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.

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:
HTC EVO 4G:Evo battery draining faster after update
4G reconnecting issue? - Page 5 - xda-developers
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.

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.

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.

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.

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?

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.
