About SignalCheck Pro
SignalCheck allows users to check the true signal strength of their connections. Unlike the standard Android signal bars, which typically only display the 1xRTT (voice and low-speed data) signal strength, SignalCheck will show you detailed signal information about all of your device's connections, including 1X, GSM, EV-DO or eHRPD (3G), LTE (4G), and Wi-Fi.
Special thanks to S4GRU for their tremendous support of SignalCheck from the beginning! Visit http://www.S4GRU.com for up-to-the-minute information and discussions about Sprint's Network Vision strategy, as well as talk about devices and other cellular networks. There is a SignalCheck discussion thread too!
SignalCheck will display LTE Cell ID information on most devices running Android 4.2 or higher, and some HTC devices on earlier Android versions. SignalCheck was one of the first (if not THE first) Android apps to provide this information to users. LTE band information is available for some providers, and frequencies are displayed on some HTC devices.
A configurable SignalCheck widget can be added to your home screen, showing your realtime connection type and signal strengths.
SignalCheck also displays the current connection type along with the carrier name for each connection, even while roaming. Sprint users are instantly able to see if they are on the new 800 or 2500 MHz (Spark) networks, part of Network Vision!
One of the best features of SignalCheck are the notification icon(s). A user-customizable icon shows your data connection strength in the notification area at the top of the screen, and more details can be seen in the pulldown menu. Your signal strength is always at the top of the screen along with your other icons.. no need to open the app to check your connections. The icons are customizable, showing signal bars, connection type, digital signal strength in dBm, or connection type with signal strength. A secondary icon can be enabled to always display the 1xRTT signal for users who wish to compare their signal strengths realtime. All of this is customizable from within the app! Users can configure this to automatically start when their device boots up if they choose to.
SignalCheck can also notify the user with optional audio and/or vibrating alerts when a 4G LTE connection is discovered. This is handy for users traveling in new cities, or if your carrier's network is being upgraded -- know immediately when you have a high-speed connection! Sprint users can also enable alerts to notify them when they connect to 800 SMR.
Curious as to which tower you are connected to? SignalCheck will not only show you the ID, but also the street address of the 1X tower or sector on most CDMA networks! Clicking on the address will automatically show the location through your mapping app. Users can also add custom "Site Notes" for each site they connect to.
SignalCheck has an option to quickly reset your data connections from within the app (root required on Android 4.2+). Another option allows users to start checking their signals as soon as their device boots, enabling the notification icon(s) immediately.
SignalCheck provides easy access to advanced Android screens such as Data, Debug, Engineering, EPST, and Field Trial, along with Battery Info, Field Trial, Mobile Networks, and Wi-Fi info. These screens are already available on most Android devices, but are only accessible by special dialer codes.
SignalCheck is a great compliment to the Sensorly app, allowing you to check your signal strengths and map them out so other users can see the data as well.
This app has also been referred to as Signal Check, Signal Check LTE, LTE Signal Check, and LTE Checker, among other things. Users checking their signals on the Sprint network will see the most benefit from this app as their Network Vision nationwide upgrade rolls out, but Boost, Verizon, AT&T, T-Mobile, and international users can also check their signals and see detailed information about their connections.

I use this app everyday through work doing RF signal testing and it is far and away the best app for diagnosing your current connection. Also on Sprint it shows Carrier Aggregation info which is nice. A few complaints I noticed in other reviews were the lack of 1x info, I'd like to point out that if the device is an eCSFB or CSFB device using one radio it will only show the current connection so if you're connected to LTE you will only get LTE info, it's the way the phone is made not the app's issue.

Great app for the most part. Only problem I notice is that the status bar icons don't seem to color-invert like other icons do when the status bar turns a light color. So, if the status bar is light then other icons turn grey-ish but SignalCheck icons stay white so you can't see them.

Awesome app when it works on my Nexus phones and pixel XL. But it never works on my honor 8. I definitely have LTE and I can use the internet just fine, but the app keeps telling me that there is no LTE connection.

Doesn't work on dual sim phones, doesn't show new AT&T band 30, doesn't show carrier aggregation. Fine otherwise, just needs updated. UPDATE: still no support for above.....

Best I've found for getting detailed information about my mobile data connection for Project Fi on multiple carrier networks. First I saw to accurately report T-mo band-12 usage, and Bell/Rogers in Canada.

The app is pretty straightforward and I am looking forward to keeping my carrier honest. I am learning. A quick question: address information does not display on cell sites. Only something like "0.1 m N." Any ideas on how to turn this feature on? I have everything enabled. Using HTC 10 on Sprint. Android 6.0.1.

Running on the Samsung Galaxy S4, Doesn't show the Signal strength in dbm, and no information on main screen of app. Only W-CDMA... showing N/A in the notification bar...... I hope I didn't waste my money

Being a technical support for Wilson Electronics, we rely heavily on signal strength since the bars are a pathetic joke. I used Advanced Signal Status in the past that would break down 3G signal info and 4G signal info but it would give you a ton of data that wasn't useful and served to confuse customers I was working with. This app give you the same info in a simple interface that is easily read that is still accurate. I can't recommend this app enough. Edit: We have tested its accuracy for Verizon and Sprint but not AT&T or T-Mobile as of yet.

This works well on one phone, barely works on another! The Good: I decided to try this out since I am experimenting with Project Fi and wanted to see which network/signal I was connected to at home/work/etc. On a Nexus 5x and with Project Fi, it works great: lets me know which network, which band, and signal strength. Helpful for figuring out which network I am benefiting from on Fi. the Bad: I have an Xperia Z3 Compact (D5803) on AT&T which *does* get LTE signals, as evidenced by the system and the download speeds I get. This app does not seem to work with the Sony. It says "connected to LTE" and "LTE no connection" at the same time and in the notification bar shows "--" for which band and signal strength. I have tried several other similar apps and they *do* show the correct info such as "band 17 -98 dBm" so I am not sure what the deal is. Since it works for the device I really needed it for, I give it 4 stars, but not being compatible with a totally stock device costs it 1 star.

This app unfortunately does not seem to work with Huawei devices and their Kirin processors. It will only show your WiFi connection and no cellular information. So try out the free version before you waste your money on the pro version!
