iPhone 4 Reception Problems are just Software Issues!

We have seen many iPhone 4 users posted their iPhone 4 Reception issues on YouTube. Finally there is official words from Apple. Apple have posted a letter regarding iPhone 4 reception issues due to touching the 2 antenna on the side of iPhone 4. Apple explanation on it is that it is software issue, the way that iPhone calculate the reception bar, it show more bars than the iPhone 4 is actually having. Thus when users touch the bars, the reception bars will drop very dramatic, but it actually only dropped 1-2bars of reception which most phone will drop when touch.

Here is the full letter from Apple:

Letter from Apple Regarding iPhone 4

Dear iPhone 4 Users,

The iPhone 4 has been the most successful product launch in Apple’s history. It has been judged by reviewers around the world to be the best smartphone ever, and users have told us that they love it. So we were surprised when we read reports of reception problems, and we immediately began investigating them. Here is what we have learned.

To start with, gripping almost any mobile phone in certain ways will reduce its reception by 1 or more bars. This is true of iPhone 4, iPhone 3GS, as well as many Droid, Nokia and RIM phones. But some users have reported that iPhone 4 can drop 4 or 5 bars when tightly held in a way which covers the black strip in the lower left corner of the metal band. This is a far bigger drop than normal, and as a result some have accused the iPhone 4 of having a faulty antenna design.

At the same time, we continue to read articles and receive hundreds of emails from users saying that iPhone 4 reception is better than the iPhone 3GS. They are delighted. This matches our own experience and testing. What can explain all of this?

We have discovered the cause of this dramatic drop in bars, and it is both simple and surprising.

Upon investigation, we were stunned to find that the formula we use to calculate how many bars of signal strength to display is totally wrong. Our formula, in many instances, mistakenly displays 2 more bars than it should for a given signal strength. For example, we sometimes display 4 bars when we should be displaying as few as 2 bars. Users observing a drop of several bars when they grip their iPhone in a certain way are most likely in an area with very weak signal strength, but they don’t know it because we are erroneously displaying 4 or 5 bars. Their big drop in bars is because their high bars were never real in the first place.

To fix this, we are adopting AT&T’s recently recommended formula for calculating how many bars to display for a given signal strength. The real signal strength remains the same, but the iPhone’s bars will report it far more accurately, providing users a much better indication of the reception they will get in a given area. We are also making bars 1, 2 and 3 a bit taller so they will be easier to see.

We will issue a free software update within a few weeks that incorporates the corrected formula. Since this mistake has been present since the original iPhone, this software update will also be available for the iPhone 3GS and iPhone 3G.

We have gone back to our labs and retested everything, and the results are the same— the iPhone 4’s wireless performance is the best we have ever shipped. For the vast majority of users who have not been troubled by this issue, this software update will only make your bars more accurate. For those who have had concerns, we apologize for any anxiety we may have caused.

As a reminder, if you are not fully satisfied, you can return your undamaged iPhone to any Apple Retail Store or the online Apple Store within 30 days of purchase for a full refund.

We hope you love the iPhone 4 as much as we do.

Thank you for your patience and support.


Pressure Sensitive Drawing on iPad!

Drawing on iPad is huge, lots of creative artists has been drawing and creating arts on iPad, because the screen size is just right, and it’s screen is very sensitive. Not only you can draw and see what you are drawing unlike tablet, where you are drawing on tablet pad rather than the screen. But one of the issue is that there are not pressure sensitive on iPad, so artists can’t apply tone as there are not pressure sensor on iPad. But not anymore!

Ten One Design who made Capacitive Stylus such as Pogo Sketch, Demo uses standard Pogo Sketch Stylus that pulls additional data from the iPad’s touch screen simulating pressure difference by measuring area of contact between stylus and iPad’s screen. In their App, they can even reject “touch” from screen, they reject things like your palm, so you can rest your palm on the iPad’s screen when you are drawing! Very useful, making drawing on iPad almost like drawing on paper!

iPhone 4 Manufacture Cost – $188

Components of iPhone 4 cost are broken down and calculated, they all together cost around $188, with Apple’s new Retina Display as the most expensive part in iPhone 4.

Here’s part of the break down:

Gyroscope Chip : $2.60, Gyroscope is use to sense iPhone movie in 3D

A4 Processor: $10.75, Designed by Apple, Made by Samsung, the same processor used in iPad

Retina Display: $ 28.50, Highest Resolution Mobile Phone Screen in the market!

Apple iPhone 4 is retailed at USD$199 with contract to AT&T, but the Manufacturing cost is around $188. It seems like a pretty good deal for consumers, we are almost paying for just the manufacturing cost, with AT&T or other carriers like Singtel (Singapore) covering the rest of the cost with our contracts.
