I’ve been using the Nexus One on t-mobile for a few days now, and while a LOVE this phone overall, I have not been impressed with its 3G performance.
Metro-Boston and surrounding suburbs supposedly have very good 3G coverage, at least according to t-mobile’s map, so I was hopeful being spoiled by Verizon’s excellent network performance and coverage. I noticed right away that the phone kept switching networks and didn’t seem to hold onto the 3G signal very well, regardless of my location.
A quick check of the Google support forum revealed that a number of people are experiencing the same problem.
It’s hard to tell what is causing this, and if this is a hardware or a software problem. I did notice one thing though. My phone is connected to 3G in my house and I can use data services at 3G speeds as long as I keep it on my desk. As soon as I pick-up the phone and hold it in my hand, 3G disconnects and the phone falls back to Edge.
Here’s a short video:
Update: Apparently there is a configuration screen that allows you to select network preferences. Some people suggest that forcing 3G (pick WCDMA only) will remedy the problem. You can get to the configuration screen by simply dialing the following number *#*#4636#*#*. Proceed at your own risk. I tried different settings and did not notice any improvement.
Update2 – From the T-Mobile Forum: Google and T-Mobile are investigating this issue and hope to have more information for you soon. We understand your concerns and appreciate your patience.
