iPhone 4 Retina Display vs Samsung Galaxy S Super AMOLED

UPADTE: Check out may Super AMOLED comparison videos here and here
————————————————————————————————————————————————————
Here’s a quick comparison between the iPhone 4′s Retina Display and the Samsung Galaxy S’s super AMOLED. The first thing you will notice is the PenTile Matrix sub-pixels arrangement on the Super AMOLED which make the panel look really inferior to the IPS LCD on the iPhone 4. People will automatically jump to the conclusion that the higher pixel density on the iPhone 4 is the winner here, but this isn’t the case. The problem here is the PenTile Matrix which cause the image to look fuzzy not the lower PPI. A interesting test would be to snap a couple of pictures of the Droid X or regular Droid screen and compare them to the Retina Display of the iPhone 4. Both Motorola handsets have a similar ISP LCD panel as Apple’s device (but with lower PPI because of the size of their screens) so you probably won’t notice any major difference other than the smaller size of the pixels on the iPhone 4 (check out how the LCD panel of the HTC HD2 compares to the PenTile Matrix on the HTC Desire here). I personally think that Apple made a good decision when going for an IPS panel instead of a Super AMOLED now that it is known that Samsung’s latest and greatest tech still uses the PenTile Matrix. Sure you won’t notice any big differences from a normal viewing dsitance but the text does look fuzzier and can be a little bit annoying after a while (but that’s just my opinion after my experience with the HTC Desire).

Two more videos comparing the outdoors visibility and veiwing angles after the break:

A good reason why Windows Phone 7 applications run in sandboxes and have to be certified

It was reported yesterday that a research conducted by SMobile Systems found out that over 42000 Android applications on the Android Market allow a third-party access to sensitive or private information and some of them even able to send text message or cal any number without requiring interaction from the user. Microsoft’s Brandon Watson took the opportunity to explain why Microsoft will only allow third-party application installation and distribution via the MarketPlace (like Apple and the AppStore) and also point out that such rogue applications won’t be able to run on Windows Phone 7 anyway because every 3rd party app will run in its own sandbox and use isolated storage:

First batch of iPhone 4 suffering from screen issues and antenna problems

Everything isn’t going too well today for Apple. It seems like the first batch of retail iPhone 4 has quite a few problems. First is the yellow tint / yellow bar present on some of the Retina displays. As you can see in the pictures this thing looks really bad especially on a white background. There’s still some hope though if this anonymous poster at the Apple insider forum is to be believed:

Apple is using a bonding agent called Organofunctional Silane Z-6011 to bond the layers of glass. Apparently, Apple (or more likely Foxconn) is shipping these products so quickly that the evaporation process is not complete. However, after one or two days of use, especially with the screen on, will complete the evaporation process and the yellow “blotches” will disappear.

How do I know? I was involved in pitching Z-6011 to Apple.

So the only thing to do now is to wait and see if this is the yallow bar goes away once the Organofunctional Silane Z-6011 finally evaporates.

Log-in into Xbox Live on Windows Phone 7

Microsoft’s Andre Vrignaud wrapped up a walk through post detailing the Sign-in and Login process of the Xbox Live feature on Windows Phone 7. As you probably already know you will be required to have a Windows Live ID to use a WP7 device and have access to all the cloud based services like MyPhone, Facebook, Windows Live Photos etc..

The first time you power on a Windows Phone you’ll be asked if you have a Windows LIVE ID. To show your Xbox LIVE account on the phone you need to enter the WLID associated to your gamertag. If you don’t remember the WLID username and password you can tap the information link “I have an Xbox LIVE account.” for instructions to find your WLID on your console.

Once you’ve completed that setup, when you enter the Games hub it will retrieve your Xbox LIVE account, and you’ll see your Gamertag and other Xbox LIVE profile information as you continue to use the phone. If you want to use a different WLID on your phone (e.g. you want to use your Messenger ID instead), you will need to use your console to repoint your Xbox LIVE account to the phone WLID before you make purchases in the Marketplace or use Xbox LIVE in the Game hub. You can find information on how to associate your Xbox LIVE account with a different WLID here.

After signing in with your Windows LIVE ID, you’ll land on the start screen which has a Games Hub icon. Selecting the Games Hub icon brings you to the Games Hub itself. Note that at this point the avatar shown is either your real one (if you’ve associated your Xbox LIVE account with your WLID), or a generic one (because you aren’t currently an Xbox LIVE member).

The Xbox Live integration in Windows Phone 7 is going to be Microsoft’s big differentiator and will hopefully be packed with games this fall when the first devices hit he market.

Motorola Droid X hands-on video

 

Here’s an extensive hands-on video of the Motorola Droid X shot during the launch event. The build quality seems too be really good and the screen is definitely better than the one found on the HTC HD2 and HTC EVO 4G (the Droid X’s screen has a higher PPI thanks to the 854×480 resolution and an IPS panel resulting in better viewing angles and contrast). The new MotoBlur UI doesn’t look too fancy and gets the job done IMO. Check out the video after the break (btw, the clicking sound that you will hear throughout the video isn’t coming from the handset but from the Autofocus of the DSLR camera recording the video…).

Android 2.2 Source code released to partners

Google has released the source code of Android 2.2 today alongside the Motorola Droid X launch event:

To celebrate, we are open-sourcing the new 2.2 version of Android, which we call Froyo, to our partners who manufacture Android devices around the world. Customers will enjoy great new features and improved browser performance. And developers will benefit from new tools such as Android cloud-to-device messaging (which makes it easier for mobile applications to sync data).

User should expect to see Android 2.2 for their device later this summer.

iPhone 4 vs Motorola Droid X size comparison

The Engadget team has juts posted a quick size comparison between the iPhone 4 and the recently announced Motorola Droid X. With it’s massive 4.3″ screen the Motorola Droid X obviously dwarfs the sleek looking iPhone 4. Interestingly the Droid X is nearly as thin as the iPhone 4 but gets thicker at the top because of the camera and dual LED flash. It would be interesting to hear the what it feels like to use the Droid X on a daily basis given that I already find that the HTC HD2 is too big and hard to use with one hand (the Droid X is larger than both the HD2 and HTC EVO 4G!).
