it ha ha nice one Samsung! they have removed the external display clock and missed text/call icons when slide closed WHY! you can no longer reposition the service provider logo and/or change the t ext size and position on screen, they have removed the very useful led light on the camera? so we seem to have the addition of a couple of useful extras and the deletion of a dozen useful ones, maybe the R&D guys at Samsung had their reasons, but in my humble opinion the phone sucks big time now, I hate it and have now got to try my utmost to return it, God I hope I can. Overall a nice looking and reasonable performing cellphone, but the memory card and 2mp cam aside, it is only a tiny improvement over my old D500. I am disappointed and do not intend to keep it. We all have things we look for in a cellphone so you may love it, but for me I love to change my message tones around, and not being able to do that one thing alone really bugs the hell out of me. PLEASE INDULGE ME THIS ONE LAST GRUMBLE. WHY OH WHY DO I HAVE TO SUFFER MY BOUGHT FOR CASH CELLPHONES HAVING VODAFONE LOGOS PLASTERED ALL OVER THEM !!!!!! I WANT PAYING IF I HAVE ADVERTISE THEIR NAME ALL OVER MY PROPERTY. THANKS FOR READING.

I think this phone is terrific.I don't understand everyone elses whinging. Honestly if you're looking for a good, sturdy, reliable phone, then this is it. With normal, everyday use (camera, calling, texting), the battery lasts between 3-4 days; excellent if you ask me! And the volume is just fine, I assure you. It has the loudest ringtone I've had in my experience. The camera is absolutely EXCELLENT quality. A shot in semi-light was still good enough quality to get it printed at the photo shop. Also, the screen is clear, and the buttons are easy to use: perfect for someone older or technologically challenged. I would reccommend this phone to anyone.

Reviewed by Dan from stoke from UK on 27th Jan 2008
Ive had this phone for well over a year now n i really am sick of it. First disappointment is the sound, its very quiet so not very good when you want to listen to music. Another fault has to be that there is no flash on the camera so is pretty useless for taking it for a night out. As a lot of other reviews have said the battery life is very poor, i believe it lasted about 30 hours or so the other day so this is a phone to avoid.

Unfortunately the lowest star rating you can give this phone is 1 (otherwise it would have been 0). I have had this phone for 6 months and there has been nothing but problems. I have had to replace 2 charges due the phone and charging over heating. In the past week alone I have had to have the battery replaced and a new handset. When the handset arrived, again the phone wouldn't charge (surprise). Upgraded from Sony Ericsson K750i and this was the biggest mistake I could have made. If you have any sense about you, you will stay clear from the Samsung Z400.

I got this phone as an upgrade from an earlier Samsung. I would echo the main review. There is much to admire about the phone but it lacks some polish - one gets the feeling it was rushed out onto the market. The biggest let down is the battery life which on my phone is dismal. I have ordered a replacement (sourcing of which was difficult) because I can not believe the battery I have can be functioning fully.

The battery life is pathetic in 3G areas, (although it does improve when not in 3G, or when it is disabled) and the phone finds very inconvenient times during the day to suddenly run out of battery(even though i charge it every night). And to top it all off the other day i plugged it in to charge and it just died. Totally bricked. Wont switch on, wont accept a charge.

I have had my Z400v for a week now. My first impressions were good. However a few annoying things have become apparent. Firstly < I cant install Java applications that I had stored on my PC. After reading comments on the internet, it seems that the phone is programmed exclusively for Vodafone, hence the "v". Not a major issue for me. Also the battery life is not as good as it could be. I have also found that if I transfer files to the memory card and then later I want to transfer the files back to the phone's memory, they seem to disappear into a black hole. I still think it is a good general purpose phone, but I would rate it 8 out of 10.

Just wish there was a clock and message indicator when its on standby and not just a blank screen, however, if you just press a button, it uses up less energy than sliding the phone open and turning the brighter light on. I seem to keep getting really loud robotic screaching midway through calls if the reception isn't good. Pretty damn annoying!

I upgraded my D500 for this one. I was very happy with my D500, and chose the Z400 because it seemed to be quite similar. It is pretty simple to use, looks nice, and the camera itself is quite good. If I had the choice again, I would avoid this phone completely, purely based on the awful, awful battery life. You really can't rely on it at all.

i have had problems with this phone. i am about to have the phone replaced for the 3rd time. I have had problems with it switching itself on and off whilst several metres away from me and also being unable to switch it on and off with the button- having to remove the battery instead. whilst i did like the phone when i got it, these problems have meant that i think the phone is infact pretty poor. if it had only been one phone that had gone wrong i would have throught it was nothing, but more than one makes me think there is something wrong with the actual model. also the battery life is really poor. i would not recommend the phone to anyone considering it

its absolute rubbish, the battery lasts as long as a candle in the wind!! i have had a replacement battery, a replacement phone and more recently a new replacement handset and battery and it still only lasts a max of one and a half days. DO NOT BUY IF YOU WANT TO USE YOUR PHONE AS IT NEVER LASTS. Highly recommened if you like to leave your phone at home and not use it.

This is the worst phone i have ever had. The signal quality is shocking the battery life is appalling and the inbuilt speaker is not worth having. The headphones that came with the phone for hands fre use broke within a week.

I am quite disappointed with the battery life as I need to charge it almost everynight dispite of average usage. It also take many steps to get to the speakerphone when I tried to use it for an incoming call while driving. Why can they do a one step key that allows calls to be diverted to the speaker phone. I think most motorist would appreciate it. I also tried the recorder and to my horror it cant record telephone conversation. so if someone tries to tell you information over the phone you have to go back to pen and paper! :(

i like the phone - but i am a little disappointed. i did have the D500 before this one - and i feel that they have taken away many things that was good about the D500. i have only had the phone a week and already missing the stopwatch, camera flash and infrared. also, they have made all the functions more complicated. it is too much hassle to send a message now - you have to confirm the message about 3 times before you can send it off. i think the D500 is a much better phone and i am considering going back to that one..... also - to add to my point before - the volume on this phone is pathetic. i miss every phonecall and hear messages way after they have been sent. the message tones and slide tones were much better on the D500

Don't bother buying this phone. I have been using it for 6 months now and have missed so many calls because the ringtone is to low or it loses the signal when everbody around me has a full signal. if you want to everyday have to call people back then this is the phone for you. Stay clear

It's quite a good phone and does what I want it to, but complaints are the battery and the reception. I work on the London Underground and when I come back above ground it does not always find a signal and stays in "searching" mode. Very annoying and the only way you can get reception is ti turn it off and on again and let it reboot. The number of times people have tried to ring me and not been able to because of this is countless. My Motorola V3 never had this problem.

I've had this phone since last August, I agree the battery life is horrendous... but mine has just decided to pack in... I try to turn it on and the screen stays black (it lights up but no picture shows)... will have to take it into Orange but a real inconvenience. I hate this phone!!
