Can't multitask - RAZR HD Q&A, Help & Troubleshooting

Hi guys. I have a xt926 model with a .15 update and rooted. I am having problem with apps closing in the background. It is irritating especially with the chrome browser as it always takes me to the home page whenever I run the app. I only leave it in the background for 5 seconds that it just restarts. Is this a bug or is it because of the RAM? Any fix for this?
Thanks

I'm having the same problem, both under ART and Dalvik.
My old device, the Droid Bionic XT875, would run Pandora, Navigation, and Ingress simultaneously, for a couple hours, before one would stop. As a side note, it would run very slowly and would drain the battery slightly faster than the dock could charge it. I was using CM11-M12, and before that CM10.2.1.
My XT926 on 183.46.15 can't run Pandora and Navigation at the same time; within seconds whichever is in the background will stop. Switching between Chrome and Nova Launcher or Chrome and Tapatalk will stop the background app (also losing a post I'm composing in Tapatalk, which is frustrating.) I've disabled plenty of bloatware, including everything from Motorola, and the only unidentified things running in RAM are a couple qualcomm processes, and they're not very large. I've verified that "background processes" in developer settings is "Default".
The XT926 has the same amount of RAM as the older phone, plus faster processors and, theoretically, a more robust (stock) ROM.
I don't know why it's happening, but I'd love to make it stop.

[Q] Why do so many Apps restart after I use Advance Task Killer?

I'm currently running Infused 2.1 and noticing that my battery life is quite poor. I haven't used the phone much today but it's clearly draining faster than it was the last couple days when I was running stock Froyo. I have my brightness manually set all the way down, GPS is always off, Wifi is set to turn off when screen is off, no sync is active except 'Background Syncing' which apparently I have to keep on for the Marketplace. Only thing I've installed is Go Launcher EX but I can't imagine that this launcher would cause such a dramatic difference in battery. But I digress...
As to my question, I just ran Advanced Task Killer and killed everything running except ATK itself. I then waited maybe 20 seconds and upon launching ATK again, I noticed that I now have the following items listed. Why have all of the below items appeared again?
Facebook
Gmail
Market
YouTube
Google Search
Maps
Superuser
Kies air
WF & Clock widget

read this article so you will understand why you dont need a task killer with current android devices. if you search google or even youtube you will find many articles explaining how the os works
Interesting. Good read. So it seems like it's almost counter-productive to use these programs because I'll be honest, I've been using it just about every time before I lock the screen if I've done a bit of stuff on it. If it keeps reactivating these things to make the phone run faster, and I'm having it work harder by always killing them, then I can see that I might be contributing to the problem...
Appreciate the link.

[Q] multitasking failure?

"Apps start up instantly and switching between them is seamless. The dual core performance really comes to life when pushing your phone to its limits"
I have found that statement to be utter rubbish. After only just turning on the phone (fully, not fastboot), I only opened 4 apps, music,market,browser and messages. After about 5 minutes, when I tried to go back to the browser, it had to re-launch and it did it pretty much for all of them. Why is the multitasking so bad? even with sense it has 500MB+ for multitasking, the iphone handles multitasking MUCH better.
The Browser one is normal, it closes the tabs to stop it hogging RAM.
For me the multitasking works fine. The iPhone seems to have a 'stricter' method of multitasking that limits how and what apps can do in the background.
I'm guessing it gives priority to the pre-installed apps like Music, Messages and the Browser to stay in RAM. I'm not sure how other apps do with multitasking?

Weird changes in terms of speed

I've had my U11 (64/4 variant) for a month now. I'm satisfied with it in general, but I've noticed something really peculiar.
In the first days, my U11 was extremely snappy and fast (opening applications, opening the camera, unlocking the screen, and so forth). However, after using it for a week, I noticed a strange phenomenon: the general speed of my phone was changing all the time. I mean, sometimes, I had to wait approximately 2 seconds for Gmail to load & display my inbox, while sometimes I just tapped on Gmail and it loaded & displayed my inbox almost instantly. (No, Gmail wasn't in the RAM in the latter case...)
It's still happening and I'm not happy about it because I ditched my S7 due to Samsung's tacky and laggy TouchWiz (I heard that it had been renamed, but I don't really care). Don't get me wrong: I'm not saying that SenseUI is laggy and tacky because I love it and I haven't even experienced a slight lag since I had this phone, but the unpredictable speed of my phone is irritating a little bit. By the way, the same goes for the camera (stock application): sometimes, it takes quite long for the camera to load & be ready, while sometimes it doesn't even take a second.
More than 90% of the storage is free and more than 50% of the RAM is free most of the time.
What do I do? Shall I perform a factory reset? As I've mentioned, I'm using the stock ROM and I want to do so in the future, too as I've got used to it.
Htc Boost+ app. If you dont have it get it. If you do have it then check the foreground and background restrictions.
If you're using any apps from 3rd parties that control apps and ram, remove them. Android has it's own app killer and boost+ will do the rest according to how you use the phone.
Signal clarity is also a huge player in the speed of today's devices. If you have a weak wifi or cell signal then the phone has to wait for the data transfer so server connections will suffer, hence why you experience intermittent slow loading.
The camera may take a while because of not being in background or if other apps are consuming resources. Also the more you use an app the quicker it should open as android 'should' hold the app in ram, if theres enough room.
Hope this helps clarify.

Thanks for your reply. I had already used the Boost+ before I posted this thread. I deleted a few apps that I hadn't really used, and now I don't have any problems with my phone as far as speed is concerned.

How to track apps using CPU/RAM usage

Hello!
I'm sure this has been asked a million and one times but my searching only brings up results if I was the developer of an app. Guess my google skills aren't that great.
I have a Pixel 2 XL running stock android 11.X what ever we are up to now. For a while I have been having the phone running quite slow at times, laggy animations and freezes. Its not completely unusable, but what's throwing me off, is about 75% of the time it is like this, but the other 25% it runs smooth and quick, no lag at all, using the same apps I normally use. I can't figure out what is causing the lag the other 75% of the time, or what's different when it is running fast. Sometimes it takes up to a minute for Android Auto to load up when its lagging.
So what I'm asking is, are there any apps, root or non root, that I can use to more specifically see what apps are using CPU cycles or high memory usage? The battery usage in settings is only showing expected usage from my apps, so its not really helping.
Thanks in advance for your suggestions.
i'm looking into it too. so far, found none

The phone is very prone to killing background apps like music I'm listening to. How to make it stop?

Ever since the most recent updates, especially the Android 13 one (stock), I can't seem to multitask with this phone (A51). Browsing one or two websites with chrome it's too much for the poor thing, and decides to cut off background apps that I explicitely told him not to cut off.
So while browsing after a while Spotify crashes, Adguard crashes, the music player crashes, the youtube vanced playback crashes etc.
I don't have any launchers or actually use many apps, I have one messaging app and a social network installed but for everything else I try to use Chrome in order to save memory storage and give them a little less data.
It seems as if battery optimization is having a hard time with my phone (and I explicitely told it not to can Adguard, yet it still does), when it didn't use to. Any ideas? My phone's ram is constantly at 50% full, so there should be space for a few webpages. I disabled Samsung SmartRAM.
