Is this thing supposed to get burning hot?

Like, even just using it as a phone, it heats up. Is this normal?

I get the same thing, it gets really really really hot. When I use it as gps, or go online especially.

yeah, its normal. never heard of it not happening

I cooked breakfast on mine this morning.

I put mine in my pocket... made myself sterile.

I've got a Fuze and it was white hot too. I took it back after about a week and just got a replacement. This new one is not heating up. Although now the problem I have with this one is the 3G connection is not as strong as it was before AND google maps doesn't work for sh!t!! I'm looking for a fix.

Sounds like your 3G isn't really connecting, make sure you try all the forum posts on enabling and forcing 3G/HSDPA connections. Whenever I run mine on 3G it becomes a nice little hand warmer. Force it down to GPRS and it's not hot and has a useless data connection (but good for when the battery is almost dead).

Normal? Extreme heat in an electronic device is normal? I don't think so. If any device you have is getting warm enough to be of concern TAKE IT BACK AND EXCHANGE IT!
BTW - mine doesn't get hot. I can feel warmth if it's charging, for instance, but I wouldn't call it hot.

Pretty much yes they do especially when using heavy power draining functions ie: Wifi, GPS, etc.
Some of the claims here of cooking breakfast, becoming sterile maybe slightly over the top and I have never been actually burnt by the device. But I have yet to use a HTC device that did not get hot when using the above functions for a period of time.
Just my experience and I certainly would not be using one if it boiled my nuts.

It´s not normal for a electonic device to become that hot, some heat is normal but not EXTREME HEAT!
Try flashing another radio and see if that helps, if not then you should send it back for repair!

mmmm, ever put something made of plastic near the heat exhaust vent on your laptop?? Most modern electronic devices that are based on a CPU generate exteme heat that is why they have cooling, heat sinks, etc.
I'm certainly not going to get into an argument about this but the bottom line here is that they do generate certain levels of heat. It definately should not be enough to burn you though.

Yes but a laptop has X amount more power then a phone! And you know, if the laptop didnt have a FAN to cool it down it would not last you even a few minutes!
However, our phones are designed without fans and are not supposed to get EXTREMLY HOT!
Let´s face it, no electronic device should get extremly hot, if it does then something is wrong, or something will be wrong with it soon!

Mine gets warm, but never hot even when using the GPS or wifi for over an hour. During a 20 minute telephone conversation it will get warm, but again not hot.

after 20 min of phone call, connected to wifi, on ac adapter, it got warm, never hot.

the hottest mine got was looking at vid porn via SkyFire browser. It looked really great... but oh man... the phone was sizzlin'.

Well I don't know if my phone is getting warm or hot. It's not an unpleasant warmth, just odd.
And Skyfire? I thought Opera Mobile was the preferred browser of choice.

My phone doesn't get extremely hot, mildly warm while surfing net over 3G, but that is it.

This is absolutely not normal and is one of the reasons i returned mine and went back to my Treo. I've used lots of high end phones and this is the first and only one that just starts toasting by itself when doing simple stuff.
Strange thing is that everyone i know with a T.P complains about the same thing. I could be watching Youtube for less than 5 mins and it starts boiling..what gives. I Youtube on my Treo (via Coreplayer) and it never gets hot.
I'd say this is a problem or issue with most of all T.Pro's. Sad really, such decent hardware specs.

I've also been experiencing heat coming from the back of the device, but only when I hold calls over around 15 minutes or if I'm using the internet extensively. I also notice it can create a good amount of heat when it charges. Usually when electronic devices have excessive heat it's due to a build up of dust.

So what am I to think? I have a few guys telling me NO! And the rest of you saying "It's normal" and ONE guy saying he exchanged his in and his new one DOES NOT GET HOT AT ALL!!!

Accel. Auto-Unlock for Dialer

Hello,
Since it seems like no one has ever asked this question before I've decided to post about it.
On the Droid when you dial a phone number and put the phone up to your ear it locks the phone's screen. Then if you are dealing with a PBX or menu system on the phone that requires you to press a certain option and you move the phone away from your ear to tap the dialer, the screen automatically auto-unlocks. This is, by far, the best feature I have seen in a phone to-date.
Where do I get a dialer that supports that feature (it obviously uses the accelerometer)? Somehow I doubt you can just rip the APK out of the Droid image and have it work on a G1. Or does that feature just not work on the G1 for some reason?
Any replies are appreciated.

The Droid uses a proximity sensor to tell when it goes up to your ear:

The Motorola Droid also has a proximity sensor so that the screen shuts off when you hold the phone close to your face. This helps to conserve battery life while at the same time prevent accidental screen input if your cheeks press upon the screen.

Not sure how you would do the same thing with the Accel.

That feature actually uses the proximity sensor, which the G1 unfortunately lacks.

Not sure why it would be so hard. Accel can tell how it's positioned and the position next to your ear is completely different from that of holding your phone in front of you. It would just require some evaluation and data recording of degrees and ranges.

Not sure about that. If I remember correctly the accell only sees if the phone is in landscape or portrait orientation, and when you are talking on the phone it is almost straight up and down. Not sideways. Will venture to find an answer.
Edit: You almost have to have the phone on its side for the accel to see that you have moved your phone. Don't know about you but when I talk on the phone it is almost up and down.

That certainly can't be since many games, namely Armageddon Squadron (flying game) use the X and Y axis on the phone (roll vs pitch). Also think of rolling objects in games that you have to "steer."

That may be true. I don't have any games on my phone that use the accel. I can only go by logcat durring screen orientation. I am sure you can now, the only problem is at what amout of tilt does the screen lock. And you would have to tie it in to when there is a call connected. Would hate for my sreen to auto lock when I am laying in bed playing with my phone.

Well, of course it's connected to the dialer - that's its only purpose. If the dialer doesn't have foreground then it won't auto-lock.
If developing for Android wasn't such a pain in the ass (compared to C++) and I knew more Java classes/methods then I'd probably just implement this myself. I'll probably get the myTouch Slide soon enough though.

We wouldn't be able to so much measure the exact position to do this but a good shake-like-hell-to-unlock-dialpad event might be possible... If I (or someone) can find some code for a dialer, I'd be happy to take a stab at making it "native..." I know just enough Java/Android to cause some trouble, so it could only be good ;-) If not the dialer, then an app could be started as a service, with an intent to snag the call, and listen for a good jostling. I wonder what this would do to the battery/performance and how often I would have to make it poll the sensor? Hmm....
I'll see if I can poke around and find ANYTHING. Haven't googlified anything yet... I do need something constructive to add to my workload.
And yes, the accelerometer measures force applied to the X, Y and Z axis. you can technically program it to sense when you've dropped (or are dropping) the phone.

I'm not sure if shaking my phone is really much better than tapping the screen twice - both require similar times for completion.

Here's a tar.gz of the source-code that was released with the Droid https://android.git.kernel.org/?p=p...9af2e10e23c7c21f22abec5f3d7fa05d6406a2;sf=tgz

Not sure if it's still out and compatible with the newest builds, but the app Shake Awake did this quite some time ago.

I used to use this on android 1.1. iirc it stopped working on cupcake, and I haven't checked on it since then.

I don't think this would work, because what if you're laying down with the phone? I'm pretty sure it would mess up with the Accel. I'm not too much into this, but when playing a game like teeter for example, the side of your phone has to be horizontal with..the horizon (correct me if I'm wrong)

Dialer wake-up w/o real sensor
Shake Awake never worked too well for me.
I have always wondered in the back of my non-programmer brain if one who was really good could implement a sonar/feedback type code whereby when the phone was close to an ear, the amount of feedback from the earpiece to the mouthpiece was quite low, but drawn away from the ear increased just enough for the phone to pass through to the code through an intent (is there anything like a feedback intent? I bet Meltus would know!), which would issue the commands to unlock and wake-up.
More ideally would be a program which got the earpiece to put out a search tone up around 20 kHz, which would be analyzed by the mouthpiece. Sound present = user has moved the phone away from the ear, wake up and unlock to touchpad, sound muffled or totally gone = user is still using the earpiece, don't unlock.
BTW, all 2.1 eclair ROMs I've used in the past 3 months have a setting for a substantial improvement to screen awake times during calls.

How much pressure can a screen take? Can I rest my head on it?

Not as weird as it may seem
At night I listen to music/radio while I go to sleep. I use a cheap phone at the moment but was thinking about getting a 2012 Nexus 7 that I can use for this (and actually use it as a tablet as well)
Will it be okay if it's under my pillows or will the weight/pressure damage the screen?
Thanks in advance :good:

Lol your tablet will be fine haha unless you're head is the size of 3 watermelons and weighs 50 pounds then but seriously it won't cause any problems

the question is more about how much damage will the mobile make to your head if the wifi/cell network is running trough your head all night?
except you run radio by earphone receiver with airplane mode on..then never mind

I use a quality speakerpillow, it has a long enough lead that I don't risk the phone/tablet and I can rest directly on the speaker and keep volume low and not disturb my partner.

Ha ha... That is really a funny question. But it should be answered. It won't damage your phone unless you move the pillow below your head above your tablet. Use a good cushioned pillow though.
And yes, do turn the airplane mode on. Radiations are not good for your brain. (I'm not expecting more such questions :laugh Just kidding brother.
Ohhh God. Why are we discussing about it? Doesn't it come with Gorilla Glass?

Probably you will have to worry not tossing the phone down to the floor while you sleep.

why you just don't do that and but your phone beside your below

Just buy a quality pillow speaker , then you dont have to worry about getting tangled up in headphones cables aswell

I really wouldn't worry about it for clarifications sake and a technical answer to your questions your main concerns would come from the stress your head would apply to your phones screen. More particularly the relation between the compressive force your head creates and the maximum compressive strength of the material in question before failure of that material under load. (Stress= F/A) The Nexus 7 uses Corning Gorilla Glass which has a maximum compressive strength of 800 MPa. That's 224,808.944 pound-forces per meter^2 and your head does not exert anywhere near that number.
Like I said you really have nothing to worry about you won't damage your screen by laying it under your pillow.

I'm surprised no one brought up the very real possibility of overheating. Sure, you can rest your head on it - but you're smothering it under a pillow and not allowing for the heat it will generate to dissipate.
It would be especially bad if you were charging at the same time - and either way not something I'd recommend anyone do. Why shorten the lifespan of your device by exposure to high internal temperatures if there are other options (like using it with a pillow speaker instead).

Or you could get a wireless headset?

Cranberry juice

What would happen to my phone if I completely submerged it in cranberry juice? I'm trying to pass a Chem class and the professor wants me to do something impressive with my phone since he sees me on it all the time. I showed him Cyanogenmod and the like but he's not fazed. He's like, 75 and doesn't understand computers. I don't know about the electrical capacitance of berry juice so I was wondering if I put my myTouch 4G Slide in a clear bucket of cranberry juice whether or not it would still be on while in the juice.

Have you seen their latest of wanting to take android away from Google? Do they not realize that if Google stopped pushing code to aosp they would die off completely. Then adding in untested code that causes tons of issues, forcing some of their developers to close source their apps so they can make money off of it. Yeah they deserve it. To the point that main aosp based roms have stopped using their sources and are ditching their theme manager.

Whatever battery you make I recommend using a diode connected transistor or some kind of a limiter to limit current to your phone so you don't burn it out incase you make some awesome kind of a bad ass battery.
That will impress your professor.
Tips:
You can make a fruit battery out of:
Four lemons (the bigger and juicier the better)
Four pennies
Five zinc-galvanized nails
Five sets of alligator clips
but I'm not sure if the mA would be enough to charge your phone but it will be enough to power a small LED.

Yeah, I wasn't thinking of a fruit battery, more like an old school voltaic pile made out of coins (like pennies) or metal disks from the hardware store. Depending on which metals and electrolyte you use, you should get 0.5V to 1V per "cell". The diode transistor is a super good idea, and you probably will need a voltmeter to determine how many volts your battery is producing and you should also be able to determine the mAmp being produced. Look at the specs of your the charger for your device and just make sure you don't go over the current or voltage specs. My guess is that you will not be able to generate enough current to fully charge your device, so I would leave it off and just try and get the "battery charging" display to light up for a bit. If you go down this route, be prepared to answer some "chemistry" teacher type questions. The more you know the more impressed your teacher will be.

Well if you have voltmeter you can set up your pile and try different electorlytes. Typically the stronger the acid and saltier it is the better. So you can try salt water, distilled vinegar, and salt added to distilled vinegar as your electrolytes and record the voltage/cell for each electrolyte...make a nice table, build your (probably 5V battery) explaining how the table helped you choose what kind to build, make a pretty picture displaying the chemistry involved and badda bing...you are done

If so, onions and proper leads can give you an eye-wateringly bigger jolt than citrus fruits... :crying:

That's a great idea. I don't have a working camera so I can't take pictures of the process to show you guys...

Question [Pixel 6a] Is this a hardware defect? [crashing when it's cold outside]

Hi everyone!
Just purchased a P6a during Black Friday. In general I am quite happy with the device and would want to keep it.
However, I have massive issues with crashes/freezes/reboots when using the camera.
I know that many people have reported similar issues, but my case is somewhat special in that it only happens on weekends. During the work week, I use the camera normally, and there has not been a single crash.
But when I go hiking/mountaineering/trailrunning on the weekends, I have massive problems.
I would say, every five photos I take, something goes wrong.
Sometimes I get a complete freeze in the camera app and have to do a hard reboot.
Sometimes, the phone simply reboots itself.
Sometimes it switched itself off.
Sometimes, the camera app seems to work correctly, but then a few minutes later the phone reboots all by itself.
Sometimes, these crashes result in broken, unreadable JPG photos on my phone.
This has happened up to ten times on each of my outdoor tours. I have observed this now over three weekends, on four different tours. After such a crash/freeze/reboot, the phone seems to work completely normally again, as long as I do not use the camera app. As soon as I use the camera app again, it does not take long until the problem reappears. But only as long as I am outdoors for extended periods of time. Indoors never any issue.
The natural suspicion is that it must have something to do with the temperatures outside. But temperatures here in late autumn Bavaria have not even been all that cold; the problems already occur at relatively moderate temperatures of a few degrees above freezing.
Software is fully updated, of course.
Because of the 100% clear correlation with outdoor activities of a certain minimum length, which I can only interpret as temperature dependency, I guess this must be a hardware defect, and I should ask Amazon for a replacement. But what do you guys think? What would you do? Is there any diagnostics I can do first?
Thanks a lot!

Locked bootloader still? Are you planning to unlock, or open to it? I would recommend doing so and doing a complete clean flash of the latest stock to both slots. Sometimes OTA's arent as complete as we like to think.
If you dont want to unlock the bootloader then I would at least do a factory reset, if you already havent.

Have you done anything to rule out everything else? Like are you positive that it's because of the temperature?
Maybe it's got something to do with cellular connectivity or GPS?
You could try removing your SIM/entering Airplane mode, and/or turning GPS off, and going outside, see if the issue persists?

Thanks for the responses!
No, I am currently not planning to unlock the bootloader. (Maybe I will, once the phone is 2 years old and the implied warranty has expired, but not now.)
Yes, I could do a factory reset. Is there a good non-unlocked way to backup everything I have already setup and configured?
No, I have no way of being completely sure that it is the temperature. Your idea that it might be linked to GPS is an interesting one. After all, I had the geotagging feature of the camera app enabled. I switched this off now, let's see if the problem occurs again.
Problem is, I can only test it on weekends. Being outdoors for only an hour or so has never been enough to trigger the problem. It had to be a longer stay outdoors of a few hours at least, and that I can only do on weekends.

Pretty sure that you can just flash the stock ROM, re-lock bootloader, and they won't know/bat an eye.

Could you leave your phone outside for a few hours? Instead of going on a hike?
From what I've gathered from OP and your reply above is that your phone starts acting up if it's been out in the cold for a while and you open the camera app. You might wanna leave it in the cold for a bit, wait for it to cool down to ambient temperatures, then try to open the camera app? If it still acts up, then we can be more certain that it's got nothing to do with geolocation, but with the cold temperature.

Good idea! I'll try that tonight and put it on my balcony for a few hours.

I suppose it could also be the fact that it get's moved/shaken more when I am moving on my outdoor tours...

Or maybe changes in altitude? Although, I don't know if you're that hardcore at hiking or not
Anyway, leaving it on your balcony could help narrow down the source of the issue.

I don't think it is changes in altitude, because one of the tours was just a trailrun in only hilly terrain with maybe only 200 meters of altitude difference between highest and lowest point, and even on that tour I had massive issues.

Do you keep your device in your pocket? If so, it wouldn't be able to get too cold.

When running, it is in a mesh pocket of my running vest, so it would get quite cold. On mountain tours it is usually in an outside pocket of my pants. So yes, close to my body, but still some isolating layers away from my body.
Other question, now that we are talking shaking as a possible cause:
When you shake your phone in front of your ear, with the camera module facing towards your ear, do you hear something? I can definitely hear something shaking, as if a tiny metal part is loose inside the phone.

I keep my bootloader locked. Each month when there is an update I unlock the bootloader and update the phone in case something goes wrong. Once I've successfully updated my phone I relock the bootloader which just requires a reboot. Unlocking and relocking the bootloader does not delete data.

Yup. Super faintly.
When having a camera app open, it definitely sounds like what you were describing. My best guess would be the OIS trying its best to keep everything stabilized.

Does it void warranty though? Like what's Google's warranty policy here? Does unlocking the bootloader once void it already?

No, I don't mean the OIS sound. I can also hear that one (very very faintly) when the camera app is open and I move the phone. (Sounds like a tiny tiny motor whirring a little.)
But the little clattering that I mean can be heard always, even when the screen is off. Sounds like a tiny screw is loose or something. It is also clearly audible, not nearly as faint as the OIS whirring.

No, it's not like you are flashing a custom ROM (which I'm pretty sure doesn't void the warranty in the US or Europe). It just allows you to flash a full ROM, not just an OTA. Google has provided this functionality. There is not warning when unlocking that this will void the warranty.

When I shake my phone "front to back," I hear that. Only when the camera app isn't open though. When I open it, I cannot replicate the sound.

Interesting. That seems to be a third sound. Yes, I also have that one, and just as in your case it goes away when the camera app is open.
But the sound I mean is independent of the camera app, and also occurs when shaking the phone side-to-side.

OK, the test results are in:
On Tuesday, I left the phone out in the cold on my balcony for 2,5 hours, and yes, afterwards the problems did occur.
On Wednesday, I used the phone indoors, no issues. A new camera app update was installed, I hoped this might be the fix.
But no: On Thursday, I again put the phone outdoors for 2,5h. The problems are back.
I will ask Amazon for a replacement.
Thanks a lot for your suggestions!

That's so strange!
I'd love to know what actually triggered this odd issue.
I mean, yeah, surely, something to do with cold temperatures, but that in itself doesn't explain a lot, does it?
I hope your replacement device won't have any issues!
