[G4 General] Mr.Miyagi555:
Did anyone try out the OP's Nexus* 4 touch settings in the build.prop? and what is the #xTreme G4 TWEAKS i see in some of these build.props?

i was googling LG G4 build.props and came across this from pocketnow.

Another tweak that’s no longer used the way it was previously has to do with windowsmgr. Modern builds of Android lock the “smoothness” to 60fps. The FPS multiplied by 1.5 gives you the recommended value of this setting. Many sources still suggest setting this to 300 or even higher to help make things look “smoother”. That’s no longer the case, so setting this value above 90 (60 * 1.5) will likely result in higher processing demands with no visible improvement – and will probably slow you down.

windowsmgr.max_events_per_sec=90

Is there any validity to this? The OP has this line of code in the ##### touch related ##### section.
[G4 General] Animatorman:
They're settings from a Nexus 4 and I'm using them now.
[G4 General] chrisokaly:
I can say this definitely does SOMETHING.... Prior to the mod, the app "Yet Another Multi Touch Test" would crap out after 6 touches. Now i can get it to register all 10.

Will have to monitor if there is any effect on battery life, but so far, big time +1
[G4 General] AegisValour:
**** man, I'm failing at 6 as well. My device is not rooted as I was considering sending it back for warranty. Please let us know after some testing. I mostly want to know if the swipes registering as taps still occur as frequently if at all.
[G4 General] esmenikmatixx:
knock on seems to be working better for me now. im curious about the windowsmgr.max_events_per_sec=200

i was going to just put 90 because it made sense in what was posted earlier, but i figured better safe than sorry since im ls991 with no .tot to save me
[G4 General] mcnick0495:
Just curious, but anyone here using the H810 (AT&T) model, and applied these changes?
[G4 General] mdoctor:
Made a noticeable difference for me. This was a frequent issue for me, but after a couple of days with these build.prop settings, it has definitely improved, although the problem has not been completely nixed, these settings are a definite improvement. The knock-on taps work the first time almost 90% of the time (before it was about 50%). Also missed taps have greatly decreased, and swipes read as taps have greatly reduced as well. Many thanks to OP for making my G4 actually tolerable to use.
[G4 General] RedOCtobyr:
I'm not quite sure what we're testing here :) But I can get to 10 touches. Verizon, running 611A, no touchscreen tweaks done.
[G4 General] chrisokaly:
hey... try to lay the phone on your lap/leg and 1 by 1 add your index finger thru pinky on each side of the phone.... that is right index thru pinky on the right side of the phone, then left index thru pinky on the left side. one finger, one hand at a time. let me know if you get past 6. try your BEST not to move your fingers or the phone, and dont get too close to any of the edges
[G4 General] mcnick0495:
It's a grounding issue I believe. Not sure what kind of fix is needed, but I believe it could be done through software.

And BTW, mine bugs when I try it on a table or other surface, but when in my lap or touching my body somehow it works flawlessly.
[G4 General] uly609:
I have an H810 and made the changes. You can find what I did a few pages back
[G4 General] AegisValour:
I can say it's a little harder to reach 6 but that might be conditions of your test.

If I try it with a flat surface sometimes it fails at 6 sometimes it'll hold. The sides do seem a little off but the phone does rock. What were you looking for in particular?
[G4 General] rickmatic:
I thought of this with your post....:D
[G4 General] spartan268:
Tried this out. It made minor improvements, but it's still there.

My test is to have the phone plugged in and try typing. This always craps out my keyboard and starts registering some words as swypes and it's a complete disaster.

After using this, I had less swypes going on, but it still occured. BUT it was less frequent. So it's a start.

Or this could all be placebo.
[G4 General] Mr.Miyagi555:
What keyboard are you using? You could use something like swift key and make sure the swipe me is off. Totally irrelevant to the tapping issue, but would help you in your case with the swiping keyboard issue.
[G4 General] spartan268:
I am using swift key. Normally I like to use the Swype every now and then so the other hand is free to do my business. But honestly I'll take up your suggestion because the swype on swiftkey is absolute garbage. My HTC stock was amazing at it, but swiftkey just can't seem to get the pathing right. And the pathway I leave is spot on too.
[G4 General] bitbitbit:
I noticed a difference when I made the changes in build.prop. Wanting to make things even better, I started removing some of the lines and see what effects they have. I also did some research on the new lines. Seems like a lot of them aren't documented anywhere.

At the end of it, I am only left with a few lines and don't notice any difference from before when I have all the suggested changes. Here is what I have now

touch.deviceType=touchScreen

touch.pressure.calibration=default

ro.min.fling_velocity=8000

ro.min_pointer_dur=8

I am not even sure if the first two lines make a difference but from reading about them on android.com, it doesn't look like they will hurt anything so I kept them. fling_velocity makes a major difference in scrolling speed. I am not entirely sure if the last line makes a difference either but I am thinking it may reduce accidental taps (when you are actually trying to swipe) so I kept it too. At one point I thought touch.pressure.scale was making a difference but from the debugging data, it doesn't look like that number was actually doing anything.

Just sharing my experience in case someone else want to tinker with the tweaks further. :good:
[G4 General] mrcrusha829:
I wanted to state that some of the issues that people are seeing are due to the light sensor on top of the phone when it comes to double tap to wake.

This is most likely the way LG intended to make sure that the phone doesn't wake up in our pockets. You can test out my theory by putting your finger across the top to cover the sensor and with your other hand try to double tap to wake the phone.
[G4 General] frankymix:
Yes i tried this and it's true. The light sensor does not let double tap to wake work if covered.
[G4 General] mcnick0495:
Proximity sensor, FYI.
[G4 General] frankymix:
Not really noticing much of a difference.. Will keep you guys posted.
[G4 General] Red_Baran:
I used the Nexus 4 and the "snappier" modifications and so far I see a nice improvement. But I have only run it for a few min, I will update again later. Thank you!
[G4 General] Milimbar:
No, ambient light sensor, same one that auto adjusts brightness based on ambient light.

No light = no touchscreen.
[G4 General] mcnick0495:
There's an ambient light sensor, used to detect your ambient light and adjust brightness automatically (given you have auto brightness turned on).

Right next to it is a proximity sensor. The same thing that turns your screen off when you put your phone to your head when on a phone call.

Double tap to wake works in a pitch dark room. So it doesn't use the light sensor, but rather the proximity sensor.
[G4 General] donbudafuko:
OK so I found this http://xdaforums.com/android/software-hacking/tweak-l-speed-v1-0-02-02-2015-t3020138 an there is a option for touch sensitivity an it works great...the mod itself works well still trying it out but so fare I can say I don't have any touch problems...wrote this hole thing with out a miss
[G4 General] Bootup:
and is missing a d...twice

far has an extra letter

whole is missing a w

a couple of periods/commas are missing

think you have at least 4 misses....
[G4 General] donbudafuko:
Thats just how I spell sry next time I won't post something I found that seems to me to be doing great with touch issue...
[G4 General] ZipAddict:
U r a hypocrite and quite rude sir. I was looking thru ur posts and spotted a few typos that u made too. Not everyone speeks english as a first language here or is even an adult. I speak english and still dont care about typing everything perfectly from my phone. Besides he was just trying to help people. Xda is about sharing knowledge and u just demotivated someone from doing that. Shame on u.
[G4 General] donbudafuko:
Thank you..I know I'm bad at spelling have been my entire life..its just the way I am...ya I was just helping an ya same here on my phone is the last place I try to spell everything perfect so it is miss spelled more then normal but ya ppl can't help just being rude especially these days anymore. Again thank you

Ps wrote this one with no misses as well...its so good not to miss what u push/type
[G4 General] woozzy101:
I assume you have a T-mobile or unlocked international G4? I'm getting missed touches on my Verizon G4 and looking of a way to tweak something that will fix it :(
[G4 General] Bootup:
Thank you, white knight. But, to correct you, I didn't say I missed any keystrokes; I know I type fast and miss things. Thus, your hypocrite statement is wrong. But if someone say they type a 'hole' thing with no misses and there are multiple errors that look like things are missed, that doesn't set a good example of a piece of software or settings they are recommending. Now, if his typing is normally like that, or his default language isn't english, then I can understand. But the point remains that he said he had no misses while typing but what he typed looked like there are plenty of misses. I just pointed that out. U kan step offf yo whyte hurse now.
[G4 General] donbudafuko:
No I am on us cellular an no unlocked bootloader...there is in the 3rd post if I remember right that has one for us that can't flash an then there is a app called flash gordaon http://xdaforums.com/showthread.php?t=2250555 that u can try..I am about to try it to use the new 2.5 test version 2 but reading on what I need to do before I do...
[G4 General] Red_Baran:
So after a day of use I can tell you I see an improvement but there is still a major touch issue on mine.

Sent from my VS986
[G4 General] Bootup:
Same conclusion I'm having...
[G4 General] ZipAddict:
if you guys are seeing an improvement with Lspeed mod's touch tweak, then you can tweak touch sensitivity even furthur by editing the build.prop. Just back up build.prop first in case you make a mistake. The touch tweak is clearly labeled with build.prop edits right underneath it though so it would be hard to mess up. This would theoretically improve it furthur. apologies if this has already been tried.
[G4 General] danaff37:
Been on the build.prop tweaks for about 24 hours... Holy crap what a difference! Thanks OP, working great here!
[G4 General] pettigrew95:
So I added this to the end of my build.prop file and then restarted my phone...Now I am staring at the black LG splash screen and the phone won't boot...Any way to edit the build.prop file back to stock if the phone won't get past the splash screen? Thanks.

EDIT: Had to apply the VZW 11a KDZ then re-root to get phone to boot again. I didn't have permissions set properly on the edited build.prop file I made. Once I corrected that I applied the touch settings in OP and can boot into phone just fine now.
[G4 General] danaff37:
If this happens to anyone else, simply going into download mode and following the rooting instructions from there should be enough without having to do a full kdz.
[G4 General] pettigrew95:
This would work only if you kept the rooted .img file on your internal sd card of the phone otherwise there's no way to get the phone into MTP mode being stuck at the LG splash screen.
[G4 General] danaff37:
Yes, true. Didn't think about that. Have left mine there just for this kind of thing... Hate not having recovery.
[G4 General] Akomack:
I believe I had the img file and wasn't able to reapply the image while getting the LG bootloop. I had to flash to stock then reflash the rooted img.
[G4 General] xoxey:
I'm on international H81510VD pre rooted firmware no touch issues,pretty good battery life overall smooth performance:)
[G4 General] Barsky:
Just made these edits to my build.prop. The phone does seem more responsive. Thanks
[G4 General] shadearg:
Easy as pie. No misses or accidental taps now, even entered my complex pattern perfect five times in a row. Night and day difference; thank you very much.
[G4 General] Snakecharmed:
This seems to be a big improvement, although only time will tell as I keep testing with it. The screen does seem to be more responsive. Missed taps are greatly reduced and long-presses are more reliably detected. I still don't think it's perfect, but the screen responsiveness isn't aggravating anymore.
[G4 General] Spectre51:
Where did you find these on the nexus 4, was it in the build.prop? I'd like to see what my Xperia Z3 Tablet Compact is set for as I love the scrolling speed and fluidity of the Xperia devices.

Sent from my LG G4
[G4 General] Snakecharmed:
One hour later, there are a lot more misses. Business as usual.
[G4 General] shadearg:
I'm still getting occasional misses and accidental taps as well. The tweak is definitely an improvement, regardless.
[G4 General] bobloadmire:
So I copied the build.prop over to windows. Added the 2 sections at the end of the file, saved and overwrote the one on the phone. Bootlooped. Had to flash KDZ to boot again. What happened?

This definately ain't my first rodeo with build.prop tweaks, but it is my first bootloop.
[G4 General] kbuck13:
I had the same results today but used es explore
[G4 General] GUGUITOMTG4:
Use Notepad ++. don't use the regular one (Notepad) It modifies the file. move the build prop via adb pull/push and do chmod 644

Always copy-paste original build prop onto another folder as backup.

adb pull /system/build.prop

Edit it. With Notepad++

adb push build.prop /system/build.prop

chmod 644 /system/build.prop

adb reboot

If your G4 has TWRP, you can also fix it by moving or pushing the original build.prop to /system
[G4 General] kbuck13:
Thanks I'll try that, I have VZ G4 and we currently have root Only.

[G4 General] kbuck13:
Thank you again[emoji2]
[G4 General] pettigrew95:
Did you set the permissions on the build.prop back to the original permissions? I forgot this step and it is what caused my bootloop.
[G4 General] kbuck13:
What are the permissions supposed to be?
[G4 General] esmenikmatixx:
rw- r- r-
[G4 General] Beerukoff:
Could you please write the final version of the code which I need to add in build.prop?

Thanks in advance!
[G4 General] FadeFx:
Thanx [MENTION=6847891]shbang[/MENTION], i am currently testing, however, this wont cure my main touch problem, coming from a samsung s3 i have to get used to the navbar below the keyboard and i often justmissthespacebar... ;)

---------- Post added at 11:13 AM ---------- Previous post was at 11:10 AM ----------

Id suggest to just edit the build.prop directly on the device using something like es fileexplorer. This prevents any issues like that and saves you some steps.

[G4 General] joshuadjohnson22:
I have the AT&T H810 on H81010e and I cannot find those lines in the build.prop even when I do a search... Did they update it in this version? I haven't noticed a lot of misses either but was curious to give it a try.
[G4 General] FadeFx:
You are supposed to add them.

tapatalked from lollipopped i9300
[G4 General] joshuadjohnson22:
Alright I added it, let's see if I notice a difference. Thanks
[G4 General] madmaverickmatt:
Wow, I have been meaning to try this for a few days now, but I just jumped the gun and did it today, and I definitely see an improvement.

Thanks.
[G4 General] mcnick0495:
Anyone find any other changes or lines to add that help? I was gonna try these next and see what I get:

debug.performance.tuning=1 - (Increases touch responsiveness)

video.accelerate.hw=1 - (Increases touch responsiveness)

And did anyone try tinkering with the values for the #####touch related##### group? Trying to make the fling velocity greater (like on stock/nexus), cause its not quite there yet with these values.
[G4 General] bobloadmire:
ahhh that had to be it, thanks!
[G4 General] fishman0919:
Edited with Notepad++... copied to /system with Root Browser.

Fix permissions with Root Browser (important or you will bootloop... I think this may be the problem some are having.). All's good.

Noticeably better screen response.

Double-tap to wake better.
[G4 General] kbuck13:
Yep worked like a charm for me that way also
[G4 General] billybong10:
So far this is working great for me.
[G4 General] rav101:
Really appreciate this. I have just added to my build prop and so far the phone seems very responsive. I will keep and eye open over the next few days to see how this progresses and report back. I had just done a factory wipe and fresh install of the Version C from autoprimes zip file which also seemed to help.
[G4 General] joshuadjohnson22:
I still have a good bit of misses, it's really starting to annoy me.
[G4 General] FadeFx:
Open the build.prop file with es fileexplorers editor and safe it afterwards, no extra steps needed, no permissions to repair or something else. Just hastle free...

OP has been working on optimizing the touch tweaks. Hopefully he will post it up soon[emoji106]
[G4 General] marriux2:
Gonna try this right now.... thought I didn't have any touch screen problems until I tried playing Geometry Dash.
[G4 General] shag_on_e:
Okay shbang, I can confirm your settings are working amazingly for me on my Verizon G4. Touch is super responsive and I barely have to tap where I used to have to tap hard and in most cases more than once(or twice). Thanks for sharing and I'm following closely for any new findings.
[G4 General] chrisokaly:
Something I've noticed; removing the back cover and holding the phone like normal with my hand across the battery, touch is flawless, whether I'm typing, swiping, scrolling, etc.

Leads me into believing the "grounding issue" theorists.
[G4 General] Weetbix:
Hmmmm - I just gave this a quick try - and it does seem to improve things. Interesting...
[G4 General] DsturbD:
Which back covers do you guys have and do you have any cases on the phone normally?
[G4 General] chrisokaly:
Tmo leather for me. No case
[G4 General] Weetbix:
Just the standard plastic back cover on my H815. No case. Yet.
[G4 General] slowsuki1:
touch screen problems

just got sprint lg g4 and was having touch screen problems not registering touches soi installed a app called sgs screen booster setting super optimized and it has fixed 90% of the problems i was having.
[G4 General] DsturbD:
so same issue with either back cover, there goes that thought, but yeah im still thinking some kind of ground issue or connectivity issue like others have stated

wow you should post that as a review, that app hasnt been updated since Feb 2012 and was only meant for Gingerbread :good:
[G4 General] DsturbD:
yeah i just typed my response wrong, i was just wondering if there was any difference in the 2 types of back covers, if you both had the leather cover, then we would need to find someone with the regular cover who may not have any touch issues, but i guess the phones been out long enough that if that were the case, we would have known by now...oh well, so much for my theory :)
[G4 General] slowsuki1:
if you read the reviews you will see that it has worked for lots of people with diffrent device, you should try to have open mind and try something before you try to discredit it, if it does not work for you fine but you do not have to be a **** about it ****.
[G4 General] konsolen:
Hi guys,

just my 2 cents. I look at the problem with the bad touch responsive on laying Phones since years. Had this since galaxy nexus. Fine that iam not cracy and more people notice this. I use the h815 with the 10d firmware and also this Problem. Back is the plastic one in normal version and the one from LG with the circle on the front.
[G4 General] cubexg:
Just going to add my 2 cents. Was having the touch issue, driving me nuts. Rooted, added this to build.prop and WOW what a difference. So far so good - very happy! Thanks! On Sprint G4 w/ leather back.
[G4 General] Spectre51:
Finally gave these a try and must say it is much better. A lot smoother and it has cut down on the number of accidental taps instead of swipes.

[G4 General] laurasaurisrex:
I disabled the LG Keyboard. Instantly, my problem (edit: the missed/lagging touches problem, which is what this thread is for) was solved. :good:
[G4 General] Mr.Miyagi555:
? What was your problem exactly?
[G4 General] DsturbD:
Wasnt being a ****, ****. I was serious in that you should state in a review of the app your experience in using it to solve an issue. It was a positive post by me, you just read it wrong.
[G4 General] laurasaurisrex:
Edited my post to clarify. Have been having issues myself with double-tap to wake only working half the time, pin/typing mistakes, missed touches, etc. Heard that LG's update to fix the issue had to do with an update to the LG Keyboard, which apparently did have results? I have not wanted to update because I want to stay on the original version in case of a potential bootloader exploit, so I tried to find the updated apk for the keyboard. But then I realized I don't even use the keyboard, I use Swiftkey, so I tried just disabling it and the keyboard's black theme apk. Restarted, and was able to tell the difference immediately. The touch lag is completely gone.

Sorry I failed to explain in my original post. I'm tired and I hit Post too quickly without really thinking about needing to provide actual info lol.
[G4 General] Mr.Miyagi555:
Thanks for clarifying. that's the first time I've heard that freezing the lg keyboard fixing a tapping issue. placebo or not ill give it a shot.
[G4 General] Cobthaich:
Do you guys know how to disable the lg keyboard. I'm using google keyboard and lg keyboard shows but I can't edit it, it's check marked but unedtiable, grated out. I tried de bloating but not in list. I can stop it in the apps section but can't disable? Any idea why?
[G4 General] malnash52@gmail.com:
Download an app called uninstaller and delete the LG keyboard its ****
[G4 General] laurasaurisrex:
You'll need to use Titanium to freeze it.

No problem. I'm very certain that was it, at least for me. 24 hours later and a couple restarts, and the improved touches have persisted, and it's an extremely noticeable improvement after being annoyed by it for 2 months. The "button press" animation on the keyboard/lock screen pin pad, touch vibration, touch sounds, etc no longer feel like I'm trying to type through mud.
[G4 General] joshuadjohnson22:
I also did this yesterday before I read your post. It fixes the keyboard lag issues but I still get about the same amount of misses as I did before. At least I can type now without stupid lag.
[G4 General] DsturbD:
This plus SwiftKey ftw
[G4 General] daddymikey1975:
Is it possible to do this without root?

I'm on sprint, haven't rooted yet due to lack of a kdz to go back to stock in case I bork root.
[G4 General] spartan268:
You can grab the debloater app from here and use that instead as well. It works for both root and non-root. It's exactly what I did instead of using titanium

Thx for the info, trying tonight
