    Anyone experiencing any issues with multi tasking...I read a few things prior to getting the phone and now that I have it. It's hit or miss..sometimes it will bring me back right where I was..and other times it will reload the page...tho in "recent apps" the picture shows where I last was...

    In the words of Isn..sound off below!

    I haven't had any issues with mine. It takes Mr right back where I was. With the exception of the Phandroid app. That always defaults to the home page.

    if you "back out" of an app you are closing it out. if you just tap "home" or go to the pull down and access something else (an alert or somesuch, etc), that app you left should be right where you last left off from it.

    if you have moved on to other things, after a while, the OS will see you have not accessed it in some time and then close it out (even if you had left it running in the background).

    this is standard Android. some of you must not be used to Android and how the OS works.

    HTC Sense 4.0 is really agressive in killing background tasks. That's why the OP is concerned.

    I know how android works I've had it for years.... When I reenter the app it starts over.. Not all the time but sometimes.... I was told that that's how they want it to work and sense is aggressive when killing apps.. But in no way am I a newbie to android

    ok well if you understand why its doing it then whats the issue exactly? :confused:
    and i am not trying to say you are a newbie to anything. i dont know your experience with android hence why i made that statement.

    so we know the OS can be aggressive with some apps and lenient on others.

    would rooting the device and cooking a ROM change these characteristics?

    OK, I find this terribly interesting. It's a reply to htc evo 814 in response to his issue about Sense restarting - a related action, because in that case, Sense is bailing to make room for apps, instead of vice versa.

    Does that mean that there is an easily accessible way to tune it??

    Very interested to see if there is...

    The dev options are a cool thing to see on this phone Btw.... Makes me want to learn more about android and try my hand in development

    A custom kernel can really make a difference. On the GNex some devs enabled zram which lets the phone keep even more apps in memory so they don't have to reload. It works great.

    Interesting indeed.
    "Don't Keep Activities" was a solution/troubleshooting step to a few One X problems I recall reading.

    It is not totally customizable/tuneable. :(
    Though right below the option to "Don't Keep Activities" you can set a "Background Process Limit", click it and you get the limited choices of "Standard Limit", "No Background Processes", and "At most 1 process", ... 2, ... 3, ... 4"

    We might be able to get to the set points via System Tuner and root, but until custom recovery and full nandroids exist, I think fiddling with those would be insane.

    I can confirm that the Evo has the same aggressive memory management issues present in the One X. Sometimes even the Sense launcher gets killed when i've opened enough tabs in Chrome.

    Same thing for me, although I haven't been using Chrome all that much, but definitely happens when I have several apps going. The first few days I didn't experience Sense getting killed and relaunched, but it has happened a couple times in the last 24 hrs.

    It hasn't become unbearable or overly annoying .... yet.

    I still love the phone overall though.

    I'm a Rhapsody user and there are issues getting the Rhapsody app to play in the background. I'll start the app, play a song, hit the phones home button to send Rhapsody to the background. Then I'll move on to other things, Facebook, Reader, and then Rhapsody will just stop.

    I've brought the issue up to Rhapsody, just letting others know.

    Google Play Music acts as expected, never closes when in the background.

    Anyone else having problems with the System Panel app? It keeps turning off and on by itself (or could be crashing, but no Force close notifications). So it makes monitoring and history kind of out of wack.

    I could never get it to monitor, only show current stats.

    This is an issue with the aggressive memory management of the LTEvo/One X -- apps are much more likely to get killed and it looks like the monitoring of SystemPanel App is falling victim to that.

    1) You can set SystemPanel App to "high priority", which requires that an icon show up on the taskbar. However, the memory management is so aggressive here that even a high priority thread can get killed. I can personally demonstrate this where I would go into Chrome browser, start opening links as new tabs, and then eventually the SystemPanel App icon will just disappear from the taskbar.... outrageous.

    2) Strangely, my personal solution was, in addition to setting SystemPanel App to high priority, to get rid of using Sense altogether. I switched to ApexLauncher for my homescreen, which I found to consume a lot less memory, and inexplicably, SystemPanel app has not been killed as of late.

    Let me know what you guys find.

    Root users can try Viper rom, it's tweaked to make task bailing less aggressive.

    Are you suggesting that replacing the Sense Launcher with any 3rd party launcher works around the aggressive mem management issue?

    I assume people wanted aggressive memory!? Early android day's people wanted to why app kept running!
