Can I put a S4 smartphone into a flatbed scanner?

The various carriers added a bunch of programs after they got their hands on the phone. They also decieded not to allow you to uninstall them, hence you can disable them, but not delete them from your phone. This will stop the ones you disable from showing up in your app drawer, and running in the backround.

As for a list for the factory install apps, your going to have to google that question specifically with which carrier you have (Verizon, ATT, Sprint, ect). I also remember reading a good post on the XDA forums from that listed all the apps you can disable without causing problems.

I saw many apps inside gear icon>more tab>application manager>downloaded. Does it mean that these icons are downloaded by my cellphone provider? I just bought the phone and I did not download any app yet.

How do I see which apps are from android, which apps are from samsung, which apps are from my cellphone provider?

In gear icon>more tab>application manager>running, how do I know which apps are started to run by the phone and which apps are run by me? Did I forgot to stop running some apps or should these apps be running at all times?
For example I see over 20 app under running such as Maps, Samsung WatchOn, Weather Widget, McAfee Security, Filter.
See all my apps under "running":

In gear icon>more tab>application manager>all, i click once to select the app. Some of the app have a "Uninstall" button, some of the apps have a "Disable" button, what is the difference of these apps? Why are they different?

Thanks

Sometimes certain apps cannot be uninstalled because they are usually bloatwares that are attached to your firmware. The only way to get rid of them is to root and use titanium back up.

Do you guys frequently need to go to gear icon>more tab>application manager>running to shut down things there?

 

[Sizzers]

Essentially just go through your pre-installed apps in Settings>Apps and disable what you don?t want there.

If any of them show ?Uninstall Updates? rather than ?Disable?, then select this then the ?Disable? option will show up afterwards. With apps you've installed yourself then this option doesn't apply: if you no longer want the app then simply uninstall it.

Actually I was try to ask if I need to access swipe down>gear icon>more tab>application manager>running and click the app and click "stop", after using an app.

I heard that an app is not fully closed if I exit the app by clicking the back button (bottom right of phone), not sure whats the right way of fully closing and app.

Usually nobody goes to swipe down>gear icon>more tab>application manager>running to "stop" anything? Unless system hangs?

Android works differently from iOS and windows. The android system uses the ram efficiently and it won't hang unless it is really overloaded.

For the 'back' button part, that is how I usually exit my apps all the time

I found this thread kind of odd...so I tried it. You get the phone but not the screen. I guess the glass reflects too much.

As stated Android does a pretty good job of handling things however if you want to make sure an app is closed. Click your home button to go to your home screen. Then hold the home button down for a second, you'll see all of your open apps listed. You can swipe them to one side to close them and they will be removed from active memory. System hangs are quite infrequent these days and if you have one, you'll probably be pulling the battery rather than trying to stop an app.

You can close all your apps by holding the home button down for a second and hitting the x on the bottom right. Or add the task manager widget to one of your home screens.

I agree there isn't any general reason to close apps. Android keeps them in RAM so they'll open faster the next time you want to use them and closes stuff if it needs RAM for an active app. They types of memory leaks I've seen in Android usually aren't fixed by closing apps, anyway. You have to restart or clear the cache partition if you want them fixed (and I haven't had to do that on the S4 yet).

There may be specific reasons to close apps, though. I find that left unchecked, browsers tend to leave a lot of tabs open when accessed from different apps, so closing them down from time to time is an easy way to close all those open tabs you don't need anymore.

Do you mean usually nobody will bother closing apps by going to "apps by holding the home button down for a second" and close apps there?
It is best to leave them open there so the app would open faster? So it is some sort like the apps inside home button there are in a "Standby/Sleeping" mode?

I do not really notice a difference in speed of opening the apps regardless if it is inside the home button or not.

Here's how I understand it; When you exit an app, it doesnt shut it off, it simply pauses it, usually. The next time you open it, it just starts off from where you left off, and since the app doesnt have to start over again, its usually a little quicker transitioning between things. Once your cache of apps gets to the memory limit, Android clears out the oldest programs from this cache. The problem is that sometimes an app doesnt pause completley and will be eating up resources in the background.

Personally, I habitually clear out my task list every time I'm putting my phone away, though Ive read this actually increases battety drain because Im continously reloading the apps I use often.

Yes, in a way...
Every time you are in an app and then you want to do something else, don't do all those steps. Just press the home button and do whatever you want to do next. Also, you can just press the back button to go back to something else.

Yep. It's not so necessary to close apps.

My guess is that it's a bit more complex than that. Some apps that require information from the internet will periodically update themselves so that you don't have to wait for the most up to date information (e.g. weather apps). I haven't messed around with killing tasks since Eclair or Froyo so I'm not sure how it works now, but some apps will just automatically open themselves even if you close them, anyway. There used to be this big debate on whether or not it's worth killing tasks (which used to require a separate app), but anymore my guess is that it makes so little difference that it doesn't really matter what you do. If you're happier compulsively closing apps the worst that will likely happen is you'll have to wait a second or two once in a while.

My observation after a month and a half of having an S4 is that either memory leaks aren't as prevalent or having so much more memory makes them seem less prevalent than what I remember from Froyo. I haven't had a rouge app go crazy and drain my battery or use up all my resources like what used to happen on my Droid X2 running Froyo, and that was pretty much the only time I ever forced close apps.

I have the habit of press the home button for a few seconds and then clear all the apps. It doesn't affect my phone in any way. It is clearly just preference.

After removing that app, did your battery life get any better?

Isn't Battery Guru supposed to help with saving power instead of making it worse!

I recently downloaded that app, 2 days ago it stopped learning and begun to help saving battery juice. So far I can't really say if it has made a difference on savings, but it is definitively not working against me as it happened to you!
