Is anyone else having an issue with phantom taps on the screen. I know sometimes my screen will pull up the keyboard and start typing. Or if I am scrolling a web page it will think i'm zooming. Or if I go to click and hold a link in dolphin it will just click.
yeah while browsing i had the same problem, maybe some bug that will be crushed after an update.we have to bare with this in the meanwhile.
I'm reading on other forums like the Nook that a screen protector may help fix this.
Plugged in?
Does this only happen when the flyer is plugged in? I had this problem when I was trying to use the flyer while it was plugged in and it just started doing as it pleased. The first couple of times it freaked me out! It just started typing crazy stuff and started navigating from screen to screen as it saw fit every time I went to touch the screen. I thought it was demon possessed (some kind of ouija tablet), but I didn't call a priest I just unplugged it and all was well with it's formerly possessed soul.
.
I have a problem when It's plugged into the power. Scrolling pages sometimes zooms and buttons can activate if my finger is just close to them.
In some countries like here in the UAE, the combination of badly earthed mains, leather-soled shoes or bare feet on tiled floors and a very sensitive capacitive screen causes strange tap response.
Ever held a charging phone or laptop and felt a slight electric buzz??
I usually find if I clean my screen and remove any finger grease, it tends to work fine after that.
Also, even if not on power, I have found a problem with tap and hold (say to trash icons) that if you press the screen too hard, the hold does not 'hold' ... If you use a light tap it works fine.
Large finger surface area on hard press seems to confuse it.
It happens when it's not plugged in.
My screen was so sensitive it would open apps, etc. even when my finger was 1/2" away from the screen. It was frustrating. Cutting down one of the matte, anti-glare screen protectors I had left after I returned my Galaxy tab solved the problem.
I bought some screen protectors of Amazon... Thanks for the input... its the only downside to this thing :-D
Ok, so aside from a few barely noticeable dead pixels, my TF Prime is fine.
But 3-4 times I've had this weird issue... the TF will all of a sudden start freaking out, flipping screens back and forth, tapping on app icons, keyboard keys, etc. It's as if a ghost has taken over my Prime, lol... what the??
Just happens at random, doesn't seem to be a particular app or action that's setting it off. Has happened while using the stock browser, Evernote, and typing an email.
Anyone else seeing this? Some kind of software glitch, or do you think I got a dodgy touchscreen?
By any chance, do you have the keyboard dock attached? On a few occasions, I've had the palm of my hand kind of resting on the mouse pad and that will set it off - not a tablet flaw, it's just my hand in the wrong place. Without the dock, I've managed to accomplish the same "flaw" by resting my thumb too close to the screen. With a sensitive capacitive screen, you just need to be really close to the screen to set it off. If not, then you have a real problem.
Bye.
No, I'm not lucky enough to own the dock yet, got one on pre-order, lol.
It's not just one tap or two, I mean the thing just flips out, scrolling home screens back and forth, typing automatically on the keyboard, etc., like it's possessed or something... on auto-pilot. It will go on indefinitely, and the screen will become unresponsive to my own taps. The only way to stop it is by doing a hard reboot by holding down the power button for about 10 seconds.
Now that I think about it, probably a touchscreen hardware issue... seems like it's "holding" the tap on, not releasing the tap off when it happens. I guess I'm gonna return it next week, ugh.
I qwas having this problem also but it started happening after i put on a skinomi screen protector. People thought i got water in tablet but maybee that wasnt the problem. If your having same problem.

I've had that happen many times on my Nook Color. Drives me nuts. Certain games trigger it for me. Or sometimes it seems to be caused by my hand touching the screen or more than 2 points ( which is all my NC can handle )
Found that if I turn the device to sleep mode and wipe screen good, it usually fixes the issue. Either that or sometimes I have to reboot and it is normal again.
Glad I'm not the only one with a possessed tablet.
Due to damage done to the LCD of my S II I had to replace it. So I did that and I noticed two very serious issues. The first being the unresponsive touch buttons to the bottom right and left of the device. They were also not illuminated, there was also no evidence to suggest they were not connected correctly.
The second issues and by far the biggest is the unresponsiveness of the touch screen. When I enter my pin the first touch takes a few seconds to respond, then it proceeds to work as normal until the phone is unlocked. From that point whenever I try doing anything it behaves erratically. For example when I dial out it is painfully slow to respond to the inputs given to the touch screen.
Is there are way to address these issues and remedy them if so how could this be done.
Looks like a bad piece of hardware. Did you get the spare part from a trustworthy store? About the softkeys, you could check if the connector is connected correctly. As a workaround, you could use onscreen buttons.
Did anyone faced issue - on wireless charger, screen touch response is bad or weird to operate. Note: it happens only if i enabled high touch sensitivity option.
YES!!!
I haven't tried shutting off the screen sensitivity though. I just got a wireless car charger/cradle, so now I have a reason to be using my phone while it is wirelessly charging. To me it seems to be related to the section of the screen. The top half of the screen seems to miss occasional touches, but that even happens when it's not charging sometimes. Bottom half of the screen is OMG awful. Missed touches, extra touches, touches randomly off in some weird direction, long presses when I didn't long press, moving/dragging when I didn't move. Try typing on the keyboard if you want a fun time. It took me *SEVEN* attempts to type "Here". It kept grabbing the wrong keys, hitting the spacebar in the middle of the word, just bizarre random stuff. I couldn't even recognize what was being typed...
that's not a bug my friend - that's an issue normally associated with a cheap wireless chargers or non-OEM wireless charger.
Tried this on my 9+ with a Ravpower fast charger and have no issues with touch screen sensitivity or typing on the keyboard.
Yes! Holy ****!t, thought I was just imagining things. I experience it with my OEM 2018 Convertible wireless fast charger.

Yeah, happens with me when I use a cheap wireless charger.
I use an iottie fast wireless charging cradle in my car and often the touch screen is finicky. I haven't tried turning off touch sensitivity.

Do you know what scientific or engineering principles are causing this to happen? Is the electromagnetic field generated by the induction coils somehow interfering with the screen's capacitive interaction? I have only used my finger. I should try a stylus to see if there is a difference.

I have a developer option turned on to draw a small dot to indicate where you touched the screen. Yesterday I was watching as I repeatedly touched the screen in the same spot. I did not move my finger from that spot. Just lifted and tapped over and over. The dot drawn moved around quite a bit. Mostly high or low, by about 1/2". The phone was somehow getting false readings about where I was touching. No wonder I had such issues with the keyboard. I have noted that pressing harder with my normal use, *does* improve its ability to sense the touch accurately. I was not really testing that with the repeated touches though.

you have to ask yourself two things;
1. is screen touch response happening while it was on wireless charger?
2. or is screen touch response happening while using your phone regularly even without not on charger?
if your answer is #2 or both #1 and #2, you should contact where you bought and exchange it. However, if your issue is #1 only, I would try to use different wireless charger to test and see.
Also keep in mind that Exyons version fo S9/S9+ has plagued with touch screen issues (i do believe this is also officially confirmed by Samsung);

I have Snapdragon.
Initial testing on another charger seems better (not perfect). I am going to play with placement to see if that makes a difference.
same problem here. running on stock fw with stock wireless charger... tried several version of samsung wireless chargers and all results the same
I have same issue https://forum.xda-developers.com/ga...rger-screen-sensitivity-t3779923/post76283002
Better to avoid wireless charger. So that screen can b saved in long run.

For my car, I just leave the phone in the wireless charging cradle, since I don't use the phone while driving, then if I need more than incidental contact with the screen while it's in the cradle, I just unplug the power source and the touch screen goes back to normal behavior. Annoying, but not unworkable.
I prefer the wireless charging because of past phone experiences where the charging port got damaged from needing to plug/unplug the phone so often. Unplugging the power source for the cradle is easy and not so likely to damage anything.
I had a fun one today I took my phone *off* the wireless charger and the touch screen went crazy. The dot showing where I was touching at the moment, was flickering down by the home button like it was the fire button on a video game. However, I wasn't touching the screen at all. So I shut the screen off (because no matter where I touched it just ignored me and kept mashing the home button). Then tried to turn it back on and nothing would happen. Normally when I get stuck like this I put it on the charger and it forces the screen on. I did that and the screen came on but it still wouldn't take my touch. So I finally had to reboot.
Did anybody was able to put the finger on the problem about touch issue with wireless charging?
(Finger on the problem...... did you get it..ok ok, need more beer)..
Again, we are taking about problem #1-: screen touch response problem happening only while it is on wireless charger!)
How does a "cheap" or none OEM wireless charger would affect the Touchscreen?
Mag field too strong? Android software disable touch while wrls/charging?
Can we lower some parameters on the phone trying to alleviate the issue?
I normally pick up my phone from the charger to use it, but out of curiosity, I just tried it on the charger, and have no problems. The charger is a Pleson Fast Charge model C500.
Try with high touch sensitive enabled. You might get issue.
Just got a new Tab S7+, and I found that I was getting a heck of lot of repeating keys from the Samsung keyboard and the Gboard keyboard. Hadn't noticed any problems elsewhere.
I finally got fed up with it and get Touch Screen Test, and I can see clearly there that the screen is registering a touch with my finger maybe 0.5mm away from it. That fits with what I see on the keyboard, where I can get keys to fire with tiny finger movements just away from the screen.
I can't find any settings in Android 10 to adjust this. It's surprising for a table that's been out of the box a couple of weeks, and possibly it's worsening.
I had an idea after I'd posted this - I often use the tablet connected to the 25W charger that came with it. If I use it on battery, the problem is much diminished , and possibly gone. Electrical interference, then???
Is it a return-as-faulty, would you say? Any test options I can use to help with this?
Thanks
Alan

Many thanks for that. My tablet has T970XXU1AT12 / T9700XM1AT12, no update showing as of a moment ago. I expect it will reach the UK soon and I will be able type!!
I think the touchscreen of this tablet does have some interesting behaviors, as I've also observed some touches being registered when my finger was a still a short distance away. I suspect this might have something to do with palm-related gestures (like palm swipe from right to left for screenshooting).
I play rhythm games on this tablet mostly, and I'm seeing some cases of taps not being registered properly (unexpected misses), which happened less often, when I was playing those same games on my phone (before migrating them to the tablet).
I don't constantly put the tablet on the charger, as I've lessons learned from my previous tablet, Pixel C, whose battery went swollen after having placed it constantly on the charger for quite a long while that I ended up replacing the swollen battery with a new one by myself. While it was a lot of effort in overall, but the swollen battery had made the glues between the screen and the chassis mostly visible, that removing the screen became much easier.
I couldn't confirm this issue.
I've installed a safety glas on top of the screen. Fingerprint and S Pen is working but I've no issue's with a to sensitive Display
Update came yesterday. Still not fixed
I'm also using a tempered glass screen protector and my personal experience with such protectors on different devices has always been positive, with few issues directly related to such protectors as long as the quality appears to be good enough. I don't connect the charger while gaming, but I do attach a Type-c audio cable for connecting the tablet to desktop speakers.
On the other hand, some lower quality charging cables would certainly cause issues with touchscreens regardless of device. Usually with stock chargers and cables (or those from very reputable vendors) you can mostly rule out this possibility.
EDIT 6: Moved the rest of the issues I'm having to a separate thread.
