[Q] GT-P7100 blue led - Galaxy Tab Q&A, Help & Troubleshooting

He folks, i have a question regarding the blue led next to the front camera on the device. It seems to only turn on when the device gets turned on and after that the light remains off even when i get an Email or IM notification. I would like to know how to get it to work because i ocassionally leave my tab in my room when i go down stairs and i dont want to turn on the screen everytime to check if i have recieved anything.

I have the same question and I have been asking everyone but no one seems to know. I even asked the samsung rep and he wasn't sure. For a second there I thought mine was faulty lol

this section is for (p1000*) 7' 1 gen only, move to right section

oke, hmmm, would it be possible to use the led of the camera? i mean would it be possible?

[PROBLEM] Died?

Hey guys, I was wondering if somebody would be able to maybe help me diagnose the fault\problem part with my non-working diamond...
Basically I went to a club one night and the place was unbelievably steamy / humid. My phone was working one minute and then the next it wouldnt display anything on the LCD. The backlight was working however.
Since then I havent been able to get an image on the screen although when trying to turn it on, it seems to go through its startup sequence (backlight -> vibration -> beep (i think))
I havent had any power to the phone since a day after it broke (a few weeks ago).
I'd like to get it back working again but dont know exactly what part i would need to replace. I'm fairly competent with electronics .
Any help/advite would be appreciated!
Haha, ok that's odd...
I've plugged it into my pc to get some data files off about an hour ago.. forgot about it and just looked at it now and the screen is displaying!
It is displaying and accepting input although it was flickering at first (like pixel shifting). but i pressed the power button to standby the screen and pressed it again and the display is fine with no flickering ?
Ive moved the phone about and shook it quite hard to see if there's any loose connection but the display still seems fine..
Anybody have any ideas as to what it may be?
I'm not going to deem it as fixed until I know what the problem was/is lol
cheers guys
Ok screen actually keeps flickering nonstop, and sometimes 'fades away' to gray/white/black
comes back after a few seconds though
Looks like a faulty connector?

[Q] 5 minute old Note died already

Hi Guys,
I was setting up my note, had my emails in there and when I clicked on the account the screen just went black. Now I can turn it on but the screen will remain black, I can pickup calls and hear texts arriving but the screen is still black!
Anything I can do? Nothing happens when I try and load recovery mode!

You just bought it?
Sounds like a hardware issue...
Arrived 30 minutes ago It was working and now isn't
And where did you bought it?
I think flashing a new firmware won't show any result because you said you can still handle it but the screen stays black.
Expansys.com usually good! Yeh I think it must be hardware rather than software....
It's now working again??
And what have you done?
I put the protective film back on, and maybe it realised it didn't want to leave me and so started working! I'm still going to get a replacement one just in case though

Good call. I would too!
Stopped working again....
take the battery out for 5 minutes then try again
how much charge is in the battery? have you let it fully charge up?
It said 66% last time it was on. You think charging fully will sort it out?

[Q] HTC One (m7) Green LED not working

I currently have a stock HTC One in Canada on the Telus network.
The last few weeks i noticed the LED light growing dim. About a week ago the phone rebooted itself only to say it had an issue and that it was not shutdown correctly.. and asked if i wanted to report the problem to HTC.
The phone the froze with the Screen on but a black background.
After 15 minutes i powered off the phone.
At this point the phone would not power back on.. when i plugged the power in to the phone from the wall the phone would not indicate that it was charging via LED.
I tried booting no response.. no vibrating,.. just slight flashing lights on the Home/back buttons
I ended up booting up the phone by shining a bright light into the light sensor while holding Power and DOWN volume..
Phone has been working fine ever since, however still no LED.
I did a factory reset and still no LED.
Has anyone see anything like this?
I want to root and install Google Edition Android however if the hardware is faulty i dont want to risk voiding the warranty and being stuck with a faulty phone.

This has happened to me too. Just one day noticed no led light anymore. Strange thing to break down on a phone! Have you had any joy in getting a fix?

Unfortunately I have not been successful getting the LED back.. I am debating sending the phone in for Warranty work... or just sucking it up and rooting/flashing custom roms.
My main concern is that there may be a bigger hardware issue going on internally.
I'm really just trying to get a feel of how common this issue is..

Try this: in dialer type *#*#3424#*#* (3424 = DIAG), that will bring up HTC internal diagnostic, there's a "LED Test", select and run it to see if it's a hardware defect or not (you will get Orange and Green LED tests).

Thanks for the info.. Just tried it the LED test .
To my surprise the Green and Orange lights actually show up but I have to hold it to my eye and block out any external light to see anything.. kind of defeats the purpose of an LED notification light..
I guess the light works its just extremely DIM.
Any way of controlling the LED light brightness?

Don't know, but I just ran the same test in a very well lit environment and the Green and Orange LED are quite bright... I don't have to "go look for them" they pop out nicely.
Are you using a cover of any kind? Or maybe the LED has somehow shifted it's position and is being partially covered by the speaker grill? Hate to say it, but sounds like a hardware issue. Sorry
Hope someone else has other ideas.

Not using any case that would cover the LED.. that being said even with the Case off.. the LED is still very dim.

Shouldn't affect it. I've been using ARHD 9 through 13.3 and works with all of them.

I've ran the LED test, and all of them work. But they dont light up for notifications, and i have it enabled in the settings.

I have the same problem. Did factory reset two times. Red when charging, green when full but no flashing green for notification. I enabled it in settings.
Have you manage to find a solution for the problem?
Thanks.

I am having the same issue! The light works, but it doesn't blink for notifications!!

I also have the same problem: when it is charging and when it is fully charged the light works OK but doesn't flash for notifications. But it worked OK some time ago. Actually, when I think about it, it seems that the problem started after I had updated to the current firmware: Android version 4.3, HTC Sense version 5.5, software number 3.62.401.1
It must be issue with firmware/software because LED test works fine.
There's another thread similar to this one and someone there figured out the solution - you do a factory reset but, when the phone reboots, you do not restore everything using your Google account. Go through the setup as normal (without restoring) and once that is complete then you can add your Google account details.
It means you have to download and set up your apps again, but it is worth it to get the LED working.
HI I had a similar problem I cleaned out the hole with a needle and all is well, pin came out dirty (the one on the grill dirt was blocking led )

[Q] Active Display turns on when phone is moved.

This might seem like a dumb question but whenever I set my phone down and it is moved even in the slightest the Active Display lockscreen turns on. Is there anyway possible to disable that?
That's the cool thing about this phone. Don't worry about it

You will get used to it and come to love it. the great thing is that it doesn't adversely effect your battery, it uses the special built in processors. I thought it was weird at first but now I just tap my phone or bump the table to see my notifications.
I love it because I never have to push the power button to turn my device on. This is a great way to save wear and tear on your power button. A lot of devices that rely on one button all the time (power button) end up with that button not working anymore. If I didn't have this option I would be using my volume rocker to power up my phone.

This is easily my favorite feature about the Moto X. All I gotta do is pick up my phone and it automagically shows me any notifications and is ready to be unlocked. Power button? What's that?
Sent from my Nexus 5 using XDA Premium 4 mobile app
I like this feature. I usually tap my finger on the screen or press off to one side so the phone rocks slightly on the curved back to get the display to come on. As someone else said, it saves a lot of wear on the power button. I can't tell you how often I clicked my Razr Maxx on just to see what time it was, and clicked it off again immediately. The button never wore out, but it's nice not having to do it at all.
I do have a question though. I got the phone on Wednesday and didn't notice this at all until this morning, and I don't know if it's normal or not. While getting ready for work this morning I noticed the Active Display fire on and off a few times in a row. I thought since it was right at 7am that I may have gotten a few emails close together or something, and didn't worry about it.
When I got to work I set my phone on my desk and was reading emails and such and I noticed the display puling on and off about every 5-6 seconds. It fades in, holds for maybe 1 second and fades out. It only had one notification, for Plume (Twitter), which only polls every 15 minutes in the background, so I knew it wasn't getting new notifications repeatedly.
I can't remember if this was happening yesterday and I just opened it up right away to see what it was for, or if something actually changed. I disabled Plume from the Active Display list, which didn't change anything, I got the same result for email (Maildroid) and Snapchat.
I guess it kind of makes sense that it repeats, as there is no LED on the phone, but it seems a little excessive. I don't know how much power is saved by using white on black in the small area of the screen, but it's bugging me a little because I don't remember it doing this before.
Thanks for any input anyone has on this...

It's normal. When you have a notification, the screen pulses instead of having a notification LED.
I haven't measured it, but it's my impression that it slows down the pulsing if the phone sits quietly for a while after the notification happens (I seem to notice that, if I ignore the notification, I don't see it as much). It really uses almost no battery, though, so don't worry about it.
Does the phone always light up when driving? I don't remember it happening on my old X but it's lights up at every bump on my new X.
Thinking I've frozen something I shouldn't have. Did not use assist on either phone.

Thanks for the quick reply. I'm guessing yesterday I either cleared them quickly, or they were present long enough to go slower and I didn't notice the repetition.
I will have to play around with what I actually want notifications for. Plume (Twitter) is the worst, followed by email. I wish I could turn on different channels for Plume so that Mentions/DMs could go to Active Display, but regular tweets didn't, but still have it do all in the notification shade. I might have to just settle for not getting a notification for all new tweets. Or increase my poll time...
Email might get shut off too. I get too much spam to care, and rarely get any emails that are urgent enough to warrant it.
Yes, mine lights up when driving Lol. The second I press on the gas it lights up, tripped me out the first few days owning the device, but I'm used to it now.

How to stop the screen lighting up.

Hi all, just got myself a LG GWatch R, and loving it so far...
Just a couple of questions...
1: The screen keeps lighting up when i move my arm?, this is causing extra battery drain and i dont want this to happen, ive already set the screen to always on in ambient mode so wht does it keep turning on to full?
2: It keeps saying google now is not available even though its connected? Annoying.
3: The same cards keep appearing even though i have swiped them away. Why?
hi,
try a reset of lhe lg r
Have you run all updates? Yes a reset may be in order.

1) You can no do that. Just mute notification by swipe down watch status bar, it mute notification and disable the lightin up movement.
2) It need BT connected watch/phone AND valid internet connection on phone.
3) card appear when phone send notification. If card appearing after swipe, it is your phone wich notify again.
1: STUPID, I dont want to turn my buzzer of to stop the screen lighting up.
2: All is connected but the watch does it constantly.
3: Cards dont appear on phone just constantly on the watch?

which particular card is annoying you? i do find the light up mechanism is annoying as if i turn my wrist to do something and the screen just light up.
i wish google or LG is able to come up a new features to stop the auto light up function by movement. on pebble, you can disable such function...why google cannot..
Well I tried emailing them about it. But after sitting there for half an hour entering crap just to send an email I gave up.
I'm on holiday this week. And I keep getting a card saying holiday all day. But this keeps popping up about 20 times a day. Doesn't appear on the phone just the watch.
According to the screenshots in this article covering the upcoming Android Wear 5.0 Lollipop, we will be able to disable the wake gesture!
have a close look at the screenshots of the AW phone app, there is an option "Tilt to wake screen"
the holiday is mark in your google calendar? if you didnt connect the phone with watch..did it happen?
No its coming from the phone. But I don't understand why it appears all the time instead of once
I would also like it too not light up every time I move! I have turned off all gestures and tilt to wake but it still lights up. Just want to tell the time not let everyone know im wearing a smartwatch.
