Samsung devices running Android 5.0 (lollipop) or later require arooted device with SuperSU 2.49 beta or newer in order to use theadditional settings shortcut. I won't be responding anymore toreviews/emails telling me the "additional settings shortcut"doesn't work for devices without root and rooted devices that don'thave at least SuperSU version 2.49 beta. If you need that shortcutto work, please follow directions and root your device beforeblaming me or telling me it doesn't work. The shortcut does workfor most other rooted Android 5.0 devices and tested on my stockMoto (2014) X and Nexus 5. Android 4.x devices (not Samsung) workwithout root 99% of the time --- What do this app do? --- ► Togglebetween 3G and 4G with a few clicks for nearly any deviceregardless of manufacturer. ► View all statistics your carrier usesto determine signal quality and 3G to 4G hand offs for CDMA, LTEand HSPA/HSPA+ in real time. ► Easy to read 3G and 4G statistics inpercentages based on the max/min values instead of just decibels. ►Quick access to info you can reference when you need to complain toyour carrier about poor reception in your area. ► Find dead spotsaround your home/office that affect phone calls, but not data (ordata, but not phone calls). ► Reception quality can be misleadingwith bars only. See all the data Android and your carrier hidesfrom you to determine signal quality and how it varies. ► Access tolow level information about your previous and current wificonnections, including the current signal in decibels. Annoyed atthe lack of network signal information for your Android phone yourcarrier hides from you? Can't switch between 3G and LTE easily withyour phone? Wish you could know more about the statistics yourcarrier uses to determine many bars your phone has and the tower itconnects to? Want to see what your 3g and 4g signals are at thesame time and also switch between them easily? Try out this freeapp and see all that information you've been missing when you couldonly look at number of bars and one signal under status settings.Also includes hidden configuration settings (cell radioconfiguration, wifi config, battery info) normally invisible tousers. Compare your signal quality based on percentages instead ofjust decibels. Now, you can instantly see how great each signalreading is for your device based on a scale of 0% (worst) to 100%(best). Percentages are configured to give the best reading foryour carrier by default. Use the info contained in this app tomonitor your current signal and find dead spots around your homeand office. Also useful for complaining to tier 2 tech support withyour carrier when your signal sucks.
