Solving Startup Installation Problem for Nokia Smartphones

solving automatic install on startup e63 nokia :
As for the installation problem, I think its due to .sis files stored on the phone memory or in sensitive folders in the memory card or its as a result of incomplete installations. When the phone is restarted, it tends to automatically install does files for you. I've had this problem on my N95.

What I suggest you do is, go to the Application manager, scroll through all the files listed, look for apps with a "not installed" status and then you either install these apps manually or delete them. I hope this helps...

OR

To resolve the automatic installation at startup problem:

1. connect the phone to the PC
2. Make sure you are showing hidden files in Windows
3. Browse the memory card and find the private10202dce folder, and delete all contents

Android will Dominate be 2014 !

Gartner Says Android to Become No. 2 Worldwide Mobile Operating System in 2010 and Challenge Symbian for No. 1 Position by 2014
STAMFORD, Conn., September 10, 2010 —    The worldwide mobile operating system (OS) market will be dominated by Symbian and Android, as the two OSs will account for 59.8 percent of mobile OS sales by 2014, according to Gartner, Inc.

Symbian will remain at the top of Gartner's worldwide OS ranking due to Nokia's volume and the push into more mass market price points. However, by the end of the forecast period, the No. 1 spot will be contested with Android, which will be at a very similar share level.

Communication service providers' (CSPs') marketing and vendor support for Android-based smartphones will drive the platform to become the second-largest platform, following Symbian, by year-end 2010 (see Table 1). This is almost two years earlier than Gartner predicted a year ago.

"The worldwide mobile OS market is dominated by four players: Symbian, Android, Research In Motion and iOS," said Roberta Cozza, principal research analyst at Gartner. "Launches of updated operating systems — such as Apple iOS 4, BlackBerry OS 6, Symbian 3 and Symbian 4, and Windows Phone 7 — will help maintain strong growth in smartphones in 2H10 and 2011 and spur innovation. However, we believe that market share in the OS space will consolidate around a few key OS providers that have the most support from CSPs and developers and strong brand awareness with consumer and enterprise customers."

Forecast: Mobile Communications Device Open OS Sales to End Users by OS (Thousands of Units)

Gartner expects manufacturers such as Samsung to launch many new budget Android devices in 2H10 that will drive Android into mass market segments. Other players, such as Sony Ericsson, LG and Motorola, will follow a similar strategy. This trend should help Android become the top OS in North America by the end of 2010.

"CSPs and mobile device manufacturers alike will need to revisit their platform strategies and balance the need to pursue platforms with the highest current demand against the need to maintain differentiation with unique devices," Ms. Cozza said. "CSPs will likely reduce the number of platforms they offer, to reduce their support costs and clarify their propositions to market."

Gartner predicts that by 2014, open-source platforms will continue to dominate more than 60 percent of the market for smartphones. Single-source platforms, such as Apple's iOS and Research In Motion's OS, will increase in unit terms, but their growth rate will be below market average and not enough to sustain share increase. Windows Phone will be relegated to sixth place behind MeeGo in Gartner's worldwide OS ranking by 2014.

Resistive Vs Capacitive pros and cones

Capacitive touch screen:

Pros:
Multi touch support available
Visibility good even in sunlight
Highly sensitive to finger touch leading to ease of use
Not prone to dust particles
Glossy look and feel
Cons:
Need to have atleast 5% humidity to achieve capacitive effect
More expensive than Resistive touch screen
Doesn't work with inanimate objects/fingernails/gloved fingers
Latest technology, may need to evolve a bit more!

Resistive touch screen:

Pros:

Relatively cheaper
Can operate with any pointing devices like stylus, pen, nail etc
Can operate at any level of humidity
Ease of use, as it could be used even with your winter gloves on!
Very useful for people using handwriting recongition system, due to ease of use with a stylus!
More accurate than capacitive touch screen!
Old technology and hence more reliable!
Cons:
Multi touch support not available. Though technology did evolve after some modifications with the existing resistive touch screen circuitry, its still not 100% developed yet!
Highly sensitive. As it can operate with almost any sort of pointing devices, can be more vulnerable with dust particles!
Poor visibility in sunlight, mostly due to multiple layers reflecting light!
Screen, being sensitive at the upper layer, can be more vulnerable to scratches!

So, now that you know the difference between Capacitive touch screen and a resistive touch screen, along with some of its associated pros and cons of each of them, you should now be in a better position to judge which touch screen might be suitable for you!

Resistive Touch Screen Vs Capacitive Touch Screen

Resistive
A resistive touchscreen panel is composed of several layers, the most important of which are two thin, metallic, electrically conductive layers separated by a narrow gap. When an object, such as a finger, presses down on a point on the panel’s outer surface the two metallic layers become connected at that point. This causes a change in the electrical current which is registered as a touch event and sent to the controller for processing.
Capacitive
A capacitive touchscreen panel consists of an insulator such as glass and coated with a transparent conductor. As the human body is also a conductor, touching the surface of the screen results in a distortion of the body’s electrostatic field, measurable as a change in capacitance.
