In this video you will learn how to troubleshoot mobile operating system & application security issues.
Signal Drop/Weak Signal
The easiest way to mitigate a signal drop or a weak signal on a cellular device is to simply move to a different location to pick up a stronger signal or adjust how you hold the phone. If cellular connections are good outside the office or home but poor inside, a cellular repeater can help improve performance.
Power Drain
If a device has the screen brightness maxed out in addition to having too many apps running at the same time, that could result in the device having a power drain. To mitigate a power drain issue, simply dim the screen’s brightness & close out apps that are not being used. When a cellular device is out of range of a signal, placing the device into Airplane mode will also help to minimize power drain.

Some of these apps are legitimate and offered in Google Play or the App Store and they are usually marketed towards parents & organizations that want to keep tabs on the individuals using their phones.
High Resource Utilization
