If you have a slow Sony Xperia Arc, then probably you have Timescape and carrier bloatware that makes your phone slow (e.g. Rogers in Canada). In this tutorial, I will explain the steps that I did to make the phone considerably faster.

Install PC Companion and Update Service

In order to flash a new ROM on your phone, you will need first to install Sony Ericsson's PC Companion as well as Update Service on your Windows computer. This is needed so that the required USB drivers are installed and configured.

Install Flashtool

Do you have a Sony Ericsson Xperia phone running Android? Such as the Xperia X10 or Xperia Arc? Is it slow and lags often?

We have a solution for you ...

But before we tell you, we have to explain why Sony Ericsson's Android can be slow. The reason is Timescape, Sony's user interface for Android phones. Even if you disable all the Timescape widgets from your home screens, it will still be running under the hood.

You can root a Sony Ericsson Xperia Arc from Rogers (Canadian mobile phone network), using the zergRush method.

The method works for Xperia Play and other models as well.

For this, I used an Arc running Android 2.3.3 Gingerbread.

Using Windows

Follow the instructions on the above page.

Using Ubuntu

1. Download the package.

wget http://ubuntuone.com/7mD63kpsKzGmaou5hcftBV

2. Rename the package.

mv 7mD63kpsKzGmaou5hcftBV zergrush.zip

A very nice surprise from Sony Ericsson. Even though Android does not have full and official support for Arabic until Android 4.0, their handsets do have very good Arabic support by default, even handsets sold in the USA and Canada.

Arabic in Sony Ericsson Xperia Android phone

If you have Android 2.1 or 2.3 and updated it to the latest update from your carrier, then you do have Arabic support. To check if it works, then just visit BBC Arabic and see if Arabic shows correctly and the letters are connected.

Enabling Arabic keyboard

To enable Arabic typing, you need to press Menu, then select "Language and Keyboard", then under "Keyboard settings" select "Default input", then select "Writing Languages", and check "Arabic". You will then see a language switching icon on your keyboard (the "globe" symbol).

Not only does Arabic work well, the font looks much better than what is in CyanogenMod for example.

This is a a list of Android applications that I currently have on my phone. Some are more often used than others, but all are useful.

These apps are running on my Sony Ericsson Xperia Arc, which has Android 2.3.3 on it. Most of them ran on the Sony Ericcson Xperia X10 as well.

ADW Launcher is a fast and feature rich home application replacement. Use it instead of Sony Ericsson's TimeScape and your phone will feel faster.

This is great news!

Sony Ericsson decides to cooperate with independent custom Android ROM developers.

They started with publishing steps on how to unlock the boot loader, and how to build the Linux kernel for Xperia phones.

Thanks Sony Ericsson ...

Update 2011-09-02

For the Xperia X10, when upgrading the software using Sony's PC Companion, you will get full Arabic support on the phone, with a beautiful font, and no glitches. The only drawback is the phone is unrooted, and therefore you lose functionality of apps that require root (e.g. Titanium Backup, ShootMe), and have the bloated apps that autostart (Timescape, Moxier Mail, ...etc.)

Experimenting with the CyanogenMOD custom ROM on an HTC T-Mobile G1 Android phone, I frequently encounter that the camera would get a "force close" error. After the application exists, the camera app would not start again, unless you reboot.

Since this takes some time to do, and is inconvenient, I found another way to reset the camera without rebooting.

Here are the steps.

1. If you do not have the ASTRO file manager, install it. The link has the QRCode for it.

So, over the past few days, I had an interesting issue with Android 2.1 (Eclair) on a Motorola Milestone.

Suddenly, it decided to stop syncing emails with Gmail. At the same time, syncing the calendar worked fine.

I tried solving this using by selecting another label, and then went back to the Inbox and it seemed to work, but in fact, it did not. It would show the correct number of unread messages, but the actual unread messages will be from an old sync. Very confusing.

Here is the solution:

Press Menu -> Settings -> Applications -> Manage Applications.

When you reach there, press Menu -> Filter -> All.

Scroll down to find "Gmail Storage", then click "Clear Data".

Confirm that scary looking dialog.

Things will be back to normal.
