I bought my Nexus S 4G back in July I think. It has been an amazing step into smartphones for me, but the only thing that I don't understand is why the home button and the back button blank out temporarily and I can't get out of it. Here's an example: I am in an app and I press the home key. It dims out and the recent apps screen comes up, blanking the rest of the screen. It sits this way for about 20 seconds and I cannot hit the back button to get out. Then it is back again to normal. The back button blanks out sometimes as well in a similar fashion. It's like the phone is frozen. Why is this? My updates have been done. I've power cycled, but this is a continuing issue.
Let me know what I can do. Should I take the phone back?
I did research some information on the issue with the backlight dimming and it seems like this issue is under investigation and hopefully can be resolved in a future maintenance fix.
I have the same problem with the soft button to the far left (back) dimming out for a period of time and the phone appears to be hung. My first Nexus did not do this The one I have now (I ran over my other one) is running 2.3.7 but also did this with 2.3.5. Bit annoying really.
