[Q] cold temperature effects - Galaxy Note 8.0 (Tablet) Q&A, Help & Troubleshooti

just curious about something my note 8 did. it was in a cold environment around 25 degrees F. when I went to use it, the screen lit up but it was all jumbled up. After it warmed up for a couple minutes the screen came up normal. Just wondering if this is something that would be expected or could I have done some damage? it is working fine now but just want to make sure this does not screw me after the return date
has expired.
thanks

My primary concern about getting a device like this cold would be damage to the battery, lcd, and any condensation cause by bringing the device from a cold to warmer environment.
lcd's can typicaly withstand below zero conditions before having any issues so that probably wasn't a problem
It likely wasnt cold long enough to do any damage to the battery and I'm not confident that that temperature is low enough to have an effect on it anyway.
I would say if it seems to be running fine now then it's probably fine. But if it's going to have you concerned go ahead and exchange it. When I got my note2 the bezel had a slight creak to it and the glass didn't seem to be quite straight on close examination. It bothered me just enough to take it back to the store and trade it for a new one.

Screen cracked overnight. How?

My girlfriend owns this phone, and put it on her dresser overnight. In the morning she found it in the exact same position, but there was a crack going horizontal along the screen, causing the bottom half to not work.
How does a phone crack like that overnight without being touched?
She claims that when using this phone that it often gets extremely hot to the touch when plugged in. Maybe that has something to do with it?
I've read that it is some kind of defect caused by heating and cooling cycles. or it could be that the battery itself puffed up and cracked your screen.
This Gorrila Glass fibre has these dealbreaker issues, it mostly happens due to the following reason : Upon gaming and/or charging, the upper half may get extremely hot and the lower half remains normal and takes relatively more time compared to the upper half to change its temperature. This regional temperature difference when sufficiently high causes tension and it gets cracked. DO NOT keep the phone at cool surface when it gets hot, heat is NOT the culprit, but the temperature difference is. You may keep it on soft cloth or a relatively warm place in future.

Mineral water "bath" - will my phone evenutally die?

Yesterday my phone got spilled with sparking mineral water. I found it in sort of boot loop, realised what happened, pulled the battery, tried to dry it a bit, tried turning it on (not a good idea, I know now), then turned it off again and left it to dry with a fan. My phone sort of turned on then, only the screen was still a bit weird, shortly flashing from time to time from brown color to home screen. Anyway, today it seems to be OK. BUT I read now that any water that is not distiled water can cause corosion because of mineral content. Obvisouly my water had lots of mineral contents. So my phone is now just hanging by the thread before it dies? I am not about to go get it all wet now to wash it down with distiled water, alchol or one of those repair kits they are offering. I might just make things worse. Does this mean I better start shopping for Note 3?
Water just heavily increased the probability for your phone early retiring.
If say for healthy phone the time before 50% fault chance is 5 years of everyday service, you shortened it maybe as twice.
Yet it may be fully conditioned for next 10 years. Or be killed tomorrow from other reasons...
I'd start to collect money for the next device. But would never rush to buy it before the days of the current one are over. it's not a too long wait those days, you have plenty of sellers.
I always have near my old Motorola Atrix with a parallel SIM card. Helps me when I overplay to much with ROMs and kernels.
Well that sounds pretty encouraging in a way. Thanks!
I have a N1 which was in the washing machine for at least 20 Minutes back in 2009. The bluetooth chip was fried but everything else is still working.
If you wanne be sure that the problem is note getting bigger you have to make sure the phone is completely dry before using it. I'd turn it off, remove the backcover, put it in a rice bowl and let it sit in a warm and dry enviroment for a few days. Mineral water is one of the better things you can wash you're phone with .

Completely unresponsive touchscreen

Hello all,
I will preface this by saying that this issue is likely a result of water damage. However, my experience has been a bit odd. So someone bumped my chair, spilled water partially on my phone. I immediately removed the case and battery and let the phone sit for a good half hour before examining it. Looked completely dry so I inserted the battery and booted up. Went perfectly fine until the home screen appeared, at which point the screen did not register any touches and I could not interact with the phone. Removed the battery again and reexamined the phone: upon shaking it I found that some water shook free and was immediately worried. Let it dry for another half hour or so, rebooted it, and it worked perfectly for about half an hour, listened to music and such.
While texting, I noticed that there was some worrisome screen flickering going on so I removed the battery again and let it dry for another hour or two. Now I've reattempted to reboot it, but the screen absolutely refuses to respond to touch input. The phone appears to work perfectly fine and there is no damage to the screen I can see, nor does the flickering appear anymore. But touch input is fully unresponsive.
My current plan is to by a replacement digitizer, screen, and frame combo and replace that but I wanted to check in with the forum first to see if anyone has any ideas as to what the problem is and how I might go about verifying that the digitizer is indeed broken.

I've personally not known digitizers to go bad from a little water. Usually it's an internal area where the water is getting too. If you're no longer under warranty I'd take the phone apart from the back by taking out the screws and examining it that way. It may be too late for it if it's caused flickering in the screen. It could have weakened it. Am I saying don't buy a digitizer? No that's up to you. Unfortunately since you used it within a few hours of it getting wet I'm not sure. The best thing to do is to at least let it have a chance to dry overnight since the water gets in places that not much air gets to it takes longer to dry. Some have had luck putting the phone in a baggy of dry rice to extract the moisture. I've never had much luck with that method. I've always taken the phone apart as much as I can and then putting rubbing alcohol on the board to seep in where the water may have gotten and then letting it air dry. Make sure not to get it on the screen though. And with any advice like this I take no responsibility if the phone messes up, becomes unusable or turns into a Ferrari

Thanks a ton for the reply. I have essentially come to the same conclusion. It is quite an absurd issue that EVERYTHING appears to function, but the screen is no longer responsive to touch input. I'm going to try and replace the display body (only $50, can return it within 30 days if no luck). My Verizon contract ends in mid July so I just need a phone that can limp to that point or whenever the next Nexus is released.
Well, I managed to replace the screen/digitizer/body (essentially did a transplant of everything) and now my phone is back in reasonable working order. Had some odd issues with screen flickering again so that is worrisome, but the touch screen now works fine. Only issue is that the screen is absolute trash and is washed out, with major light leakage around the bezels (may have gotten some ****ty knockoff from China ).

Testing Samsung Galaxy Note 7 Water Resistence

So got my phone 2 days ago and finally decided to take my phone for a swim in my salt water pool. Everything was fine until I dipped my phone underwater for 2 seconds. Phone then started to malfunction like crazy! Power button stopped working, camera would randomly open every few seconds, google on tap would Activate every few seconds. I turned my phone on and off and let it dry for one hour and the phone was still acting crazy. Even while the phone was on the lock screen or on the always on display screen it would go crazy and turn the camera on! I was getting ready to return my phone the next day as defective. I then took the phone and dipped it in regular sink water for a few seconds and now it works fine! Does anyone know if this phone is only resistent to fresh water and not salt water?? Lesson learned, never put this phone near water again. Hope I dont experience permanent damage after only having the phone for a few days!
I am not surprised at the reaction that your phone went through. The only thing seperating your Note's innards and water are some rubber. Even though it's rated at IP68, it speaks nothing of it's ability to withstand what mother nature is capable of. But I recommend that you stop dipping your phone in water for no reason. Unless of course you have a YouTube channel to which I will say I am looking forward to hot nickel ball vs Note 7. I am a sucker for those.
I actually had gone to the lake yesterday and tested this out, of course after watching a youtube of someone else using the phone under water, and can't say that I've experienced any issues. Then again the lake is freshwater, but I'm interested in knowing more about the affects of saltwater on this phone... Probably because the charger port is still exposed?
The ports are sealed which means there shouldn't be water getting into the phone itself to mess with the internals. I don't think salt makes a difference except it might confuse the screen input.
The phone shouldn't be acting in this way if the seals are doing their job. If indeed there is water ingress, go to Samsung for an exchange.
Along those same lines of salt vs fresh water, what about hot vs cold/room temperature? Regular tap water from the sink, the pool, getting sprayed with the hose...all fine. But what about a jacuzzi, a natural hot spring or a hot steamy shower? I took mine in the shower yesterday, but at a lower temp than usual to test it out, it was warm water, and the phone did fine. Nervous to try a full blown hot shower or jacuzzi. Anyone have experience with it in hot water yet?

Interesting because my pool was also Heated and was probably 85 degrees. I wonder if the heat along with the salt water affected the phone. It's weird but once I dipped it in fresh water for a few second everything went back to normal. However, I really think it was the salt for some reason. Must have been something Electrical that made the phone go crazy!

I literally dipped in for no more than 5 seconds! I didnt even use it underwater. If the phone cannot withstand 5 seconds being submerged in water than it should not be IP68!

Judging by my warm shower (not sure the temp, but not nearly as hot as usual for myself) I wouldn't think your heated pool would be much different as far as temp goes. I would guess the salt probably had more to do with the erratic behavior and random inputs than the temperature of the heated pool.

My friend who has the Samsung Galaxy Edge 7 used his phone to take pictures underwater with his phone and didn't have any problems. That's another reason why I'm concerned.
Actually it is the salt waters fault...
Salt water is more conductive than freshwater due to the sodium and chlorine ions within it. This has probably meant the screen has freaked out as it works on conductivity etc.
Even after drying out there was probably a residual coating of salt on the screen and when you washed it in freshwater it was removed and it started being OK again.

Really interested about people testing the Note 7's water resistance.
This was one of the big selling points for the Note 7 for me, but from what I've seen with Galaxy S7 tests and Note 7 tests, it still seems like a risk using your phone in water. I think I'll wait until at least next year before testing out the water resistance. I'd like to get some use out of my new $950 phone before I intentionally submerge and it blows up or something.
Do NOT put the phone in saltwater. That IP68 certification is for freshwater. The saltwater was definitely the problem. I've heard Samsung will not cover the replacement if they find out it has been in saltwater.

Unless your friend has a salt water pool, or was in yours, I wouldn't be concerned about it. I would assume the ocean would have the same type of effect on the phone unfortunately. In regular water circumstances it should be fine, as I've experienced so far. I'm just curious about how the hotter end of the spectrum effects the phone.

Well seems we have our answers about salt water
salt water conducts electricity better than sweet water.
in fact, you should be fine dipping an open non-WR device in perfectly clean water as it doesn't conduct electricity at all(not easy to find)
water resistance with this phone refers to it's capability of keeping the water away from the internals, which it does well enough(i read somewhere the rating means at least 30 minutes at 1 meter depth)
your phone wasn't affected by water on the inside, but traces of highly conductive salt water on the screen's surface which mimicked tapping from your fingers.
you should definitely avoid "extreme" temperatures (freezing or hot water) as these will cause both the casing and the sealing material to change shape a bit which can create gaps.
and also avoid soap, as it weakens the water's surface tension allowing it to leak through smaller gaps.
I think Samsung should at the very least tell people not to use the phone in Salt Water in it's Ads!!! Alot of the answers in this thread make sense and it seems that it's not a good idea to use these Samsungs in salt water....
I went to the beach yesterday...i didnt even go in the water with the phone (too cold) when i was driving home I had a warning about my charge port having water.
Interesting.
Good info about no salt water... glad I didnt trat it the waves.....phew!
It's in the manual: no salt water, no washing with soap etc...

See this guy putting his note 7 into coca cola flor 11hours
Phone do it great

Your best bet is to treat this water resistance as a precaution. Yes, Samsung even uses shows the s7 series (includes the note) as being able to handle taking pictures underwater. I am sure this is the case, but the warranty for this phone VERY SPECIFICALLY says that if the water resistance fails, they are not responsible. There is even liquid damage indicators in the sim slot. So, again, this will be at your own risk.
Also, salt is more conductive, etc, as everyone has already said. What is more important, and an effect that can't be washed off with freshwater, is the corrosive nature of salt on electronics, and rubber. The salt, overtime, will eat away at a water sealing gasket. If any salt gets into the sealed portion of the phone....game over.
I owned a S7 for 2 weeks, before returning it and getting an s7 edge (I now have the note 7). I was talking on the phone when I got drenched by a drunk buddy with a hose. Guess what? The LDI did not trip, and there was no signs of water damage. The phone worked fine...but the mic never worked again, for the remaining week I owned the phone. I even told the store I returned it to, and they were nice enough to take the phone back anyway. But if the mic malfunction was the result of the water exposure, and I assume it is, Samsung would not have been obligated to fix it for free.
I take advantage of the water resistance, but I don't flirt with it either.
Now I'm nervous that I somehow did some permanent damage to my phone. Seems to be working fine right now with no issues whatsoever. Speaker seems to be working fine. Anyone know other possible permanent damage to the phone I should be on the lookout for to determine if I should return it during the warranty period?

Screen defective, white halo

Hi, since I got up this morning the screen of my Note 10.1 has a white halo on it.
Do you think it's a hardware fault? New screens sadly cost double what a used note 10.1 would cost, but maybe its just a loose connector?
Its flickering and getting worse the more contrast it has to display.
Anyone have seen something like this before
That must be a mechanical defect. Probably someone sat or laid in the Note. One of the two glass plates or the rear polarizer have been bent in a concave ir convex shape.
Can also be caused by excessive heat, like on the small lcd in my car dashboard, where a similar phenomenon has started to occur more and more often and in a more severe manner recently, caused by sun exposure and the car's heater and disapperaing when cooling down.
Or delamination of the gapless touchscreen. Now there is a gap on the outsides.
Thx for the reply. I have the tablet hanging on the wall, using it as an interface for my home assistant, so the screen is on pretty much 24/7.
Therefore i can't really imagine that there was too much pressure on the screen at any time and heating up could've maybe happened if it locked up during the night, but that hasn't really happend ever and in the morining it was running just normal, except for the screen. The sun can't really get to it either.
Well good thing is the problem fixed itself. The affected area started getting smaller and smaller and the effect also lessend over time. About 2-3 days it took.
Maybe there was some moisture inside it or something idk
Something had snapped or bent from and then back into shape.
I'd suggest that it was heat related, bootlooping while charging,probably.
I could trace such with the history of my battery monitor app(complete with temps and for as long as i set the the range), but the course graph of the system battery monitor could have have provided hints, too. But that's long gone now.
My very first Android device was a tablet, that once too many went into a bootloop. During charging AND during the time of the exploding Galaxy Notes. The whole surface (metal and glass) had the same temperature, no more hotspots, and was almost too hot to touch(50c at least).
I'm not sure whether the screen was discolored, there was only the small boot logo on black, but i immediately threw the thing into the bin outside, display still glowing in the dark.
This is really dangerous when the device is connected to the mains and the surroundings not fire resistant.
In the meantime the battery of my P605 started to blow up.
Middle of backside and even touchscreen are bent outwards.
But the display is still fine, though this kind of malfunction could happen to me later.
Will get a replacement battery. The original one from 2013 still has more than 50% capacity, but is much thicker now...
