strange dotted line

i do have a strange dotted line at the bottom of my screen, which seems to get larger slowly.
The dotted line is shown when the device is turned on/off.
It's not in the glass, but below the glass.
I wonder if anyone has seen this before.
i tried to make an image of it.

I have it too, not sure what caused it though!

No issue here.

The touchscreen is lifting from the tft, to which it's glued, causing air bubbles in the glue, IMO.

Me too although it doesn't bother me since it doesn't do anything to the viewing experience.

All, thank you for your replies.
I contacted Samsung support, and they informed me that it was no known issue on their devices.
If i want to have it repaired; i could sent it to Dynafix who does the repairs in my area, and they will check if it's a fabrication fault or an user fault.
I have sent the picuture to dynafix to see if they could say me something about it, though i am not sure if they will do this.
I will keep you updated.

Ouch, dynafix..... You usually get your device back in a condition worse than when it was when sent in.

Me too
I also have those at various points along the bottom. They don't bother me enough to risk sending the tablet in for service.

Maybe answer is that; however,the seller said that these dots are originated from the people that scratch or something when i see these dots on the Screen of tablets at showroom of Samsung. But i think there is a problem. After a while i think all note 2014 will be like that. I examined all of them in different stores. Guess what. All of them has that issue.

I think you should bring your tablets to be fixed.
Also , i have a question for everyone who has that issue, are your galaxy notes 10.1 black or white ? I saw this issue only on black ones' screens. Are you using your tablets in fully brightness? Because i realized that it begins warming rapidly and more at bottom of the screen which is so close to the dotted place.

Is your tablet black or white? Do you use it when it is charged, frequently? Almost how long have you been using your tablet?

Brightness setting is in the middle. Yes I use it alot everyday for work. The screen is mostly always on and I charge it mid day in the office and still use it while charging. Sometimes the screen gets warm when being used and charged at the same time. Been using this tablet since November

Tnx for your replies,
I bought it in january. no dots observed yet. I also have black model. I dont use in charge. I use it portable way when it is not charging. I am so angry with samsung because of that issue. They had made really big mistake and they dont accept their faulty. They even dont try to fix this issue for next generations.

At first I was bothered by it.. but now not so much. Good thing the dots are on the bottom of the screen and you wont notice it when using the tablet. Yes still samsung should fix this issue

Mine is black.
I have used it while it was charging but not very often.
I purchased it new about 7 weeks ago.

I had the exact same issue with my first note I bought in November. Ended up returning it to the retailer about 6 weeks into use and buying a new one I've had for about 6 weeks so far as well. No issue on the 2nd one as far as I can tell right now but this seems like another common problem.

If these bubbles/dots are caused by the reasons i mentioned earlier, they align with the colored rim of the touchscreen, because the color layer increases thickness of the glass by some nanometers. Going towards the center of the screen, the gap narrows because of adhesive force bending the glass. This should prevent the bubbles/dots from wandering inwards. Otherwise there's a huge issue with the device, though mine is (still) fine.

I noticed these dots on my white note after I got it back from battery repair. Not sure if it was there but I have 3 clusters of bubbles now

since yesterday i've this strange line as well. It came out of nowhere. After reading this tread @yararli could be right about something. Normally I use my screen about 25% brightness. Yesterday I watched a episode at almost 100% brightness. So there could be a causality between the brightness en warming-up which result in this strange line. My tablet is black bought it around december.
Is there any news about returns? Will there repair this problem or give a new tablet?

Some Heating issues with Oneplus 3.

Even though most posts claim that OP3 is quite efficient with heat management and everything, i found some issues with device :-
1 ) Phone heats up during Dash Charge, heating is more during the 0 - 60 % phase then its reduces.
2) Heats up while shooting a 4K video.
3) Sometimes Heats up even with the use of apps like Insta,youtube ,fb (If you multitask them together).(Try downloading a large
file, buffer a video and do some light task....i guess the phone heats up with extensive use of wifi and multitasking).
4) Handles games likes OK3 , NOVA 3, Asphalt 8 very well, But somehow heats up while playing Mortal Kombat X
All this based on my experience with using the phone for quite sometime now. Please let me know if these issues are common to all or i should contact the Oneplus Support?

I get the exact same thing and I have heard that this is normal
Sent from my ONEPLUS A3003 using Tapatalk

In all those scenarios, heat is not only normal, but expected.
There are dedicated cameras that can't record more than 10 minutes of 4k without overheating and turning off. No need to worry.

exact thing happens to me!!

Duuh, your phones heat need to go somewhere, especially with a metal case you will feel it a little bit more then with a plastic case. Nothing to worry about heating is normal for every electronic device. Don't see what the issues are here.

I think that problem is that op3 deals with heat quite good while, say, playing asphalt or sth but can heat up while using messenger with all apps closed.
I'd say that it might be problem with drivers.. But idk

Yup, bro I agree with you, but is it normal for the phone to become warm near the earpiece during call?

Near the earpiece or the whole back of the camera, I'm not a specialist but it shouldn't deliver problems. It's normal that everything above your volume button heats up more then the rest of your device, since the Soc is there.

Your phone will heat when you use it :laugh:

Help! constant reboots and very fast battery drain even when completely stock

I just washed my watch with tap water to clean it up. but after i dried it up, the watch keeps rebooting every few minutes and becomes quite warm.
I even restored it back to lollipop but same thing happens. also uninstalled all 3rd party apps from my phone.
did washing it cause the problem? i read here somewhere that they even dive their watch on a swimming pool with no problems.
please help me troubleshoot this. I won't be able to send this to a service center since I work in a remote location. :crying::crying:

i don't know if it helps but I got mine back to normal again.
first, I just let it sit in the sun for about 30 minutes with its face down. do not put the lcd up facing the sun.
the watch will heat up obviously so let it cool down for a while.
after that, my watch started to last longer.

Heart Rate sensor during training mode

I have problem with the HRM on my watch. The HR measuring is working well in rest mode, but when I start a training, the sensor measures my HR, but after 1 minute it stops working, and no HR data on my watch. The green leds are flashing, but no HR data. Anybody has the same issue? Or my watch is defected?

Did you follow the manual on how to wear the watch? There is a section for that. Placing the watch at the right place help the monitor to work more appropriately.
Sent from my SM-N960F using Tapatalk

I did a 2 hours hike today and after 50 minutes I had to remove the watch and wipe my wrist and the back of the watch to make the HR monitor work again. So to me it looks like it has a problem with sweat/humidity. This is a huge problem IMO, enough to return an almost perfect smartwatch.

Galaxy Watch uses optical heart rate monitor. These are pretty good & easy to use while measuring rest heart rate.
If there is moisture (water, sweat) between your wrist and the sensor, readings will be probably off or cannot be measured.
Because of this, these sensors are pretty useless at intesive training, where you get sweaty.
These are not really sport clocks. You can read more by googling "optical heart rate monitor"

It works well for me while playing soccer, so I detest the theory that this does not work while being sweaty

maybe you dont sweat much ? I lose more than 1 liter of water in 90 minutes while training.

It works great for me when I'm swimming tho.
I have to tighten it down before jumping in the pool, but I have not had any issues while submerged in water.

will give it a try Tuesday and will report back. Thanks for the advice.

same issue here. after 5min running the heart rate just shows -- sometimes it comes back after few minutes, but very unstable...

Hello
i found out that this happens when the heat rate hits exactly 100bpm and again at 160bpm. at that time the heart rate cannot be detected. very reproducible!
it has definitely nothing to do with sweating, moving or anything else.
once the heart rate gets a bit higher or lower than it comes back.
you can check that out by using the heat rate app in continuous mode or just use the app headset rate graphic and see what happens at 100 and 160bpm.
can somebody else confirm that?

went for another 2 hours hike and I had to wipe the back of the watch 3 times to "reset" the HR monitor. This is not acceptable IMO so Ill probably just return it.

I've had two Galaxy Watches and they exhibit the same behavior. If I move the watch further away from my wrist it helps a bit. It seems that it has issues during high intensity training where it'll just blank out for a bit. Overall it's still pretty decent and not enough to make me want to return the watch.

happened last while... sitting watching TV. I had a flatline every time I manually activate the HR monitor. Only a reboot could bring it back to life.
Many threads about this problem here: https://us.community.samsung.com/t5/Wearable-Tech/bd-p/wearabletech and on the EU equivalent.

Has anyone been able to get it working with a external chest strap?

I just got my GW 3 days ago. I did a test run today, and it seems to me that after my hr got to 104rpm, it lost reading.
SInce this is the only run I have tried with it, and it was raining, so I am not sure what is the actual cause. But your findings are really helpful, at least it gives another perspective!

Swimming workout 10 min 3995 kcal

Does anyone have problem with swimming tracking on galaxy watch?
After 10 min of swimming, it says I burned cca 3995 kcal which is insane.
I tried it couple of time, and every time got same result.
Other types of workout seems to work fine

I've tested it yesterday 2x, same bad outcome. I waited for it to lock GPS before start. It recorded time 13 mins correctly, but 0 m distance, no route on map, and* a ridiculous calorie count (2300). Samsung health did a terrible job with the open water swim mode.

Gps can not work in or under water, so if you swim normally, with both arms in the water, it can't fix the hole time of swimming.
The cal count is really bad, that's true :/

I don't know. Maybe if you swim the crawl it can work? But under water there is nearly no way to get a fix.

I just tried emulate swimming at home, after 5 arm movements and walking around 10m, I burned 300 kcal

I used swimming (pool) 6 min swim for 51kcal.

Active Watch not tracking swim distance in pool.
GW Active stopped recording distance/laps while swimming in pool. Eg. 30min Swim 0m. Any ideas for a fix? Thanks XDA
