Hello guys,
I have a XT1641 (Moto G4 Plus) and I've just discovered that the ghost touch has a direct relationship to the screen brightness. I don't know if this has been discussed before but if you leave the brightness setting below 50% you'll likely won't have any ghost touch, not even while charging and no matter which charger you are using (turbo or not). But if you set brightness to 100%, at least on my phone, it goes crazy as soon as I unlock the phone, no matter it was inside a pocket or over the desk.
Looks like it's related to some kind of interference by the current needed to power the screen backlight.

Yep, that's already known workaround, for example here's a thread https://forum.xda-developers.com/moto-g4-plus/help/ghost-tap-fix-t3680814

Display Brightness problem with my Galaxy S
Hi I have bit of a problem with my galaxy S' display. The display uses a ton of power (90% +, going down 1% every 2-3 minutes with display on) as per the OS usage data. I have not experienced brightness settings / power saving mode as having any effect in terms of extending my battery life.
Now here's why I think there might be something wrong with my phone. I know two other people that also have a Galaxy S. We come together often last time I noticed their displays are MUCH MUCH brighter. I took all three phones on the table and noticed that regardless of the brightness level I set on all three phones, whether it be the minimum brightness setting or full brightness (all 3 phones SAME settings of course) mine is always the darkest. Also their phones display 40-60 % from the total power used by their display's rather than mine always showing 90%+.
I tried a battery recalibration etc this doesn't do anything in my view. After trying some great suggestion on this forum, I alway set the display to its lowest brightness setting, still no difference.
One of those other phones is running the same S/W as mine (doc's rom JPA) the other is still on JM2, so I can definitely exclude the firmware version as a cause.
Any thoughts suggestions as to how to solve this? Or might I just as well stop bother with that and have Samsung exchange the phone's display?
I have the same problem.. Did you find a solution?

Hi, No unfortunately I didn't. It is kinda strange I'm not getting any response on this thread. If you and I are having the same issue, I find it hard to believe we'd be the only ones!
There is a "smart management" option under settings (saves battery). This seems to change contrast etc when enabled and makes screen dimmer. I have to SGSs and I can confirm that, Check it and tell me whether it worked.
nb: this option will make a full white screen dimmer than if you have half white and half black (the white will be brighter in the second case - probably to improve contrast).
Hmm.. this is what I did.. I placed the brightness slider to the left and switched on the automatic brightness control. Now battery use does not show 50% or more in average use, but seems normal, like it was before froyo
Smart Management is off
Hi,
The screen on my Nexus 4 has started to stay awake. I've noticed my battery drain a lot quicker over the last couple of days and I also noticed that every time I pulled my phone out the screen was lit so I've taken it out and watched it. It just stays awake all the time. If I turn the screen off the minute a message or anything comes in the screen wakes and stays awake so near impossible to keep it off for any length of time.
I do have the developer screen enabled and had stay awake whilst charging option enabled. I disabled that to make sure that this wasn't causing the screen to stay awake thinking it was somehow on the charger when it wasn't however the problem persists even with that option unchecked.
I have the screen timeout in display set to 30 secs.
Anybody else experiencing this or no how to solve?
The phone is stock and unrooted though I plan on rooting later today.

Does it stay awake but go very dim? I have this issue too.
can it be caused by the screen protector blocking the light sensor somehow?
Can you install BBS (BetterBatteryStats) and see what's keeping your phone awake?
Sounds like a FULL_WAKE_LOCK is constantly being imposed on your phone.
Questions
Is it only when you put it for 30s?
What's around your pocket when you put your phone in it?
Do you have any attachments onto your phone? e.g. skin protectors, cases...etc
Does this occur on any screen or just your home screen and the developer options screen?
Though some questions may be obvious, the best method is to be thorough with the situation. Answering these questions will help us better help you.
My phone shut itself down about an hour ago (plenty of battery left as I had to charge it earlier and was at 50% when it did come back on). It took several minutes before it would respond to getting turned back on again. I've got 2 messages since and the screen is now tuning off as it should. I had turned the phone off a few times to see if it rectified yesterday however that didn't work.
The problems wasn't anything to do with me having it in my pocket as the problem still existed when I had it sitting on my desk. I have no screen protectors or case and I never put it in any pocket that has anything else in it as I don't want to ruin too quickly.
So not sure what's going. All seems very odd. Hopefully not a sign that the phone is on the way out but looks ok for now. Will have to watch and see what happens over the next few days.
Thanks to all who took the time to respond. Hopefully I won't need to bother you again on this issue but not convinced just yet
I got the orb recently and my plan was to use my phone as a bedside alarm clock with it. However, when I have the phone on "desk clock" mode while on the charger, the battery slowly drains overnight by around 1-2% every half hour instead of going up. When the screen is off, it seems to charge fine. Is the orb just really that slow at charging? It kind of defeats the purpose if it can't keep a steady charge with the screen on as I like be able to just glance at the time while in bed instead of having to turn on the screen first.
well the orb wont charge as fast as wall charger
but if it doesnt provide enough mA to charge while screen on i guess there is something wrong. however i dont have the orb, so cant help you any further.
It should still charge with the screen on. Mine will gain 1-2% every 10mins with the deskclock night clock on. Are you using a case?

No case at all. I am using the power adapter that came with it too, because i read using a different one caused problems too. I am however using visceralpsyche's gamma color settings from franco's thread which require you to have your brightness at 50%, but I should still be able to get a positive charge I would think.

i think you definitely still should. I know that if you place the phone on it centered near the bottom half (if you do it vertically, the phone will be about 1/2 - 3/4" from the table or whatever surface the orb is on), thats the optimal part of the phone to have touching it. If it's still not working, I'm guessing something isn't quite right with it.

I've tried a few positions all with the same results. I did notice though that with the first 20 minutes of charging, it will go up like 3-4% like it should, but afterwards it just goes on a slow and steady decline. I guess I'll contact Google about it, and I already had to sell my DT-910 because of the problems with that charger :/
Do you think the state of the "always on " really saving battery power than normal mode ?
There is some research that ?
I suppose you are asking: is the Samsung always-on mode better than a simple application that enables some kind of always-on screen ?
My answer is: no, the Samsung's always-on display is not a special power-saving mode. It is as bad as any application that shows a screen all the time.
GSMArena battery rating for S7 Edge without always-on display is 98h, and with the always-on display is 67h. So the always-on display eats a lot of battery.
On the other hand, the LG G2 has a rating of 60h without always-on display, and 50h with always-on display, so LG has a true efficient always-on mode, while Samsung is just like a simple application.

It's not saving power as it's still pixels that the battery has to power, especially since the clock and calendar has to move around the screen to prevent burn in on the AMOLED panels. While it doesn't use a lot of power, it still draws from the overall battery life of the device. If you're away from the charger for extended periods of time then i'd suggest not having always on display enabled but if you're able to plug in int the middle of the day if your battery gets low, then it shouldn't be a problem.
Yea. I thought I was going to like the AOD but I don't. For one I can definitely see an increase in battery usage and I also hate how it moves around the display. I know it's nessesary for image burn but while I'm at work, I keep my phone in a stand and every time the clock moves around the screen it makes me glance at it. Just got annoying after a while.

It eats 3% per 9hrs for me on exynos. Pretty good if you ask me
It's really a question of how much you use your phone as a clock. If you're constantly turning it on just to check the time and turning it right off, then yes, it can save power because turning the whole screen on just to check the time will use more power. Otherwise, if you wear a watch or have another source of time handy (or just don't bother tracking time that closely) and only check the clock occasionally on your phone, then you're probably better off with it off.
Of course personal preference is also a factor, but I'm just talking about the so called "battery saving" logic behind it. It'd have more potential for saving battery if it showed you your notifications like the Moto AOD does.

you meant LG G5; and yes, they seem to have developed their AOD better; in fact I think that they prepared it for a longer time and Samsung just implemented it empirically (probably using a developer like the one that delivers NoLED)
sure, AOD notification in LG G5 is much smaller and less bright but it gets the job done nonetheless
on the other hand, Samsung should really put a timer for AOD (during night I cannot stop it, just replace it automatically with night clock which is dimmer) and adjust the brightness; they have enough sensors and algorithms in order to achieve that; one forum member suggested that I should just turn the phone with the back side up, but this way I cannot see the led notification in case of missed events during muted....
also, anyone can tell for sure whether AOD or night clock is is more energy efficient???
Im having a problem with the lcd backlight and figured I would ask here. I've had a v20 rooted since Dec of 2016 and luckily have been spared from many of the hardware problems other users here have suffered. Just today, after watching Youtube videos for about an hour at maximum brightness, my main display just went completely dark. With the backlight bleed over from the second screen, I could see my display, but without it on I can't see anything. I'm assuming the backlight has somehow become broken. I'm assuming the only fix for this is a screen replacement, which at this point I don't want to do. Just curious if anyone has had this happen, or if by a miracle this may be bad software that is fixable without replacing parts. Thanks to any and all info in advance.--Philip
Edit-Just now thinking it may have been a thermal issue. Phone is still noticeably warm about 5-10 minutes after a battery pull and being shutdown completely. Smelled the back of the phone and noticed a slight smokey scent. Potentially watching videos at max brightness caused a meltdown? Idk just trying to figure out what the heck happened
Edit 2- So plugging in the phone while powered off to check battery levels has wielded wildly different results. Fist time I plugged it in it was 5%. Then unplugged and replugged immediately and it was 30%, and now a third time it is down to 10%. Wondering if the battery could be bad? Don't have extras to test a different one, but the original shows no signs of deformation. Wondering if a failing battery could cause the main display to disable. Anyways just another thought
Hello. I know its has been a long time but is there any update to your problem. I am in the same boat.
