Hello, is there any way to trigger the screen to turn off (go to AOD etc) when something is closed on its face? I know in the past magnets and other things were used, and even for the SView covers. Is this possible for a DIY?
In the past, doing what you want was fairly easy, there are some apps that do it, I used gravity screen app, even with macrodroid or automate it, but, since the proximity sensors are behind the screen, the whole functionality changed, now, only the phone calling apps can access the proximity sensor, I now rely on the gyro sensor to turn the screen off, it is not the same, but a somewhat useful workaround solution
A small magnet in left-bottom corner does the trick, but only when my original clear-view cover is installed. Without the installed cover (which the phone recognises as installed accessory, I assume through NFC label in cover) the screen will stay on when a magnet is used in the right spot.
I think DIY solution with magnet is difficult, how to trick phone to think accessory is installed and activate magnetic sensor.
The magnetic sensor in phone is located approx 2.0 cm from left screen edge, approx 1.5 cm from bottom.

I was having issues with the magnet in my phone case actually turning on the screen, and taking off the keylock! Pretty crazy, but it was happening. In order to fix this I had to disable the phone from waking up when the keyboard is slid out...not a big deal, I never slid the keyboard out unless the screen was on anyway. The problem is solved.
My question is will this have any negative effect on the phone? Will the magnet in the case mess with the accelerometer or g-sensor? I would hate for the case to cause future issues.
Thanks.
Anybody have any ideas?
I don't know about the accelerometer, but in my phone it seems to mess with the stylus sensor, and turn the phone on and unlock it.
The stylus sensor on the TP2 is not magnetic, but the keyboard slide sensor is. That is why magnets turn the phone on.

Not on mine - I have the universal one and that one has no magnetic unlock mechanism.
As far as I know the G-sensor has nothing to do with magnets and cannot be interfered by magnets. (Have a magnetic button on my shield)
Anytime I turn on the phone after taking it out of the case it thinks it's in lanscape mode. I had to turn off the option of having the phone turn on when the keyboard is slid out.
What I'm wondering is if the magnet in my case will effect this sensor or anything else in the phone?
Thanks.
In short the answer is no. It is in landscape mode because you take the phone out past the magnets to get it out of the holder. There is a magnet in the keyboard sliding mechanism that is used to trigger landscape mode when you slide it out. When you pull it out of the holder the phone thinks you have opened keyboard and goes into landscape mode. In a few seconds when it realizes that you havent opened the keyboard, it goes back to regular mode.
Hope this helps clarify things. Bottom line is that the holder will not do anything negative to phone or degrade its performance in any way. I have two factory HTC cases that both have magnets in them from my Kaisers. Even HTC wouldnt ship somthing that was bad for the phone with them.

Sounds good, thanks for the explanation. I knew it was the magnet playing w/ the KB sensor, but I just wasn't sure if it would have any negative effect on the phone itself. It looks as though it will not!
Thanks.
What's the best way to stop the phone answering calls when I open my case (it has a magnetic catch)? I went to add SlideWakeup = 0 in the registry, but it's already there.
I'm running S2U2, latest version if that makes a difference.
Thanks
I run s2u2 also, no issues when I pull it out...other than the screen is on, which is no big deal, but the screen is still locked.
I was experiencing random screen shutoffs after fitting my galaxy note 10.1 (2014) for a new case.
It took a while before I finally realized that the random shut offs were being triggered by the case, more specifically, when the edge of my case came in line with the edge of the tablet, which is an awesome feature when you have the cover covering the front of the unit.
But the problem is it manages to shut off screen regardless of which side of the unit the cover is on, as long as the edge of the cover is aligned with the units edge. This can be quite frustrating when trying to read while holding the tablet in certain orientations.
Questions: I was wondering if anyone else has experienced similar issues with their cases/covers (a little research seems to indicate this is not an isolated issue and many, if not all, cases/covers suffer from this issue).
1) If you have not, which cases/covers do you use? Do these cases resolve the issue by never aligning the cover to the same position when flipped backwards as when flipped forwards (i.e. skewed slightly short of the edge when in backwards position)?
2) If you have experienced this issue, how have you addressed it? Can you disable the magnetic sensor?
3) Would weakening the magnet in the case perhaps ensure that it was only sensed in the forward position?

yes i have the same problem. pick up A generic folio type case for my P600. Case looks and feels great. Auto wake works brilliantly when I open the cover, but there is the problem of The screen turning off when I flip the cover over to the back and the magnetic edges meet. Dunno how to fix this yet. Tried the magnetoff xposed module but that doesn't seem to work.
I got the Moko slim case and the same thing happens, what I did to circumvent the problem was to put my screen cleaning cloth between the case and the tablet. This prevents the magnet from locking the screen when completely folded backwards, the only thing is that this method will block the camera with the cloth. For me this is not a problem I don't see myself using the camera on my tablet when I can use my SGS3's camera, and this way I never forget my screen cleaning cloth .
I've read about this on other devices on various covers as well. they think it mah be due to the magnet not being properly shielded. dunno any fixes other than get another case.
I hade a cover for my old Ipad and it all so turn off the Ipad when I flipped over the cover.
It did turn out the problem was with the magnet and after getting a new one, the problem was solved.
My poetic slimline work perfectly no issues at all. Love the look and feel, I do want a carry slevee tho for more protection if I wanna bring it out of the house. Or even just to store in the house. But overall love this case.

Get a piece of sheet metal (strip out a cheapie magnetic whiteboard , a few dollars at a variety store) cut to just less than the back of the tablet screen.
Cover it with a thin plastic film (to safeguard from cutting yourself)
It will adhere to the back of the screen magnetically and flatten the magnet's field
Now you can use the device with the keyboard tucked away behind the screen. (you may have to leave a small air gap say 5mm to 10 mm)
This does not affect the normal screen-keyboard functions when used conventionally
Same problem with Galaxy Tab A (Nougat)
There is an option in the tab to turn it off, but regardless what you choose, the tablet still responds to the magnet. Very annoying when you lay down your tablet flat. For now i just put something between the cover and the back of the tablet, like a handkerchief. This works for me, but ofcourse it's not a solution just a workaround. I'm still trying to find a solution.
Did you find any way to turn off the magnetic lock and unlock function? When I backfold my cover (aftermarket), it automatically locks my tab. Which is very irritating. I have Samsung galaxy tab S5e
There wasn't a good search result on a way to disable it via software or hardware mod so I thought I would post the solution I just did on my daughter's new tablet folio.
She has an old S3 Tab so the options are quite limited so figured modification was the only way. I ended up removing 3 magnets until I figured out which one actually did the on/off Hall effect. The smart thing to do would have been to use a magnet to find where on the tablet the Hall effect sensor was first, then remove just that magnet. The other magnets are for holding the clasp in place when the folio is open or closed.
I just cut an X over the magnet location, removed it, then filled it back in with hot glue. On her tablet, the Hall sensor was on the top left (fat arrow). It's annoying to have to do this but there's no other way. I tried the metal plate trick but that looked pretty bad and didn't always work.
Hope that helps someone
Is there a way to TEMPORARILY disable the proximity sensing of the double-tap wake feature of LG G3?
What I want is to be able to wake the phone and unlock it while the phone is in a transparent case (waterproof bike mount, armband, etc.). The phone currently thinks that it is in the pocket and does not wake on double-tap on the screen.
The power button is in the center of the back of the phone which makes it hard/impossible to reach/find when in such a case/armband.
Is there a hidden setting or an app that will make this possible? And once more - I need this for temporary situations when riding a bike. After riding a bike i'd like to re-enable the proximity sensing for pocket carrying.

Cut out a small hole in the plastic right where the sensor is. That's how I solved the same problem.

"waterproof bike mount" :good:
Automaton locker might have a setting that will help you.

The OP has probably solved his problem in the meantime. I had much the same issue, and I wanted to share what I did.
Firstly, yes, there is a way to "disable" the proximity sensor: just cover it with something that a) does not emit, and b) does not reflect IR light. Because of a), a finger does not work, but a piece of black sticky tape does. If only the right of the two little lenses is covered (that is the IR LED), the ambient light sensor even continues to work.
Of course, putting on some sticky tape whenever I use my G3 in the bicycle-mounted case is not the ideal solution. So I experimented with sticking the tape to the inside of the case. That did not work too well, because the front of the case is flexible and never lies flush on zthe screen. I ended up putting some thicker, spongy rubber there.
All this was with Rixen & Kaul's Phonebag M, which otherwise worked very nicely and allowed me to use my previous phone for navigation even in the most torrential rain.
But that spongy rubber blob made the touchscreen more difficult to use, as it lifted the case's transparent front even further away from the screen. So I kept looking, and bought Topeak's new Drybag 6.
It's a bit too big for an L3, but the Drybag 5 seems to *just* be too small - you'd probably get an L3 in there, but not out again. So the size 6 is the better choice. The interesting thing is that Topeak seems to use a different material for the transparent front: it seems to reflect IR light a lot less than the Phonebag's, so I can switch on my L3 almost every time (I'd say, 95% of my attempts worked). I will keep testing it for a few more weeks.
Two other things I find nice about it: the bicycle mount doubles as a belt clip, and it has a ziplock-style - um - ziplock, so it's probably not just resisting rain and sweat, but really waterproof. When I closed the ziplock, it was air-tight.
What I don't really like about it is the flimsiness of the mount - even the screw is plastic, and the case has a lot of play in the mount. I don't think, though, that it can fall out, even on bad roads.
Hope I could help someone.
Cheers
Daniel
Can anyone with a smart cover (the ones with magnet) confirm the location of the embedded magnet on the cover?
I believe book or simple covers, all allow the magnetic lock/unlock of screens.
Need it to emulate the lock/unlock feature using an old non-magnetic cover and some spare magnets I have.
Device : Samsung Galaxy Tab S Wifi 8.4"
I took a small piece of magnetic tape, which has a low magnetic field, and located a spot on the rear, along the right side, near the bottom. Touching the back about 1/2 inch in from the right side and about 1/2 inch from the bottom on the back with the tablet facing you is where it would turn off/on.
If the screen is already off, the magnet will turn it on and it will stay on when the magnet is removed.
If the screen is on, the magnet will turn it off, but when removed it will turn back on.

I found the exact spot! (the red spot at the bottom in the pic)
Works both from front and backside.

Yeah...but if it's a real weak magnet, hardly any pull, it won't work from the front. Which makes me think the switch is closer to the back. Dunno what the OP is doing but it might make a difference in how strong a magnet he uses.
But it's close to where we both have indicated.
Hello, anyone knows the location of the magnetic sensor in TAB A 2016 SM-T580 please??
I have a cover for my tablet - can u recommend an app to auto turn on / off screen when I open / close the cover, because HOME button is quickly wearing out! Thanks.
I seem to remember that there were several complaints about their tablets shutting off when closing a third party cover. It turned out that there were magnets in the cover that affected the on/off switch. Maybe you could do a search to find out what cover they used and buy that cover. I may have seen that post somewhere on another forum also. Try a google search also as it may turn up the post you need.

The tablet has built in functionality for this.
most folio cases have magnets in them that activate the screen when you open them.
That being said the magnet can temporarily interfere with the Waccom layer of the screen used to get Spen input. (the pen will stop reading accurately/at all in the areas affected by the magnet.)
there were a lot of reports of the magnets permanently affecting the screen but the official word is that if the magnet is removed from close proximity to the screen the issues will eventually go away. (This was a big deal a while back because even Samsungs own folio case has magnets)
note that not everyone reported the issues so I'm pretty sure it has to do with how strong the magnet in the case is.
if you use your pen a lot I would stay away from those cases.
on the other hand if you don't use the pen then it wont affect you.
There are apps to let you double tap the screen to wake it (even for android versions before it was supported) which would save the physical buttons some wear but I suspect you would take a hit on battery life with that option.
The answer to just about everything: Tasker.
There's a how-to for this particular setting here. Battery drain is pretty low, about 2% every 12 hours or so.
Only flip covers with a magnet can use the system's inbuild auto-on/off functionality. Everything else needs to use the proximity sensor.
There are three types of flip covers, two of which use a magnet.
One is a strong, single magnet. This is the cheap option and causes problems with the Wacom sensors, which are also magnetic. You'll find this in pretty much 90% of all auto-on/off covers, especially the cheaper ones. The first Samsung covers also used this method, until they figured out it was a terrible idea.
The second is a ring patterns of thin magnetic strip woven through the entire back of the cover. This is used by most expensive brands (Like Samsonite), and doesn't interfere with the Wacom sensor.
The third are the most common one: Covers without a magnet. All these do is protect your screen.
