Question Screen sensitivity too high? - Motorola Edge 20

I'm having a weird issue with a phone that I'm otherwise completely happy.
The screen feels too sensitive to the touch, which in turn makes pretty difficult to type quickly or results in many accidental presses.
Running the latest Lineage OS 20.0.
To reproduce:
Open keyboard, and hover your thumb over a key. SLOWLY move it closer to the screen where it's touching lightly. You should get ridiculous key spam, like a full row in 1 second.
Possible issue:
It appears that the 'finger' area required for a touch to be registered is too small
What I've tried:
Disabling haptics, different keyboard, changing "Cursor speed", a Magisk module that was supposed to add touchscreen sensitivity control.
Any pointers are very welcome, thank you!

I can recreate this as well. I don't really see how it could be a problem. I don't get accidental touches, in fact I find that the screen isn't sensitive enough and sometimes it doesn't register touches. The phone had a touch problem in Android 11 where it wouldn't register touches and I guess the devs tried everything they could to fix a display that was just too garbage to be saved anyway, so now we're stuck with how it is. I guess you could try a GSI with open source drivers that you could edit yourself since the drivers we have are closed source and the custom ROM devs (which should know better than anyone else) told me they couldn't fix it since they didn't have access to the drivers.

almost-real keypad on a touchscreen

I heard from a friend that someone is building a phone where the touchscreen keypad is almost as easy to feel as a physical hard-button keypad.
The virtual buttons (0-9, *, #) are spread out in a typical rectangular grid over the whole screen, with large gaps between them. When you (lightly) move your finger across the screen, it vibrates as your finger is passing over any button. If you want to actually press the button, you have to push your finger against the screen harder (this event is acknowledged with a beep).
This sounds like a great interface. Has anyone seen/heard of it? It also seems relatively easy to implement on any PocketPC, unless there are some problems that I'm not aware of.
I'm using one application that uses vibration as a feedback -- Phone_Pad_Vibrate.cab. However, it vibrates only when you actually press a button. I think it's a great app, but obviously its purpose is very different from what I'm talking about (e.g., it won't help you find the right button if you just shift your finger around the screen). Also, I found that it's not reliable -- if I use fast, light touches, I can dial a whole number without any vibration. It may be due to the lag between the button press and the vibration, or due to the different pressure threshold used by this program and the actual phone dialer. If it's the lag, I wonder if it's a technical limitation of the Kaiser.
The screen on the Kaiser (and most other PocketPCs) isn't pressure sensitive, that is, it can tell when you are pressing, but not how hard. You would need a special screen to achieve that.
You are talking about screen technology more advanced than most PocketPCs are currently equipped with. the iPhone has what is generally regarded as the most advanced touch screen in a mass produced product. The software would need to implement it, but the screen's hardware would need to be able to do it in the first place.

Touch screen bug in pictures

I've been effected by this problem for a while now, it's an issue on stock and cyanogen's rom. So far as I can tell a phantom input is detected at a very specific location on the touch screen provided the primary input is within a specific range along the vertical axis.
I've taken screenshots with the Pointer Location Tool in Dev Tools and wrote a short description of what's going on in each screenshot. This seems to go show up and go away sporadically, seemingly for no reason.
Screenshots here:
http://dl.dropbox.com/u/1620808/touchscreen_bug.zip
If I rotate the screen once and back, the single input part of the bug goes away, if I use two fingers though as shown in one of the screenshots, the bug is still there. Then after letting the screen sleep for a minute or two, it's completely gone.
Anyone else with this problem?
This is a known problem, there are two many threads already stating this
The phone is not yet fully supporting multitouch 100% it only has pinch and zoom, CM has said he found something in the framework that is disabled and should fix this when enabled (but not completly fix all multi touch issues)
I'm not entirely sure how much of this problem is a multitouch issue. I've noticed in particular that when I touch a specific area of the screen, it registers in that place and in a second place that always has a fixed point along the y axis.
This often makes scrolling a pain as I am only able to flick up in the area above the affected location.
This problem can also make typing a pain when I type on the second from bottom row and instead end up hitting the bottom row.

[Q] Screen sensitivity

I am not sure whether it is my mind playing trick with me or not, but I feel like my phone is less sensitive after I did the hard reset (power+volume down). Sometimes I need to press 2-3 times because the first light tap was not detected.
So is there anyway to increase the sensitivity?
I have the same problem, but no idea that is the hardware or only software problem.....
Fresh owner of this Optimus 2X in France, in our community, frandroid.com, we encounter the same problem , I think this is a software issue.
Did someone already contact LG??
Maybe they should include this into the bug list thread.
May I know were you guys having this problem since it is out of the box? or after reset?
I have the same problem started from day 1 till now
I have the same issue and already thought I'd be the only one having this problem.
I would not say it's a problem with sensitivity, but it feels like the touchscreen goes into some kind of sleepmode where then you need to press a second time, to wake it up.
Continuous touching is no problem. (like when typing rapidly on the keyboard)
This video is not from me, but it shows the problem.
Have a look at 13:28 and 13:37. The reviewer tries to hit the "Ackermann" entry, but the touchscreen does not recognize the touch. At 13:37 the guy has to press another time to get the entry selected.

Yes! The touchscreen is definitely less sensitive than my old HTC Hero, and gets quite frustrating sometimes when a scroll misses the first part of the movement or a click is missed.
Sent from my LG-P990 using XDA App
just in case, are you guys using 20110218 baseband too?
The same problem here. If I unlock the screen and then tap on any on screen apps, I need to touch again for it to open. Only the first time though, after that it function ok. I think this is a bug and needs to be fixed... I have my pc for double-click.
Yep, count me in. Same problem here. Sometimes screen taps aren't registered. Will do some research later on, but I think it's a software problem. (maybe you have to tap 2x as fast )
Hi,
same problem here!
Potentially a driver issue. A Nexus S user had a similar issue in this thread: http://forum.cyanogenmod.com/topic/18431-tuning-driver-to-deal-with-unresponsive-touchscreen/
He managed to tweak the driver and it works fine now. Need to know C++ (I think?) to understand though.

I see, then probably they will fix it on the next update/gingerbread?
Same issue here.
Correct me if I'm wrong, but the problem seems to be that the screen has zero tolerance when it comes to tapping and swiping together. If you tap and slide your finger a bit directly after the tap, the tap is ignored. In other words your tap has to be a steady tap when you click on a button or an app. Right on the spot and with no swiping or sliding afterwards. I can't reproduce this on any of my other devices.
Ergo, it seems that the natural tapping I'm used to isn't working on the x2. It seems like I have to adjust my tap. I think that this could in principle be solved with a setting somewhere, because clearly the x2 is capable of registering this in for example a web page.
The great thing of this is that you can safely tap and swipe in the app drawer to scroll up and down or left and right. The downside is that a tap with a little swipe isn't registered at all. I would say that LG has choosen here for a wrong setting.
My personal experience about screen sensivity.. can you confirm if it's the same for your device?
I noticed a strange touch response.. and after some tests, I can say that the touch screen and icons are influenced by the surface where the phone was put!
with the phone in my hands, it's all ok (only sometimes - rare - I need to tap more than once).
If I put the phone over a glass surface (like a glass table) without touching it with both hands, the touch and the icons not respond!! NEVER!
If I put the phone on my scanner the touch screen works ok, but the icons not (or only few and rare taps was detected).!
If I put the phone over my big Onkyo amplifier.. It works like in my hands.. or better!! even without touching with hands.. only with a finger!
Put it back on my glass table.. and all stop working again. If I put a aluminium foil under the phone (between phone and table).. the touch and the icons works again !!
If I put it on the bed.. it don't work.
LG support say that they have tested the phone about this issue after my report.. but no strange response was detected by them. I don't know if they really tested it..
Try it and let me know what you think about!
tested on glass surface, I can press and swipe through pages with a finger without problem.
it is true that my device is not so responsive, but aint reaching that level yet
i read about a similar behaviour on other devices because some devices need a proper grounding for the capacitive screen to work correctly. You can find this problem via google.
Some devices have problem in a car-mounting, for example.
But i think thats not the problem the thread-opener talked about?
Guys I'm looking to get this phone and after reading Engadgets review of the X2 where they mention that the screen is not as sensitive to the touch as other phones I got a bit worried and started googling which lead me here!
Is this true? The screen isn't very sensitive and you have to apply more pressure than other capacitive phones?
I know that the OP is talking about a different issue but I reckon LG will get that sorted out via software update, or at least hope so!
Please do post your experience about the screen sensitivity of the X2 as this is putting me off. I currently have the Motorola Milestone 2 which is very sensitive to the touch even with a screen protector on it.
Cheers

Touch Screen Sensitivity...

Anyone else having problems with the sensitivity on fast scrolling? Seems to not be as smooth or compared to the iPhone 6 and HTC One M8 I have been playing with...It's almost too sensitive or something, I can't quite put my finger on it.
Do you mean the effect where things sometimes bounce back while scrolling?

There is an earlier topic about it here: http://forum.xda-developers.com/z3-compact/help/swipe-issues-t2888154
The phone has an extra-sensitive touch screen because it has a "glove mode", and I'm thinking the effect of the technology for that glove mode isn't completely suppressed when the glove mode is disabled, so the touch screen would still be slightly more sensitive than those of other phones, even when glove mode is disabled.
If glove mode is enabled, the touch screen is so incredibly sensitive that without gloves, it will register a touch when you hover your finger about a millimetre above the touch screen.
I found that for me it helps to use "lighter" and shorter swipes. Also after a swipe lifting my finger a bit higher off the screen than I was used to.
Some people might always have been doing shorter and lighter swipes, hence not everyone is experiencing the problem. It's also been said on the Xperia support forum that not all units use the same glass for the front; some use "gorilla glass", others use "dragontrail" glass. That could also be influencing the touch screen sensitivity/behaviour.
I've adjusted my swiping habits relatively quickly and now I get the bounce back effect only once in a while.
I do hope that Sony comes with a firmware fix to compensate for the over-sensitivity though.

hi, is it normal? happen to my unit also.. quite annoying i can tell.. different with my TX..
Go into developer options and enable "Show touches", perhaps touch the screen a few times then turn off show touches.
Sorts it out for me! I was having a nightmare swiping down to select words in Fleksy.
This workaround will do for me until Sony fix it properly!

I really wish there was a way to turn down the sensitivity. During typing, I frequently have screen presses register as very short swipes, which is incredibly irritating, as I then have to backspace and delete two words.
Not really helping you, but this shows how sensitive the z3c display is:

Touch screens usually respond to metal. The screen of my Z2 tablet does.
My screen is so sensitive I can operate it using my leg... through the pocket. I saw in Z1 and Z2 threads that there is a config file that can be adjusted, however I'd have to root in order to do that, and I don't want to risk losing my warranty (esp. not when reading about glass breaking by itself).
It's not a massive problem -- all it takes is switching off "double tap to wake" and camera launch button. But those are features that are useful. On the other hand, having my phone suddenly switch Torch on, call a random person in my phonebook or reorder icons on the launcher desktop isn't all that exciting either -- not a fan of surprises.
Has anyone else found the Z3 Compact screen too sensitive? (Glove mode is off, obviously.)

On my previous phone (xperia acro s) it often happened that my leg messed with the phone when the screen went on for the alarm going off in my pocket. It was really annoying. I was always afraid that some important settings changed without knowing it.
My screen is so sensitive that I the last couple of weeks only have managed to send a few sms without having to delete several words that are written wrong...!
The speeddialer is also terrible and often leads to wrong contacts...
This phone is by far the worst phone I have ever had regarding these issues!
Is this a sign of a faulty phone or can you relate to these problems as well?
Is there a solution???
My speed dial wasn't working out of the box. Had to make a factory reset, that fixed it. Sensitivity isn't interfering with my writing though. My previous phone was a bit bigger so I had to get used to writing on a smaller keyboard. But why would touchscreen sensitivity be an issue when writing anyway? Are you using a swipe keyboard?
No I'm just using it out of the box settings...? I can see swipe is enabeled but I text normal... I have had to disable autocorrecting words when I write... It is really strange... I have had many different smartphones over the last 15 years and this is by far the most responsive ever tending to be useless because of the many mistakes I make during calls and sms...
I never had any issues what so ever with my M7...?
I have just disabled "motioninput" (roughly translated from danish...) under Xperia-texting and this seems to have helped alot!!!
I'm on the same boat - it's too sensitive compared to my m8. Hoping for update to fix it
You really should try to do what I did and disable motioninput! It really helps ??
I'm on the same boat - it's too sensitive compared to my nexus 4. Hoping for update to fix it
I go into running apps and force stop com.sonymobile.touchscreen.touchfilter.tfpss and it seems to be a little better, still sensitive but at least no bouceback. I should try pm blocking it.

I've tried this as well, but unfortunately no change, I still get bounce-backs when I don't use particularly light and short swipes.

Question Touchscreen problem

Hello to all owners of this device! Has anyone encountered the problem of poor touchscreen response at the edges of the screen? I know that manufacturers make the edges of screens - waterfalls are less sensitive, but something is wrong with my device and it's just awful ... The phone can respond perfectly to touching the edge of the screen for a while, but then, at one point, it stops responding to pressing. I press one point 4-5 times and the phone simply does not respond to my touches, then it seems to "wake up" and begin to respond normally to touches. This does not even happen at the very edge of the screen, but 3-4mm from the edges where the waterfall already ends ... This is very disturbing in everyday work, for example, when typing text. "Lags" of the touchscreen to the edges of the screen is the norm for this phone or did I get a defective phone?
Spoiler: Video
Your browser is not able to display this video.
I was lucky to catch this effect once in a video. If you look closely, you can see that the phone does not perceive touches, although they are quite accented. Here, everything else is not so deplorable, it happens that he does not recognize 5-10 touches in a row. This happens not only in the keyboard, but in it it is most critical ...
Have you tried adjusting "Side swipe sensitivity" option in settings?

I tried increasing and decreasing the sensitivity - it doesn't help. This option is responsible for increasing or decreasing the distance from the edge of the display, where the back gesture is triggered and does not really affect the response to tapping on the screen. Also tried disabling the gestures - still the same. I don't know if I can return the phone to the service center as defective. I would like to understand before that, is it a touchscreen defect or do I just need to learn how to type on the display type "waterfall".

Yes, of course, I flashed the phone through the recovery and made a complete reset of the system. With other keyboards the same, if they are the same in width. Only a narrower keyboard helps, for example, the Microsoft swift key can be adjusted in width, it works better with it, but this does not change the essence of the problem. The problem is not with the keyboard, but with the edge sensitivity. As I said above, it happens that everything works well and all touches are registered, it happens that the touchscreen does not respond to many taps ... I tried to hand over the phone to the vivo service center in my city, but it was not accepted, because the phone is for the Chinese market. I am trying to return the phone to the seller on aliexpress, I hope I succeed ...
