I've had the camera shut down due to overheating after only a couple of minutes of normal use, but have also been able to record 4K for 17 minutes (then I pressed stop, because I couldn't imagine myself ever recording more).
[Xperia Z2 General] griffin_1:
That's not great =/ The 4k camera, even though is not good, i understand because of the hw and other phones limit the time of 4k.

Excessive heat on other things are not good. My s3 does overheat but it doesn't seem to be something as excessive as the z2 but i would like to upgrade to something that doesn't heat as much as my s3 that can get hot just by using it after while with something like taptalk and a bit of yourube.

That's a bit strage. Maybe it was due to the weather, if its warmer or colder. Still, im seeing it depends a lot of yout weather condition, the phone production and just not using the camera to much, which limits the phone.

Then there is also the problem that extreme overheat can affect other usage/apps other than camera.

Thanks for your replies!
[Xperia Z2 General] CarlBlomqvist:
The 17 minute recording was actually made just a couple of minutes after the app closing from overheating from fiddling around!

Also, I think the overheating is purely related to the camera app usage. I don't think stressing the CPU/GPU will cause overheating at all. Unless you overclock of course.
[Xperia Z2 General] ipmanwck:
I have a new one less than a week and camera app closes especially in sunny weather :( sony are hopefully working on a fix
[Xperia Z2 General] Tachikoma_kun:
I was in Spain last week and managed to take 12 photos in total which were all within an hour of each other. The rest of the time I would open the camera app and the phone would freeze, the camera was out of focus and touching anything caused the phone to hang. Only way to recover was to lock and unlock the phone then close the camera from the multitasking button.

Also, the USB port cover metal warped in the heat so the centre bent outwards, breaking the seal and eventually falling open.

Really disappointed.
[Xperia Z2 General] gm007:
True the freezing just happened to my phone too,i can open the cam but the display is out of focus and no buttons work. I will repair the phone with pc companion maybe it will fix this issue.
[Xperia Z2 General] ipmanwck:
Is the answer really an S5 :( sad as it maybe at least Samsung make bomb proof phones. I can't believe I am about to say this but I think Samsung are the new Apple! Just churning out lacklustre designs over and over but they jus work.
[Xperia Z2 General] One Twelve:
Less than a week ?

Thought you'd be at the two week mark by now.

you got another 5 months more to put up with it :D
[Xperia Z2 General] ipmanwck:
Ha ha. I am willing to compromise.. At present just so darn hot in UK so camera is closing loads. I would never get an S5 but maybe in September I will change it up. Hoping for a fix soon as taking some amazing shots with this phone. Today phone was boiling whist watching a movie and couldn't open camera at all ((( lets see what sony do. Just seems odd this is heating up sooo much when other flagships don't. Must be glass / metal causing issues? now I appreciate plastic. Ha ha.
[Xperia Z2 General] One Twelve:
Since the Z, the Z2 will be the 5th iteration of the same design. I think they've got the design down pat. Earlier models did not have these same heating issues.

The thinking is something is up with the cpu. The others use the AC version, Z2 uses the AB version.

Irony is AC runs at 2.5Ghz whereas AB runs at 2.3Ghz. It's actually slower but for some reason heats up more.

If the phone was boiling watching a movie ? was it using SW rendering or HW. The former is more taxing of the CPU and consequently battery. Course if you don't have the right codec installed then software is the only option.
[Xperia Z2 General] Envious_Data:
The Z2 cpu is right next to the camera, it causes very bad heat

Also the fw is messed up, 4.4.2 is kinda buggy and there is some loop processs causing unnceccisary load within the xperia framework
[Xperia Z2 General] AlanDS:
Forget about videos. I get shutdown message while taking photos also.. Cannot take more than 5 photos at outdoor. I reside in Kuwait which has very hot weather during summer. So this phone camera is of no use for me.. I have to wait till winter.
[Xperia Z2 General] ipmanwck:
Running videos on mx player SW. Have all codes installed. I think I heard this version of Android is buggy so maybe it's the operating system. Wish Google would maybe work on it as ios and windows can run on very low tech hardware and perform much better. Look at the 1020 and doesn't break a sweat. They actually recorded a pro music video using them which is just amazing --- Ellie Goulding - How Long Will I Love You: http://youtu.be/an4ySOlsUMY don't get me wrong I love my Z2 but If MS get the 930 running android apps then that would be impressive! Nokia make amazing cameras.

Maybe phoneblocks is the way forward) just think a massive camera dominating the back of the phone with no compromise ;)

Next year I think will be a great year for tech. This year is a Deffo dull year for progression in mobile tech. 4k video and 2k screens running on outdated chips and so called prime versions is just businesses cashing in.
[Xperia Z2 General] danhatcher:
Let's not lose our track here. I read through this thread late last night and I know that this thread is all about camera overheating problems (the thread title gives it away) but with all these numbers and all this expertise, shouldn't we be trying to work towards our own fixes with the WIDER overheating issue? The original posts in this thread were very interesting, looking at the internals and hardware stats - trying to find the real root of the problem and trying to find batches that may have been more faulty than others. It's all very well saying that you can get 'x' amount of time out of the camera but it seems irrelevant when you can only get that out of competitors' devices, software limitations or not. As many have mentioned previously, this is new technology and the processors probably aren't quite ready for it.

I'm about to make my next two-year commitment to a phone. My GS3 has served me well but it can get really hot through just general use in the - albeit relatively mild - UK summer. There probably isn't going to be a period in these next two years where I can pay a lump sum for a new device so I need to make the right choice now. I need to know, for example, if the Z2 is going to overheat when I try to complete something quite intensive like restoring on Titanium Backup. I'm also unlikely to ever be filming in 4k but if there is something I can do like undervolting the CPU to fix these issues then that's more progress than just testing the camera over and over (what was Einstein's definition of insanity?), but I apologise because I understand that is what this thread is meant to be about.

If Sony continue on a 6 month cycle then it's unlikely they're going to fix it now that we're about halfway through this one. However, if they continue with the 6 month cycle then at the end of these next 24 months we could be looking at a Z6 device, coming up to a Z7. What more could we have then over the 2.3Ghz CPU and 3GB of memory that we have now? What is the REAL solution to this problem? Just a bigger heatpipe?

I feel like I'm starting to forget my point (forgive me, I just woke up) but, basically, as XDA members we should be working together towards a widespread fix and not just sounding like a broken record. We're the smart people - forget about your Average Joe.

I apologise.
[Xperia Z2 General] One Twelve:
ios is a less than hd screen running present gen cpu. Simple trick that means it heats up less and peforms the best in games.

if you can get an android phone with a similar configuration then you have similar performance. It's called the Z1c or G flex. For me, too small and too big. Unfortunately, no further choice beyond those.

Can you mention how it performs with HW encoding, does not heat up as much or the same ?

It's 2:38 minutes long. Has lots of edits of people wearing sweaters instead of tees. Must have been cold when they did this recording.

You mean to tell me its not possible to do this with the Z2 ?

nope, it will be much more expensive than what sells now and will have bulkier design. if you want things sleek then there are compromises to put up with.

aka galaxy K zoom, something i'm wrestling with because it has zoom and proper OIS but comes in midrange package, weighs more too.

proper OIS means you can get low light without camera shake but is useless if the subject also moves in low light. For that there is a zenon flash.
[Xperia Z2 General] tototony12:
sad

I don't have it
[Xperia Z2 General] ipmanwck:
I have a solution for you which I used today. It was my son's sports day (3 years old) and here in the UK today the weather is scorching. We took a picnic with us and whilst I was using the video camera I felt the back at the top start heating up so to cool it down I held the phone against one of those ice packs you take on picnics in a cool bag to keep your food / drinks refrigerated. This worked for me as I no longer use a case due to the heat build up.

So here is one solution or alternatively instead of taking a picnic everytime you leave the house take a small icepack. I was thinking about an icecube but that would just be too silly.
[Xperia Z2 General] Envious_Data:
I have also have a solution

If you take them thermal drink cup things that keep your juice cold or hot , it works well because my Z2 fits in mine and i usualy keep water,

Its only a few CM under the surface so Z2 has been fine when i left it there for about 30 mins
[Xperia Z2 General] ipmanwck:
Nice.
[Xperia Z2 General] danhatcher:
My first reaction when reading this thread was, "Isn't the phone waterproof? Just take our for a swim when it gets hot." But it has been pointed out that this could shatter the back and/or front glass from the rapid change in temperature. I wouldn't want to be taking that risk on an almost daily basis.
[Xperia Z2 General] jonmorris:
7What fun and games...

And tomorrow and Friday are due to be even hotter days!

And, yes, the last two screen grabs were taken a different day. I have more!
[Xperia Z2 General] ipmanwck:
Tell me about it buddy. Love the camera hate the issues. Only keeping phone short term and coming up to colder times so will jump ship later in the year or next year.

Sony should really do a press release and also should be ashamed.
[Xperia Z2 General] jonmorris:
Sony has said it has a fix to improve things but when is it coming? I've had about my fifth day of grief trying to take photos out. I'm in London again tomorrow and then Legoland on Friday, and it's also set to hit almost 30 degrees (and in the sun it will be a lot more, I'm sure). Clearly I'm going on have loads more of these problems.
[Xperia Z2 General] ipmanwck:
But Sony have not admitted any fault with design / hardware. I don't even think they are accepting the fault is down to them and are only stating that it's due to 4k being so power hungry but it's the camera use at any time has this issue not just 4k. I would like to see watchdog address this and then I am sure Sony would change their statement of a firmware fix will help. Lol. Better heat dispersal and the chip being relocated would be a good answer. Maybe even an internal fan like on a pc. That would be awesome. Have to be tiny though. May make the phone into a little boat with a small engine.
[Xperia Z2 General] One Twelve:
Stamina mode not help ?
[Xperia Z2 General] jonmorris:
Sony had said it had found a problem with the camera in general, not just 4K (which should perhaps have a 5 minute limit like the competition).

I do think the hardware plays a part, especially dissipating the heat, but it's also got to be software if Sony claims to have a fix in the works. Let's wait and see if it really does fix the problem.
[Xperia Z2 General] raseel256:
I downloded #cpu monitor micro# from the store and notice the cpu speed while recording 4k .the 4 cpus cores increased work .that may cause increase in tempriture.

What about if we go to setting >apps >all >overheat control then disabling the "show notification" ? will that work? or may harm the device? I think we will never suffer from the overheating message and solve the problem.
[Xperia Z2 General] danhatcher:
It would put the device at great risk. It is at risk in its current state.

On a similar note, is there anything you might be able to change in Tasker (or similar)? I don't have the device so I can't test myself.

I personally like the small boat idea.
[Xperia Z2 General] ipmanwck:
It's odd. I thought it did but other day no? Before I used battery saver and stamina and that may have helped.
[Xperia Z2 General] gm007:
Sony need to change the developers.
[Xperia Z2 General] One Twelve:
What if you switch off for five minutes let it cool down and start again.

I've heard from people in India that the phone heats up but it also cools down fast. For reference, 30 degrees c is the norm here, not a warm day like you're temporarily experiencing. We try to have 25 degrees c room temperature indoors which i think would be ten degrees lower for you.

What is the week number of your phone ?

Since you're on your second unit chances of assembly defects are low. You acknowledged that there was a difference between the first one you had and the present one i thought.
[Xperia Z2 General] danhatcher:
Alright, alright. No need to brag :P
[Xperia Z2 General] Sensination:
I have tested my Xperia camera (14W25) thouroughly and these are the results I got:

*

4K - overheated after over 13 minutes of continous recording to external memory card (considering the fact that other flagships limit 4K video recording to 5 minutes (HTC & Samsung) I must say I'm pretty impressed)

*

1080p - I gave up after 20 minutes of continuous recording as I got bored. I don't think I will ever need more than that anyway.

*

AR - same as above

*

Other camera options 15 or 20 minutes plus

*

The ambient temperature was 25 Celsius and after each test I allowed the phone to cool down for 10 minutes without using it.

*

In line with my tests*I think that anyone who has overheating issues should return their phone for replacement as they must have a faulty unit. *I guess I must have a really lucky unit. In my opinion Sony fixed overheating issue at some point but decided to keep quiet about it. The manufacture date of my Xperia is 14W25.

*

If I were you guys I would start returnig your phones for replacements. In case anyone from Sony tells you that the phone is not capable of recording for so long, give me a shout! I'm more than happy to send you a proof.

*

Sony needs to take responsibility!
[Xperia Z2 General] feis:
No one said its not capable, i have w16 and can record 4k for 10minutes+, you missing the point:D
[Xperia Z2 General] One Twelve:
haha, hot day in england is worse, your dwellings are designed to keep heat in :(

You can see the indian user thread is very active yet i do not see any in here complaining. Puzzling. if anything they should have been jumping up and down in this thread given the higher average ambient temperatures.

is there a heating issue here or not, some say there is others not.
[Xperia Z2 General] ipmanwck:
Yes this unit is slightly better. I may try and change this one as only had it since end of June so will see if the online store I got it from will allow me or if I have to send it to sony? At least if it goes to sony they will maybe do a proper repair?? who am I kidding. I wonder what sony have done to improve this issue with newer devices?? Anyone have a good answer?
[Xperia Z2 General] xxlikquidxx:
A solution I have found when I encounter an error message about phone is being too hot to use the camera, is to use a third party camera app. It works great. The app I used is Camera Zoom FX.
[Xperia Z2 General] Tachikoma_kun:
Yeah I noticed this on holiday when I couldn't use the Sony or Google camera, I could still take photos with BitCam. Not that it did me any good mind... I don't think I tried Camera Zoom FX, but have it installed so might give it a try on the weekend.

[Xperia Z2 General] jonmorris:
I'm in Windsor today, at Legoland. Hottest day of year and maybe even for 10 or 20 years. My Z2 has been virtually unusable all day. Running red hot (with battery drain to suit) and camera won't even start until I run the phone under a tap for a while.

But, if it's any consolation my LG G3 also stopped working and said it would shut down to protect it from damage.

Next time I take a normal camera!
[Xperia Z2 General] adamtg:
Yesterday I was outside for half a day and it's quite hot and sunny over here (Germany about 30 degrees Celsius) so I had to use my phone on full screen brightness and my phone was hitting 50 degree Celsius (battery temperature). It was uncomfortable to use. Inside it doesn't go below 40. So I can take few pictures and the camera shots down! I really like this phone but the over heating issue is so frustrating!
[Xperia Z2 General] jonmorris:
Back home, and it's still 24 degrees outside - with thunder just starting for another storm (hopefully cooling things down a bit).

What a horrible day. Z2 was a nightmare. Hot all the time, needing me to charge it up half way through the day even though it hadn't done anything, and this wasn't because of something running in the background - just the heat. The phone can't handle the heat!

And the G3 was just as bad.

My wife had no problems with her Z1 Compact though, which was surprising as when I used it I remember having camera issues - but that was some updates ago.

I hope the Z3 fixes the heat problem, even if everything else stays about the same. We're supposed to have a fair few weeks of hot weather, so am I to assume my Z2 is not going to be usable until the autumn now?!

Since I updated my i9505 3 months ago. Instagram is causing serious battery problems to my phone. I've already tried to things that may solve that like, uninstall the App, clear cache, update the App to the latest version, but nothing worked. The only thing that appears to do some effect is forcing close the App. But as soon as the App gets back to run in the background, the drain starts again. Instagram in draining 60% of my battery. Much more than the screen and the Android Os. Please, anyone who had this was able to fix this?

[Moto X Q&A] ryanzurlo88:
I noticed this yesterday on 5/1/14 has anybody else have this issue. And do I contact Motorola or Verizon over this issue. The phone is not even a week old.

Edit: this is throughout the whole phone. I just looked up white on Google images to get the best example and added the arrows in to show my issue
[Moto X Q&A] carlz28:
Take it back to Verizon. Less than a week old, they'll have to give you a brand new one. Expect to do a full factory reset as they 'may' think an app is causing it. Probably just standard practice on their part though. But things like this are generally hardware related so I'd say you have a defective device.
[Moto X Q&A] ryanzurlo88:
Thank you for the response. But I contacted Motorola themselves since it's their product. Manufacturer warranty. They will have a new one out to me in two days.

I am planning on getting my wife and I each an MDA from Amazon and I had a couple of questions first.

1) Has anyone gotten the MDA with T-mo USA service from Amazon? How was the process and cust service?

2) They make you get the $30/month/line data plan, but I have read on some forums that I might be able to "trick" them once I have the phone and might be able to go down to the $20/month/line Blackberry plan or the $6/month/line T-moWeb plan. Has anyone tried this? We will use a combination of WiFi and GPRS for both web-surfing and IM'ing. Will both of these work with any of these plans?

Hello all . so i have a s2 i9100 android version 4.1.2 .iwant to flash an old verion of ice cream sandwith 4.0...

the problem is that i tried this before but when i did, the phone will stay at the samsung logo like it is loading but nothing happen

can you help me please

Thank you
[Galaxy S II Q&A, Help & Troubleshooting] MistahBungle:
Personally, I would stay away from Android 4.0x, if you flash, root your phone & do a factory reset, the brickbug comes into play (4.0.4). There has also been one or two people who didn't even root their phones (allegedly) who bricked them doing a factory reset on 4.0.4.

If you must flash 4.0x, use 4.0.2/4.0.3 (I still wouldn't even do that). If you have problems with the flash, for example, bootloop - boot into recovery & do a factory reset. If that doesn't fix it, find Hopper8's 'Odin troubleshooting' thread stickied in General, download the 3 part firmware linked in the thread, and flash that with Odin (this will wipe your phone).

If you still can't get a successful flash, it might be something else fairly simple as is often the case with these, try everything in Hopper's thread. I'd be surprised if you can get a successful flash with the info in his thread, it's 'the Bible' for these things.
[Galaxy S II Q&A, Help & Troubleshooting] Gokulbalram:
I'm sorry, but did you flash it via Recovery or via Odin? If you did it via Recovery, you'll have to flash back to the official Samsung firmware (The ICS one obviously).
