[Q] Tablet heating?

Hi I had purchased a Galaxy Note 10.1 recently and have been playing around with it. A concern I had was that on the upper left backside of the device, below the silver plate on the white surface, the device feels warm compared to other areas of the tablet when using any apps. Is this normal or not?

that is close to the cpu same on mine

Hi erica, how long have you had your tablet? Has it ever really bothered you too?

"Feeling warm" is normal for anything with a modern CPU inside it. If you put your hand directly on the CPU (or the heatsink covering it) in a desktop or laptop computer you may burn your hand since it can reach huge temperatures of 60 degrees plus.
This review shows the Galaxy Note 10.1 to reach 45.9 C on one corner of the back when under maximum load:
The Samsung Galaxy Note 10.1 had no issues regarding temperature. Even after long periods of full utilization during our stress test, the Galaxy Note did not become excessively warm. While the upper left corner exhibited slight hot spots on both the front and back side with temperatures of 45.9 degrees Celsius (115.6 degrees Fahrenheit), this temperature is still rather trivial considering the fact that our test was conducted on a hot summer day. During daily use, the surface temperatures of the tablet remained comfortably cool and under 33 degrees Celsius (91 degrees Fahrenheit) at every measurement location. The internal components showed no risk of overheating in any case and even the AC adapter barely warmed up.

Since it's plastic, that'll never feel "hot", just warm.
You should rarely reach maximum load if you use well-behaved apps, though some games will tax it a bit. It's actually pretty amazing what processor power can be achieved in this thing without getting too hot or requiring a fan, thanks to the ARM architecture.

So if the tablet reaches 52 C, thats alright? I really don't know specifics like this at all but would a tablet such as the asus tf700 feel the same way? I mean heat wise on a everyday medium load?

They actually get considerably warm being they are made out of aluminum. I had the tf201 and 700. It's not too hot though but you notice it

I am using system tuner to see the cpu temperature and I am getting high as 55 C. So I am in the green right? What is the highest the temperature can be and my tablet can still have a good lifespan?

A few things:
1. When I pointed out the review of this device that said it got to 45.9 degrees, that's the surface of the outside of the case. That's different to the CPU temperature, which will invariably be hotter.
2. Tools that report CPU temperature are invariably misleading. There are so many different ways to measure it that mean different things and sensors can be calibrated differently on different devices. I'd say leave it up to the engineers that built the tablet and trust that they built it to tolerate any heat it generates, which they will have had to.
3. Aluminium of the TF201 won't be getting warmer because it's aluminium, it'll just *feel* warmer because it's aluminium - even if it were the same temperature. It conducts heat to your body more efficiently as a metal. As a result, the case itself will actually help cool the tablet better, but don't go assuming this makes aluminium cases better - the engineers would have accounted for this in their thermal design, and we're not talking about all that much heat here anyway.
At any rate, this tablet doesn't get hot enough to worry about - far, far from it. The amount of warmth you feel is normal and in a tablet like this will never get close to approaching the heat required to reduce the CPU's life (unless something goes terribly wrong or you put it in an oven or something). It's not even worth worrying about. I'd worry more than in 3-5 years' time the battery capacity will have deteriorated to the point where it'll give you noticeably less battery life - because that will happen. If you're going to worry about overheating, worry about your laptop instead. If its little fan stops, is blocked or fills with dust, it is actually *quite likely* to overheat the CPU eventually - not that you're likely to notice, as the CPU will just throttle down.

Waterproofing verification

Opening this thread I would like to focus your attention about the waterproofing of our devices. Now seems to be a common problem, have gaps on the glass of the phone. Some see thin glimmers of light coming from the gaps, more or less accentuated. Logically, we must remember that the front panel is glued, and as we all know the glue that is used is transparent, so if the front glass is not perfectly centered, it is "normal" to see the thin light. I hope I do not say bull****.
The waterproof? I invite you all to take a test looking at CPU-Z reading the pressure / barometer.
With all the flaps closed, placing weight on the screen, I noticed an increase in value. Moments later, with the weight still on the phone, the value tends to return to the original, before the weight. Try it yourself and let me know.
bye bye

On people posting they saw light at edges of screen I checked mine and on left side I have a tiny amount of light coming through.
My phone was previously submerged in water with no ill effects.

who ever started this whole "pressure test" using the sensor is pretty clueless and i find the it nothing more than a bunch of bull for testing for waterproofing. all it really takes is an extremely small entry to get water inside.. even if you try to do this "pressure test" it will obviously increase as the sensor is extremely sensitive to pressure changes, this in fact still doesn't verify the unit is air tight because air pressure is constantly changing.
it's kind of like air pressure inside a car tire... the pressure changes depending on many factors. air temperature, road temperature, tire temperature, etc. the same with the internal phone barometer sensor.. i will have a hard time believing there is anyone out there that has done this "pressure test" and monitored it over several hours to see if it remained the same.. simply impossible, even if the device is technically waterproof..

it seems you do not understand the physics involved.
If there is only the slightest point of entry the pressure will note rise as there is no closed system.

It is not a matter of being confused. clarify once and for all the question of pressure, using the ideal gas law (who has studied physics will agree with me).
The ideal gas law says that: P * V = n * R * T
P = pressure
V = Volume of air inside the phone, in this case
n = number of moles of air
R = constant
T = temperature
If explicit pressure (the one that interests us), we obtain:
P = (n * R * T) / V
At this point, we expand P. As we know, the pressure is the force exerted on the area. then:
F / A = P = (n * R * T) / V (1)
In our case we have:
A is a constant
R is a constant
n is a constant
T is the only value that can vary, but for our thinking, we can consider it constant.
Let us now consider V.
V is a constant if the air is the same and does not change the volume inside the phone, if the phone is airtight. In fact, considering the equation (1), increasing F ('m pressing on the display), the equation to remain true, P must increase. If the force remains constant at a given value, P must remain constant to the new value. That's why in the thread I asked you if you happen exactly during the test.
Otherwise, if V has the ability to change (the air inside the device is no longer constant because it has the ability to get in and out), then increasing F, P remains constant because V decreases (air comes out from the device). It happens when we keep the flaps open.
The question for us is: If you press on the display, and maintaining a constant force (let us help with a small weight of an object, instead of pressing with your fingers), the pressure stabilizes at a higher value? or, after rising, returns to its original value? In the first case, airtight. In the second case, well, the assumptions are two: the phone is not airtight ... or maybe it is, and somehow Sony has found a way to make a device that is waterproof but still manages to keep "ventilated "CPU, GPU, RAM, etc. ... components that produce heat.
Insisting that are only hypotheses, more people carry out this test, we will have a more clear idea of the whole.
So, dear friend, I am not confused. Bye

So are you telling me that, the pressure , after I put a weight on the screen, goes to an highter value and stay on it until a remove the weight? Does your z3 do that? My z3, after I put a weight on it, pressure goes to an highter value but some instants later go back to the original value (without weight). And when I remove the weight, pressure decrease from the original value, and then, returns to the value before all of this.
In other words, maths words:
Pressure without nothing on the z3: X
Pressure with a weight on it: X+2
1 second later pressure go to the value : X
If I remove the weight, pressure: X-2
1 second later....: x

I just rechecked, it's as you observed. After reliefing manual force pressure goes below starting pressure and then quickly returns to "X"
I guess it is because of the sensor Logics/design because such sudden pressure changes are not normally occurring and thus confuse the readings

Ok but, when you initially give a force on the screen, the pressure go to an higher value, ok... and then quickly go to "X", isn't it? And then happens what you write above.
I honestly do not know if I give you right or wrong about the algorithm used for the pressure sensor. Mathematically speaking, looking at the equation I wrote above, the pressure should remain constant and higher if we are going to put a force on the glass. But it does not happen and both me and you get the same behavior. We just have to wait and collect more test by users ... and if someone will tell us that the pressure is kept constant at an higher value, the answer is already given us

I have a z2 with a cracked screen and a vulnerable flap as I've already had water inside. I just received my new z3. Pressure tests on each device result in the same exact results. They are exactly as you describe. In my opinion the pressure test proves nothing.

Then why DON'T you do the test and post the accurate results don't have somebody that dies not have a clue ruined his phone if he does are you going to replaced it of course not

Same here, ~820hPa without pressure then goes up to ~823hPa and comes back to ~820... After removing the weight it goes to 817 and then back to 820. Something is wrong with this method I think. Oh by the way, my screen is completely centered but I do see light leaking on the left/bottom side while on full brightness and in a completely dark room. I'm really worried that my phone won't be waterproof because of that leakage and I'd love to know whether it is or it is not...

Tested on my device and I got the results I wanted, short increase and then back to the correct pressure when placing a weight on the screen.
Isn’t it quite obvious that the pressure first increase a bit and go back to the correct reading?
If it didn’t the construction would be incorrect, having a barometric pressure sensor that didn’t react on the outside air pressure, what would be the use of that?
The barometric sensor is in the phones to give us better height reading, as the accuracy of GPS height wise is rather bad, so it MUST react on the outside air pressure.
There is a big difference between airtight and watertight, and there are many materials constructed that keep the water out but let the air in, you can’t test them with a barometer either.
The topic of this thread is incorrect and makes no sense at all.

Try comparing the results when the flaps are fully closed, and the flaps are opened.

I just did - 890 without pressure, flaps closed and 893 with pressure but when I openedbthe flap it stayed at 890 no matter how hard I pressed so I'm guessing it is air/water tight.

Disppointed with the Barometer/Altimeter App

I am very disappointed with the Samsung Barometer/Altimeter app, The barometer only registers in whole inches of mercury. All watches I had in the past, register in hundredths of inches of mercury. I wonder who else feels the same and would like Samsung to fix this error or maybe a developer could create a replacement app.
Edit: They finally updated the app and it shows the barometric pressure in 100th of a inch of mercury. Big thumbs up

I agree. Hopefully Samsung does address it. Meanwhile I found a free app called "FBarometer." Just search/install via Gear app. Seems pretty accurate, doesn't register in hundredths but does do tenths so a step up from wholes inches at least.

I have a feeling Samsung rushed to get this watch out (obviously, everythings backordered now it seems).
I have a feeling there will be many updates in the near future. At least I hope so.

If you touch the barometer to display the trend look at the outside ring, the barometric pressure is displayed gauge style with a red dash marking the pressure and the units are to the hundreds place. It's still not great but you can at least tell the difference between 28.5 and 29.

I live 77m above sea level and my watch shows -97m, a bit out me thinks.

Barometer and altimeter are useless. I live between - 90 and plus 154 meters, in Amsterdam which is - 3. Consequently also the floor counter is facked up.

You can use another very good app called Barometer & Altimeter. I use it when go mountain. I talked to author this app before download it. It was tested by a few climbers and created with help mathematicians and physicists. The measurement error is < 1%. It is better than my stock altimeter GPS-based. Very good app, absolutely worth buying.

I totally agree! Looks like the sensors that Samsung has choosen are totally pieces of crap.
Altimeter: from my sofa 5m... couple of hours later 35m!!!
Barometer and heart rates are also giving vera random figures compare to 'real' hardware.
Samsung just wanted to show more features and be in line with competition but it does not work.
They better should have left very useful features that were present on previous model likre IR Remote that I had on my Gear 2 Neo!
I will never understand Samsung when they decide to replace features in place of add new features. Mainly when they remove very useful and working gears and replace those with unreliable sensors....

You do realise that the altimeter is air pressure based right?
If the air pressure has changed during the two hours you were on the sofa then the altimeter will show a different reading.
That's the whole point of calibrating it before you set of on a climb or whatever you're up to.

Yes it's barometric. And altitude jumps all over the place even when the pressure is constant. Eg walking up the stairs, 2 stories, results in a climb of -12 to +30 meters, should be - 3 to +4. And my daily run which is totally flat at - 3 shows 116 meter hills. It's true and authentic crap and I'm gonna replace for the Fenix 5 as soon as possible!

Thats why shealth thinks i climbed 10 flights of stairs while just walking about for nine hours.

To those who think that their Gear S3 sensors are any accurate, just try to disconnect your phone Position/GPS or to use the gear S3 alone. You will then see the truth about those very inaccurate sensors that Samsung has put in the Gear!
They are only 'providing' you with accurate figures when position/gps on your phone is on, in other words, the 'accurate' info you are seeing are provided by internet data, and not by the sensors themselves... Shame on Samsung for that!

i have the same issue. at 155 ft above sea level, but watch states between -150 and +435
it also only counts 1/10th of floors climbed

I don't get accurate floor counts but I know for a fact the gps works well without my phone. At least the golf app I use gives me accurate readings in standalone mode.

Same here. I stood outside under a clear sky around 30m above sea level. Tried calibrating thrice but each time it says -7M.

Skydiving
I have used the S3 Frontier when I skydive along with my Viso II Digital Altimeter and they are within 25-50ft of each other. This is without the phone. It is actually pretty accurate. I do not use the built in app. I use one from the store called Skydiver Altimeter. It works great.

Well no clue about others.. but just got mine and comparing with two others one ming Suunto and its like some others pretty darn accurate. Just going up a few feet.. was spot on. I wonder if like the phone you need to reset it at now and again.

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.
Click to expand...

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]

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

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.

Roger roger captian.. Keep up the good fight. I'm done with this conversation. Have a good night. Look up the definition of ambient.

You are either really arrogant or really dumb.When someone gives you an answer try to check the validity of that information before blindly countering it with 'wrong' or 'useless' or 'not applicable to the situation' info.

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?
I am so naive I shouldn't I even be allowed to use a phone.
The last thing I will say before i go back to work is, I am grateful to just have someone so abso-****ign-lutly amazing, insightful and generally awesome comment in this thread.

I am sorry God of smartphones and science.I shouldn't have talked to you like that.My apologies.
And about that abso-****-ing lutely sh**.Go f**k yourselves.I bet you will be so good at that.

Okay god.And btw this is a global forum which means that you need to interact in english.So first lose your ****ing arrogance and learn proper english.Your english is making me sick.
It's a shame actually.But I bet it will be easy for you since you are a god.
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.

*double post, sorry about that.

Okay man. Just tell me something, is this some kind of a hobby of yours? Starting a post just for abusing members who spend time to clear your doubts?

Not at all.
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.
(thank you Chazz)

Question Screen burn

Can using the galaxy watch 4 for prolonged periods with very bright active screen or AOD (as in some of the Watchmaker app) cause screen burn? Thanks. Sorry bad English.

The brighter it is, the faster it degrades.
I avoid using them in direct sunlight or over 50% brightness except very briefly.
After 2 years of heavy usage my N10+ show no signs of degradation. Blue pixels are the first to fail generally. Red the last. Green is the wavelength the human eye is most sensitive to.

My Samsung Gear S3 Classic was used with AOD about 9 hours a day, every day, for 3 years without any "burn in" problem. I don't know why the GW4 would have any problem doing at least the same. Some reports of it being damaged in just days were most likely due to some very bad manufacturing/part defect, not due to a design limitation.

There are several people that reported burn in and even the people who say that it is only faulty devices dont dare to use the screen on max brightness + AOD...
I would not risk it!

AOD is probably safe if the tap on feature is available.
Direct sunlight and AMOLED displays are a very bad combination. I would wear it on the underside of the wrist or covered by a sleeve when in the sun.
It's got some cool features but when out and about especially working out, the electronics go dark. They are a distraction that can only cause harm.
In the real world life altering updates happen in a split second*. No second chances.
Many "kids" don't understand this; they will learn or burn.
*Multitasking is a myth in most cases. Only people at an expert level are capable of this, with certain tasks/situations and only after many months or years of training and practice.
It becomes a hardwired skill only then.
Don't delude yourself... you may only get one chance to react appropriately in a fraction of a second. Not easy to do even in ideal conditions.
Relax your guard only in low threat level environments.

Okay. Thanks everyone. I think better to be careful
