LG G2 touchscreen sensitivity: fingernail - G2 General

Hello everyone,
Seems like LG g2 screen is not responding to nails. Or I'm the only one with defective unit ? Google doesn't answer this question.
ALso i have noticed that screen is not as sensitive as my previous samsung galaxies... i can always touch the screen very gently so it won't respond. It is a not too big deal for me, but it's interesting.
I have tried this with screen protector and without.
Your comments ?

Cut your nails. It gives better hygiene.

Hello.
You're right about the G2 not responding to nails. It has a capacitive touchscreen which basically means that when you touch the screen with your finger, your fingertip, which has an electric charge, disturbs the electrostatic field of your screen and thats what your phone interprets as an input.
Now your nail, which is made of keratine, can conduct an electrical charge but it's highly dependent on the water content of the nail, but a more important factor is the contact area between the screen and the nail. Since a nail touching a screen only touches very few mm^2 and a fingertip often touches about 0.5 cm^2 there's a big difference in the electrical charge that is transferred. Thats also the reason why if you touch the screen very gently you wont get a response either.
Final note: some phones require less electrical current to distort their electrostatic field thus registering a touch easier, and some phones actually have a resistive layer so you can use your phone with gloves. It's just not this phone.
I hope this helps.

Actually the screen is made very sensitive so that it can work with gloves on, nailbed, pen tip, pocket multi tools, knives!
U better return it and ask to replace the unit!

Yes Im also reading articles that G2 should work with nails and gloves on. Maybe it depends on carrier ?
Any other thoughts ? Does anybody having issues with screen not working using fingernails ?
I assume for girl with long nails this phone would not be usable :fingers-crossed:

you must have wet fingernail to response

Mine doesn't work with fingernails?

Knock on put the touch display always on, so the voltage is very low on LG g2, not like Samsung phone wich is more reactive, even with glows

[Q] A43 touch screen

Am I the only one having really poor touch recognition on my A43? Whether I use a finger or stylus, it often happens--about once in five keystrokes or more--that after releasing the touch on an on-screen keyboard, a different key additionally gets registered, sometimes not even a neighboring key. It is very hard to type in a password.
My touchscreen also has this problem. I'll hit one key and it will add another key somewhere entirely else on the screen. Menus will spaz out when I try and scroll through them.
Oh yeah, remember that problem I was having where strange spots showed up on the screen and I had to get it RMA'd? That came back on my BRAND NEW unit. I'm getting sick of the crappy screen on this otherwise great unit =[ Maybe Archos will just give me a refund and I can spend my funds on an unlocked/off contract phone with similar specs.
Sadly, I think this is a hardware issue. I'm not sure there's anything firmware can do besides ignore half of the inputs. But then, you have a non-responsive issue ...
Have you guys tried to calibrate the screen through SDE?
I have a similar issue with my A101, although it's not as bad as you guys describe - sometimes the screen just won't register my touch at all, mostly in the edges of the screen - sometimes I think it's the calluses on my fingers from playing guitar, sometimes I think it's the horrible screen they gave us....
My $0.02
So does anyone not have this problem with an A43?

You might be having better luck because the A101 has a capacitive screen with multi-touch capabilities. They're known to be more reliable than the resistive screens the 43IT's have.

I have a 43IT, which is why I posted Sorry I wasn't clear. I feel your pain. Also, I suggest using your nail or a stylus, as the pinpoint hardness of either are better than the soft, blob your fingertip makes on the screen sensor array.

I generally use a stylus. The problem is probably due to the way the plastic digitizer flexes which generates ghost movement data on release. A glass digitizer would be much better.
By the way, it is possible to ameliorate the problem slightly in software. I did that in the myKbd app for PalmOS. Basically, you filter out some very rapid motions. It doesn't affect sensitivity in any significant way.
The reason I'd like to know if everyone has this problem is because I'm going to send my A43 in for warranty repairs, and I am wondering if I should include this problem (in addition to the annoying bright 1/4" area on the screen, and the occasional timeouts when writing to internal flash that result in the device hanging).

[Q] [Active -St17i] Problem with screen when wet

Hi folks,
I have a problem with the screen of my Active when wet (eg. under shower). When water splashes on the screen (even small drops) my screen goes like crazy. It acts like I'm touching the screen with every single splash of the water drops. (It does this when screen is unlocked of course). It also makes it impossible to control with finger when drops are splashing. I started to think that wet finger control is a sort of scam.
I've imagined listening to music and be able to use the phone while in shower before I purchase this rugged phone. However I see it impossible now.
Is it some sort of a mulfunction? or it is supposed to behave that way. How does yours behave?
BTW I have the screen protector on that came affixed with the phone.
Thanks!
It is my understanding that the nature of the screen itself is such that working with water on the screen is not efficent. The reason why is that a capacitive screen acts by charging the screen with electricity and then monitoring the change in this charge as you touch it.
Water, just as your fingers, can absorb the electric charge on the screen and the screen would detect that as a touch. Therefor with some or much water on the screen it would be rendered unuseful (as the water would make the phone detect false input, as long as its on the screen).
There is however the possibility that this is not the case, but if so I am not aware of this. Possibly you could try some alternatives to controling your phone in such conditions when the screen is not useable.

If that is the case what SE referring to as "Wet finger tracking" is? They must have done something so that the water on the screen does not effect (at least that much) the control.
After all St17i is a rugged and waterproof phone. Or at least I bought it because it is.....
Dude I'm sure it is waterproof.
Don't u c a difference between waterproof and frigging underwater capabilities... I say u ask too much maybe I dnt ask enuff
Sent from my MB870 using XDA App
It is my opinion that there is a noticeable difference from using your fingers on the screen when they are wet from using your phone while in the shower.
Even so, I don't really find it as a very big downfall. The reason I'd buy that phone is not it's ability to resist water damage as the possibility of throwing it at people without it breaking easily. But that is just me perhaps..

Touch screen unusable in "wet" conditions?!

I S-OFF`ed my EVO 3D, flashed a custom recovery and a custom ROM (LeeDrOiD's latest), so I'm not on stock (if that's what's causing this).
Back in January, when it was cold outside (5-10 degrees), at times, after extensively using the phone outdoors (like 15-30 minutes), once I went into a warmer place (warmer by a few degrees Celsius, like 5 or so), the touchscreen was completely unresponsive. I could only lock or unlock the phone, but was unable to do anything else (which means using the touchscreen or capacitive keys, for that matter). I figured it may be because the screen was very cold or something...
I had to wait ~30 minutes for it to recover!
I figured that has something to do with the screen being somewhat covered by a very thin layer of water/ice or something... which rendered it almost completely useless (I was still able to drag the lock ring up a milimeter one time, out of ~20 attempts ).
----------------------------------------------------------
Now, it's almost April. It's warm here, alright, which means no more moisture outside (regarding the temperature, at least).
But there was drizzle outside yesterday, and I had to text someone. Several tiny water drops landed on my phone's touchscreen (not too much, covering like 1 centimeter in lenght), and the phone began to register mistaken touches...
The same happens when I try to use my phone with my fingers BARELY wet. I have to wipe the screen ENTIRELY to make sure it's not registering 10105909 touches all by itself...
This is ridiculous. Not even the HTC Desire (which had only 2 multi touch points, and even those, not so accurate) didn't have this problem! Nor the Desire HD.
Am I the only one?! Are you experiencing this, too?!
Same

As far as I know there is a small current running on top of the screen. Any kind of moisture will make your screen go crazy. Thats why I use a screen protector, because my sweaty hand dont play nice with any touch screen phone like the Evo 3D

As a matter of fact, I do use a screen protector. I've used MOMAX Anti-glare, MOMAX Clear, and right now I'm using a no-name crappy sheet that makes the screen look all wavy and shyte... I'm gonna apply a MOMAX Clear again soon.
Still, that's not the issue. Screen protector or not, the issue remains.
If you ever had such problems, please tell me what device are you using. CDMA, or GSM (for Europe - golden or for US/Asia, like me - red)?!
Same here, even when screen is completely dryed out.. What can we do about it?

I cleaned the screen with my blouse after I've been playing on it outside for 30 minutes. Cleaning did nothing...
Yesterday, it was raining. Not too big rain drops, but I let about 20 of them to cover the screen, some were little, a few were huge. The screen performed wonderful (in the time I tested it : scrolling across the menus, typing a fast message, probably less than 20 seconds).
What the hell...
---------------------------
NO responses?! Come on, I can't be the ONLY guy this is happening to !
There are 2 common types of touch screens. Resistive, which respond to flexing a thin sheet of plastic, and capacitive, which responds to an electric current. Resistive is not accurate so no one really uses it anymore except on knock off Chinese tablets. We have capacitive touch screens, same as apple products and every other popular android phone.
Any kind of moisture will interfere with the touch screen. Even if the air is very humid. There isn't much you can do if you are having those issues. And all electronics have specific temperature ranges they will function in. I don't know what the evo is rated for, but I'm sure it's somewhere.
Best advice is to keep dry. And no, a screen protector won't do much to help.

I know... I just thought the 3VO might be faulty, since, as I said, the Desire and the Desire HD never had this problem only with a few water drops...

[Q] Touchscreen sensitivity

Hi - If I touch the screen *very* gently, it doesn't register as a touch.
Does anyone else have this? If your P9000 is OK, please let me know.
Most of the time it's OK, but it's extra annoying when I'm swiping a long word which gets split into two smaller words. I do have the screen protector on - Obviously I don't want to remove it just for testing, but I realise it might be affecting sensitivity.
Over the years I've had ~5 phones with capacitive touchscreens. This is the first I can touch without it the phone 'realising'.
Thanks, Richard
PS - I've enabled the 'Show touches' in Developer options. The accuracy is fine, it's just it's not quite sensitive enough.

i have similar problem because the glass folie is on the phone. Im sure because i used without too... but I rather use like this..
So the screen protector made your screen less sensitive?
What phone do you have? The Elephone P9000?

yes, i have glass screen protector on my p9000 and it makes the digitizer less sensitive..
Thanks NX82. That's good news and bad news !
I want to have a screen protector, but sometimes the phone doesn't recognise/acknowledge gentle taps on the screen.
I'll try one other screen protector, if that doesn't work, I'll ask Amazon to replace it.
Cheers, R.

Yes. my screen also less sensitive with the screen protector, but i dont want to scratch the phone, so i rather use with the screen protector.. for me the less sensitive areas are around the edges of the protector.. but i can live with this problem. I know if i remove it gonna be okay again.. maybe possible to put a thinner folie on the screen and thats gonna be better. the protector glass is a little bit thick. probably this is the problem.
I also experienced a reduction in sensitivity after applying a glass screen protector. Without it phone always reacted okay, but with my protector the first miliseconds of my touch aren't registered it seems. I have more trouble typing and sometimes swiping lags. I have adjusted my usage and can live with it now though.
Yes a screen protector can make it less sensitive. But all I did was download this : https://play.google.com/store/apps/details?id=br.shop4apps.touchscreenbooster.com
And then set it to super optimised and make sure it runs at boot and problem solved.

Hmmmm... I've just tried reinstalling it.
No joy for me. Sensitivity is no different.
I set multipoints to maximum of 2 and rebooted but it's allowing 3.
I live in hope, though!

Hi. Yes I'm using it on my elephone p9000 right now. I didn't need a reboot tbh. So not sure. Could be a fiffy touchscreen you have in yours?
i installed this app too. i did not resatart the phone. maybe i feel a little difference, but hard to tell if it really helps or not. i have to use few days to tell its placebo or not

Well see how it goes and hopefully it does the trick. The p9000 glass isn't anything special. Don't want it to crack or scratch so we need something to protect it.
I have tried several touch calibrarion apps.
It seems like the restart is necessary to apply the new settings.
for me this application gave the best result:
https://play.google.com/store/apps/details?id=redpi.apps.touchscreencalibration
...and i still hoping its not just a placebo effect

same here : no effect
I have the same problem but all the above apps don't work for me. I will try to swap my screenprotector for another one tommorow. Hopefully this works.
I've found out/realised that the bottom of the phone is less sensitive than the top, so compare the top and bottom half of the screen.
The top of the screen is *almost* as sensitive as every previous smartphone I've owned or used (mainly Samsungs, HTCs and various iPhones). I can just touch the screen without it registering, but only just.
The bottom of the screen is a lot less sensitive. When selecting (tapping) things, it prob wouldn't be much of an issue, but when I Swype using the 'keyboard', I get dropped letters.
A screen protector reduces sensitivity further (a glass one more than a flexible plastic one, from my experience)

I changed my screen protector for one from gearbest. Now it's working like a charm!

I9300 Touch not responding until I press screen hard?

Hi guys. I have an old I9300 and it works great for it's age. But, when it gets a little hot it stops responding to my touches. I found out that the only solution is to press it hard in the lower left corner and then it works normal after that until it happens again. This solution works all the time. I tried opening the phone up and pressing that part (there's a connector for something there) with a small piece of paper, but it doesn't help.
Anyone had any problem like this or something?
Thanks
PS: is there any remedy for the horrible screen burn in except a new display?
Lick your finger and touch the screen. if it doesn't work then the digitiser may be delaminated or faulty.

This sounds interesting enough Will try the next time it happens. Will also feel stupid doing it, but yolo.
Conductive screens work on moisture on your skin causing an x-y voltage drop..
Capacitive screens work on x-y voltage resistance caused by pressure..
If it's glass is conductive. If it's plastic is capacitive.
Wetting your finger makes sure you don't have dry or dirty hands and ensures a good contact. If you were licking the screen itself you might get a funny look from passers by..
