    Default 4G slows down my phone

    Even after I turn it off it remains slow. If I don't use it there is a faster response time in browsing and flowing through the screens. Anyone else? BTW I am not rooted.

    Are you imagining it maybe? It's usually slow for like 10-15 seconds as it scans but if you turn it off it shouldn't effect the phone in that way. Do you have a CPU monitor so you can see if there is some app using CPU?

    Yep, it absolutely does. Even after you turn it off it lags for a little while. Makes the phone damn near unusable with it on.

    Sense, your statement doesn't make any. Are you telling me the main feature of the phone that's marketed (4G!) makes the phone useless? I was using 4G in Hawaii during my vacation the entire time and here in L.A. whenever I have signal. Sure, scanning slows the phone down a little but not when it's on.

    My phone slows way down when 4G is turned on too.

    Here's my experience:
    - phone runs perfectly fine and smooth with 4G OFF
    - turn on 4G and connect to 4G signal, then phone is laggy/slow/unresponsive, even when sliding between home screens
    - turn 4G off, and phone still behaves slowly
    - rebooting phone with 4G off and things are fine again

    My EVO is on stock 2.2.

    For those that are saying they never experienced it or imaging it's happening...are you guys in 4G area and tried it? I might just take a video showing my phones behavior.

    Normal CPU usage. It's really noticeable when I switch between screens.

    Mine was doing the exact same thing for a while. Watchdog Lite showed "IO" using 70% of the CPU. It seems to come and go though. Hasn't happened in a while.

    I'm having the same problem since the last OTA update. When I turn the 4G on it creates an insane amount of lag when swiping between home screens or scrolling pages/photos. Even if I turn 4G off and wait 5 minutes or so, the lag never goes away. I have to restart my Evo to get it to act normal again. I hope this gets fixed soon.

    Looking at my log with aLogcat, I see a lot of these msgs after I turn off 4G:

    E/Wimax ( 98): <DC CONNECT> IO error: msg='/127.0.0.1:7771 - Connection refused'

    They recur every couple of seconds. I Googled "127.0.0.1:7771" and found a number of references, all seeming to indicate issues with 4G still scanning and trying to connect after being turned off. Examples:





    Does this contribute to the sluggishness I see? Does it contribute to the faster battery drain I see after turning off 4g? I do know that if I reboot the phone with 4G still off that this problem is gone after restart.

    4G lags for me but only when it's on a single bar (maybe it's changing from 3g to 4g back to 3g?)
    and also turning on and off 4g.

    this issue has been noted in multiple threads here & on phandroid

    the reported problem is that AFTER you turn on the 4g radio, and it scans--regardless of whether it finds network or not, and then turn it off--IT continues to scan UNTIL you turn off the phone. boot it back up & it won't repeatedly scan.

    user opened up aLogcat and noted the error stating something about the wimax connection refused, reattempting & refused---repeatedly. that accounts for the lag you're experiencing. the phone is constantly searching.

    search the forum and you'll find the post.

    Does anyone know if Sprint or HTC are aware of this problem yet? I'm thinking this will be fixed soon since the 4G is one of the Evo's biggest selling points.

    See the links in my earlier post in this thread - those were from June and July so this has been around for a while.

    I have noticed sometimes that enabling 4G causes the OOM (out of memory) kernel function to kick in. It keep killing a wimax authentication daemon of sorts. Even after turning off 4G it keeps going at it. You can verify this by typing "dmesg" in the adb console and seeing messages about the OOM and typing "free" to see how much memory is in use.

    This happens to me also. But I will say not every time.

    Add me to the list observing this behavior since the last update. WTH?

    I just tried turning 4G on/off and my phone didn't even react to it. Just a few things:

    1. I don't use any task killers
    2. I still have not run the latest OTA
    3. I don't overclock
    4. I don't have a live wallpaper running.

    This happens to me as well. But, indoors it runs fine. Outdoors it slows everything down.

    I'm saying it makes the phone almost unusable when you have it on because it lags so bad.

    I will say that I don't recall it doing that when I first got the phone. Only after awhile did I really notice it.

    I'm on 4g right now, and the UI is running like molasses. Press an app icon...wait 5 seconds for anything to respond. Swipe on a home or browser screen...wait another 3 seconds before the screen starts scrolling. Even as I type this, the letters don't show up on screen until a couple seconds after I've pressed the keys. This is embarrassing. One of the Evo's killer features has been emasculated.

    To add insult to injury, it REMAINS laggy even after you turn 4g off! I'll take 30fps and blistering 4g speed any day over this crap. What good is 60 fps if I'm only seeing 10 fps, and the phone responds like my old Palm Pre with 20 cards open, while on 4g?

    I'm updated to the latest OTA and it still didn't make a difference. My phone is fast regardless if 4G is off, 4G is on or 4G is in between the middle.

    Well, I re-started my phone and reenabled 4g. The only other thing I did is update my PRL. No issues again so far. I had fallen asleep last night listening to tunein radio on 4g. Only other thing I know happened last night is Lookout doing a backup. Woke up to what I posted above. I'm wondering if Lookout or some other app is causing problems.

    Well, if the issue gets big enough, we can trust HTC to fix it! (Darn Samsung! Why have we only got one update?)
