Samsung devices running Android 5.0 (lollipop)or later require a rooted device with SuperSU 2.49 beta or newer inorder to use the additional settings shortcut.I won't be responding anymore to reviews/emails telling me the"additional settings shortcut" doesn't work for devices withoutroot and rooted devices that don't have at least SuperSU version2.49 beta. If you need that shortcut to work, please followdirections and root your device before blaming me or telling me itdoesn't work.The shortcut does work for most other rooted Android 5.0 devicesand tested on my stock Moto (2014) X and Nexus 5. Android 4.xdevices (not Samsung) work without root 99% of the time--- What do this app do? ---► Toggle between 3G and 4G with a few clicks for nearly any deviceregardless of manufacturer.► View all statistics your carrier uses to determine signal qualityand 3G to 4G hand offs for CDMA, LTE and HSPA/HSPA+ in realtime.► Easy to read 3G and 4G statistics in percentages based on themax/min values instead of just decibels.► Quick access to info you can reference when you need to complainto your carrier about poor reception in your area.► Find dead spots around your home/office that affect phone calls,but not data (or data, but not phone calls).► Reception quality can be misleading with bars only.
