Fixes for Nexus One 3G issues & Touchscreen

An update on some temporary fixes for the first version of the Nexus One.

How to force a 3G Connection

Step 1

Go to phone dialer. Dial *#*#4636#*#* You might not actually see the final asterisk appear, because as soon as you hit it, your phone’s going into testing mode.

Don’t worry, this isn’t anything as serious as rooting, and you’re not going to brick your phone. Promise.

Step 2


OK, now you’re in testing mode, and you should see four options. Tap on “Phone information”

Step 3


Scroll all the way to the bottom of the “Phone information” screen.  Under “Set preferred network type,” Tap where it says “GSM only.”

Now, change it to “WCDMA only” . This will set the phone radio to only connect over 3G. Remember: If you’re not in a T-Mobile 3G area (which is always the case if, like me, you’re using AT&T), you will not be able to get a data connection at all.

By the same token, you can force it to EDGE-only by choosing “GSM only.” And, yes, there are some CDMA options.

Touchscreen Problem

When touchscreen calibration occurs on the phone, a temporary fix would be to do a soft reset (press power, volume down and the trackball simultaneously).

Google is working to fix these issues, but if it can’t be solved through a software update, the Nexus One Warranty covers this.
