Since I knew everyone would think I lost my mind, I verified this for weeks before posting it...so here it goes!
When I charge the device at work (with the power on), it sits on my desk about 16 inches under my overhead cabinet that has fluorescent lights underneath. The lights somehow triggers screen actions on my HD2! It's the strangest thing I've ever seen! After about 30 seconds, the device looks like a ghost is randomly tapping the screen, randomly starting programs!
This NEVER EVER happens in any other condition--outside under sunlight or while the device is on any other surface where the fluorescent light is higher up, like on the ceiling. I have no problems with using the device otherwise.
It's just strange and I'm wondering if anyone else has ever seen this...
hmm interesting.
Might there be power running up inside the wall near the phone too? PC and monitior around it?
could be patches of field building up just enough to fool the capacitive screen, or maybe exciting the grease on teh screen or some such.
Course there has been a lot of talk about ghost taps, is it really only ever happening there?
Could be you need to change the starter plug in the fluorescent, if its a standard strip, they can hold quite a charge, and if its on its way out it could be losing charge to the air.
Especially when you look at how many electrical items we have on/near our desks, easy to build up a standing charge.

Someone also mentioned the fact that the flicker on my fluorescent desk lamp could be the cause. I saw a video where someone was able to "tap" their capacitive screen using beams of light, lasers, etc.

Is anyone else having an issue with phantom taps on the screen. I know sometimes my screen will pull up the keyboard and start typing. Or if I am scrolling a web page it will think i'm zooming. Or if I go to click and hold a link in dolphin it will just click.
yeah while browsing i had the same problem, maybe some bug that will be crushed after an update.we have to bare with this in the meanwhile.
I'm reading on other forums like the Nook that a screen protector may help fix this.
Plugged in?
Does this only happen when the flyer is plugged in? I had this problem when I was trying to use the flyer while it was plugged in and it just started doing as it pleased. The first couple of times it freaked me out! It just started typing crazy stuff and started navigating from screen to screen as it saw fit every time I went to touch the screen. I thought it was demon possessed (some kind of ouija tablet), but I didn't call a priest I just unplugged it and all was well with it's formerly possessed soul.
.
I have a problem when It's plugged into the power. Scrolling pages sometimes zooms and buttons can activate if my finger is just close to them.
In some countries like here in the UAE, the combination of badly earthed mains, leather-soled shoes or bare feet on tiled floors and a very sensitive capacitive screen causes strange tap response.
Ever held a charging phone or laptop and felt a slight electric buzz??
I usually find if I clean my screen and remove any finger grease, it tends to work fine after that.
Also, even if not on power, I have found a problem with tap and hold (say to trash icons) that if you press the screen too hard, the hold does not 'hold' ... If you use a light tap it works fine.
Large finger surface area on hard press seems to confuse it.
It happens when it's not plugged in.
My screen was so sensitive it would open apps, etc. even when my finger was 1/2" away from the screen. It was frustrating. Cutting down one of the matte, anti-glare screen protectors I had left after I returned my Galaxy tab solved the problem.
I bought some screen protectors of Amazon... Thanks for the input... its the only downside to this thing :-D
My nook tablet was opening apps like Facebook and google search and typing unusual letters in the search and status boxes. Anyone seen anything like this? It honestly seemed like the device was being controlled remotely. I wasn't even touching the device and it was trying to type letters. My device has been rooted for about two weeks. I've not seen anything like this until tonight.
What was your battery charge? There are reports of the touchscreen acting weird when the battery is low.
yea, sounds more like a glitch in the touch screen. this happened on my phone. I would warranty it. Make sure you unroot first
It sounds like a defective unit... I have a Droid X that does the same thing; started happening about a month or two out of warranty. I've factory reset / SBF'd it a million times and it still happens, rooted or not.
For me, it seems to happen more frequently when the screen is dirty (but also happens when perfectly clean), and especially bad if I am wearing clothing that generates static electricity (fleece and other synthetics). Makes me wonder if the screen isn't grounded properly.. the phone has a lot more flex in the chasis than it should and sometimes flexing it in just the right way will make the problem stop.
Thanks
Thanks much for the replies. The battery was very low and I was sitting in a chair that could generate static electricity. Also noticed little bits of dog hair caught between the case and the screen. Not sure I'm going to return the unit just yet. It could have been a fluke. The only time I've seen a machine act like that is when someone controls a server at work remotely. It was really strange and seemed like a program was attempting to type on its own.
One other caveat is that I had installed Aurora on the tablet earlier in the night. It's a browser by Mozilla in development. It was running really sweet so I don't think that had anything to do with it. I did notice that the tablet was locking up on a couple pages and really sluggish for a bit while using the default browser. It then responded fine until the ghost took over.
One other question if anyone is still listening: if this happened to you did the keyboard come up? It didn't appear when the letters were being typed in my case.
I was thinking a cover and possibly a shield may be in order. I've got a year, so it if happens again even one time I'm going to return the unit- after unrooting of course.
My Nook Color will do this as well when it has been zapped by static electricity and when there are a bunch of finger prints all over the screen (usually when the finger oil gets built up around the edges of the screen it starts).
A good wipe down with a microfiber cloth (with the screen off) fixes it for me. Granted this is Nook Color and not my Nook Touch we're talking about, but I figure the behavior could be similar.
Good luck!

Weird, I could swear there was a thread about this, but now I can't find it for the life of me.
Anyway, it's a known issue- no need to panic and return the NT.
When the battery gets critically low, sometimes the NT will seem to have a mind of it's own and everything you describe starts happening. Apps open themselves, random text types itself, touchscreen completely unresponsive, etc.
I've seen exactly the same thing, and also at first wondered if it was a remote hack. Then I noticed the pattern that it's only during extreme power lows.
Just recharge to at least a minimal level and there's no problem.

Ah. I knew I posted there, but thread is strangely missing from my 'find all posts..' results.

Same thing happens to me but I only switch the screen off and on and then it goes away.
As has been mentioned, charge it, clean the screen, wash your hands. This should take care of the "autogibberish". As far as opening software... do you mean that it is opening foreground applications? Or that software will just load in the background? If the latter, this is NORMAL behavior of Android -- it will load software into memory so that it is instantly available when you try to run the software. If the former, probably related to the dirty screen.
I do NOT believe that this is a hardware defect. It rather is a side-effect of a LARGE touch surface. The bigger the touch surface, the more likely it is to be subject to random static charges.
Whoops didn't realize how this thread was!
Stupid Question..
Has anyone burned here burned out a smartphone's camera flash?
I used the "assistive light " last night and put the phone down, but I guess I forgot the turn it off..When I got up this morning and picked up the phone, the flash was still on.
I know that LED's have a conditional lifetime of thousands of hours, but I was just curious if anyone burned theirs out due to heat or excessive use, etc.

It's very possible and I have seen people melt the lens for the LED, since the LED is only meant to be a flash and not run continuously. It can get quite hot too.
Has anyone else had issues with their back light faulting? I've searched and have seen that other sprint evo lte users have had issues with screen flickering, but my problem seems to be more serious that that. when i wake up in the morning the screen is blank. thank god i have a custrom rom installed and can manually mess with the status bar slider to get the backlight to turn back on. It just needs to be tweaked here and there. the backlight seems to only like to work on full brightness, if not, it will flicker like crazy. if i press with more pressure on certain parts of the screen the backlight turns off completely until i remove my finger. I dont think its a proximity issue since it'll just flicker sitting on a desk. Do I need to replace the screen? is this worth it? i havent dropped to phone or anything for this to default. I can upload a video later. gonna use my OG evo for that which is still kicken by the way
I realize this thread is incredibly old, but did you ever find a solution to the flickering problem? I just started seeing the exact same behavior, including the screen going dark when putting pressure on certain areas of the screen.
Thanks!
I have a PJ75100 doing this, but the screen does not function at all. I get the orange/green light while charging, and if I power it on it acts as if it's doing it's regular startup, but nothing shows on screen.
I did update the stock firmware with the latest release ruu, but still no screen.
I'd really like to get this one going as it's not the normal Jewel, it's the white and silver one, and my girlfriend wants it to replace her iPhone 5c.

Hello everyone,
As the title suggests I'm now another proud owner of the Samsung Galaxy S6 Edge (SM-G925F) and immediately a few questions rose.
First of all, I unboxed my device and did the first power on. However, I noticed something weird. From the 1st power on it only had 3% battery ! Is this normal guys? From all of the unboxing videos I watched on YouTube all of them where 40% + after the 1st power on! Is it normal to be so low ?? So, I immediately shut it down and got it charging.
Second, after plugging it in to charge it started from 0%. Probably it even lost these 3% it had lol. Anyway, charging started nice and fast but I noticed another thing. The phone got really hot while charging! Is this normal again? The back was quite hot and the aluminum bezels on the sides as well (especially side lower parts). I know that this device has fast charging so it may be this and also maybe that it started charging from too low , 0% .
(UPDATE: now that it is at 99% it's has really cooled down)
My 3rd question is probably a foolish one but forgive me please. :silly: When I got it out of the box, since I'm a crazy perfectionist, I started examining the body of this jewel with a really bright torch light hahaha. Everything seemed flawless apart from a couple of tiny little marks on the lower left part of the home button. (not scratched some kind of marks like tiny glue residue maybe) They didn't get away after wiping them, even with little water on a cloth. Also, they are not really visible. Maybe they are a bit in really bright conditions but still you should look for them to see them. So, are these kind of tiny imperfections normal too? I guess so, but just wanted to say hahahha.
One more. My heart rate sensor seem to have a little plastic protector applied on it. Am I right? I'm quite afraid to pull it so, is there a little membrane there? In camera, I'm not sure.
Thanks in advance and have fun happy owners!
When I got my first smartphone, the Motorola Droid Ultra on initial boot it had 1% battery, so battery being low on first boot is not unheard of. Yet you are right that it should have 40% on initial boot. The battery going to zero before going up again is something I have experienced as well. The phone getting hot is expected with how rapidly energy enters the battery. The last two I am unsure about. If you can remove the plastic do so

Thanks for your quick response!
Alright, so yea the low 1st power-on battery seems normal. I also asked Samsung and they say it's normal since they don't set any specific charge amount from factory but they just use it as much as needed (for quality control, I assume).
About the heart rate sensor yea, I realized that it has a little protector film which can be removed.
Also, what I told about the little "marks" on home button let me explain. You can't actually see this normally. You have to have your home button fully clean and then point a bright torch to it and then look carefully on the bottom left part of it and you can see some tiny little "marks" but still can't see them at every angle. However, they are not scratches, it may just be some little debris or glue residue under the button surface, probably on the fingerprint scanner. (maybe during assembly) But again this is from a crazy perfectionist's eye! :laugh::laugh::laugh: You can't see it in normal use. I guess if you take many S6 Edges out of the box and start examining them with a powerful torch, mm by mm for sure you will find different kind of "imperfections" in any of those. This thing must be the same for every device. But I like doing it just to know if there's something there in the first place.
Also, about the warm up thing. I updated to Android 6 and performed a hard reset afterwards. Also I disabled fast-charging from the menu. (don't know if it's also disabled when you charge the phone fully shut down tho.) In normal use the temperature is fine. When charging tho (when shut down) it warms up quite a bit on rear and on side bezels. So, you S6 Edge does the same?
Thanks a lot.

Also, 1 last question (detail style again).
When you start up the notification led lights dark blue and then lighter blue in sequences. So when it does that, I can tell that there is a little "2nd" led that lights up on the right side of the notification led and makes it brighter blue. My question is that, can you see that in yours? I ask this because in my Galaxy Alpha you can't tell where the "little leds" are but you just see a clean light changing colors. On S6 Edge though, you can tell that the notification led area must be somehow "splitted" so like there is "another little led" on the right side lighting up and changing the color. Is it the same to you?
Thanks
The low battery percentage you had in your phone is just normal.
The phone gets hot when it's being charged especially when it starts from a very low percentage. Do you imagine the amount of energy getting into your phone's battery? That's a lot.
Speaking of leds, mine has the same too.
Hope you have a great time with your phone!

Thank you man. I noticed something else too though which worried me quite a lot. I will post it on another topic itself though so it can maybe be helpful for other owners too.
