A few days ago I was trying to unlock the screen on my Dell Streak and I was having a hard time dragging the lock icon, it wouldn’t go all the way through and not responding well. I thought my Dell Streak was busy at first, maybe a process was using up a lot of resources in the background, but when I was finally able to drag it all the way and at the screen where to type in the password, I noticed that some sections of the touchscreen weren’t responding to my touch. I figured I probably need to recalibrate.
A quick Google search led me to this post: http://www.streaksmart.com/2010/10/how-to-calibrate-dell-streak-touchscreen.html
I’m just gonna repost it here so I can just search my website next time I need to do this :D:
- Power off your Dell Streak.
- While holding both Volume Up and Volume Down buttons, press the Power button. This will take you to the recovery mode screen.
- Press the Volume Down button a couple of times to highlight option 3, Screen calibration, then press the Camera button to select it.
- You will be prompted Are you sure you want to start calibration? Press the Volume Up button, then press the Volume Up button again on the next screen to start the calibration. The screen will shut off temporarily, don’t touch the screen.
- After a few seconds, you should see a message that it’s done, then press Volume Up again to start the calibration data check. Screen will shut off temporarily again, don’t touch the screen.
- After a few seconds, you should see another message message that it’s fully done and you’ll be brought back to the menu screen. You can then either power off your device and power it back on the normal way or just don’t do anything and wait for the device to reboot itself.
The screen calibration made a big difference, my Dell Streak now feels a lot more responsive :).
Note: I tried this on my Dell Streak running Android 2.2 Froyo, I’m assuming it’s the same for Android 1.6 since the calibration happens before the OS loads.
