[Android 4.3] How to open app ops function

Android 4.3 has a hidden feature! It's called "App Ops" and it lets you selectively disable some permissions for your apps. Is some misbehaving app constantly pinging your location and draining your battery in a few hours? You can fix that now.
It's not really ready yet, so Google has hidden it. It seems to work though. You can download App ops Launcher from here, this tool is help to launch the hidden "App Ops" from android, but it only works for android 4.3.

Tap the icon and you'll see something like this. There's list of all your apps and the permissions they use, categorized into 4 handy tabs. The tabs are broken down into "location," "personal," "messaging," and "device," so it's easy to see what app uses the permissions you're concerned about. On the right is a timestamp for when the app last used a permission.
Once you pick an app, you'll get a screen with easy on/off buttons for each permission. Don't want Facebook to know your location? Just hit the "off" switch. The app will still work, it just won't have any idea where you are. This screen also tells you the last time each individual permission was used.
The one problem I see (and hopefully the reason why this isn't a user-facing feature yet) is that there is no explanation for why your location is broken in Facebook. A system notification that says something like "App Ops is currently limiting this application's permission access" would probably stop some tech support nightmares.
The way this list works is actually highly annoying. Rather than just read the declared permissions in App info (above), App Ops tries to do "detection" for certain permissions.
For some permissions, the app has to make use of them before they will show up in App Ops. For instance, on the left is my permissions list when I first fired up Facebook; in the middle is the list after I told it to import contacts; on the right is the list after I posted a picture from the camera. You have to go and hunt down all the permissions and make the app use them before you are allowed to disable them. That's a lot of work. Is this list complete? Will it ever be complete? There's really no way of knowing.
That's about it for App Ops. Just please, take care when you mess with this, and keep in mind it's not ready yet, so you might run into problems. Also, even when it does work, you are messing with settings the app developer never intended for your to have control over. If you happen to horribly break something, don't blame me!
And if you want to try to launch the "App ops", you can scan this QR to download and start it, enjoy yourself!

How does one ID what's using bluetooth and causing major battery drain.

Recently it seems that some badly written apps are trying to use bluetooth for beacons and are killing my battery in the process. In the past I found that Gasbuddy was the culprit and could work around the problem by killing it. Now it's happening again, The apps aren't showing up in the battery display but bluetooth keeps popping up as the second largest user of battery. For example, right now my phone has been off the charger for 3 hours and bluetooth is listing 32 minutes of CPU time and 1 Hour 19 Minutes of wakelocks. It never used to even show up on the list.
What tool can I use on a non-rooted phone to identify the app that is hammering bluetooth and causing that kind of usage.
Thanks for the advice,

I don't claim to know best non root or even best rooted rooted solution but I the short time I glanced at Google Play, this one caught my attention: no permissions or ads.

Attached is highest app regarding battery concerns. The Windows drop down but only option given is to uninstall. If there's an auto starts app that doesn't require root, that may be an alternative to add more control to these apps of concern.
I usually just use the Recents/Active applications to see what's active but you're right, there's activity hiding from this monitor. Only some are neglecting permissions.
Gee, I thought someone had said no ads in their review? Adaway adware scan didn't reflect this as a concern. Any doubt why I love root?

I don't know how well it works for non root phones but greenify now has an auto hibernation mode for non root users.

@poit
While looking for an Adaway alternative for systemless root, I came upon an app which produced a link for permissions app and ad blocker; both have no root requirements.
https://m.reddit.com/r/Android/comments/3vxa3b/managing_app_permissions_and_systemwide_ad_on/
You may have to search for the ad blocker but the permissions app is on XDA

I wouldn't recommend the auto installer unless temporarily enabling it for automated long process. I've used these rooted permissions apps but this one is very simple in approach although I had to ignore a lot of middle risk apps that I trust.
I installed both apps and scanned with no concerns. I'm liking the results so far.

Samsung "notes" app - running too much in the background

Hi all
As you can see in the image, the Samsung Notes app is running wayyyy too much in the background, eating up my battery. This is even after I make sure the app is closed after using it!

"lightbox_toggle_sidebar": "Toggle sidebar"
}
I tried to set the app to go to sleep, but this was not possible as it is a Samsung dedicated app. I couldn't even optimise this app either. The only solution seems to be "force stop"ing this app, which I prefer not to do as I use the app once or twice a day to write notes.
Anyone have any thoughts on how to stop this app from running so much in the background?

Possibly notes is trying to continuously update to the Samsung Cloud?

Thanks for your response, but nope - I've disabled everything from being able to backup to Samsung cloud

Personally I don't understand why the applications stay active in memory after I stop using them, since I can't tell the difference even if my life depend on it if apps is cold started, or starts from memory, either way it starts almost instantly, so yes I would definitely force stop it myself, especially that I feel this "feature" of all apps staying in memory is more for advertising purposes than anything else, especially now. There is a switch to either put app to sleep or not allow background activity, one is under apps inside battery menu, another under battery usage menu. I'm trying to limit all apps from running in the background, except for map which needs to be constantly updated for traffic, but what a pain in the neck it is, there are over 400 apps on the damn phone.

Disable or uninstall this trashware.
Switch to an app that stores your notes in a standard format such as text files etc so you can always read them in the future.
Finding a good free office app is now almost impossible for Android. I use an old copy of Kingsoft WPS Office. Today's newer versions though are pure crap unless you pay, pay, pay.
Used Samsung Notes on my S4 but restoring them became a tedious nightmare when I migrated to the Note 10 platform because Samsang "upgraded" their app so it wasn't backwards compatible with their older version's note files.
Don't trust Samsung with any data you care about; they will make it obsolete by their time table not yours.
Thanks for nothing Samsung... feel the wuv for the rabid gerbils in the box.

This is happening to me as well. I had the phone for 2 days and had the note 7 before with no problems. Anyone know why this is?

Fix drain after update miui 11

Can't see from pic but battery drain is NEVER normally happen. Did you it happened after updated. If the answer is yes
please check ALL notification and permissions on all app. Update may reset their setting and stupidly disabled all of them.
Most app need some permission that must be allowed but updates set deny their access, It make apps keep calling API trying to pop notification but updates disabled all notification too. See?
Basically all your batteries juices went to drain because ALL Apps doing these futile things.
IIRC Easiest way to fix is by first enable all notification (easily founded in setting page), then give setting AND security all access / permission they need. A lot of app will gives notification they need somethings now and grants them what they really need (Ie. Calculator asking for contact is suspicious AF)
This bug did happen in INDONESIAN ROM, may or may not apply to GLOBAL etv

It didn't work. Android system always consumes 30-40 percent of the battery
Hope the issue is fixed with the update

Question Digital wellbeing apk ? & problem with nova launcher

Hi guys !
I have been facing the known problem for a few days now.
This is that when I press the center button it keeps asking me to select Launcher .
I searched for this problem and read reports that the app is causing it Digital wellbeing.
In my case, however, the suggested solutions (uninstall updates, freeze app, clear data) do not solve the problem.
Here I should note that the application is pre-installed from the Samsung store, uninstalling it is not possible.
Do you have any idea that can solve this problem?

That's a trash app, worthless. Either use Package Disabler or an adb edit to stop it if you can't disable this app in settings.
Edit:
Just tested it on my N10+/Pie variant. It can't be disabled in settings. How thoughtless of them.
Use one of my first two options to take out the trash plus it removes it from the settings menu.
Another Google save the dumb bunnies, feel good parasite service. Gookill sucks.

Do you have any apκ (Package Disabler) to recommend me?

Sent you the link. Not on Playstore.

Ιn the end the problem was created by the application fitpro .
I found it completely by accident while looking for the solution to the reports I was finding about Digital wellbeing.
As soon as I uninstalled it, the problem was solved and everything now works perfectly as before.

DP makes finding buggy apps easier by letting you disable them on the fly.
The interactive widget let's you toggle one or more apps on/off.
