Speakerphone during phone call on facedown?

I had this feature with my TP2, and used it a lot.
Is there any mod of some sort I can install on my EVO 4G to allow the speakerphone to automatically activate when the phone is facedown?
I'm sure others would be interested in this as well.
Thanks!

yea there definitely is because it worked like that on the hero, someone will make it happen hopefully

I did not know that about the Hero!
Hopefully some awsome members here at xda could port that mod/app to the Evo sometime soon...

bump!
I'm curious to know if anyone else has heard anything about re-instating this feature on the EVO 4G!
Thanks

I would def use it

Me too why would they remove features out of sense?

i'm interested in this too, loved it on my tp2

it's 3am, in my bed, talking to someone (doesn't matter to who, that's not the point here). i flip to my side, incidentally making my phone's orientation matching the criteria - facing down, out the blue now i'm on speaker (!)... lol, not that i'd be doing this but this is one case where this "feature" would be more of a "bug"

I'd imagine you could code it not to look for a certain orientation, but to look for a rate of change of the Z axis that would indicate that it suddenly stopped face down on a surface. If it is coded like that, in your scenario you would only trigger it if you brought it off your face than slapped yourself with the phone. The impulse you get from a hard object is much different from a soft object and I imagine that for most people, they're talking about tables and counter tops here which are much harder than your face.

It would be based off of the proximity sensor.

use flipit in the android market, works pretty good

+1 on this. Works just like the TP2 did

+2 so far works awesome, just like the TP2

Awesome! +3 Just what I wanted.

does anyone know if there is a way to hang up without turning the screen back on? Sometimes when driving and talking on the speakerphone its such a pain to wake the screen and then press end. Sometimes the other end hangs up and i end up pressing a button on the home screen instead. annoying not having a hard button for hanging up!

Is there any flip cover case that can wake up and sleep Xperia Z?

Hi! Im searching a flip cover case that can unlock and lock the phone. Does Xperia Z even have that function? I was thinking about it, becasue it have magnetic field sensor.

I never see a flip cover with that function.

In my Friend Samsung Galaxy Grand I installed app: Proximit Smart cover
https://play.google.com/store/apps/details?id=com.danielling.proximitysmartcover
It doesnt look to "professional", but its doing its job.
It use proximity sensor to wake up/sleep phone. You can set different timers so you dont set sleep accidentally when you cover sensor by hand.
Also it have unlock option.
It doesnt take battery at all.
I hate covers and bumpers(even if I had one with wireless charging), but my friend said that he dont see any battery drain problem, so it shouldnt be a problem on our Xperia Z.

I've been using Gravity Screen with my flip case and it's been working quite well.

Hey guys,
i was searching for such an app, to automaticly turn on/of my Moto g2 when opening/closing the flip cover. I tried both apps, but in both only turning on works (but it doesnt directly switches to the menu, where u can just enter your pin?). Turning off the device isnt working at all?
Do u know why? Both apps got the special rights to be able to do that. Im using Android 5.0.2. Some help would be nice . Bye.

Does anyone know where I can buy Flip case for Xperia Z?
Thanks.

Stop being lazy.
Press that power button once to lock and an other one to unlock.
You know, most of the roms nowadays have "double tap to sleep DT2S" function included.
What's that hard about it?
Once the proper settings are done it's a breeze.
Do you really wanna pay money for some crap it might not work ,crap that requires you to install aditional apps which will inevitably eat more cycles and ram and drain your phone's battery?
Well, then , go ahead...
Be my guest.

Amazing input @gorillanobka thank you very much for it. Be our guest and go ahead to find another half year old topic to review.
And no, most of ROMs doesnt have that. Its Kernel feature not ROM, and most of people dont like to mess with kernel because its not worth it sometimes(eg. stability of phone & lack of time to mess with it + battery consumption that is really small but is there)
And being lazy have nothing to do with it(I have no idea where you get that) its actually cool feature, and case also protect phone if you work in harsh environment(because you know that people work and not only sit in home?) And money? its cost less than candy :]
Also in terms of battery it dont change too much, if not at all, its keep alive proximity sensor... that would use the same amount of energy as keeping alive screen touch for DTW. Because you know... people actually test such things and not take informations from sky :]

@Akinaro I'll do my best to find some other old ass topics to review. The thing is there are not too many suckers around to bite which tends to spoil the fan.
As a matter of fact ,you're the only one.
Well done you :laugh:

How Moto Actions detects wave to wake

Hello,
This is a little Moto Maxx/Droid Turbo related. I currently have a Droid Turbo. It has/is still a great phone. Work bought me a Galaxy S7 and one thing I have trouble with is the lack of responsiveness of the sensors to enable Ambient display. (I have no interest in AOD).
I have checked the proximity sensor on the Turbo and the detection height is roughly the same as on the S7 but the results are terrible on the S7. This leads me to believe the droid is using more then just the proximity sensor for detection.
I figure i may be able to reproduce this in tasker but...
Does anyone know what the Maxx/Turbo are using for detection to turn on ambient display per moto actions?
Thanks

Has IR motion sensors also.
Sent from my official open market LG US998 V30+

I think it is ambient light.
this makes sense as early versions of moto actions had issues at times when auto brightness was enabled. I fear the task i need will be a huge battery drain when implemented outside the core system.
Basically, look for a decrease change in ambient light. when it hits, toggle AOD on for 3 seconds, then toggle AOD off, then go back to monitoring ambient light.
change needed to trigger woudl be lower during nighttime hours.
* doesn't work anyway as turning AOD on when the screen is already off does not make it show.

I've already answered, but I'll repeat myself. It's not just the proximity sensor. The Quark -- in this case, Droid Turbo -- has IR motion sensors. That's why wave to wake works better on Quark than that Samsung.

I have already replied but I'll repeat myself. I imagine the difference is the droid is detecting a change in ambient light levels rather then just proximity, which is why it performs better.

I've already answered but I'll repeat myself. No, the 2014 Moto Droid is not detecting ambient light better than an 2016 Galaxy Samsung S7. For Wave to Wake, the Droid Turbo has INFRARED(IR) MOTION sensors the Samsung Galaxy 2017 does not have. Clue: Wave to wake. MOTION. Has nothing to do with ambient light.
And ambient light has NOTHING to do with "Ambient Display".
The Quark can detect motion even in the dark, due to INFRARED (IR) spectrum sensors. Has nothing to do with light levels or the "auto brightness" of the display.
Whereas the 2016 Samsung S7 does NOT have IR sensors like the 2015 S6 did or like the Moto Quarks. So, as I said from the very beginning, there's your difference.
IR SENSORS MISSING IN S7 and S7 EDGE
Samsung taketh, too, as the infrared sensor at the top of the Galaxy S6 and S6 edge is now gone in the S7 and S7 edge.

By the way, ambient light has nothing to do with "Ambient Display". "Ambient Display" is a just a term for a black & white display notification system on the display. "Moto Display" is very similar, and is built on the infrared sensors (when you wave your have over the screen) -- but in custom ROMs even on Quark we use Ambient Display as as a substitute, since Moto Display is proprietary to Motorola stock firmware. Our Quark CM dev at the time replicated the Moto Display so well -- he REALLY worked on the IR Sensors part, which is why I know about it -- it's actually called Quark Ambient Display, and uses the same Moto IR sensors you are trying to ignore.
Android's Ambient Display on other phones is often not as good as our Quark Ambient Display or stock Moto Display, because some phones do not have the INFRARED (IR) motion sensors to do it properly. Some phones may have to rely only on proximity sensor. Like the Samsung Galaxy S7...
If you're really interested, here's a discussion of the 2014 Moto X which has the same IR sensors as the 2014 Quarks:
https://forums.lenovo.com/t5/MOTO-X-2nd-Gen/Solved-Motorola-Moto-X-2014-Sensors/m-p/3120329[/QUOTE]
supposedly are three infrared sensors for movement.

The sensors work completely. The lower sensors are not bug. It is a new feature of Motorola.
Lower sensors operate at a height of 10 to 15 centimeters. The up sensor up to an attitude of 1 centimeter or less.
In this way, it covers the entire space (from 1 to 15 centimeters) fully functional by Moto screen.
You will see that it works perfectly.

To be more precise, there are three IR emitters, two on the bottom, one to the right of the top earpiece. These provide the IR light that will reflect off your hand. The reflected light can then be picked up by the single IR detector up top. As long as your hand is within the field of view of the detector, it will work just fine. It seems the detector has a conical field of view, so as long as your hand is within that region, it should work
Click to expand...

They are specifically talking about the IR sensors triggering Wave to Wake at various distances. Top right is for closer, bottom two is for higher distances.
Your Samsung Galaxy 2017 does not have these IR SENSORS.

Exactly, it is detecting a change in the light that is detect by the sensor when you wave your hand over it. As in a light level is detected. In this case reflected ir.
You also seem to be a bit testy. I also don't remember claiming the s7 had an ir sensor. Just that the wave to wake was kicked off by a change in the light detected. Perhaps in the world of ahole responses infrared is not consider on the light spectrum. I don't know for sure, I am sure you can speak to that one though.
>>>

So the detector detects a change in light. You should go have a drink or something.

But has NOTHING to do with ambient light or any kind of light you can see. It will even work in pure darkness. The IR is emitting INFRARED light -- the same way security cameras work in the dark. It's a spectrum of light the human eye can NOT see.
It's not "light" the way you are talking about.
Infrared radiation is electromagnetic radiation with longer wavelengths than those of visible light, and is therefore invisible to the human eye. It is sometimes called infrared light.

The Moto Quark has those emitters/receivers, PLUS proximity sensor -- while the Galaxy Samsung S7 only has proximity sensor.
No, you didn't claim the S7 had IR sensors, but in my very FIRST reply, I told you the answer. You wanted to know why the Droid Turbo (Quark) responded better to Wave to Wake than the Samsung Galaxy S7. Go look at my reply. I said it was because of the IR sensors the Droid Turbo has. Maybe I should have gone into great detail and explained the S7 does NOT have those sensors, but I didn't.
So, in my 2nd and 3rd replies I had to explain.
The Moto Droid has IR (invisible light) emitters and sensors for motion the Galaxy S7 doesn't have.
The only reason I seem testy is because you asked a question, I gave the correct information. You countered with misinformation, which I had to correct.
I've owned three of these Quark phones for 3 years. I sold one and now own just two. I know the specs, I've written bootloader unlock and root guide on them, I've conversed with the devs about them. Your question was a simple one, I answered it, and you seemed to want to make it complex.

Thanks for the insightful comment. I really appreciate how you added to the conversation. I'm jealous i don't have your insight. You must be really dumb or really arrogant to offer such insight.
As i said, and I believe the other poster confirmed, the motion detection is based on light, as i suspected rather then proximity. Turns out it is IR light reflected back by the blaster. It is interesting and fully explains why the performance is so much better on this phone then others.

What part of "it has an additional IR detector/sensor" don't you understand?Yes IR is also a kind of light but you are confusing it with the regular light sensors present in every phone.
Now get this clearly 'Quark has an additional IR sensor which other phones do not have'.Every android phone has a light sensor which is the ambient light sensor but in the case of Quark it has an additional IR sensor.
Thanks for calling me dumb for no reason.It takes some next level dumbness to do that.
You are unbelievably naive.

Thanks for explained the difference between light on the visible spectrum vs IR light. I had no idea there was a difference and after the other poster replied I had no clue the wave to wake function was a result of the bouce-back of the IR blaster. Before you took the time out of your busy day to explain to me what i understand and don't understand I was basically lost in life.
Man, how did I live this long without you explaining stuff to me. I dunno man, you are pretty much a hero. Are you a teacher or something?

Just letting you know.

That was pretty weak. I mean “phone god” and “go f*ck yourself”? I don’t want to tell you how to do your job but if I can offer some constructive criticism and perhaps insight.
It was obvious from my initial post that I was not sure how the wave to wake function worked on the Droid Turbo. Chazz answered and because I often find his answers unnecessary snarky and bordering on gatekeeping for an outdated phone, I replied with an equally snarky response. That response was largely dependent on the dictionary definition of the word ambient and the fact that IR is light, just not on the visible spectrum. It would only take a cursory glance to see that as a very apparent and intentionally muddled response. Mostly because at times I can just kind of be a d*ck.
There was just so much to go with there. You could have called me out for being intentionally vague, you could have called me out for basically using dictionary definitions of common technical terms to muddy the issue, you could have called me out for being a d*ck. There really was just so much there to work with. Instead you went with “phone god”, “dumb”, “go f*ck yourself” and somehow attacking my command of the English language.
Come on man, this isn’t amateur night. You need to step up your game.

Do you make a hobby of calling other users things like "dumb" or "phone god"?
Perhaps you make a hobby of white knighting other poster by calling people who respond to them "dumb or arrogant". Despite my personal annoyance at Chazz's communication style, he has consistently shown himself to be more knowledge about this phone that anyone else who commonly answers questions here. I'm not sure if he needs your protecting but I will given you the benefit of the doubt and assume he appreciates it.
Once he responded to the question with the actual answer the functionality became clear and made perfect sense.
Wont the mods lock this thread already. Chazz answered my question with his replies.

Proximity sensor not working with always on display

Hi
I've been trawling through the forums for a couple days now to see if anyone has come up with a solution to, or a reason why Samsung doesn't leave the proximity sensor on while the always on display is active anymore (since the Note S10).
I know the sensor has been moved behind the screen. But it seems to function in the same way it used to. It still blanks the screen during a call, if I hold something over it up to about 20mm away. Just not with the always on display.
I'm currently using aodNotify as a sort of workaround. But would much prefer if the always on display just worked like every other damn phone!
Does anyone know the reason why Samsung has disabled this? Uses too much power? I Don't know.

Working in what way ? Mine works as in, it gets brighter or dimmer according to the light around me.....or are you wanting/expecting AOD to turn off when the screen is covered ?

Exactly, the former of what you said is all it* does when AOD is active.
In any case this is now normal operation possibly done to help save battery.
*I'm not sure that the proximity sensor is the ambient light detector?

I think what the OP is saying is that for example if you cover the screen whilst the AOD is on, it used to turn the AOD off before. It no longer does this.
Behavior started with the S10 series.

Interesting.

On most other phones, and Samsung's prior to the Note 10. If you put the phone face down, or placed it in your pocket, the always on display would turn off to save battery. They no longer do this.
I wonder if there's a work around for this somehow.

Question Galaxy Watch 4 classic using palm to turn off screen?

It's not working on mine - is this feature removed on GW4?

Just checked my watch 4 LTE 44mm and it goes dark when placing Palm on it for some second's...

I guess mine has a faulty sensor. Old Gear S3 worked fine with palm turning off the screen. Not a very big deal though...

You're not alone - it doesn't work on mine either. I concluded that Samsung removed it/it's not a Wear OS feature, as it wasn't in the setup tutorial, and there's no setting for it. Although I have seen others like galaxys claim that it works, I'm not convinced...

Depends if you're in a hurry or not

Works on mine, too. The obvious questions are:
A. Is your always on display setting activated?
B. If yes, does your watch face have a dimmed view?
If a is yes and b is no, then placing the palm on the watch won't cause a change even if the sensor works. I had that issue for a while with a watch maker face that didn't have a dimmed view.

What if a is no and b is sorta, as auto brightness is on? *Edit*: Just checked with auto brightness off, still doesn't work. Are you sure your screen isn't just timing out as you try this?

If a is no, then b is irrelevant. If AOD is off, then the palm gesture should turn off the screen, period. The fact that the screen goes a bit darker proves that the ambient light sensor works, sure, but I'm unsure if that's the only sensor that determines whether the palm was placed on the watch. Might be multiple sensors?
Just saw your edit. I will test it.
Edit 2 after testing: my screen timeout is 15 seconds - the palm gesture is maybe 1 second. So that's not it.

Interesting. Thought maybe it might be related to using AOD, but nope, doesn't work either. Your's the regular Watch 4 or the Classic?

I use this feature a lot it works perfectly on my gw4
For me it works in both the cases aod on and off... Difference being with aod on it dims the screen and with aod off it completely blacks out the screen
It also silences the call and stops the vibration when a call is received

Reset didn't do anything - other than show me how poor the backup is on the watch, and force me to install SHM Mod again... I doubt it's a faulty sensor (as everything else, i.e., auto brightness, works fine) - maybe my palms are too translucent?

Works on mine when bought new and then now. In between I had issues. After buying the watch I tested everything. Then about two days after my screen protector order arrived. PLaced it on the watch and I thought all was good. Eventually this topic came up in another forum and I checked mine. It wasn't working. Whatever I did it just seems that the palm to screen off wasn't working as it should. So I did a reset, etc. Still not working. I thought, who cares? It's not really a feature I use everyday anyway but somehow for me that means there was an issue. Then as I was looking at the screen I realized there were some lifts on the perimeter of the screen protector. I removed it. Then I tested the palm to screen off. Not once did it NOT work. I let it go without a protector for a day or so and it was still working. Since then I didn't use the tempered glass protector anymore. I bought one of those film type protectors and now the palm to screen off is working.

Thanks @thephantom for the hint! Apparently it's working on mine as well, I just needed to put my palm much closer to the watch screen (in comparison to my Gear S3 where it was enough to put palm over the watch and not touch it at all), I'm pretty sure it should work for others too on GSW4, once you press your palm against the watch (touching the bezel with your palm with light pressure ) - it was just wrong expectation on my side from the other model...

Well, I'll be damned - that does work. In fact, using the ball of your thumb seems to work well, and every time.
