Whenever I'm charging, I feel the screen scrolling being "heavier" than normal, like having a slow response and being more sluggish. Sometimes gestures are registered as just taps and sometimes when I'm glide typing on a keyboard, the touch response stops, and shows as if I lifted my finger. Doesn't do it all the time and is not consistent. Used the S-Pen to draw all over the screen to check if there are any dead spots, but there aren't any. I'm on the Exynos model, and I'm using the original charger, and also a Samsung wireless charger which also displays the same behaviour. I also believe it does it during a call as well, but I'm not too sure. Have tried with and without a case, increased and decreased the screen sensitivity, removed and reinserted the s-pen, and it still does it. Any ideas or anyone having the same issue?
Well, no, my exynos10+ behaves the same, charging or not charging
From what you're explaining it sounds like something is spiking your cpu periodically.
Probably an app or a setting you've made eg. Sync/backup when charging
I have not seen this on the note 10, but this has been reported on and off as an issue since samsung started making android phones.
Best practice to never use this phone when charging.
It will completely skew the charging power curve resulting in slow charging and warmer running especially with fast charging.

I would like to have the screen power down, but leave the touchscreen active. Then I can tap/swipe the screen to return the display, instead of hitting the power button. [Note: This is only for a "docked" state.]
Also, since "Display" is always the battery killer, this could prove useful for battery savings. With the screen dimmed to 20, I'm drawing about ~500mA. With the display is off, the power draw is ~100mA. Pandora is playing away the whole time. [Note: I'm not checking the power draw often, so take these numbers with a grain of salt.]
I would really like the nitty gritty details on how the power is routed to all the components (i.e. what can be independently powered up/down, and what is on the same power bus).
Any kernel gurus out there?
To be honest, this just sounds like a not-so-good idea.
Why not just flash something that gives your optical button joystick thing an unlock function?
And if you are just using this for when it is docked, why not just leave the screen on?
So, flashing an unofficial rom is a good idea, but tweaking one is not? If people didn't try the "not-so-good" ideas, this site wouldn't exist.
I have CM7, so I have the feature... disabled. The OJ button pushes the phone "dock" across my desk, and unlocks my phone if I pull it out of my pocket the wrong way. Besides, this is only substituting one button for another.
At a minimum, it would be nice to get the backlight to <5 (out of 255, not %), but I assume a full power down is where the real power savings will come from. I just want to tap the screen to bring back the UI.

Charging + screen on + CPU active = overheating battery. (i.e. It's not good for the battery.)
No need to get defensive but I see your point.
I think he just meant not optimal or efficient but it is your phone and actually sounded like an idea I thought of a while back. I'll be watching the thread.

That was more after-work-commute mood than anything he said. I thought I caught the pissy bits (that isn't the original text), but apparently not.
So, sorry, SealDog. I didn't mean to be such an _____.
Anyways, here's another way to think about it, or just more info....
I just plugged in to AC, and the battery is at 23%. This means the charge current is at ~950mA.
With the screen off, it's putting ~800-850mA towards charging the battery (fast charge rate). With the screen on, it's only putting ~500mA towards charging (trickle charge rate), and burning up ~450mA.
Somewhere around 40-42 degrees C, the charge controller drops to ~500mA, because the battery is getting too hot. Yet, I'm still drawing ~450mA, leaving almost no current towards charging.
When it gets hotter (42-44 degrees C), the charger shuts off completely. Now, I'm just discharging the battery.
I have run into this too many times. 6+ hours on the charger, and the battery has only charged up 10-15%. Not cool. (In fact, the phone is freaking hot.)
BTW, I'm trying find every on/off setting I can (e.g. 1x/3G toggle). Mainly, I want to know what each unit's idle power is. I read about lots of battery saving things, but do they really help? Does 1x truly draw less idle current than 3G? Does shutting off wifi, gps, etc. actually save power when idle? Byrong did a nice backlight + CPU frequency examination. I'd just like to go further. I have an incomplete test built in Tasker (I have to fix the stinking task priorities, and remove all "sleeps").
My ultimate goal is to have a set of Tasker profiles that optimize power consumption for my purposes, without sacrificing functionality. For example, my mobile data choice is on or off, but off means C2DM can't reach the phone. I have plans for C2DM, so this isn't something I wish to sacrifice. But, if the screen is off and the network load is near zero, 1x is sufficient.

This is available on my S3 i9300 with Siyah kernel, but I don't use it for two reasons:
- Accidentally activating the screen and waking the phone
- The digitizer normally turns off, and leaving it on drains your battery.
Hi all,
From the first day i have my device, while it is connected to charger, although i just use my one finger it feels like multitouch, so it zoom in or out screen. After disconnected charger, i firstly lock then unlock screen and after that i can use my device normally. It sometimes cause screen vibration with no multitouch supported softwares. But it actually can't let me use any browser while charging...
I though it was because of setcpu profile but it only has 1.2 ghz and i already have this clock speed between some battery levels. What problem should be with my device?

I think that the htc devices have a earth(? is it called this way in english? The negative pole of a battery?) problem.
They are the only devices who have a metallic battery cover which is connectet to the device itself. (Lock for the small pins)
I also have your effect sometimes, but when i touch with one hand the battery cover it's a bit better.
on my old hd2 it was the same, but even more worse...
Seems like a generell htc failure...
It is fairly common for devices to have problems with their touchscreens while charging. Not just HTC; I have the same problem with my Nook Color, and I had the same problem with my Motorola Cliq.
The most common theory I have heard is because the charger does not charge at a consistent rate, which messes up the capacitance that our touchscreens use. This is especially true with aftermarket chargers, but can sometimes even happen with the original ones.
The best thing to do is to try not to use your phone while charging, or spend the extra money and get only original (OEM) chargers.

you mean "ground"
ps: in my language also we use the same word for earth and ground

You have it right. I think the full word you're thinking of is: ground
Though I would think and hope all devices have one. Of course having a capacitive screen there are more complicated issues to deal with since you still need to maintain a certain amount of static charge on the screen. Basically your body is used as the ground on a capacitive screen. Obviously the ground on some phones is interfering with that.
I was aexperiencing a similar problem. Whenever i would use the Mugen battery and the second i closed the back cover, the phone would switch off. if i let it a little open it would play normally. With the standard battery although it didnt behave as such. Weeeeeeirrrrddddd

I already have an orijinal charger.
what a strange! i can't even think to see any user who have the same problem with me This really made me suprised.. So does anyone have any solution for this issue? The most common solution is not to use our devices while it is charging

That was my solution. I charge my phone while I sleep, so I don't have to worry about it. I also have a charger at work, so I can "top up" the battery during the day, if I need to.
i found out touching the metallic part of the phone sometime cured the problem
While charging, i opened multitouch app and confirmed red and blue colors change to yellow and green sometimes...

The touch feels really hard while charging and the scrolling responsiveness also suffers considerably.
Anyone else facing such problem? I also feel a strange vibrating sensation at the back of the phone while charging.
This problem continues even after unplugging the charger and only a reboot fixes it.
I always use stock charger shipped with the phone and I have tested it on multiple power boards at different locations in my city. Everywhere I am facing the same problem.

I think the Vibration while charging is quite normal for all Honor 8 Pro users, even me too have. But don't know about touch issue, because i never had such problems.

That vibration sometimes happens while charging if your body is in contact with earth somehow. I guess because of lack of earthing or such.
Regarding the touch issues, no issues here.

Yes! I have that issue... if i plug my phone with bundled charger and its kept on flat table surface, so without lifting my phone in my hand i can't use that easily. The touch response is very poor on that condition but when i lift my phone in my hand then its working normal, even i'm facing the same issue with connecting my phone with PC though.

sounds so different
My Moto G5S XT1792 had overheating problems since I bought it 9 months ago but I considered it a "feature" and that Motorola would not admit it was a problem. The phone would get severely hot when using GPS and 4G at the same time.
But then, overnight, the battery bulged and raised the screen out of its frame! Finally, the battery was replaced under warranty.
Since the replacement, the battery is lasting many hours more and the phone is barely getting warm even when charging under turbo charge. I am in love with my Moto G5S again.
The normal response of the fingerprint is to vibrate and then either lock or unlock.. Or, if the finger is not recognized, it vibrates and a message is displayed.
My setting is to use the fingerprint sensor as navigation button ("One Button Nav" under Moto Actions Settings).
But when my phone is being charged, the fingerprint sensor becomes erratic. If I try a sequence of lock and unlock fingerprint procedures, giving a few seconds after each retry, many times the sensor does not respond as expected. It becomes a trial and error: sometimes it works, sometimes not. Sometimes the navigation commands are recognized (swipe left and right, quick press).
It seems that this erratic behavior is not common because I could not find other users complaining about it. I wonder if my fingerprint sensor was damaged because of the overheating problems I had since I bought the phone or maybe during the battery replacement.
I would like you to try a sequence of lock/unlock fingerprint procedures while using the original AC charger in your phones and let me know if you experience the behavior I described above.
I want to get more feedback before I request a screen replacement under warranty.
Thanks!
This is not uncommon with charging phones, and is due to interference from your big, water containing body, and the AC power ground loop, on the capacitive finger print sensor. Some phones, houses, chargers and people are more or less susceptible.
Try charging from a DC source (battery bank) if you have one, and see if the problem goes away. There isn't much that you can do about it, and I probably wouldn't bother myself with it anyway, to be quite honest.
Anyone run into this yet. https://www.androidpolice.com/google-pixel-6-and-6-pro-screen-flicker/
"Some Redditors speculate that the flickering might be related to static discharge that's released when hitting the button."
Yeah, nothing like the rocket scientists at Reddit to come up with sound answers
Static electricity would destroy the display.
FET's are very sensitive to over voltage on their gates.
Maybe what they were trying to say was unintentional temporary surge on the gates of the matrix TFT's.
If that's the cause long as that surge doesn't exceed the max specs for the FET's in the matrix it's not damaging. If it does, outlook not so good.
If it's not happening during normal operation once on, it's probably a harmless quirk.
Who knows maybe intentional to give it some character I sort of think it looks cool... but Google isn't cool so yeah, it's a fk up.
I have it on my P6P. Turn phone completely off, quickly tap power button and it'll flicker. I'm guessing it's trying to power up but since you only quickly pressed the button, not full power is given.
I'm not worried about it.
I've seen no noticeable flicker at all. Perhaps I just lucked out on this phone?
By design there is an inbuilt delay so you have to press and hold the power button, this helps prevents accidental power ups and also allows time for the user to press other combination of buttons (i.e. to get the bootloader screen), so on a quick press things are still happening behind the scenes like a pre-flight check, and the screen electronics are probably immediately powered up as part of this pre-flight check.
When the button is released without reaching the timeout period to trigger a full power on, the phone just goes back to being off again, now you have a falling voltage which doesn't always drop immediately due to stored charges in capacitors, and that can cause odd glitches sometimes as components see lower voltages than they are designed to work with. With sensitive chips (like flash memory) there will be brownout detection, so they immediately stop cleanly when they see a low voltage, and before that voltage has dropped so low it starts causing oddities or malfunctions. The glitching might also just be the effect of other devices stopping and magnetic fields collapsing causing some spurious data to get to the screen before the screen itself has powered off.
It certainly isn't a fault or anything to worry about, just a quirk of the design.
is it really an issue? Or just phone geeks looking for something to complain about? What effect does it actually have on the usage of the phone?

Without knowing what's happening it's impossible to say it's harmless.
See my previous post.
At this price point I would send it back... or not and risk eating the repair latter. It could be mobo hardware related.
Google addressed this today saying to basically power your phone like you normally would, without pressing the power button in quick succession without powering the phone up, and that a fix will be out in the December patch/update.
It's not a hardware issue.

I had this happen once where the scrolling on the screen stuttered the entire time scrolling, then after closing the app and opening it again it was fine again, and haven't seen it since. My guess is that phone went into a deep sleep state, and took some time to wake
Ironically, I'm getting it using XDA website!
