We’ve received more than a few tips that users are experiencing signal issues with the Samsung Galaxy Nexus. I can’t personally verify the claims — I have yet to take my Nexus outside of a 4G zone — but based on a recent tweet from Verizon’s support account it does appear that something isn’t quite right. Users are reporting familiar sounding 4G issues, such as poor handling of the switch between 3G and 4G mode (toggling airplane mode tends to fix this) and lower-than-expected reception strength. Verizon says it is investigating the problem and developing a software update to address the problems, but a release timeframe is unknown. Our best guess is to expect any signal-enhancing tweaks to come bundled as part of the Android 4.0.3 update planned to arrive on Nexus handsets in the coming weeks.
