Disabling screen-on/wake-up reaction to change in power status? - E 2015 Q&A, Help & Troubleshooting

I've noticed that my rooted XT1527 2nd Gen MotoE will automatically "wake up"/turn it's screen on whenever it recognizes that it has been given a power source (or the power source has been taken away).
Basically, every time I plug in, or unplug the power cord, the phone's screen flicks on in recognition of the change in power status. I want to disable this and have the phone screen only turn on if I physically press the power button.
The reason I'm asking is because I am experimenting with charging my phones with solar panels. Things work great when it's very sunny out, but when it's cloudy, even though the phone stays plugged to the solar panel, the charging source flickers in and out with the clouds (which seems to be the equivalent of plugging and unplugging the phone from the commercial charger in rapid succession). When this happens, the phone's screen turns on in recognition of either gaining or losing the power source, and on cloudy or rainy days, this process happens so frequently that the phone screen essentially stays on all day and slowly drains itself of battery much more quickly than it would have if it didn't feel the need to turn on the screen every time the power source came back or went away.
Any suggestions for how to disable this "screen on to recognize change in power status" feature?
My phones are rooted and I've made some simple firmware modifications to them, but I'm definitely a n00b.
I won't go into the details, but I'm using the phones for scientific research, which is the reason for the solar panels. I want my phones to be able to stay on and collect data, but I don't want that screen waking up and flicking on every time there's a change in power status! I'd love to be able to get rid of this feature! Any ideas?

[Q] HTC Amaze bricked?

Hello XDA,
First of all, thanks ahead of time for helping me out.
My HTC Amaze 4G is rooted with the regular Stock ROM - in other words I only used my root to change the processor speeds (usually make the CPU slower to increase battery life).
I was watching a video yesterday using MX Video Player which was decoding the video in Hardware mode. Other details about the video is that the video format was h.264.
I was watching the video, and then all of a sudden, my phone freezes up, and nothing works at all. I am unable to sleep the screen, none of the capacitive buttons or the volume buttons work, and holding down the power button is also useless. I waited a few minutes, occasionally trying to turn it off by holding down on the power button. After nothing happened for many minutes, I removed the battery (which turned it off), and then reinserted it.
Because Android has hideous boot times when not turned off properly, I decided not to wait, and instead went to bed. This morning I try and turn the phone on, and it wont budge. I try a number of things to get it on, such as removing the battery and the SIM card, and many other combination of tricks. Once again, nothing worked. I should note that when plugging the charger into the phone, the orange light does appear occasionally, which means that sometimes it will show up, and sometimes it wont. Also sometimes when I plug the charger in, the orange light flashes on and off, sort of like a notification, for about 10 seconds.
It would be awesome if someone could help me out, as the carrier I'm with sucks at repairing/replacing phones because they are super cheap and annoying (Mobilicity).
Thanks,
Robert

your battery most likely went bad because you didnt pull it when the device locked up... so you may need a new battery if you ever want to boot again.
next time if your phone locks up, pull the battery instead of letting it go.
Your battery is dead. You should've booted it right back up after you pulled the battery. One of the issues with root and the wrong recovery is not being able to charge the phone when the phone is off. Get an external battery charger or find someone with the same phone or battery and start it up.
Now...please check the other threads requarding Amaze being bricked or unable to power on.

Thanks for the quick response everyone. Can anyone point me to where I can buy a new battery?

Thanks for the quick response. When you say pull it, what is it?
Thanks!
Pull the battery out, try ebay.
Over 10000!!! You bet I am.
Buy a charger that allows you to charge the battery outside/ independent of the phone. Ebay has those for 5 bucks? Each

I had this exact problem.
If you rooted your phone a while ago you installed a recovery that did not support off-charging. So when you plug your phone in, if you look VERY closely at your phone, you will notice a green menu that you should be able to move up and down with the arrow keys.
The only way to fix this is to do one of two things.
1) The method I used: (NOT RECOMMENDED AT ALL, EXTREMELY DANGEROUS)
Take the battery out of your phone, get a 9-volt battery, and two wires.
tap the wires to the respective (+ and - leads) of the battery a couple times.
KEEP IN MIND, YOU ARE DEALING WITH A LITHIUM-ION BATTERY, IF YOU OVERCHARGE OR MISCHARGE A BATTERY. IT WILL EXPLODE, POWERFULLY.
2) Buy a new battery and install 4EXT AS SOON AS POSSIBLE.

S3 suddenly wont turn on, bottom lights and charging led work

Hi All,
I was out a couple of days back and my battery died. No trouble, come back home and charge it up. Worth noting that in recent months battery performance has been poor with a full charge only lasting about 8hours or so. I put this down to a new ROM I flashed as well as natural deterioration (18 month old S3).
Plug into the wall, red charging LED comes on, but the battery splash screen does not. Tried another charger...same. Thinking nothing of it I go to bed and wake up next morning to be greeted by a green charging LED. However, still no battery splash screen. I try to boot...it doesn't. When I "power on" the bottom LED buttons do light up white and go off after a few seconds. When I press the hold button again, they also come on for a few seconds. If i press the hold button while the button LEDs are on, they go off.
This makes me think the screen has broken as both the hold button and the charging LED is doing what it would do...but without any screen activity. However, it was not dropped or put under any pressure in any way. I have opened it up and also made sure the ribbon is undamaged and connected properly. I have tried calling the phone to no avail. It also does not vibrate or make any noises. Perhaps the battery doesn't have enough juice? Its as if its on the battery splash screen, I just cant see it.
I should mention the screen is infact cracked from an incident about 6-8 months ago. It was however, fully functional. Presumably, this will unfortunately stop me from sending it in. It was also using a flashed rom (CM11) and a flashed kernal (Boeffla).
I used a multimeter and measured 3.96v across the battery so that's fine. I can't test the current as I cant break into the S3 circuit and I dont have a resistor on hand to put some load on it.
Next steps?

Try to put it in odin mode (power+vol down+home then press vol up to agree that you are now in odin mode). You should see it in odin.
If you dont see it, your battery or energy system of your phone is broken. Otherwise your screen is probably broken?.

I've managed to get it into download mode and too show up in odin. I can also get it to show the files in Windows if i wait after holding the power button.
This all indicates it is in fact booting up and the screen is broken...
...BUT...no sound...no vibration...and no calls received
Its as if its only half on. Beginning to suspect a catastophic motherboard failure. Is it possible the battery is at fault? Its as if a whole power rail providing for the phone receiver, loudspeaker, vibrator and screen has gone.

Turn off screen while charging broken in 6.0.1 update?

Just got the update to 6.0.1 today. With 5.1.1 I used to double press the side button to put the watch in theater mode and turn off the screen while charging. My v1 moto 360 developed some screen burn in after about a year from the charging screen, so I now turn it off on my v2 while charging. But with 6.0.1, the screen will not stay off, the charging screen turns back on after 10-15 seconds. Anyone else also notice this with the new upgrade?

Yes, noticed it last night - I normally put it in theatre mode too for just the same reason, but now it turns back on after a few seconds. I've tried changing the developer options for 'Stay awake when charging' to enable/disable and it makes no difference
EDIT: Tempted to try the 'Slumber' app, but read some horror stories in reviews...
Thanks for the confirmation... I have an support inquiry into Motorola, hopefully they can fix this in another update. I had some wackiness with the contacts section after the upgrade, so i did a factory reset. It did fix the contacts problem, but unfortunately the screen still turns back on when charging.
please keep us updated. this is ridiculous. they fix one thing and break another. Motorola is ridiculous.

Same Issue
I also have this same issue. (Moto 360 Gen 2, 6.0.1)
Tried a factory reset after upgrading to 6.0.1 OTA and the screen turns on after a few seconds of being off while charging.

Figured out the issue
Hello All,
I have figured out the issue. Motorola changed how it works.
You can no longer double click to go into theater mode set it on the charger and have the screen stay off.
Now, for whatever reason, you need to place it on the charger, wait for the charging screen to open and for the charging animation to finish / slightly fade, press and hold the side button until it fades to black, your screen will now stay off until you remove it from the charger. Took me a while to figure this out, ha-ha.
I have tried this several times in a row and the screen does remain off.
Hopefully this helps you guys as well.
Thanks,
-th3r3isnospoon
PS, if it doesn't work, reboot once then follow the above instructions.

hmm....i couldn't get this to work, even after a reboot. when i press the side button, the app list immediately comes up and if i hold it longer, it switches to the black and white ambient mode screen, which i guess is better than the charging screen. But I couldn't get the screen to turn off like with 5.1.1. If you keep holding the side button for too long, the watch does a hard reboot. Anyone else manage to get this to work?

I just tried this, and couldn't get it to work either. When I hold down the side button, the app list appears, holding down longer shows the ambient watch face. I have the 42mm version and have Always On turned On.
I did try turning off always on screen too, I thought it might be related to that, but no change
Does not work for me either, even after a reboot...
My solution (for now) to reducing the amount of heat the watch is subjected to on the charger (I normally charge overnight) is to use one of these WiFi controlled plugs:
http://www.amazon.co.uk/Watts-Clever-Controlled-Monitoring-Features/dp/B00UQOPM8U
I make sure it's turned OFF before going to bed, turn off the watch (optional) and set it on the charger. Set the timer on the InPlug to come on 1hr30mins before I get up in the morning and then automatically switch off. That means the watch and charger come on, get charged before I get out of bed, and the InPlug switches itself (and the charger) off again after 1hr30mins so the watch/screen is only ever subjected to an hour and a half of charging and the associated heat/screen burn.
The other option is to have it on when you go to bed and switch off 1hr30mins or 2hrs later, but then the watch is on all night using up the charge.
You can set the InPlug to do the same thing daily, so it's a 'set and forget' kind of thing. (Other makes are available, for example, Belkin).
I noticed that the charging screen seems dimmer (maybe it's just me) than before the update, so maybe that will reduce the chances of any damage.

doesn't work at all. holding it down brings up app list, thats it.
Hi! Excuse me for the OT question, but since you talked about it...how do you do a factory reset in 6.0.1? The reset option is no longer in the settings menu...
In settings, go to bottom and choose "unpair with phone" that performs a factory reset.
I have the same issue, expect a firmware upgarde soon from Motorola.

Do you know of a firmware update coming that will fix this or are you just speculating?
I'm currently using Slumber for Android Wear, and it's free with no weird permissions.
It appears in the app drawer on the watch; you just have to activate it before you drop it on the charger.

Cure for "phatom touches" problem

As many of us are aware, there is a issue that can occur with a Nook Tablet going crazy with phantom touches. Essentially it looks as if you are tapping on the screen when you are not. It usually happens very quickly, one minute ok, the next everything is getting tapped all over the screen. This can cause data loss as the device thinks you are touching the screen. For example a file you were working on may abort before saving as it thought you hit "close".
I have been bugged by this issue on and off. Some people replace batteries to fix the issue, and while that will fix it 99% of the time, there is an easier (and cheaper way).
The problem appears to be the newton loses battery calibration. There has been talk in the past of deleting the battery file via CWM or other Android app that deletes this file (or even doing it manually with a file browser app, which may need root access). This battery file is only data since the LAST time you charged the device. Not the calibration data. And this file is deleted automatically everytime you plug it in to charge.
How I fixed it
After a lot of research I found that many Android devices there often a way of recalibrating the battery charge system. The steps are:
1. If you get phantom touches hit the power button as fast as you can to put it to sleep ande prevent anything occurring you might not want (aka a file deleted you wanted to keep etc).
2. Charge the battery to full, until the green light is lit on the charge indicator located on the Nook Tablet charge cable
3. Unplug the device from the charger
4. Use the Nook Tablet for 20 minutes with a high drain app (aka watch a video)
5. Plug the Nook tablet back into the charger and wait until the light turns green again.
6. Repeat steps 2-5 several times. I would suggest 3 or 4.
7. See if you get phantom touches again when the Nook Tablet power gets low. If you do try steps 2-5 again several more times.
In my experience after a few times of this, I no longer had the phantom touches issue.
Why it happens
I am not sure all the details as to why, but one time I do know for a fact that one time it happened after I had the tablet on the charger with a full charge (I had not got around to unplugging it yet) when the power to my home failed. It came back on a few minutes later but that night when I was using the device I got phantom touches at about 50% power left. Which I never had before. After doing the above method it is working fine again even down below 15% power (which I never let it get that low normally).
I suspect that the power failure caused the charger system to recalibrate and since the battery was already at full, messed up the whole system. I also would NOT leave the Nook Tablet on a charger for long periods. If it sits at 100% for a long enough period it is possible for the battery to drop down a little and start charging again. This could start a recalibration again, bringing back the phantom touches issue.
I have not posted until now as I was not certain what fixed it before. If it was the charge to full, use for 20 minutes, then charge again method or turn it off then charge method worked. I tried several before and wasn't sure which one worked. Now I can say the put to sleep, charge, use, charge again method does work. But don't turn off the device then charge if you can help it. If the Nook tablet is powered all the way off (not sleep) doesn't seem to do a battery recalibrate. Or at least my best experience is to plug it in while in sleep mode, charge to full (green light), use for 20 minutes, and then charge again.
Sorry if this has been posted before. But a quick search didn't reveal any hits.
UPDATE:
Upon further tests, often powering off the device fully (holding power for 30 seconds or pressing for 5 and saying yes to the popup to power off), then plugging it in, letting it turn on and charge to full will fix the problem as well.

Help! Can I turn on my HTC One Max without using the power button?

My One max's power button isnt working and my phone died. is there anyway to get it to turn on? I had the bootloader unlocked, cyanogenmod 13 and root.
Backstory: A while back, my volume keys were acting up and my phone would constantly go to low volume like if i was pressing and holding down the volume down button. Next thing you know, the power button isnt responsive and I cant wake my phone. The only way to get it to wake up was by getting a phone call. Sure enough I failed to keep my phone's battery charged and the phone died. I charged it and the battery is at 100% but i cant seem to turn it on. any ideas? thanks, I truely appreciate it. I know im going to have to get a replacement flex cable, but I dont want to wait for shipping to get it turned back on.
From one Moe to another...
My One max has behaved exactly like you described this summer and the last summer. Happens every time I answer a phone call with sweat going down my ears, it gets downright humid here! Usually fixes itself after a few minutes in front of a fan in an airconditioned room. By the end of last summer, I had to get the button strip replaced. Hope I am more careful this summer in order to keep it all in order this time around.
Last summer when I realized the power button was on its way out, I used Sense Toolbox (an Xposed mod) to set my device to wake from volume buttons. Of course that doesn't help if the phone dies from low battery like in your case.
(Edit: I also have a custom setting, I think also applied by Sense Toolbox, that wakes the screen when plugging in the charge cable. But this, too, only works when the device is fully booted and running.)
Maybe someone else can help with an obscure key combination. I dunno, maybe something like holding down the volume down button while plugging the charge cable in?!? Cuz my device (s-off, rooted, twrp, lollipop stock) starts charging in power down state, and I can see the splashscreen transition into the TWRP screen briefly flashing several times as it eventually gets into the charging screen (big green battery with percentage on the screen).
Cheers from Pakistan and Eid Mubarak!
