Worked great before I installed 5.1.1 I just installed 5.1.1 on my phone and now System Panel only shows itself running. I can't look at how any other apps or system software is using my phone's resources. Of course, I can look at battery, network, CPU and storage info, but nothing else. Is that all this app can offer now? Sent developer e-mail and received no response.
Best App of Its Type! Very easy to use, very legible, processes grouped by Type (System, Inactive, Service Only, etc.). Just a really nice app all around, that gives plenty of info (tap or long-tap) and makes dealing with and/or killing processes super simple, with no guesswork involved! Removes the fear for those who are novices to using apps of this type! :-)
Perfect - Used it since beginning I've used this app since my nexus one and it's the one and only app that shows my usage and each app CPU usage, including system CPU usage. I take note specifically of idle periods and usually my CPU hovers below 0.5% total. Marshmallow seems to no longer show the cached apps in the main view, hope that comes back or gets added soon (hope its not an OS limitation with 6.0). This app is near perfect.
Needs updates It would be really great to see some updates to the app. More flexibility in the graph ranges and perhaps adjustment of the measuring interval. Some UI updates would be nice too including a white system tray icon. I have a Galaxy S5 and I use this app mainly to troubleshoot battery drain.
02/18/2016 - Excellent app which has withstood the test of time. I've been using it for many years now. I have not seen the "missing apps" issue that others have spoken of. However, I have noticed that on my Nexus 6P (Marshmallow), the icon doesn't appear in the notification bar like it does on my other devices (Sensation, Note2, Note4, Note10.14, etc.) Suspect this is a Marshmallow thing.
No longer works on my Nvidia Shield Tablet running 5.1.1. Still working on my Moto X 2013, but I've got a System Update waiting to be installed & doubt it will work after I install that. Was good while it lasted. My previous review was using an HTC Evo (the original with WiMax on Sprint o_O).
This release restores the major functionality of SystemPanel for 5.1.1/6.0 devices. It works around undocumented design changes in Android 5.1.1 and Android 6.0 which deliberately removed the ability to query information about running applications on a device.
