I've just conducted a series of tests (just tracing the movement using the dev tools->show traces) and I've noticed the screen is much less responsive when I'm charging the phone. I have no idea why this is happening. I'm using the charger on my tablet, and it doesn't have the same effect. The tablet is just as responsive as usual. The charger I'm using is the one which came w/ the phone.
Issues: you have to hold down for longer to register touches. This messes up w/ typing. Also it sometimes lets go of a touch before you remove your finger. Quite annoying. There's also quite a bit of general lag: the keyboard stays up for a second before going away, home screen takes a bit to load up icons or widgets.
The second you remove the charger, it goes back to normal response. Quick screen response, no system lag, nothing negative.
Anyone experiencing the same issue?

Known issue with many devices. One of the custom kernels (might be siyah, can't recall just now) even has custom touch sensitivity settings for when the device Is plugged in.

Another cause of lagg when charging is choosing a battery icon that has a charging animation in the status bar. I have a S3 and it becomes very laggy with the charging animation so I chose a simple battery icon that doesn't have any charging animation and now it is the same speed when charging or not charging.

Am I the only one experiencing an overly sensitive Sense UI? Perhaps I'm missing a setting. I have looked all through /etc and can't find any way to adjust the sensitivity.
Anyone have a solution?
Touchscreen Spaz-out
I will say: occasionally my touch screen will just go bat-**** crazy, registering even the slightest movements as "clicks". The phone is completely unusable; god help you should you be in the lock screen.
Now, after observing this for a couple of days I have a hare-brained theory: it's related to how hot the device is. I've noticed that it happens after extended periods of use, or when it's plugged into the wall charger. Just unplugging it grants a short reprieve, and a refractory "cool down" period generally fixes it. Also it'll work sorta if you press down on the screen like you're trying to kill your phone.
Can anyone else confirm this?
I was getting a lot of the jitteryness and screen lockups before I loaded MR2, everything seems pretty fine now. I had more problems with my wife's myTouch than the eris for once last week.
I do not have any issues like this (I do have all the updates though)
-Chr1831
Searched Q&A and havent seen any other complaints to match my own.
My sgh-i777 takes about 2 seconds to wake from sleep when I hit the power button. This is only when on battery power. Maybe not a full 2 secs, but noticeable lag anyway (the only noticeable lag btw). It wakes up immediately when plugged in to AC power. I noticed the issue both on stock and CM7(which is freaking awesome) .
So here is my Q:
Is this normal wake behavior for the SGS2? Just got it today and wondering if maybe it is a hardware issue.
PS: I know I need to update my sig now... Dell Streak 5 was an awesome form factor, but holy **** I love this new processor! (But thumbs cramping a bit from the small screen, LOL)
I seem to have a lag too. I had it before root while on stock and i still have it on cm7

Fundamentally takes at least 650msec to wake up from deep suspend - add to that other wakeup processing and you get about a second.
Nothing you can really do about it - most of it is spent waiting for the modem to wake up.
The lag is getting me greif from iphail owners.... They're like my [stupid retarded lame piece of ****] Iphone doesn't lag.

Latest CM7 nightly (10) has LED notifications which uses wake_lock to prevent deep suspend. -guess I need to get a 2nd battery
Going to try it out. A bit disappointing that the most advanced phone on the market has this noticeable lag when waking. I have never experienced this on any other phone... I tend to accidently double hit the power button just to have it wake a moment later followed immediately by the electron beam CRT power off animation!
What really grinds my gears is that this wake lag NEVER happens when plugged in to the charger.

That's because charging holds a permanent wakelock.
Hi all,
Since Android Wear 2.0 the dock mode while charging with clock doesn't work any longer. When placing Moto on the dock it shows a black screen. When touching the screen de clock appears for a moment and vanishes after about 1.5 seconds. It appears to be a bug. Do you all have this bug or is it just me. Did anyone tried a reset of the watch? I would really like to able to fix it , cause I use that feature a lot.
Same here.
A temporary solution I have found is to enable in developer options 'stay awake while charging' now it stays on. But it is not the same. The display appears to be much brighter. probably because ambient mode (Not sure that's how its called) is not enabled.
Edit: That appears to be the fix. When turning on in settings 'always on display' it works like before. no need to enable stay awake while charging in developers settings.
Although this fixes the issue, I am somewhat disappointed because this option reduces battery life.
I noticed I should have put this question into 'troubleshoot and questions'. I am sorry for placing it here. Perhaps a moderator can place it in the right section for me?
Not a problem here.
Always on is normally activated.

I've noticed the same behavior when I upgraded my Moto 360 to AW 2.0
For me, the clock stays on but the background is really bright whereas it used to be black before
Same thing here, background to bright. I don't think this is on purpose. They would probably get out fixed in an upcoming patch(?)
Same here.
I liked docking my watch on my bathroom counter and using it as my clock while getting ready in morning. Now it doesn't stay on and when I tap the screen I can see it for a few seconds. When it is on ....the brightness of the background is terrible.
I sure hope they fix this problem.
I have the same problem
Can't believe there is still no fix for this?
This is really annoying! I was hoping XDA had found an answer. Having always on screen on is not a solution since Moto made a bad design decision on the screen making it best to turn that option off. I assume everyone else's keep awake while charging option doesn't really solve it either because the screen turns off once the battery is full. Anyone think there's a workaround to be found in Tasker and maybe AutoInput (maybe turn always on screen on while charging, off otherwise, or even based on hours). I'm no tasker expert, so I'm not sure if that combo could work on android wear.

I have found this to be an issue when I use a charger that is not the Motorola plug that came with the watch. If you switch to the Motorola OEM charger you'll see a lag of about one to two seconds but the clock will always come on.

I am using Motorola's dock charger. I am positive that the issue lies with Android Wear 2.0 and not the charger. Before wear 2.0 it worked as it should.
I think it's random with AW2.
After flashing a new rom at my mobile, I had to forget and pair again the watch to the Android wear.
From now on, the clock stays on during charging.
This was not the case before that.

I have the very same issue (watch paired with a Nexus 4, 5.1.1). Anything I can try? Thanks!
Well, at least this is validation for me. It's been driving me insane, and I'm almost positive it's killing my battery life. I used to be able to stretch a full week on a single charge, but now it's more like a full day.
I'm sure this is what everyone else has been experiencing: there is now a setting called "Always on screen" in Android wear settings. The new behavior for this setting is a strict enforcement of this property; that is, to be either always on or auto off. This seems absurd because before Android wear 2 (not sure if the option existed or not), it seemed to work as we expected, to auto off in active wear but stay lit while docked. There should at the very least be another mode for when docked/standby vs active wear.
Something else that makes it seem buggy is that when the always on screen option is disabled, and the watch is docked and charging, the screen is still faintly lit although only a blank black and no clock. I do think this is a bug and not a feature. For anyone interested, there are also settings for other things you might not be using. I'm turning them off and pray the battery gets better.

What r u talking about?
Always On was there since Android Wear 1.5.
And come again?
1 week use of the watch with 1 charge?
How did u manage to do that?
By turning on the watch for 2 hours every day?

When I charging my S9+ on a original wireless charger, the sensitivity is slightly disturbed. If barely touch the screen, it does not always work. Need to press a little harder.
With disconnected charger, and on a wired charger-all ok. Even light touches work fine.
PS. The screen film protector is pasted. But I do not think that it somehow influences.
Then you try to press harder and it takes it as a long press? Yup.
Try putting on the wireless charger and sending a message. The keyboard is completely useless. You just get random letters half the time.

Yes, I just installed a wireless charging cradle in my vehicle. I tried to use it after parking at my destination with it still in the cradle. It went poorly. I finally had to pull it out to do anything beyond the basics.

S9 or S9+?
Ps. Samsung Support responded that it sent information to the technical department.
S9+
Just tested my 9+ on a Ravpower wireless charger. No issues with touch sensitivity or the keyboard at all.
Since the OP has a screen protector, have you increased the touch sensitivity (Settings / Advanced features / Touch sensitivity)?

I'm also having the same issue with touch screen when using my car wireless charger.
I also have a screen protector and have the sensitivity turned up. Another post on the same topic suggested there was less difficulties if the screen sensitivity was turned off.
Continuing to use the wireless cradle, I can say that the issues seem to vary. A number of times it worked without any major issues. Yet a few times there were some very major issues. I have not been able to identify any commonality though. If the issues are bad, I just unplug the power source.
Slight refinement.
I have problem if barely touch the screen (when phone on wireless charger). If I press as usual- touch work fine.
Without wireless charger even barely screen touches works without problems.
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.
---------- Post added at 03:54 PM ---------- Previous post was at 03:48 PM ----------
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);

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.
