The Nokia 6233 phone made by Nokia is the successor to the Nokia 6230i. It is a 3G (Though it does not have a camera for video calling) GSM/WCDMA mobile phone that runs the Nokia Series 40 (S40) 3rd Edition UI operating system. The phone is said to be the the loudest mobile around as it has two speakers. In comparison to predecessors it has some serious restrictions concerning the user interface, e.g. one can not adjust the brightness or duration of the display backlight. There is also a "Music Edition" sold in Asia regions that comes bundled with the Nokia Music Stand, 512MB microSD card and A2DP Bluetooth profile support. As of april 11th 2007, the newest firmware is version 5.1, which was published December 21st, 2006, and includes A2DP stereo headset support.
The standard phone supports a variety of music formats including AAC (Used by iPods), Mp3 and WMA files. The Actual MP3 player supplied on the phone only shows the list of songs, and on larger memory cards (e.g. 2GB) it can be easier to play the music direct from the file, but this does not support multi tasking, leaves the backlight on and does not allow the keypad to be locked.

Good battery life
FM radio with 20 channels
High quality 3D graphics for games
Bluetooth 2.0 EDR technology, supporting multi-connections
Small-sized 3G phone compared to other 3G Symbian-based phones
Fast and responsive menu due to the less demanding Series 40 software
Disadvantages
Brightness and duration of the display backlight are not adjustable
Phonebook contacts memory is limited to 500 entries only
Camera has neither flash nor macro mode
Low internal memory of 6MB
Phone supports only USB 1.1 data cable speeds
It is a 3G-compliant phone but it lacks a front camera despite supporting video calling (users have to purchase an additional external camera, flip the phone backwards, or sit facing a mirror, in order to perform a video call).
It is considered a "Music Phone" but does not have any special music function keys like the Nokia 3250 or Nokia 5300
Does not include USB data cable in package. (some countries offer though i.e. Philippines)
Video playback lacks rewind/fast-forward functionality (this problem can be resolved with 3rd party video playback softwares)
Known Issues
Neither brightness nor duration of the display backlight are adjustable - after 10 seconds the display goes dark until you press a key again
The phone has been known to restart by itself automatically while performing a task, for example when viewing a video in fullscreen or playing music.
Users are complaining that the maximum contact entries of 500 is not sufficient. Earlier Nokia models support up to 1000 contacts and it is unknown why the Nokia 6233 has this limitation.
Images taken with the built-in digital camera sometimes contains dead pixels. Red pixels can be seen on the same spot for all photos taken.
When contacts Name display is set to Last name first the order is corrupted after the phone is powered up. Contacts are not sorted and go missing as you scroll through the contacts list. Only by reselecting the setting Last name first after each time the phone is powered up will the order and contacts be restored.
Phone will sometimes lose signal, the only way to reconnect to the network is to power cycle.
No Camera Shutter cover, so dust particles will affect camera quality..
It is prone to screen burn.
The Phone memory becomes full even without adding anything.
