I got a new Android phone, and have some queries about it.

I have some apps that came pre-installed, and I see no use for them. I did not see any way to uninstall these though. Is there any way to uninstall them, or, they can only be uninstalled if I root the phone, or, they cannot be uninstalled at all?

Also, I am really baffled by the apps that keep running in the background... I really cannot understand how they start by themselves, and how to handle them.

First is about the task manager. When I open task manager, under Active Applications, I see none running... but when I go to RAM... and then tap Clear Memory, I always find 3-4 applications being closed, and freeing up memory. Why is that? Why don't these apps show up under Active Applications?

And even after clearing memory, and the apps getting closed, after sometime, I again see memory being used like before... and again on clearing memory, 3-4 apps get closed. What's happening?

I installed Avast Mobile Security, and Advanced Task Killer... with the help of them, I can see many apps running in background. I kill them from there, and they still start themselves up. Really baffled.

If I listen to some music, or watch some videos, and when I close them, via Advanced Task Killer, I can still see them running. Why is that? Don't they close when I click on the back button on the phone? If not, what's the proper way to close these?

I see Google Maps running all the time. If I kill it, it starts again. I am not connected to internet, and I don't have the need for it.. so why does it run? Is there any way to stop it from running all the time?

Same for Email.. I haven't got an email setup, but the process still keeps running.

Is there any Startup Manager app for Android, where I can take control of what apps run automatically on startup, or, any app by which I can configure which apps I want running, and which not. Anything like that? Because I really find all these apps running all the time a real trouble. Further, if I get internet, and I install more apps, and if they all keep running all the time, with no proper way to handle them, it's going to be a trouble. That's the thing that I did not like about Android... very little control over all these apps.

And I had connected my phone to the internet for a while... and found everything just connecting to it, specially the Google apps.

To connect to Android Market, I had to set up Gmail account on phone, and now I find my contact list has filled up with contacts from Gmail http://www.techsupportalert.com/freeware-forum/images/smilies/eek.gif .. and that's really irritating. I now have to wade through an ocean of contacts, to find the one I want... geez! What more can you expect from Google http://www.techsupportalert.com/freeware-forum/images/smilies/rolleyes.gif . Any way that those contacts won't appear?

Thank goodness that Facebook app had the option of not syncing the Facebook contacts with phone, otherwise the list would have been more :$.

There are some shortcuts on my home screen. Accidentally, and I don't know how, I managed to drag a shortcut of an app on to the home screen... any idea how to get rid of it?

Well, I think these will be all for now... more later.

Most of your questions are related to Android's multitasking and memory management. See my comment here (http://www.techsupportalert.com/best-free-android-apps.htm?page=1#comment-86383) and useful info about 'Multitasking the Android Way (http://android-developers.blogspot.com/2010/04/multitasking-android-way.html)'.

To remove a shortcut from your home screen, touch and hold its icon, then drag it to the trash bin. That's it.

Thanks for the links. That answers some of my questions. Still, I am not fully convinced with their apps-running-all-the-time theory. Although, it seems like Android does have good app handling capabilities... still, options should be given to fully close an app, if a user so chooses. Letting apps linger in the background, even if one does not intend to, does not make sense to me.

If they can bring an app to its previous state, even after it was killed and closed, then why not provide the option to close it after all.

There should be more control over apps and processes in the hands of the user.

The other day, I turned on my phone to watch videos, and I found that the music player had switched on automatically, and sound was coming. I was quite perplexed by this, and it actually took me sometime to find which file was playing. And I had not used the music player since a whole day. It was quite surprising that it loaded itself on automatically, as soon as I plugged in the ear phones.

Ah! Got it now. Thanks. I now also got it, that if you tap and hold on an app icon long enough, it automatically gets itself on the home screen. That's how the icon must have got there.

I still don't understand the apps and processes working fully though. I am still confused as to why certain processes/apps run even when I kill them. For example, certainly music player should not run, once I killed it from task killer app.

Is there any kind of startup manager for Android?

One other query is that, I had to forward a long sms to my friends. It arrived as a text messages, and in the properties of the sms too, it shows as text. However, when I try to forward it, it automatically gets converted into a multimedia message. Why is that... and how do I stop it from doing that?

I copied the text, and bought it to one sms matter, by editing it appropriately, but still, it does not get converted to a normal text message. Is there any solution to this issue? I had no such problems with my earlier Nokia phone.

Also, my Nokia phone used to nicely show the sms delivery report, and also stored it in a separate area to look at it later. But with this Android phone, the delivery report display is really bad. It just flashes it in the small notification area of milliseconds, and also does not save a report anywhere. Not good for me. This, I find a problem with.

The best explanations that I've read regarding Android background apps can be found at Lifehacker. 2 articles in particular that I really liked and I think should be read by every Android user are:

http://lifehacker.com/5795796/how-to...-android-phone (http://lifehacker.com/5795796/how-to-get-better-battery-life-from-your-android-phone)

http://lifehacker.com/5862994/real-w...-still-useless (http://lifehacker.com/5862994/real-world-test-show-that-android-task-killers-are-still-useless)

Here's one more:

http://www.pcworld.com/article/24406...tery_life.html (http://www.pcworld.com/article/244067/taskkiller_apps_will_they_help_or_hurt_your_batter y_life.html)

Oh....and probably the best yet:

Wow... some nice articles there... great reading. Thanks a lot Kendall !

Good to know that task killers are not good to use, and don't really offer an advantage. That was nice to know, when I am just starting to use Android.

Anyways, I didn't use task killer for preserving battery, but more for the purpose of clearing up RAM, as I thought that keeping RAM free is good. Well, this is what we Windows users tend to do. But, an article says that its actually good having a full RAM on Android. Hmmm... will not exactly agree to that... but from the articles, its clear that Android manages the processes itself. Still, as I mentioned earlier, I think there are some chances of improvements on that... as far as I feel now... maybe I am wrong.

The tips about tuning off wifi, or bluetooth etc, are good.. and that's the ones I have been following by my own. Why to have them on, when you don't need them. Tip about having power control widget on home screen was a good idea, and I will do that.

Also good tip about not using too much of fancy stuff, like live wallpapers. While they look awesome, they use up lots of power.

Really some good reading there.

So, the pre-installed apps cannot be uninstalled until we root the phone.

I heard from my bro that rooting can sometimes cause problems.. is that true? Or, its the opposite? Of course, that question does not involve the risk of bricking the phone... which is quite an obvious risk.

Because, the Lifehacker article says that rooting is actually good, and they recommend it. I will do more reading on that later.

I am not too keen on rooting my phone right now. And of course, there is always the risk of bricking my expensive phone at the back of mind http://www.techsupportalert.com/freeware-forum/images/smilies/eek.gif

Got things to learn today.. great!
