Anyone have this problem ? Pulled my phone out of my pocket trying to respond a text msg . When I went to the lockscreen it was stuck and wouldn't respond to my swipe . Held the power button down to bring up the power menu. It wouldn't let me tap the restart button . Battery pull once n start , same thing at lock screen . Did it a second time finally let me swipe to open the phone . Freaking annoyed with this !

Mine does the same thing....

It is very annoying I dont know what to do i have tried different launchers, have used watch dog and monitored apps and nothing seems to work. Watch dog did alert me to some apps that i removed, but the problem persists.

I have a similar issue. However my message app also takes like 15 seconds to start.

If i use the task switcher button, then kill all aps, start messaging, it takes a while for it to actually open.

Now if the app is already started. And i switch back to it, either by pressi g the icon again or by the task switcher then it it responds instantly like it should.

I did not have this problem on the orig firmware and i did not have this problem initially on nk3 after updating. It just startrd happening about a week ago. Clearing messages did nothing. Clearing apps cache did nothing, claering apps data did nothing. Preforming a hard reset via recovery didnt even help with the issue for me.

Anyway, back on track. I have experienced what you are experiencing. Because i know when my txt msg app is "hung" for a few seconds. It literally causes the entire phone to become unresponsive until the app loads. Could this be what you are experiencing also?

I got the same thing happening. When I wake the screen, the screen goes dim, and there is no response. The phone just hangs. I have to pull the battery. The phone gets laggy from time to time and I have to reboot. It's like the ram is bogging the phone. I didn't have this problem before I updated to the the new update. Any ideas for a fix. Thanks in advanced.

Same here, a reboot fixes it for a short time but it goes back to lagging on the home screen. I used to use the FPscanner until it got so annoying, I thought that was the culprit. I put the lockscreen on swipe unlock and sure enough same lag and glitch. I think it has something to do with the apps open in the background. Also noticed connecting to wifi makes the phone stutter for a sec, so maybe the combo of unlocking the phone with a lot of apps running in back and connecting to wifi? IDK but this phone should def. not have this issue!
