Hello. I received my handset on Saturday morning from P4U and have been very impressed so far, especially compared to my experience with the One X last year where I had to swap 3 handsets before finding one without a major problem.
I have noticed however a possible glitch with the camera. When using the camera outside in bright sunlight I sometimes get glitches on the screen in the form of a jumping/rippling effect which is sometimes accompanied by a faint crackling/clicking notice. On one occasion it would not focus at all, with the screen rippling the whole time and refusing to focus. Following turning off and on again I have not had the problem to the same same degree, although it does happen occasionally with maybe just one of two ripples before the image on the screen settles down. The issue does not seem to arise in other scenarios (indoors, etc). Had I not had the situation where the camera could not focus at all I would just have put it down to the particular way that the camera focuses
Also I noticed that when the issue was most pronounced, I was standing outside our house in a bad/poor mobile reception area, just on fringe of out Wifi connection within the house. The phone was also set to auto update and was trying to do so. Could this therefore be some sort if interference issue interfering with the camera sensor or imaging chip?
Hs anyone else experienced anything similar? I am very pleased with the handset so if this is standard I would not exchange it. However if this is an indication that I have a dodgy camera module or imaging chip I would want to do something about it now.
Many thanks.
Just tried to use the camera to take photos at the theatre in combination of dark foreground and bright background. Camera struggled to focus on a number of occasions, with repeated clicking and pulsing/ripples on the screen as before. Never seen anything like it with a digital camera. Might be something to do with ultrapixel technology but it can't be right can it? Any ideas? Looks like an exchange may be necessary...
Reminds me of another thread...you should check out this thread : http://forum.xda-developers.com/showthread.php?t=2196059
Might be the same problem.
Thanks - I had seen that one too. Not the same effect, but I have seen that issue as well.
I called P4U today and got given a swap code to exchange the handset in-store, which I did earlier today. Not had a chance to test the new one, but hopefully it won't have the same issue as I have not seen anyone else complain about it before.

Do you have a video clip to show the ripple effect you have mention?
Official reply, an experiment and a possible solution about the "purple" camera
My HTC One 32G Unlocked from the official website takes photos covered with purple noises at night. I contacted HTC via their website and got the following reply.

They mentioned the temperature so I did an experiment about it. The photos are taken in Shanghai at 11pm. Night mode on so ISO800 locked.
(Ignore the coat-hanger at the bottom)
(#1) Taken immediately after cooling down for tens of minutes:

It's wonderful, although it's much brighter than the actual scene.
(#2) Taken after shooting for 2 minutes:
View attachment 2141410
Quite purple.
(#3) I put it under AC for 5 minutes and took this one:
View attachment 2141411
Recovered from the purple problem.
(#4) Under AC for 5 minutes, shot under normal light for 2 minutes and took this one:
View attachment 2141412
A bit purple. Not perceptible.
(#5) Under AC for 5 minutes, gamed (Need for Speed Most Wanted 2012) for 5 minutes, and took this one:
View attachment 2141414
Obviously purple, though better than the second one.
Just running CPU & GPU will also lead to that problem.
From these photos I conclude that the problem is caused by temperature. However, I can't bring a fridge when I'm going to take night shots!
The two heat sources are chips and camera itself under low light.
The heat from chips is relatively weak, and stopping playing games before taking night shots is feasible.
But what about the heat from the camera itself?
Interestingly, shooting under normal light won't significantly heat up the camera. (See photo #4) Therefore, modifying the software algorithm to force the camera working as normal under low light to prevent it from heated severely may be a solution.

Will check it today only!
My experience confirms your observations.
Low-light photos taken with a "cold" phone look good and present no purple tint issue. However, after using the phone for a while (taking photos, web browsing, playing, charging, whatever..............) it becomes warmer and low-light photo quality seems to degrade..........
mine take a purple pictures in low light every time .. after a intensive use and a long time not used ...
Bought the phone for the low light capability, but the result is worst than my wife bb bold. So disappointing.

On my One my photos are purple even if the phone it's cold :\ Next week I call the assistence and gonna replace my phone
EDIT : I cooled down my phone with a package of ice. After few minutes I launched the camera app and the problem still there. My sensor is screwed I guess.
I see this same problem with my m7spr version. I first noticed when it was laying flat on the table completely blocking the camera, and when turning on the camera app, there was a purple hue all around the screen prior to even taking a photo. So even with ZERO light you can see this purple
I'd have to say that your experiments may be (somewhat of) a coincidence. Did you leave the camera running while cooling down the phone and then try to take the picture?
This is a classic example of HTC trying to shrug off the issue. Your phone is defective. I had this problem, and it didn't matter when I took the pictures, or what I was doing beforehand. The issue seems to be caused only by higher ISOs (1600 and above). Leaving your ISO setting on "automatic" will obviously cause this issue in low-light. If you lock your ISO setting to a lower number, the discoloration is less noticeable.
I took my defective model back to the Sprint retail location and they did a warranty exchange for me. The replacement doesn't have the purple tint at all - no matter what temperature...
Since nougat update there is two things bugs me, I was hesitant to ask before but since no one come up with them;
- Some heavy load processes directed to only 3 cores, 4th one seems to be not loaded. Programs I tried and saw this behavior are CPUburn(loading cpu for test purposes) and Camera HDR+ shot processing(Google camera). I thought it might be hardware but other processes like browsing seems to utilizing 4th core so I suppose it might be some kind of energy save feature.(Battery optimization is off by the way). I did not tried developer preview, I hope it wasn't a known issue
- Google camera since 4.1 does not let you take HDR+ shots one after another, you need to wait until previous processing finished or nearly finished. I thought it might be encryption stuff but I tried Camera 3.2 and it lets you take 3 HDR+ shots before button gray out. Is everyone has this thing ?

Not loaded? Or turned off?
There are two things that could be happening when you are running heavy multi-processing software... 1) excessive heat WILL cause cores to slow down and eventually shut off. (2) keep a core clear for high priority events, like an incoming phone call.
Heat is not an issue, I disabled every thermal throttle besides core is online but probably like you say it is keeping one core clear for other stuff which wasn't the case in MM ?
Hello.
After a few months with my Exynos S21 Ultra, totally happy with it, yesterday I went to the beach for the first time to discover a terrible issue: if the phone gets warm, under the sun, the display dims down becoming unreadable.
I immediately thought about a problem in my device, trying to restart it several times, putting it in safe mode, checking every possible menu or submenu.
Nothing.
I moved to a bar, inside, and after a little while, everything went back to normal.
I tried to Google the issue and discover this is something "NORMAL" for Exynos phones (found a thread about the S20 Ultra):
if the phone heats, the screen enters a sort of "safe mode" dimming itself down to an unreadable point.
This means you can barely take pics because you see nothing in sunlight.
This is something new for me because nothing similar ever happened on my previous Note 10.
Anybody?

Not sure what anyone can do about this. This is not exclusive to the Exynos 2100, happens with the SD888 too (probably more often) and not just on the S21U, even the OP9Pro has similar thermal issues.
When overheated (either due to intense processor activity like Camera use, or external factors like ambient heat and sunlight) the phone will throttle down the CPU, close energy intensive processes like camera and dim down the screen among other things to minimize thermal damage.
It's not a pleasant experience, but it is what it is...

Does this happen with the iPhone?

I don't know.
iPhone can mean many different models, just like "android phone" can mean many different devices.
Not all Android phones have the above issue. This seems to be an inherent issue with the current architecture of both the E2100 and the SD888. They run hot, especially on the S21U and the OP9Pro. Once in a while we get chips with less than desirable thermal personality, just like the SD810 had in the past. If it's going to overheat, it will sacrifice performance and features to facilitate cooling down.
That's all I was trying to say in my post. I know you're not a new member here, so I'm presuming your question was more rhetorical than literal. If something I said ticked you off, it wasn't intentional - I was just pointing out the way things are with this generation of processors. And I don't think it's user rectifiable without crippling device performance.
If you have a solution to modify the E2100/SD888 thermal behaviour, please let us know, I'm sure a lot of grateful users would like a phone that doesn't heat up under heavy load.
My 2 day old, 5a with 5g just overheated. I have no case on it and it wasn't charging at the time. I was in a FBM video call and at about the 30 minute mark, I got the overheating warning. A few minutes later, the phone froze for about 60 seconds and then resumed. The phone was very hot to the touch! Ironically it was propped up against a laptop screen that was in hibernation mode and there is a table fan approximately 8 inches from the device blowing directly at it.
I reported it to Google Support and 1st level was very understanding. 2nd level told me to try some tips that he would send me because I was probably just overusing it. I told him I was using it exactly the same way I used my 2xl, but that didn't seem to make a difference.
I'll keep this updated as I continue to use my new "hot" phone.
Interesting. There's a known issue with recording 4K video, but this is the first time I've heard of an issue just streaming video.
Keep us updated for sure.
I have not tried the video recording at 4K...but I have been streaming YouTube videos and no overheating for me. YMMV
I have experienced the overheating issue while using video recording at 60 fps 4k. The phone didn't seem warm at all though so here's hoping it's just a software fix Google can implement.
If anyone can reliably reproduce the error, would you want to run some testing to see if the option for "Store videos efficiently
Use H.265/HEVC format" makes it better or worse?
I only had a heat issue when I first started my 5a, and it was installing all my apps in the background. Building the cache is notorious for its CPU use, so I can't say I'm surprised by overheating then. I've done a couple 5 minute 4k 60 videos without overheating since then.
I noticed the same thing today on my new Pixel 5a. Wasn't doing anything other than participating in a Whatsapp video call and browsing text messages.
I do have a Spigen case but the ambient temperature was low 70's inside.
This could be concerning...

I had a similar heat issue when setting up my phone the first time as well. It was when I was just going through the setup, and transferring everything from old phone to the new one. I, unlike you, have never experienced the heat build up, that occured with this phone, on any other phone in my many years of flashing ROMs and setting up phones (unless I was flashing it multiple times due to issues). So, this post does leave me a bit concerned....
I hope once I get my case that this doesn't start occurring for me.
I have experienced the video camera causing the over heating. It appears that any app using built in video recorder will produce the heat. Google camera, Duo, … Zoom. I did a little searching before checking here on xda.
Google admits that the issue is with the 60 bpf 4k recording that is the cause. And of course they do not have a fix available at this time.
I was hoping to find a way to lower the setting to 30 bpf but I cannot locate a way to change the setting. Can anyone help with that please? Or is it possible to install a different camera from the play store with custom video settings, and set that as default for all video?
Edit: I use the system wide dark mode, so I didn't see the camera drop down arrow which opens the settings popup. Open the camera, select video mode, touch the drop down arrow at the very top center of screen. The default setting for Frames/Sec is Auto. The other 2 options are 30 bfs and 60 bfs. Select 30 bfs. Touch outside the popup to dismiss.
I left the resolution at Full HD which is the default. Most users report the issue is while using 60 bfs at 4k.
My wife, who is traveling in another section of the country, also reports over heating. She was not actively using any app when the heating issue occurred. After rebooting the device she saw that the WebEx Meet app was attempting to connect in the background. A persistent silent notification was displayed in the notification tray. This app was one of many that she had transferred from her old device to her 5a during the initial setup process. I told her to uninstall that app. Then review all apps and remove any not needed. Probably should do the same as I have not looked at which of them may also be outdated and needlessly using system resources.
Grr, time for an update. I've had the overheat warnings every few days, but no noticeable effects from it. Until today!
I was in a long video call, maybe an hour or so and got the warning. Shortly after that, the phone shutdown. It was not charging at the time, battery was at 51%
I contacted support and they listened to my complaint and asked all the same questions as last time... except for the new question to confirm that I bought it from the US Google Store (I did of course, but not sure why they would ask that). They said a specialist will contact me via email within 2 days.
Having this issue as well. Shut down the phone for 10m and still got the issue when I powered on.
Crazy
I had a 5a for about 2 wks. I was in Facebook video chat for about 15min when overheated and dropped internet connection. I was holding phone in hand parked in car 80 degree day. I had one day left to return it, so I rma'd it. No way to report hardware problem as reason for return. Charged me $35 restocking fee. I loved the phone, but they need to solve this. If they fix it, I may buy again.
The phone overheating at all is unacceptable. I've never even personally seen/felt a phone "overheat". That's crazy.
Obviously some kind of defect that google will ignore for 1 year as per protocol.
I've only had my 5a 3 days so far but mine has yet to overheat. And I'm a heavy user. Now my OnePlus n10 after the android 11 update would overheat multiple times a day, sometimes when just sending a text. When it was on Android 10 it never overheated.
Im starting to have those issues too. I cant record for more than 1 minute sometimes
Was this solved in the new update? I havent updated due to root, so just wondering.
Thanks

No, I still can't record for over about 30 seconds to a minute
Unfortunately no... I'm still getting the overheating after the update.
This happened to me initially, like one user mentioned, when I got the phone and it was building the cache. More recently this happened to me while on a Caribbean vacation to Anguilla; was using the phone for pictures outside. It never got hot enough for a general overheat error, just always warning me that the camera was too hot and flash was disabled, or at one point camera was too hot when I was taking video and said the video could be unstable. I was filming in 1080/60. Switched to 1080/30 and it was ok. I have a Spigen Tough Armor case, so I wasn't surprised at that.
UPDATE: The phone finally died. I had been receiving the overheating issue about once a week since the beginning. Google support didn't care. Now, while I'm travelling in a foreign country, the phone died.
I called support and they said as a 1 time deal, they will replace it free of charge. However they only ship to the US and I have to send back this one in 14 days. That is an issue because mail from here takes months sometimes to reach the states. I"m not due back in the states until this summer.
WORST part: the password safe app that I use on my phone unlocks with my fingerprint. Never requires the actual password, so SHAME ON ME, I forgot that password. I have the password app on my laptop and it has current info, but I can't access it because I don't remember the actual password. :-(
PSA: use your actual password from time to time to ensure you don't forget key passwords!
