Optimizing Shortcuts in S60 Phones

Tutorial 3 Comments »

How many shortcuts in S60 phones can you access with 1 key press only? How many of them can you access with 3 key presses or less? If you don’t know the answers, then keep reading…. :)

Firstly, go to the idle screen and look at the shortcuts on your left soft key and right soft key. They are accessible with one key press, aren’t they? So, these two shortcuts have to be assigned to the two applications you use most. Some people assign them to Messaging and Contacts applications. How about me? I have Messaging and Bluetooth applications (look at the picture below). Why Bluetooth? I need to switch on and switch off Bluetooth very often. I don’t want to switch on my Bluetooth the whole day to save my battery life. It’s a pity that most S60 phones don’t have Bluetooth hardware key.

One tip for your, do not assign Log application to either left soft key or right soft key. Why? Because you can access Log application by pressing Call key (the Green phone key). Best of all, you need only 1 key press to access Logs application.

Some newer S60 phones, such as Nokia 6680, N70, N71, N80, N90 and N91 have Active Idle feature. It is basically a list of applications on the idle screen. There are 5 to 6 shortcuts depending on the phone models. Look at the most left shortcut. How many key press you need to access this shortcut? Only one key press! So assign it with the next application that you use most. For me, I have Contacts application in most left shortcut.

For other applications, you need to press at least 2 key presses to access them. Look at the pictures above to see how many key presses you need to access a certain shortcut. The numbers above the circles indicate how many key presses you need. Note that you need only 2 key presses to access the most right shortcut. Press Left key and then press Scroll key. You don’t need to press Right key 5 times to go to the most right shortcut.

At the bottom of Active Idle menus, you can access Calendar and Todo applications too. That’s why I don’t assign shortcut to Calendar application in Active Idle, left soft key or right soft key.

What’s next? Press Application key (). You will see main menu as shown in the picture below. Look… you have one application selected once you press Application key. It means you have another shortcut that you can access with 2 key presses only! Press Application key and then press Scroll key.

Unfortunately, all other applications in the main menu need 3 key presses. You have to press Up, Left, Down and/or Right keys to access them.

Update (02-April-2006): You can also use ‘1′ .. ‘9′ keys to open a folder or application. For example, in the picture above, you can press ‘2′ to open Media folder or press ‘7′ to open Calculator application. Thanks to Zark.

What else? Some of the latest S60 phones, like N71 and N80, include a new hardware key, called Media key. It displays 4 additional shortcuts that be assigned to any applications (see picture below). Most of them can be accessed by 2 key presses. Press Media key and then press Up/Left/Right/Scroll key.

But wait a minute… why did I say “most”? The default application (the one in the middle) can be accessed with 1 key press only. If you press and hold Media key for about 1 second, your default application will be launched.

Now it’s your turn to configure your shortcuts. It is a simple thing, but many people simply don’t want to spend a couple of minutes configuring their shortcuts.

Reading News Without Internet Connection

Tutorial 7 Comments »

Some of you may have been syndicating and reading news feed on your mobile phones. There are some S60 applications out there that allow us to read news feed. Many of them use GPRS or 3G network to download the content. You can, of course, use WiFi too in some newer S60 phones.

Unfortunately, reading news via GPRS/3G is an expensive option for me. That’s why I almost never used RSS reader in my mobile phones. The situation has changed drastically since I downloaded MobiPocket Reader. MobiPocket Reader is originally an e-book reader application. However, they have extended the functionalities to support news feed reader too.

There are two things that I like about MobiPocket, i.e.:

  • It is free. Note that the application is free, but most of the e-books are not free. There are some free e-books, of course. One of my favorite is Trivopaedia, which is some kind like a small encyclopedia on your pocket.
  • You syndicate some free news feed, like BBC, Business Week, CNet, and many other news. This is the best thing; you can read news offline without any connection to the Internet. This is what I am going to explain in more detail.

Business Week BBC News CNet News.com

Here does how it works? There are basically two applications of MobiPocket Reader. The first one is installed on your phone, which is the one you actually use the read e-books or news. The second one if PC application installed on your PC. The PC application is the one that will syndicate your news. Once we subscribed the news, each time we connect our phones to the PC, the latest news will be copied (read: synchronized) to the phone automatically.

That’s the trick why we don’t need any Internet connection anymore when reading the news.

Here is what I have been every morning since a couple of days ago:

  • Startup my PC.
  • Run MobiPocket Reader.
  • Click Update button to get the latest news.
  • Connect my S60 phone to my PC.
  • The news will be synchronized automatically.
  • Disconnect my phone.
  • Take bus to go to work.
  • Read the latest news while on the bus.

Note: I don’t have any affiliations with Amazon or MobiPocket Reader. They don’t pay me either. I am just a happy customer.

Flash Memory Cards for Mobile Phones

Tutorial 3 Comments »

Many mobile phones nowadays support memory cards (a.k.a. flash memory cards) that allow you to store more files, such as images, music, videos or even documents. What I found interesting is the fact that there are several standards of memory cards out there. Different phone models are likely to support different memory cards.

From the customer point of view, it could be confusing. For example, MMC family, which is used by many Nokia phones, has several variants, i.e. MMC, RS-MMC and DV RS-MMC. I have tried to compile the list of flash memory cards that are used in mobile phones. Just a quick note, flash memory cards for other devices, like digital camera, are not included here.

MMC (MultiMedia Card). The standard of this flash memory card is defined by MultiMedia Card Association. It is used in many Nokia phones although some of newer Nokia phones support SD card too.

  • MMC / MMCplus - 24mm x 32mm x 1.4mm. MMCplus is newer standard with higher transfer rate.
  • RS-MMC (Reduced-Size MMC) - 24mm x 18mm x 1.4mm.
  • DV RS-MMC (Dual-Voltage RS-MMC) / - 24mm x 18mm x 1.4mm - It is the next standard of RS-MMC that supports dual voltages, i.e. 3V and 1.8V. The lower voltage is used to reduce battery consumption. RS DV-MMC can be used in the mobile phones that support RS-MMC, but not vice versa.
  • MMCmicro - The newest standard that is smaller than RS-MMC. It is not available in the market as the writing of this blog.

SD (Secure Digital). The standard of this flash memory card is defined by SD Card Association.

  • SD Card - 24mm x 32mm x 2.1mm. The dimension of SD card is similar to MMC, it is just thicker.
  • miniSD - 20 x 21.5 x 1.4mm.
  • microSD / TransFlash / TFlash - 11mm x 15mm x 1mm. This memory card is getting more and more popular. Some Motorola phones, including ROKR, uses microSD.

Memory Stick. This standard is mainly pushed by Sony and it is used in many of Sony Ericsson phones. Sony is a very big company, that’s why they can push their own standard of flash memory. The specification of Memory Stick is available at Memory Stick Developers’ Site.

  • Memory Stick Duo / Memory Stick Pro Duo - 20mm x 31mm x 1.6mm. It is the smaller version of Memory Stick / Memory Stick Pro, which are used in many Sony devices, such as digital camera. Memory Stick Duo can be used in Memory Stick reader using a special adapter.

Why don’t we have only one standard of memory card? Of course, there are some business reasons behind this. As a customer, I would see one standard only. It will make our life easier. We can exchange our memory card with our friends. We don’t need to buy a new memory card when we buy a new phone.

As a real example, at the moment I have three Nokia phones and each of them needs different memory card! I have Nokia 7710 that uses MMC, Nokia 6680 that uses DV RS-MMC and Nokia N80 that uses miniSD.

Update (5-Jan-06): Corrected SD should stand for Secure Digital. DV RS-MMC does not have to be MMCmobile (I removed MMC mobile from the list). Thanks to Petri for the correction.
