The recordings at the Blue Earth can be described as really good, because the play is very natural and there is dynamic sound. Also noise or scratching can be heard in the background, barely.

    11. E-mail functionality - Connection type: POP3, IMAP4 and SMTP. Setting the e-mail accounts is done in a few steps. However, the types of servers have to be entered by hand and can not be downloaded automatically, as many another mobile phones. Retrieving emails can be done very fast. Annexes are also after a short download time, immaculately presented, if they are not too large.

The notes function possess only 100 characters and does not scores point for the Blue Earth. The voice recorder provides good results. The email account is easy to set and retrieving the messages depending on the size and attachment, is done very quickly. Finding and opening web pages with elaborately designed pages hardly takes time. Uncompromising and accurate synchronization takes place, also with Outlook. However, neither USB cable is included or some software in the package. The S-7550 has a rich selection of games (but unfortunately only to demo versions) and various other features, which enhance the Samsung as well.

    Memory expansion via Micro SD cards supports up to 16 GB (unfortunately under the battery compartment cover)

    2. Camera quality - In daylight and normal lighting conditions (indoors), the camera of the GT-S7550 made pleasing results. Colors are displayed on the screen in all their colorful splendor, and also when one looks at the images later on your PC, like the perfect color rendition. The sharpness is neat - but here goes even further. We recommend that you keep quiet and dont move when the cell phone camera shots, because otherwise the result is slightly blurry. In the darkness, it can capture only a little light on the subject. In total darkness it is not able to achieve any results. Unfortunately, it lacks a photo light or flash.

    3.

Zooming are not heard in the background of the clip (with some other competitors, this is often the case). In the darkness, you can achieve any results. In low light, and only a very weak color, contours are barely recognizable. It also lacks the video light.

    5. Equipment to the built in music player - Playable formats: MP3, WMA, AAC, AAC +, Music Library: All tracks, playlists, Recently Added, Artists, Albums, Genres, current playlist: send by: Message, Email, ActiveSync, Bluetooth options: Set as: callsign for voice call, call sign for video call, caller ring tone, alarm, details: name, format, size, distribution, date created: on / around, place, artist, title, album, length of the title, genre, copyright, description, number of the title, format ; settings: background music: on / off, normal sound effects:, rock, pop, dance, classical, jazz, wide, dynamic, surround; Music menu: Playlists, recently played, most often played, Recently Added, Artists, Albums , genres, composers, Repeat All, one; Play: coincidence loop.

    6. Sound quality of the music player - The speaker is positioned at the back below the solar panels. In the medium and low frequencies songs sounds alive and fresh. The treble has a pleasant sound characteristics. Even at higher tones or songs with more bass activity, the playback is not too distorted. With the built-in equalizer, one can improve our songs and vote freely. The included headset implements a balanced sound with good space.

    7. Radio yes / no, sound quality of radio - Add FM Radio with RDS; to favorites to open Favorites, open Record: search,: pause, stop, settings: Background Music: on / off display, Sender ID: on / off; alternative frequency: on / off, radio text: a / out; Standard name: radio, standard memory: phone, memory card, FM radio; Favorites: Adding, editing, set an alarm, program information, attitudes, that in good alignment of the antenna (headset) is the reproduction of the respective channels do not criticize. The recordings from the radio are very useful and sound good.

    8. Storage Capacity / position of the memory card - 180 MB of dynamic memory using SD memory cards up to 16GB.

    9. Multimedia Results - The camera equipment of the Blue Earth is easy to use and has useful settings. The results of the 3.2 MP camera can be quite respectable. The results of the video footage only score points if you avoid quick movements. If a photo light / flash was available, one would certainly be able to move ahead in the dark to get good results. The built-in MP3 player can be used very easily. Play lists are fairly simple and easily applied. An FM radio with RDS is built in the GT-S 7550 also. Equipped with sufficient transmitter sites, ease of use, fairly noise-free, clear sound and fine quality of the recordings, can also positively attract attention. The mobile phone has only 180 MB of internal memory but is expandable to 16 GB. Unfortunately, the insertion of the Micro SD card is situated under the battery compartment cover.

    11.

In addition, the GT-S7550 reads memory cards quickly and smoothly, and the data type of format also reflect perfectly. Unfortunately, the memory card slot is under the battery compartment cover. Moving your data is easily done and rapidly too.

    Accept - Back and end keys

    Overall Conclusion

    By showing Housing from recycled plastic that is free from harmful additives, and a built-in solar panel on the back of the Blue Earth, a mobile phone that can occur environmentally friendly and timely, remains as the initiative of the Koreans that comes just at the right time. But even under the classical aspects of the GT-S7550, the equipment does not present itself spartan and outdated, but plentiful and reasonably modern. The 3.2 MP camera with simple operation delivers good results under normal lighting conditions. The internal music player scores with ease of use and good sound even though the speakers are rear-positioned. The representation of the radio is in good alignment with the antenna (headset almost) and completely free from noise. The recordings of the radio surprise with fine results. Web pages load quickly, thanks to HSDPA that is well presented. Emails can be easily downloaded and are great to read. Even attachments are easily downloaded and well presented if they are not too large. The response of the touch screen is evenly and quickly done. With class-processing and chic design, the phone fits comfortably in your hand. The list of cons is short. The note function allows only 100 characters per note, the memory card slot is under the battery compartment cover, and in the dark, neither camera nor video cameras can deliver useful results because it lacks a photo-video light or flash. The overall impression is very positive, in spite of these three negative points. Market prices from just under EUR 230 for around this successful product is to be considered very fair.

    Re: Samsung Blue Earth GT-S7550 Mobile Phone

    I have one, it's alright but the interface can be infuriating at times. e.g. the backspace is right next to "Done" on the qwerty screen, which in turn is right on top of "Send" on the create sms screen behind it. That, coupled with the non-repeating nature of the backspace key (holding it wipes your entire text) means more than a few half-written texts containing something you'd changed your mid about saying ends up getting sent.

    Also the accelerometer is crap, but I've yet to use one that isn't.

    There's also a few weird eccenticities, like the qwerty keypad not having an ampersand (you have to revert to numpad for that).

    The lack of a d-pad means positioning the cursor in text is difficult.

    The browser won't render my local bus tracker web site, but the WAP version of the same site causes the phone to crash every time. Joy.

    There's no option to lock the widget layout, or line them up, so they all end up half-dragged around the place. Annoying if you're borderline OCD about stuff like that. Also depending on your provider there's often no way to delete unwanted crap (like Yahoo! on O2) from the widgets bar.

    All negative points, but just niggles really. On balance I like the phone - just. It's good if like me you rarely use your phone and want something with monumental battery life on a cheapskate contract. Speaking of which, the battery life is the #1 standout feature for me. I make on average 2 five minute calls a day and send half a dozen texts, don't use the MP3 player or anything, and I get 8 days out of it easy. On that front it's like having a Nokia 3210 again.
