Hello, I'm new to this forum and also new to Android. At the moment I'm trying to tweak an Android device. The problem is that the x-axis is inverted, but the y-axis isn't. So when I want to select something top left, I need to press top right. The touchscreen is working correctly when connecting on my windows desktop. Maybe there is a problem in the Android source code or just a reinstall of Android on the hardware device. But how can I reinstall android(for example android 2.2)? I'm using Ubuntu 11.10, Android SDK, Eclipse + ADT Plugin. I can install apps on the device with adb. PS: English is not my native language, so there will be some grammar errors probably.
