Double Tabing Issue (Knock on to wake up!) - LG V10 Q&A, Help & Troubleshooting

Hi Friends,
One problem which bother me a lot is knock on to wake up feature on LG V10. When I decided to turn my screen on as phone is on table, I have to use double tabs to wake up my phone and start using it. Sometimes it take 2 or 3 time of double tab screen to wake my phone up. You know, I have to try knock on feature twice or thrice to get in to my phone. This problem 60 % of time and it really annoying me a lot. It is worthwhile to say that knock feature for turning of screen is work nicely and 100 % of time without any lag. Is this a serious problem which I have to worried about?
Thanks guys.

This doesn't happen on my phone. When i tap twice it turns on every time. Maybe you can factory reset, and see if it solves the problem.

It happens to me a lot. It's not NEARLY as sensitive as on the G2/G3/G4. It takes almost 3x as many tries for me to get the Knock On to even work.

I'd estimate it to work on the first try about 70% of the time. Otherwise, I have to try again or a third time sometimes. My girlfriend's G4 has the same issue.

[Q] Screen just turn off. randomly

has anybody have this issue where your screen just randomly turns off?
and you have to hit the power button to turn it off.
i was using the music downloader app and i just touched the screen when it just went black. i had to hit the power button again to turn it back on.
oh and also i had my password set to 2580 just incase the finger print scanner didnt recognize it and it wouldnt take it. i typed it in about 10 times just scanned and changed it over again. just wondering if anybody is having these issues.
No finger scanner problems at all, and no lock pass problems either.
Screen do turn off but u can change that from settings.
Settings>Display>Screen Time out ( i am using 1 min, best for battery saving and dont turn off while usage)

yeah i checked those settings and its on the default 1 minute.
but it seemed strange that i had jsut touched it and bam went black.
There are only tow things i can think of.
1. U have a faulty phone.
2.Us battery is lose (try jerking around ur phone while screen is on, if screen goes blank and phone turns off then u know what the problem is)
if ur facing problem 1 then company warranty is only way, and if problem is number two wither sticking a piece of paper or changeing battery will fix the problem.
i had problem number 2 with my nokia phones quite a lot
One more thing try resetting ur phone to factory default, may be something u installed is causing problem.
I haven't noticed that it has done it. Just that time. But I got worried since its not even 2 days old.

[Q] Long power buton response time

I am absolutely satisfied with this phone . BUT i have one problem . When i push the power buton it takes between 0.2 and 2 secound to appear the lock screen. What should i do to make it faster? Becouse the waiting is disappointing with this hardware ....
if u want instant on u will need all of you 4 cores to stay awaken at full speed at all time u still want it ?
it goes to power saving mode thats why it needs 2 secs to be awaken

It's right , but my old desire hd had about 0.5 sec to wake up . This is why i asked it .
It's a battery saving feature. You can turn off S-Voice on lockscreen from the S-Voice settings, or just completely disable the whole application like I did, and this speeds up the wake process a little bit.

Yes i have already done that . But this lag is really annoying . Mainly because its not always the same ammount . Sometimes it takes 3 secounds but sometimes its a half secound. I really dont know what to do...
If your USB cable is connected, it wakes up instantly, if not, there is a lag. This is a feature (!) of Samsung phones. We discussed it deeply on this thread in SGS2 forum:
http://forum.xda-developers.com/showthread.php?t=1136223
Basically, it's epic failure by Samsung and there's no solution.
It can't be explained by saying phone needs to sleep, because HTC, LG, Sony, Motorola phones sleep too and none of them needs so long to wake up.
oh well in terms of when your actually using the phone, nothing compares to the speed and fluidity of Sammy phones. Isnt really an issue that it takes a second longer to wake up

Yes, but they also dont tend to have as good standby battery life on HTC, LG, Sony or Moto phones.
I'm not defending them completely but this is a design decision rather than a bug. That said, on the Galaxy Note it has been almost completely alleviated since the ICS upgrade.

I noticed it only recently after screwing around @ 1.8ghz that suddenly the phone is taking sometimes millisec or sometimes even 3 secs to go to lock screen and also ripple is slowed if immediately try to unlock. I thought maybe i messed up some part of hardware by o/cing it too much. Even my old LG O3D takes just a sec. ANyway glad to know it's a common thing and not my phone being fkd up.
I can't judge, I take several minutes to wake up.
Still waiting...

Thank you for all the answers!
Ive noticed this too, its frustrating, makes the phone feel laggy.
My S2 was running CM9 and that was sharp as hell, no messing about, is this something that will in time be fixed with a custom rom?

screen on delay on wake up

i recently exchanged my one x with galaxy s3
i have a problem that when phone screen is off (in deep sleep) (or 5-10 after last screen off) it takes around 1 second to turn screen on again
i.e when i press power or home button it takes 1 second for screen to show up
this was not a problem on one x or other phone i have seen
and i have tried many roms(all 4.4.4 based) different kernels etc
after searching i found that its samsungs deep sleep policy which sends phone into deep sleep and it takes a second to turn on hardware...
well i dont see many people complaining about this so iguess they may be not having this problem or solved their problem
is everyone having this issue? or only some unlucky like me?
is it any way possible to remove this delay with affecting battery life much?
It's normal, get used to it.

[Q] More like tap 5 times to wake?

Hi guys, just a quickie,
So I've enabled double tap to wake on my Z2, but sometimes it takes up to 10 taps for the device to wake up. Can a screen protector make the difference here? Or is it normal?
I notice the same thing sometimes. What I find is if the phone goes into a deep sleep (screen doesn't turn on for say 10 mins), it takes more than 2 taps to wake it a lot of the time. But if you turn the screen off, and tap twice within a few seconds, it works most of the time. Just my observations though.
Tapping a little bit harder works most of the time for me
Yeah it's the problem with deep sleep. I saw the same thing on many other devices. HTC One m8 and LG G2 Mini for example. Most of the time it's triple tap to wake
I found out that I was tapping way too quick.
Try tapping really slow, like once per second, and it almost works every time.
But it sucks because it is slow because of that, going to the power button is faster....
I usually just tap the screen until it turns on, but messes my PIN up good to know that it's not only my screen that's cold hearted to these poor little taps though

Delayed Wake?

Hey guys! Just got my g5 last week and have so far been loving it- fastest Android phone I've used, and a huge improvement over its horribly buggy predecessor. That being said....
I've noticed a crazy unlock delay, but only when it's right after locking it (sometimes I shut off my screen and am like "Oh wait! I totally forgot to do X). When I go to turn the screen on, it stays black for awhile, and then shows an unresponsive screen for second or so before unlocking.
Sometimes it's just an extra second, other times a good 5-10 seconds. However, if I lock the phone and leave it alone for even 20-30 seconds, the screen turns on immediately. Has anybody else run into this? Is this normal?

I use the tap to wake feature a lot and sometimes when I tap it it doesn't do anything and I end up tapping it again and sometimes again after that. On my note 4 I used the wake lock app on it because Samsungs are known for slow wake and I'm using that app now too. It's in the play store. Now the tap to wake never fails. Granted your phone never sleeps but I like it better that way and it seems more responsive too. Could be placebo but I think I actually get better battery life with it because when you wake your phone out of deep sleep all the components are firing back up whereas here everything is always ready. Hope that helps.

Hmm thanks for the tip I'll give it a shot! I guess I figured with the always-on display enabled that it should be able to wake pretty quickly? I do hibernate my apps with Greenify so maybe that's affecting it. But I only get like 3 hours of screen on time even when hibernating my apps.

You're welcome. Yeah with that app I just set it to partial wake lock and I have no issues with it and my phone works great. Good luck!

Sweet. Took the plunge and went for a factory reset, and it completely solved the issue. Im thinking it was Verizon's security update they pushed to my phone the night that I was setting the thing up. SO relieved
Oh wow. Made my battery life amazing too. I unplugged for 5 hours and still only at 86%
Well that's great. Waiting for sprint to drop their update and I'll probably do the same.
