[SOLVED] No Knock-On/Knock Code - G2 Q&A, Help & Troubleshooting

After toying with ROMs I've noticed that knock-on went missing on my G2 D802. Same for Knock Code on ROMs that claim to support it (and worked for me at some point earlier).
Some googling revealed that it could be related to bad touchscreen/proximity sensor error.
However, this is not the case: during call the screen turns off and on correcly, not getting stuck after call etc.
Touch works perfectly as well: dragging notification center at any point, could fill the screen in draw app with a single, long stroke.
Flashing to stock KK using this guide, then resetting to factory settings (which took reeeeally long, like 10-13 minutes. Also scared the cr*p out of me because I thought I bricked it ) didn't help as well.
Has anyone encountered such issue? If yes, how can I deal with it?
Maybe some way to enable sweep2wake instead? I'm really fine with ANY gesture to wake that works.

Slider unlock sometimes doesn't work with incoming call

Once in a while when trying to answer an incoming call the unlock slider won't respond. I will slide my thumb to unlock and ...nothing. When this happens the call will just go to voicemail . The workaround is to touch the power button to turn off screen , then touch it again to wake it up ,then the slider will work and I can answer the call. Sometimes this takes too long and I miss the call.
This is not a deal-breaker as it only happens 5% of the time , still it is annoying. I have tried different roms with no real difference. Anybody else have this problem? Any advice other than get a new phone under warranty?
Ditto. And I always act as you did to work around the issue, only difference is, I haven't missed a call due to this.
In any case, based on experience, the chance of this happening could be minimized (if not eliminated) by always locking the phone from the "desktop" (e.g. do not lock the phone when an app is running).
BACK STORY:
I remember this happening (more than once) when someone called me up after a train ride. And the last thing I could recall is that I have locked the phone while playing Angry Birds / Fruit Ninja / Zenonia 2, etc.
But it still sucks that it happens.
I guess my real question is , are all Nexus s doing this sporadically , even rarely , or is my phone defective?
question... are the phones plugged in to a wall charger when this happens?
Nope. Only happened to me when I under clocked the CPU with Setcpu using the powersave profile (I was just testing things out).

I'm not sure if everyone's having this, but I'm with you on this. I'm on stock but rooted 2.3.3. Experienced this since 2.3.1.
EDIT: My wife has this problem too, since 2.3.1 until 2.3.3 (not rooted).

Mine did it stock , I rooted and loaded roms to see if that would fix the problem , lessened but still there
My nexus s (i9020T) has exactly the same problem. I've also tried to flash different ROMs, including CM-7rc2 and stock 2.3.3, and the problem remains.
I tried to bind Multi-touch Visualizer 2 to long pressing home button, and found the when screen is unresponsive, it can still detect press near edges very well, but not the center. While I press at the edge and drap across the center, it keeps tracking my finger correctly. In addition, Locking and unlocking the screen can solve the problem temporally. I connect my phone with adb, and tried to "cat /dev/input/event0" The behavior confirms what I see in Multitouch Visualizor 2: the when the center of screen is unresponsive, nothing can be read from the device node.
I read the mxt224 touch screen controller doc, and it seems the chip features self-calibration, and thus I believe the "lock & unlock" will trigger the chip to tune it self in some way. I've also read the driver code of nexus s, htc incredible and moto droid x, all using the same controlling chip. Both HTC and moto would send calibrate command to the chip during resume, but sumsang does not. I guess this might be the reason, but I'm not skilled enough to port the drivers
I experienced it twice so far i think, but only have the device for a little more than 2 weeks.
I am on stock 2.3.1 currently.
Beside the lock&unlock method, I discovered a new way of getting screen back to work: rub your hands a couple of times and touch again... Anyway it seem the screen is not well calibrated.
problem seems fixed with my customized kernel
Last night, I modified the touchscreen driver and mach settings a bit on the source of netarchy's nice kernel, and compiled a kernel of my own. The screen now seems working well with my new kernel
Never have experienced this on the nscollab rom which is cm7 and kernel together stable. I suggest give it a shot

Dell Streak 5 various problems

Dear all,
i have a Dell Streak 5, with following specs:
Android Version: 2.2.2
Kernel Version: 2.6.32.9-perf
Build Nr: 15609
The issues are:
- If i use the phone on my pocket with screen to my leg, when i need to unlock screen, i usualy can't, its kind of crashed...
- If i have the wireless ON, and go out from home, usually phone crashes , and when i go to use it, i see there was a reset. Seems that this wireless is kind of instable and make mobile phone crash.
I would like to upgrade something to try to solve this small issues, can anybody help me?
Thank you
Tiago
I forgot:
Baseband Version: GAUSB1A135100-EU
thanks.
I don't know what to tell you as far as wifi crashing your phone. That's never happened to me. As far as the other issue, seems pretty common. I think the recommended "fix" is to not carry it with screen facing your leg. I'm sure that's not what you want to hear....but its the best I got.
i can't explain why you wifi makes your phone crash, but for the impossibility to unlock the screen. i had the same problem, and somebody told me the problem was the heat of the leg that makes the screen tilt. so i bought an otterbox case with a belt clip, so with the screen untouched it works perfectly.
for the screen against leg issue, I just toggle the power off then on and it works.
yes, i agree to lordmorphous, don't face your screen to your leg..
just in case, you may try to calibrate it, or if the problem still, maybe you can re-flash to another latest stock rom.
I have never experienced the screen issues involved with facing the screen towards my leg, and I always put my Streak in my pocket with the screen facing my leg. I guess so far I've gotten lucky.

The ROM makes no difference. I run 360 on my Streak.
I met a guy in a train station, and since there are not a lot ppl with such mob, i decided to ask. In fact, with screen faced outside, the issue finished. Strange..
Related with stock ROM, i think this is my next step: upgrade! the process dell.com.blablabla is always crashing, and sometimes i need to wait to use the phone. awww, not to say that i can't synch with my outlook
I am a bit disappointed with this phone/tab, i was expecting that it could work better.
Any tips on ROM? I am actually trying to use titanum backup to backup data, but it says again cannot root! How i root it?
Thanks again.
Tiago
Everything You Always Wanted To Know About The Streak But Were Too Busy Bricking It
That link there is your first step, for it explains how to root and how to do various other things. Now...I tend NOT to recommend using Titanium Backup since in my experience it screws up when restoring items. Your mileage may vary.
As to a ROM, stick with a stock ROM for now until you are comfortable with the rooting process. I have attempted to use GingerStreak but had a problem with the camera app so I had to go back. Flashing a ROM could fix your issues since a bad flash has been known to be source of the force closes.
Hi again,
finaly i tried a simple method: the gingerbreak, and rooted. Now that is rooted, i want try a diff Android version (from 2.2 to 2.3?).
Is there any recommendation?
Of course first i would like to backup all the data (already from the SDCard) but i am talking about the ContactList (i tried to use the simple: export, but onde again i got an error :/)
Any tips?
Thanks for all the help.

I've been having lots of little problems too.
My device randomnly decideds to restart time to time. There doesn't seem to be a pattern to it that I've worked out yet. But it's crashing right now and I have to soft reset it.
Another thing, if I have it in normal landscape mode but turn it on while holding it portrait mode or the screen isn't in the same orientation that it was before the screen turned off, Dell Stage often crashes.

Exactly, mine restart very often too, but i think i know why. Try disable wireless before leaving your "home network"... in my case, it solves that crashings... only crash if dell stage crashes too... but most of times, its solved.
The only "bugs" i have are: camera button does not work, and when i turn screen on, the "unlock slide button" is ALWAYS in the portrait position.
I wonder, if this is solved with a new android version, or dell "libraries" update?
Thanks.

for all those who think the problem does show up when u put it in the pocket facing your leg ..... i had the same view two weeks ago when suddenly i ran into this problem. i think best solution is calibrating the screen .....

Calibrating the screen was what i've done when i could not unlock my mob phone for 1 week, i was desperate
After that, i solved all the screen issues using screen outside and not against leg.

[Q] Knock on just stopped working?

I've had my G2 for almost a month now and the knock on/off always worked flawlessly. Then today it just stopped working, my knock off works but knock ON will not work, at ALL! I've restarted, turned the feature off/on, nothing is getting it to work again. Any ideas? What exactly triggers the knock on feature? Surely it can be the touch of the lcd if the screen is off...is it somehow the proximity sensor or gyro sensor? If I can figure out how it works maybe I can start there..Thanks for any help you can give me.

Backup first...then Factory reset
Should fix whatever file or resource that got screwed up. Install your apps 1by1 until you find what app caused your issue & delete it

Well I havent installed anything new recently but maybe I'll take the opportunity to try one of the new CM/ASOP roms...Thanks for the reply
I'm having the same issue with knock on not working. i've wiped a few times and have flashed diferent roms but it wont turn the phone back on. i'm also having this strange issue where i cant pull the notification bar down.
EDIT: I figured it out. did you install TWRP Recovery? i did and mine was messed up. i flashed back to stock and re-rooted and everything works again. I'm not sure if TWRP is the reason since im on a t-mobile G2 but reflashing to stock definitely worked. also i think you have to do a reset after flashing rom because the changes wont take effect unless you do

Wow that's a relief, I'm having the same pull down issue too.. Even scrolling here is a dead spot on the screen if I'm scrolling a page or list as I get in that area it "slows". I thought my digitizer was going bad. I found my knock on works but I have to do it extremely slow... Tap... Pause 1-2...tap.
Edit yes to twrp.

well i re-rooted and it doesnt work anymore. i deleted stuff so i need to see if its something that is being removed that causes it to not work
I just flashed the stock rom back..shows unrooted again, and it is still doing the same thing. Im still under my 30 days, Im going to return it, hope for the Nexus 5 on verizon by the weekend and if not I guess buy a new G2.
mine still says rooted so i'm kinda screwed right now
Same issue
Same thing with my T Mo G2. Using Nova launcher. Knock on worked flawlessly since new, about 2 months,use Nova gesture for knock off. Suddenly knock on stopped working. Too bad, because I like the feature, got used to using it. Did a restore and wipe using TWRP, kept root access, but still no knock on. Next I'll try going back to stock ROM, but I'd rather go an easier route. Has anyone successfully restored knock on?
Hi i have a dead spot somewhere app in the screen and when i pull down the notification bar it doesnt goind down.Also i tryed to draw with quick memo and i can see that it is a dead spot somewhere near the top of the screen

No...first try this.
Open phone app and go to dialer
Dial 3845#*XXX# where XXX is your phone model i.e. 800/1/2/3.. You will come accross a menu.
Select settings
Select touchscreen firmware update...
Wait for couple of minutes...screen will become unresponsive...
when it responds reboot....
Go to settings gestures...ensure knock on is selected.
It should work then,
Let me know...Best of Luck....

I read the following posts on some other forum...so essentially its a hardware issue....try stock jb rom kdz, then factory reset and reboot. If this helps solve the problem you are lucky. If not, try getting your phone replaced with 802 model. That is practically most stable with a lot of devlopment and tons of ROMS stable and working.
I will still keep looking for a solution and let you know consulting a few senior xda devs I know... sorry man, it hurts to see a fellow indian in distress.....:crying:
Tons of lg users are experiencing this issue. Its a design flaw with a hardware component that easily breaks. Wonderful build quality -_-...right. So only option is replacing the phone. But to how soon, until the other one breaks. So its kinda like. Well. This blows. I suppose Ill install a custom kernel and enable screen wake features that way.

Also note, the standard two taps works sometimes, but with four presses, i seem to get the best results. Give it a try people. I have a theory the hardware has not failed. But yet, the activation area pixel size value changed. Either due to a conflicting app install. A intermittent system glitch etc

Good luck with that if the phone is a D800. I took my G2 to the local AT&T store just a couple of hours ago with the same "no knock on" bug. But the sales person (who had bad breath) told me that because there was another way to get the phone to function (the back button), they won't even look at it. The fact that the knock off/on feature was a MAJOR selling point when the phone was released is apparently irrelevant.
He has a ls980 so it might not be the same for him. He can ask for a replacement

This happened to me this week as well, unfortunately in Canada none of the carriers will replace my device for me, LG says its user damage and are gonna charge me 125 dollars to fix it. I'm gonna see what the local repair shop says and hopefully theyll just fix it for me. It seems like this is an increasingly common issue, it's a shame that LG don't recognize that we didn't damage our phones, they sold us defective units. I'm very unhappy with LG's customer service, we should raise awareness of this and hopefully LG will come up with a solution for us

Did you try the "Hidden Menu" "Touch firmware update" option? I had this issue and it got fixed with it.
try 3845#*modelnumber# eg: 3845#*800# change model number 800 with your phones model number, then tap on "Settings" and scroll down to "Update Touch Firmware"
I have a few more suggestions to make it work, let me know how it goes.

[Q] Sensors dead?

I've been running on 5.0 for about a week (stock, rooted). I rather suddenly had the tablet fail to auto-rotate, but rebooting sorted it out at the time. Now it completely refuses to rotate. Not only that, but every app I've tried that reports sensor data doesn't even acknowledge the existence of any input other than the touchscreen and the microphone. I've tried reflashing 5.0 to no avail, and I'm in the process of going back to 4.4 to see if that does anything but I'm not feeling hopeful about it.
Does anyone have any ideas of what else I could try? I'm pretty sure it's well out of warranty (rooting aside), so I'm not sure how feasible it would be to get support on it from Asus. I'm considering popping it apart and seeing if anything obvious is wrong but I'm not sure what I'd be looking for.

I had same problem with my N7 2013. First: I opened the back and secured a lousy cable, closed, worked almost 1 full day till everything stops. I also used my book case with magnets. Then: I reopened, secured the other side too of the lousy cable and closed. No case till this, 5 days are passed and no error. So, due to my flaw in the modus operandi, now I don't know if it was for the cables of for the case with magets. I hope the second, I won't use that case either anymore :laugh:
Hope this can help (even if I have the 2013 version)
I have exactly the same issue. My Nexus 7 2013 is on 5.0.1 and rooted. I nnoticed the issue yesterday. First alerted by screen rotation not working, I used CPU Z to see if the compass was detected and I found the sensors page completely blank.
Any help would be greatly appreciated.

Touchscreen issues solved after 05Q update

I was one of the unlucky persons to deal with the dreaded touchscreen problem. When on the 44s build, it sometimes got so bad the phone was almost completely useless. The touch screen problems didn't go away in spite of flashing countless Rome with almost every possible combination of kernels.. But nothing seemed to help. The touchscreen got noticeably worse when the phone got hot..i was almost at the verge of giving up.. But that's when it happened.. The 05Q update solved all of my touchscreen problems. I've checked with touch Explorer and even multi touch works flawlessly.. I understand that this problem was identified as a grounding defect.. And I did buy it.. But since the 05Q update seems to have completely solved this issue, my faith in oneplus has been restored.. Did anyone else notice this? What could be the reason?
Nothing's changed for me :c
Sent via Telnet
I never used to have problems with the touchscreen, but since update, the double tap to wake sometimes doesn't work.
It's really annoying to have to try it several times when you want to check the phone. (I already got used to not using physical buttons).
Anyone else with this issue?

For me, it got better. I would have terrible touchscreen problems.. I wouldnt be able to wake the device via D2W and mostly resorted to the wake up button.. but ever since the update, the battery's been a little bit on the downside..but the touchscreen problems have been completely eliminated and i'm okay with the tradeoff.. I just dont understand how they've managed to fix it if it was a hardware issue? im greatly confused..

Glad to hear it is better for you. Unfortunately, I still am experiencing ghost touches... Double tap on the other hand is fine.
For those who are still having touchscreen issues.
I wasn't having any issues at 44S. OTA update to 05Q and I immediately noticed issues with 'fast typing'. None of the hacks online worked ex. cat some touch-screen related system file..
Looks like 05Q is legitimately slower performance-wise and at least to me the keyboard is unusable.
Anyway, I spent quite a bit of time on this. Updated to a CM12 nightly and it's gotten a lot better although the issue is still there although less noticeable. Just try typing 'this' quickly. I get a swipe gesture activated once in a while (vs pretty much 90% of the time on 05Q).
02/23 Nightly CM seems very stable and clean. Very usable

From my experience I could say that these 'gost touches' are related to a system slowness more than a touch problem. Sometime I feel I could type fast without any problem, sometime I had to type very slow. Also this is rom related. Some are really snappy others not so. Another thing to mention is that keyboard feels better after a reboot, so maybe a memory leak!?
Inviato dal mio A0001 utilizzando Tapatalk
I just hope it's not the hardware touchscreen / sensor. My observations are consistent with everything you mentioned above. Memory leak feels possible or some unoptimized code. I don't see any issue in ex Chrome. It's mostly Hangouts app that's super slow so perhaps Google also pushed some update to Hangouts that slowed things down enough to be noticeable.

I wasn't having any issues at 44S. OTA update to 05Q and I immediately noticed issues with 'fast typing'. None of the hacks online worked ex. cat some touch-screen related system file..

Same here - things were perfect on 44S, but screen has just turned to crap on 05Q!
Did you try going back to 44S, or did you just go straight to CM12 nightlies?
Cheers,

I went straighten to CM12 nighties. The touchscreen issues still does up but not as much. Makes me think is a hardware issue with the touchscreen independent of firmware perhaps just didn't notice before. When I went to CM12 I did a full wipe, so everything from scratch

Yup, definitely noticed DTTP is not working as well on 05Q vs. 44S.

I think I may have found a solution! Recently I enable the touchscreen buttons, but yesterday I disabled the quick launch shortcuts and it seems to be working.
Go to DEVICE - Buttons and disable it there!
Hope that helps!
I have not faced touch screen issue.
Even i have broken my display from top..

Hey,
Which touchscreen buttons do you mean?
I made a short video showing the problem using a multi-touch test app. Basically if I have two or more touch points that are horizontally near each other, the screen totally flips out!
Thanks,
Su

Crazy stuff.. Looking at the video, I have almost bought that it's a software problem..
Mine works fine if and only if you turn off all those double tap settings (wake/sleep) and turn off ambient display.
I've gone through all the settings menus and turned off everything gesture or touch related... also switched to onscreen buttons.
Still have the same problem
I emailed support to arrange an RMA, but they want me to wait for Lollipop... WTF?
