Lock Screen bug - Nexus 4 Q&A, Help & Troubleshooting

It's happening every now and then, but sometimes when I press the lock screen button to unlock the screen, the lock screen comes up but I can't unlock it, it just ignores my finger like if the digitalizer was off. I have to press the button twice (to turn it off and on again) to make it work.
Any ideas?

Screen lock unusable?

With all that screen to touch, having this thing wake up in your pocket (or holster in my case) it bad - it registers keypresses all over the place, and so far it's deleted appointments and other fun stuff for me.
There is the screen lock (hold down right-most softkey a few seconds) but for me at least if an alert wakes the phone, the screen activates and looks normal, but all hardkeys are disabled. Can't even shut the phone down, have to hit the soft reset button, so conveniently located under the battery cover (argh, talk about dumb design choices...)
So anyone have any ideas on the screen lock? I'd even be willing to dedicate the left-most soft-key long-press to a third party lock, as long as it works properly.
u can use s2u2 IPHONE like screen lock
Hold the hang up button to lock, to unlock press the word unlock and a screen will apear saying To unlock device Tap unlock.
Yeah I did that, the hold hang up button thing... that's what's partly unlocking itself, which is a pain to say the least.
Gonna try Throttlelock. Haven't found any really Manila-lookalike skin yet but it seems to do what I want - lock the device - and even adds a little security.
And what about just clicking once on the power button after locking the device using the hold hang up thing?
Doesn't it does what you need? Press again to wake up the mobile?

No, what happen is: I hold down end call to get the device to lock. Then I tap the power button to close down the screen too.
However, a reminder kicks in and that brings the screen back online AND live, so touching it can do stuff. But, the device is still somehow "locked"... except the only thing that is well and truly locked are all the buttons. Power button, volume buttons, even the softkeys on the front, none of them do anything, but the screen works only too well.
There is now way I found to recover from that state except a soft reset. That boots the device - in locked mode, so I have to hit Unlock and then tap the button on the middle of the screen.
I need a lock that is lock, ie it doesn't activate the screen or buttons no matter what, until I unlock it myself. Looks like Throttlelock may be the answer though.

Home Button Issue (fixed)

I just got the Nexus S today. I've played around with it and love it so far, but I have one problem: when I press my Home button in an app, it doesn't throw me back to the home screen. It vibrates when I touch it (so it responds), but other than that it doesn't do anything. Also, my screen wouldn't lock or show the unlock slider (after waking up). It would just turn on to a home screen, even after setting a PIN lock.
Ok, so before I posted this message I decided to restart the phone. Home button now works, screen locks beautifully. Glad I don't have to go get a new one! Posting this still in case others have the same problem.
TLDR: Home button didn't work, screen didn't lock even with Pin. Solution: restart your phone.

Strange unlock behavior.

Given the positioning of the Nexus 4's buttons, it is not uncommon for the user to press the volume and lock buttons while attempting to unlock or lock the phone.
I noticed that on 4.3 and 4.4, every rom I tried, even stock 4.3. If the volume button was pressed when the lock button was pressed the phone would flash back to the previous screen state.
So if I wanted to activate the phone, pressed lock and accidentally pressed volume. The screen would wake and go to sleep right away, this would result in me miss tapping the off screen and pressing lock again where I risk repeating the cycle.
Or, in the anterior case. I would want to put the phone asleep, I press the lock, and accidentally hit one of the volume buttons resulting in the screen shutting off then quickly turning on and me putting down the phone with a lit screen.
Does anyone display this issue in their 4.3+ setup?

[BUG?] Screenfreeze on Mi 9T

Hi, I have recently purchased a Mi 9T and everything works fine with the phone, but I have this bug, that I didn't see in any post from this forum.
Every time the screens goes black (sleep), it doesn't recognize any input anymore. The phone still works and I can receive calls, notifications and so. I can turn on the camera, make screen captures, and everything, but only because I can do this with the volume and power buttons.
I tried Flashing the device, but when I get to the recovery screen of TWRP for the first time (where you need to make a swipe) the screens goes black for a second and doesn't let me do the swipe.
Any ideas of what the problem can be? (and the solution if it's possible).
If not just press the power button again ...same things happens to me, once i rebot into recovery it goes black and nothing happens, then i need to press the power button to "unlock" the screen again.
had similar experience: sometime after I lock the device (by hitting power button) and screen goes off, it input my finger on the fingerprint sensors it does not recognize and unlock (not even fingerprint animation actually). Other than this I can still hit the power button so that the screen lights up and then unlock with fingerprint.
But, this is just sometimes, not always.

lock screen never turns off

Hi guys When I lock my phone with power key the lock screen appears just after I release the key. And the lock screen never turns off!!! I tried to lock it again more and more with power key but the screen won't be turned off with any force. The screen appears just after I release the key. I don't know what to do?!! Noted that when the phone charging the lock screen goes off in very normal mode. I checked the timeout, smart stay, sleep and so more....
