Kindle Fire HD keeps turning on and off !? - 7" Kindle Fire HD Q&A, Help & Troubleshooting

Hi
Has anyone had this problem?
It doesn't turn off when I'm working with it , but when I turn it off It keeps turning on automatically , the timing is random.
Help please

Make sure you don't have a case with a magnetic latch, Those often trip up the sensors in the HD. If you do, the easiest thing to do is flip the case around, so that it opens the wrong way. That will get the magnet away from the sensor.

KFTHD 7 Auto Dimming By Itself. How to Stop This?

I have a Brand New Kindle Fire HD 7. I have it Rooted with Apex Launcher. From Time to time the display just shuts off on its own. I have Screen Timeout set to never, but it still continues to do this. Does anyone know how to make this stop? Maybe through the build.prop or another way. If anyone needs more info just let me know.
Mine was driving me crazy with that, but I finally figured out the problem; It was the magnetic closure on my case setting off the dim command. Apparently Amazon has a case that wakes up/sleeps the HD automatically. I just flipped my case around, so that now it opens the opposite direction of a book and it solved the problem.
Holy testicles I have a case with a magnetic latch too that has to be it!
Mine was opening with the charger ports close to the magnet latch. I'm not using an hd case on for some other tab it's a little small for mine but it works and its real leather. I just flipped it around so the ports are further from the ports hopefully this solves it. Thanks button hit!
After 24 hours of testing this problem is fixed it was the magnet on my case Thanks!

[Q] Disable Magnetic Sensor?

Is there any way to disable the magnetic sensor on the N6? I have a smart cover that keeps constantly turning the screen on in my pocket and it's killing my battery. It is a very nice luxury case and I don't want to damage it or replace with another cover. I tried finding an app that would do it but no luck. Any help would be greatly appreciated!

Dont think there is a way to disable it yet.
Although i read elsewhere its located in /sys/module/ and adding a '0' or 'false' to the value will disable. Issue is still not located the magnetic sensor, older devices it was in /sys/module/lid/parameters/lid_enabled.
But no luck on N6 yet
has anyone had any luck using an app to accomplish this?

Found nothing to disable the magnet sensor.
Installed Xposed and a MagnetOff app. But it did not disable the magnet sensor.
Because I cannot disable that feature, I decided to use it.
On the outside of my belt case I attached a small magnet (glue) and now my screen is always off when the N6 is in the case.
When I take the N6 out of the case the screen turns on. No need for pressing a button.

you sure the screen is always off when it's in your case? like the OP, I found that my screen would periodically come on when using a flip case that has the auto on feature (while closed).

When de magnet is close to the circle with the Motorola logo the screen is switched off.
I am using a flat neodymium magnet with a diamater of 10 mm.
Because the case is partly open at the top, I can see that the screen is really off when the N6 is in the belt case.

When you are unsure if the screens will be turned off when the N6 is in the case, use a stronger magnet.
I mounted with glue a magnet at the outside and put a second one on the inside.
So I am using two small magnets.
any developer willing to dig into this issue to try to find a solution?

[Q] Magnet keeps activating screen, drains battery

I found out that whenever a magnet is close to the screen (like the ones to be found in auto wake/sleep smart covers ) the screen will go off, as it should, but wakes up again after 10 seconds.
It will keep doing that forever: wake up, sleep due to inactivity, wake up, sleep, etc etc. It is obvious that the magnet is somehow triggering the screen to wake up.
You can easily reproduce this by placing a white board magnet on the device (place it between the hours and minutes of the lockscreen clock). Just wait and see what happens.
This means that you are certain to drain your battery when your phone is idle, sitting in a smart cover like the official one from Casemate.
I would love to use the smart wake, it worked flawlessly on the Nexus 5 but works only as a battery drainer on the N6
Is there anything that can be done about it? or is it a hardware issue?

The magnet sensor of the N6 is under the M logo at the back.
When there is a magnet on the M or there above on the display the screen is switched off. And stays off, but . . . a weak magnet that moves a bit away may cause the problem you described.
The magnet sensor cannot be disabled (could not find an app). The solution is to remove the magnet from the cover.
BTW this may occur also with a (belt) case that has a magnet closure. That closure must be about 1 cm from the M logo.

Thats interesting, i didnt know the sensor as at the back. When i place the magnet there, the behavior is different. It does not go on entirely, instead it goes to ambient display. But not consistently... Weird.
Anyway i purchased some cheap neodyium magnets from eBay that are supposed to be quite strong, maybe that will have the desired effect. I plan to attach them to my spigen cover.

If you want to be sure that the magnet sensor is active (screen off) you need probably more magnets.

That's OK, they come in ten
I've observed this too. I wrote a Tasker app to sound a notification everytime the screen turned on (since my casemate flip case was closed) just to prove I wasn't crazy. mine turns on with every magnet (auto sleep) case I've tried. this is with stock software.
after posting about this issue in one of the case threads in the nexus 6 accessories forum, it turned out not everyone experienced this issue. or at least they didn't know they did.
I just wanna know how Google can even sell the casemate case in the play store when this issue exists (at least for some)...
Xposed has a module that turns off the magnetic sensor. I have no idea if it works or not so look at the thread for it. My phone is naked so I don't have this problem.

On the hard cover I mounted a small round metal plate (glue) at the same height as the M-logo at the back.
I did choose that place, because it is above the coil for wireless charging.
But. . . . the problem is that exactly there the magnet sensor is located.
So when the N6 was mounted at the neodymium magnet, the screen becomes black.
The first thing I tried is to disable the magnetic sensor with the xposed-module. Unfortunately is does not work on the N6 with Lollipop.
Xposed need to be updated.
My hardware solution is to glue the metal plate on the cover, about 1 cm below the M-logo. And then wireless charging is not possible (metal becomes hot).
I am using at the moment two ultra thin covers for the N6. One with metal for car use and another original to allow wireless charging.
Same problem with the official case mate cover, it is useless. I pulled mine from a shelf this week wondering why I wasn't using it, two days later "ahh, now I remember...". One of the many reasons I don't like this phone. Generally, Motorola does a nice job but when they don't, the phones are real duds. At least this problem is better than those with the screen protectors keeping the screen off when you make a call.
Someone mentioned a fix using gravity box for the ambient display activating in a pocket and causing phone calls and texts inadvertently; I think it was setting to keep the screen off if the proximity sensor was active, like in a pocket. It would probably work for this problem too.

When a magnet stays close enough to the M-logo there is no problem. But most leather cases are flexible. Little movings will continuously activate and deactivate the magnet sensor. So the screen is frequently tuned on.
We need a software solution that turns the magnet sensor completely off.
In the meantime you need to remove the magnet from the case/cover and replace it with Velcro.
In some types of cases the magnet is not in the center. Put the N6 in the case with the M-logo turned away from the magnet.
When the magnet is about 1 cm away from the M-logo, the magnet sensor is not activated.

The update really didn't make a difference for this but I did notice that for the official cover, either I received a defective one or the magnet is extremely weak. Velcro won't help as it doesn't have a flap to keep it closed. I guess the prosimity sensor only works with a phone call.

Moto G 2014 XT1068 Screen keeps going black

Hi,
I have a Moto G 2014 dual sim 5" phone (XT1068). For the last 6 months the screen as been turning black when I'm using it like it has gone to sleep. I hit the wake up button and the lock screen is displayed. I swipe the screen to unlock the phone and it then turns to a black screen again. I have to do this for around 30 seconds until the phone behaves normally again. It happens at random times. I have tried doing a factory reset but this didn't fix it. I then unlocked the bootloader and rooted it and stuck a custom ROM on it (Blisspop) but it is still doing it! Anyone know the reason for this? Thanks.
Tried reflashing stock?
Do you have it in a flip case?

Yes....it is in one with magnets that wakes it up when you open the flip case.

Same here. The magnets also turn the screen off. When you flip the lid around the back, they are strong enough to activate the sensor and turn the screen off.
There is an Xposed module which you can use to control this behavior. From memory (I don't have it installed right now) you can selectively tell it to ignore the turn off message but keep the turn on message. I think there was something about turning it off using the proximity sensor as well, so it will still turn off when you close the lid.
In fact, I'll install it again, I forgot how useful it is.
UPDATE: The Xposed module is called MagnetOff. If you want to have your phone turn off when you close your case, you'll need to look into an app to use the proximity sensor to do it (I used to use Tasker).

You might well have cracked it! I never thought of this. It is my wife's phone and she always folds the cover around the back. I have ordered a non magnetic wallet and will test with that. Is this 'Xposed module' an app that you can download from the play store? Would come in useful if thsi is what is causing it. Did you phone suffer from the same thing? I was already fighting with Motorola about the warranty cover because I had unlocked the bootloader and rooted it. If this is all it is then thank you so much!!!!!

You're very welcome, hopefully it solves your problem.
I've got into the habit of keeping one finger in between the cover and the phone when I flip it around, so I don't use the software anymore. The main reason I originally found it was for the magnetic phone holder in my car. If I put it too much too the left the screen would turn off and keep turning off when I turned it on, but I don't use it any more.
That's totally fixed it! Thanks so much. :good:

Stuck in weird screen after factory reset

I factory reset my phone to wipe all personal data and make it as new again. But as soon as it turned on again, It displayed the Huawei logo as always, then the logo of my carrier, and then got stuck in this weird screen (see photo) where nothing i press or swipe will give any reaction.
Tried the hard reset by pressing up and down volume and power at the same time. A different screen appeared for a second mentioning EMUI and below Installing update 5% and then suddenly an error appeared (see second photo).
Please dear experts here, let me know what is going on... I love this phone and was very happy with it until I decided to the factory reset which on other phones always helped me get original performance back.
EDIT: well this forum wont let me post links as a new member, i guess that includes images. so let me try like this

hope that works
No idea why but it's showing the smart cover lock screen when its supposed to only show with a Huawei P9 smart cover that is closed on the screen.
oh so you're saying it's showing the screen as if there was a cover on it? that would make so much sense because i've had the display replaced just a day before... so maybe they didnt do it right and now the phone has some pressure on the LCD and thinks it's a cover?
Yes, exactly as you said, it is thinking the phone has a smart cover on it.
How the smart cover works is phones is that they have a magnet on the smart cover that where if you were to put a magnet at the exact spot on the screen it will trigger the hall effect sensor (The spot where the phone would be told that the smart cover is closed).
Yeah sounds like something went wrong with the screen replacement but it's rather rare for this to happen as it would require an magnet to trigger the smart cover sensor.
so weird... i hope they can fix that issue it's still not working but i will bring it back today. thanks for explaining how the smart cover works!
do you know by any chance on which part of the screen those triggers are? or that trigger magnet, if there's only one?

did you manage to resolve the issue? i currently have this problem
smart cover works with magnet. One of the quick fixes is to take a magnet and pass it over the screen. As i believe because im working for huawei they send us some devices and seems like the microphone or the speaker was moved. Those two have magnet and so it conflicts with the smart cover. Try as i said to pass a magnet from the screen and see if that would fix it. I am going to highlight That, This is happening due a hit, drop or misplaced speaker or microphone.

im not using a smart cover and i cant get onto my phone because it shows the screen that the smart cover would show if it was on. if only i could get onto my phone somehow and turn the setting off:crying:

then you are going to have a factory repair because its either the mic or the speaker in a bad position and its activating the smart cover since both of them have a magnet in order to work.
