[Android Apps and Games] mikejeep:
I created this app after realizing that trying to quickly see your 3G or 4G connection signal strength was not very easy. Most people get confused and think the signal bars on your screen cover whatever connection you have.. which is not always true.

SignalCheck Lite is a free Android app that allows users to see the true signal strength of their connections. Unlike the standard Android signal bars, which only display the 1xRTT signal strength, SignalCheck Lite shows you detailed signal information about all of your device's connections, including 1xRTT, GSM, EV-DO or eHRPD (3G), LTE (4G), and Wi-Fi.

SignalCheck Lite will display LTE Cell ID information on many HTC devices, as well as some devices by other manufacturers running Android 4.2 or higher. SignalCheck was one of the first (if not THE first) Android apps to provide this information to users.

YES SignalCheck Lite does show you LTE signal strength, and YES it works on all Samsung devices -- even if other similar apps don't! We have found our own solution to the Samsung issue.

SignalCheck Lite also displays the current connection type along with the carrier name, or the System ID of the carrier if roaming.

Sprint users will see a display indicating if their device is on the new 800 MHz SMR network. Future versions will also identify the upcoming 2500/2600 and 800 MHz LTE networks.

Grab it from Google Play: https://play.google.com/store/apps/details?id=com.blueline.signalchecklite

(There is also a Pro version which includes audio/vibrate alerts when an LTE or Sprint 800 SMR connection is discovered, data signal strength icon(s) in the notification area, auto-start at boot, keep the screen on, and other features. There is a small fee for that version, but the intent of this post is not a sales pitch.. just to say that I will provide support for SignalCheck Pro here if anyone needs it.)

New features are added often, and bugs are squashed as soon as possible. I'm open to any and all feedback, including criticism, suggestions, bug reports, and constructive criticism.. compliments are always welcome too. This is the first app I have created.. so please be gentle. ;)

When providing bug reports, please include your device, Android version, ROM, and if you are on a GSM network or not.. it helps tremendously.

Thanks,

-Mike
