The Motorola Krzr K1 has two audio players. One is a simple app with a plain interface and the other is a bit more advanced, created in Java. The audio players play songs in MP3, AAC, and AAC+ formats. You can listen to the music through the phone's speaker, headphones or wireless headset. The phone also supports MPEG4 video capture and playback.
The phone comes preinstalled with some Java applications and you can easily download and run other applications that you want. The 2 MP camera supports a 1600x1200 pixel resolution and does not offer advanced video recording capabilities. Photos are poor quality and video is even worse. The screen can display 262K colors at 176 x 220 pixels which is far lower than the minimum 320 x 240 pixels, found on most phones nowadays.
The phonebook can hold up to 1,000 contacts, and each can hold additional numbers, an e-mail address, and the contact's birthday. The messaging features of the phone are SMS, MMS, E-mail, Instant Messaging and EMS. The built-in browser supports xHTML and WAP 2.0 but it's not an advanced browser, so you shouldn't expect many configuration options from it.
Other features of the Motorola Krzr K1 include voice dialing, speakerphone, voice recorder, vibrate mode, PC syncing, calendar, alarm, and e-mail. The connectivity options available on the phone are GPRS, EDGE, HSDPA and Bluetooth. The phone includes 12MB of memory, which is not large enough but fortunately a microSD card slot is provided so users can insert a memory card to store their large collection of music, videos, or pictures.
