[XPERIA X1 Android Development] jamesalfred:
Hi all, I'm gonna try to share what I've been doing and experienced with this build of Android on Xperia. I hope this will be helpful :D

First of all, before running Android, try to reduce the memory consumption of your WinMo first, i.e. removing programs, turning off clear type text, turning off receive all incoming beams, turn of the Today screen, etc. I've come to this consideration because Android still runs on WinMo OS, so making the WinMo as light as possible would probably help :D.

After that, you can follow the tutorial on the first page, and update to the latest kernel. I'm using angusmcb's kernel posted on page 6. After that, get into the Android itself. This is the list of useful tricks that I believe will improve your Android experience by getting it faster and comfortable:

1. Turn of vibration and haptic feedback. Yes, turn it off. Xperia's vibration system wasn't made for haptic feedback, even worse, I think the Xperia itself wasn't made to vibrate :(. Some of you might notice that when it vibrates, it feels like the slider and the screen will fell of the place. Imagine that happens each time you punch that OSD keyboard.... Turn it off.

To turn it off, go to Settings -> Sound & Display -> Uncheck the Phone Vibrate. Also uncheck Haptic Feedback. This will turn off the phone overall vibration, including the nasty vibration when you try to shutdown the phone. But take note: this doesn't turn of the haptic feedback while typing. To do that, go to Settings -> Language & Keyboard -> Touch Input-> Text Input -> Unheck Vibrate While Typing

Believe it or not, I felt the text input become slightly faster after turning off haptic feedback :D

2. Set the phone to Silent Mode. As you might know, this build of Android still doesn't support Sound output (though vdelf is working at it as we speak now :P), so why don't we just turn it off? Go to Settings -> Sound & Display Settings -> Check Silent Mode. Hopefully this will give us a little bit more resources....

3. Download Advanced Task Killer Free from Market Place. This tool is astonishingly useful to relieve memory usage. Just download it from Market Place and run it. After you run it, you can check what programs / services are running on the background. Kill everything. Yes, everything except the Advance Task Killer itself. After that, you'll notice that your Android become blazing fast. Remember to do this regularly, especially after browsing and accessing Market Place...

Something you MUST take note for:

1. DON'T touch anything related to Brightness inside Android, including the one on the Power Control Widget. As I've mentioned on my previous post, it seems that it caused you screen to flicker the entire time. No use restarting it, as it will flicker on the WinMo as well. I need more confirmation on these. I managed to solve the flickering by formatting my device.....

2. Turn off WiFi when not needed. Turning it off and using it for an extended time will cause your Xperia feels really hot. I mean REALLY hot. Almost comparable when using Palm Pre.... This also cuts your battery life significantly.

3. To change your wallpaper, you can't go to Gallery -> All Pictures -> then selecting your wallpaper. It won't work. It'll say that the Camera application has stopped working and you must force close it. To change wallpaper, go to Home screen, then go to Menu (by clicking the upper left button) -> Wallpaper -> change the wallpaper from there. Sometimes, your phone will freeze and restart by itself. Don't worry though, the wallpaper will be there.

As for the latest kernel by angusmcb's :

1. The shutdown works perfectly. The device will go off instead of rebooting itself like in the previous kernel.

2. I don't know about battery consumption, as I can't measure it. But it seems to be improving.

3. I don't know, but I feel like it's getting a bit slower than before. Juuuust a tiny bit. Doesn't matter though :D

Nice release by the way

That's it. Hopefully this will help you all. I'll post later if I found something interesting. Cheers.
