Mobile operating systems: Series 40

Features

Let’s begin with telephony functions. The phonebook’s capacity varies from model to model, it’s usually between 1000 and 4000 names. There’s no problem with that, but this capacity is only displayed as a percentage, which is quite disturbing as it is inaccurate at such a size. There are different views for the contact list: we can display phone numbers under the names, and font size can be changed, as I have previously mentioned. Another useful feature is that we can see contacts on the SIM card and in the phone’s memory at the same time. There are 15 extra fields, which is quite satisfactory. We can create groups and assign unique ringtones to them. We can synchronize the contact list, but I won’t go into details regarding this one. There is a list of profiles to choose from and of course all of these can be customized; the devices can ring and vibrate at the same time.


Contact list

There can be no complaints about messaging. There is delivery reporting, we can save sent messages, etc. Usually no e-mail client is included in cheaper models, but it’s present in the mid-category and above: it supports authenticated IMAP servers and attached files too. Text entry is assisted by a multilingual T9 dictionary.


Messaging

Statistics are a strong side of the system. In the call log there are separate views for dialed/received/missed calls but we can also view them in one list, we can check details for every one of them (time and duration of call). There is a message and a data counter, both of these can be reset to zero with a few button presses.


Call log

The calendar is a very powerful tool, it has month, week and day view too. Entries can be of one of the five categories: meeting, call, birthday, memo, reminder. We can only store one time point in the alarm clock, but we can set it to repeat, we can set snooze duration and what’s most important: the alarm goes off even when the phone is turned off. Entries can have a maximum length of 3000 characters, and the sound recorder (which is for some reason in the multimedia section) can record for max. 1 hour. The countdown timer, stopwatch and calculator are all included, the latter has scientific functions in more advanced phones (sine, cosine, pi, squaring). Somehow the currency and measure converter is always amongst the MIDlets, but it’s great from the point of view of functionality.


Calendar

The built-in web browser is not bad, but recently Opera Mini is also included, which momentarily is the most popular application of its kind. The built-in browser handles HTML, XHTML and WML 2.0 standards, supports JavaScript, can break text, there is a fullscreen view and that’s about it.

There are great differences in games and additional software; practically all phones have different applications. The world clock and the friend finding Sensor are usually included on all handsets and we can also meet Yahoo! Go and the content manager called Catalgos.
