I have noticed some strange behaviour when I connect/disconnect the power lead from the magnetic connector and was wondering whether this was a "local" issue or whether it was "just me"
1) when the lead is connected/disconnected, there is a "jump" in the screen which sometimes re-loads the view. This can have the effect of wiping anything that may be in progress
2)Screen responsiveness becomes almost non-existent meaning that the power has to be removed before being able to use the tablet.
Just wondering..........................................

After upgrade to XXKG2 firmware 2 days ago, the voice command launches randomly. Exactly like you press twice the home button. So, I been suspicious about home button or accidental push. But this occurs also on the table, without anything near to it. But I got more worried about this, when this issue comes, sometimes the battery icon show up the charging icon
Also detected randomly "wake ups", with the screen dimmed... without any touch
Yes, I could freeze or remove the car dock app or the voice command app, but this will not fix the source.
Anyone having similar issue or figure out some fix?
EDITED: Problem fixed ... my results here, in other thread:

Hi everyone. After changing the usb pin of my phone, the touch screen started doing some weirds things. Sliding among desktops is rather laggy. Pressing an icon is not enough to get the app (or whatever) to work, a second attemp is neccesary in any other part of the screen in order to make it happen. The physical buttons seems to be working fine so far.
In further investigations it seems like pressing on the screen is well detected, since i can press an icon and move it around a desktop. But unpressing anything goes undetected.
I see no physical damage on the screen or the flex that connects it to the motherboard. This is not an issue related to any especific rom or kernel since i tried with a couple of them before getting to this point. Is there any app that allows me to monitor what part of the screen is being touch?
Can this be resolved by a firmware update of any kind of just a hardware replacement?
Cheers
A few threads have already been made, most are in various subforums of various phones. I think it's an Android problem, not the phones themselves.
Here's the deal:
On Android 4.x (I'm on a Nexus 5 with 4.4.4, CM11 M11) with the lockscreen set to swipe only, no security (but that does not matter, happens on PIN as well...) wake your phone out of standby with a quick tap to the power button as you'd usually do. Then, long press the power button for around 10 seconds, maybe a bit longer. The phone now reboots and throws you back to the SIM PIN prompt.
For me this happens when the phone is in my pants and I kneel down. The tightened fabric of my pants pushes and holds the power button down. If I'm lucky I happen to feel the short vibration after booting to know I will not have any cellular connectivity unless I get out the phone and enter the PIN. If I don't realize what just happened I'm unavailable for the rest of the day.
I already tried https://play.google.com/store/apps/details?id=com.nezdroid.lockscreenprotector, to no avail. This issue is independent of the power menu being present.
Do you guys have any idea on how to fix this behavior? Either by totally disabling the power button whilst in the lockscreen or specifically disabling this 10 second reboot thing?
On every Android-powered device I've ever owned (several dozen at this point), holding the Power/Sleep button for ~10 seconds or longer causes the device to shut off and reboot. It's not an Android issue (because older Windows Mobile devices like the HD2 running that OS did the same thing), it's simply how the devices are designed to work as I understand it, there has to be some kind of way to shut them down/restart them in case of some hardware or software issue that prevents the actual buttons - whether soft or hard - from working as they should. Not every device has a removable battery so, if it gets "stuck" and can't be shut off, it would stay on till the battery was totally dead, so this ~10 second thing was added in a long time ago.
This is basically the same as where pressing and holding a computer's power button for ~4 seconds or longer will shut it off - the difference is that Android devices tend to reboot immediately whereas a computer will actually stay off.
I don't think there's anything that can be done to stop this behavior since it's an aspect of the device's hardware. Maybe something is possible, but I can't say for sure as I'm not nearly as knowledgeable about the deeper aspects of today's smartphone hardware technology than some others, who knows.
From this point of view it totally makes sense that you can't disable this feature. Unless there's a rewritten kernel or something...
Do you think there might be a chance of an app disabling this feature or is it hardcoded into all devices?

All devices have this. It is a safety feature just in case it freezes and your devices doesn't have a removable battery. It would take a custom kernel to pull it off
Hi everyone, I've had my Moto Z for a couple of days now and am pretty happy with the device - even with the battery life I have one small problem, however.
Sometimes, when the screen is turned off, the Moto Display approach action won't work. In these cases, I also notice that the bottom right IR sensor isn't lit up - which it usually is when the display is turned off. The approach action only starts working again when I pick the phone up. This is very inconvenient and not how it's meant to be.
Is anyone else experiencing this bug?
At first I thought it might be an issue with Doze putting the process responsible for the Moto Actions to sleep, but after whitelisting all Moto apps the issue still sometimes occurs. I have not yet found out under which circumstances this happens.
Any help would be greatly appreciated!
EDIT: It seems this issue only occurs immediately after turning off the screen, after which there is a slight delay (a couple of seconds) before the IR sensor is activated. I will observe if this is really the case, which of course would render it a non-issue.
For a week or two now,* I have been having some funny things happen with my Redmi Note 4 (Qualcomm, Global) phone.
Before that it had gotten water in it and basically shut down entirely, but they fixed it and got it up and running. When I picked it up they showed me watermarks on the screen, saying that the screen had frozen only once but that it may just be lagging.
Since then I have had a few symptoms of an issues, perhaps hardware issues, but potentially something that I can fix without paying more for parts.
Here are the things that happen:
- Music stops suddenly (screen on or off) and the music app has to be reopened (DoubleTwist, Miuiu's Music app, etc); Somes while in Doubletwist, if I click to visit home screen (square button) than the music stops. (this is the first issue that I noticed).
- 1-2 seconds of white screen before already-open apps appear after selected; Sometimes problems with apps loading or screen goes black when loading
- When closing apps or returning to home screen, it looks like the desktop(?) background comes up and then a second after is is re-populated with icons as if system is refreshing the home screen
- Once any of these issues begins, it usually worsens and the cell phone gets slower, behaving more and more strangely until not even useful to me; Reboot clears it right up for an hour or two or whenever this wierd stuff starts to happen again
-It seems like if I make a point of using the phone modestly, slowly, I can avoid these issues from starting up
- Sometimes reboot rometimes hangs on initial black loading screen
- Sometimes if I hit the power button to turn off the display, I can not turn it back on with that button (neither does the battery-dead orange light flash), so I have to reboot.
-When I turn the phone screen off while it has been working fine, I come back later, turn on the screen to find that it is now on the boot logo screen and it stays until I hard-reset the phone.
So, these are potential issues I have guessed at:
* Screen damaged? So far, other than watermarking at the top and some backlight bleed, sensistivity is perfect on the phone, and symptoms involving screen always seem to be triggered more by apps or pressing buttons.
* Apps or Android corrupted/internal memory damaged? I backed up via Settings and did a Hard/Factory Reset, then restored from backup. I still have the problems.
* RAM partially damaged? I test RAM with two apps and none of them showed issues. Namely my available RAM and used RAM reported always add up to the 4GB my phone has.
*Other Hardware Components failing? I used 3 apps to check all of the hardware devices and sensors that I could think of. Vibration is the only thing that does not work, and honestly, I don't care much about vibration.
Today I have suspected that settings may being at fault, and/or battery savers turning off my audio. Battery savers often identify my music apps as using "excessive amounts of power," perhaps because the speakers at involved, but it does make me think... I removed any battery-related and security apps, then turned off all battery saver options in settings earlier today. In 2 hours of music listening after that, I have not had any shutdowns, but I am not convinced I have solved the problems. In the weeks after this, the issue is back and the audio issue is always followed by the phone operating very sluggishly.
I have done a factory reset and restore, and the issue persists. Do you think there's any point in trying to do a clean reflashing of MIUI? Could it be a software issue or definitely hardware?
What advice can you give me?
Thank you for reading.
You can try booting in safe mode and then check if the problems still persist. Other than that, I suggest you to get advice from senior members of the forum.

Miui 9 does not have safe mode to boot in.
