Hello all,
Has anyone been able to access the LED flash on the Nexus one without rooting? I would like to create a flashlight app of my own to do this, but I have no idea where to begin.
from the market n1 torch.

I love incorrect information said with such confidence, lol.
n1 torch, as has been mentioned, is root only. Heck, if you go to download it, it SAYS it. Beyond that, unfortunately no, at this moment from my research, you'll need root access to gain control of the LED. Sorry
Re the N1 Torch, which i love btw, is anyone else having problems with the widget?
Most of the time its perfect, but sometimes it appears to lag by ALOT, ie you press it multiple times to try and turn it on, then a few minutes later in your pocket it starts flashing on and off while in your pocket.
i prefer the color flashlight one, i think thats what its called, it doesnt use the led it lights up the screen itself, much brighter and wider light imo
use it while sneaking up to bed after late night raids in warcraft so i dont wake the g/f
I used that one last night to read, I see what you mean about its much wider, but its definitely NOT brighter than the LED, although that only lasts for like a minute before it needs to cool down.
Hi I am new to android and am considering switching from my iphone 3gs to a nexus one (or possible samsung captivate) It would be great if yall could answer these questions and any other helpful information you have on the phone!
1. How are the touch sensitive buttons on the bottom of the phone? Do yall ever have any trouble activating them or anything?
2. How is the battery life on this phone? I use my phone for texting ALOT, probably 5000 messages a month. Will i still be able to get a good days use out of the phone? That's all i really need because i charge it at night anyway. Also does rooting the phone and installing different ROMs or kernels improve battery life, or any other improvements over stock android? If so, which ones would you recommend for this.
3. I've read about screen burn in and some touch screen issues, have yall experienced any of these first hand?
I would be very appreciative if you could answer these questions for me
1. How are the touch sensitive buttons on the bottom of the phone? Do yall ever have any trouble activating them or anything?
I don't but my wife does. However, she tends to mash the screen with the side of her thumb because she is a blackberry user and has long nails. As an iphone user I'd think you'd be fine. You'll LOVE Swype.

My N1 lasts all day easily, unless I'm doing something crazy like wireless tethering without a charger. That said I have a 2nd battery on a home charger because I hate (or badly forget about) leaving my phone plugged in EVER. Mostly I swap the battery in the morning on my way out. Froyo boots up fast!
3. I've read about screen burn in and some touch screen issues, have yall experienced any of these first hand?

Have not noticed any burn in issues yet. The contrast on the N1 AMOLED is a gorgeous thing to behold. It has a nicer image than my LED backlit Samsung TV, which is no chump.
However, the phone's screen struggles terribly in direct sunlight.
1. Touch buttons have been improved and are more responsive after the Froyo update.
2. Can be be good, can be bad. Should last you the day, but with heavy texting i wouldn't know. If you unlock and root it you can experiment with different roms and kernels to improve it. When i got my phone with stock 2.1 -update1 the battery was average. But then i unlocked it and flashe Cyanogen ROM and the battery got way better. So it is up to you. Unlocking and rooting voids warranty, but HTC have been kind to fix/replace phone as long as you re-flash stock to it.
3. Has happened to some. Mostly i think is due to the white status-bar that with long use on highest brightness. It can happen because it is fixed on one place allowing the white and bright burn gradually into the screen. Like the old Tv's (pre-plasma) you know. Leave it on overnight with a still image actually burns the image on the screen when turning it off. Old news really . Again, rooting it will allow you to install a black status bar thus eliminate the threat of a screen burn.
Most phones like these struggles in sunlight. But when beefing brightness to MAX it actually is "OK" to use it in the sun.
i have the slight burn in. its very faint and you would not even notice it AT ALL its that minor. but the problem is google made the status bar all white, and it never moves from that position of the screen no matter what you are doing with the phone. so because its amoled screen, those pixels wore out slightly quicker.
there is an easy way to avoid this problem, change to an all black color status bar. problem solved however you need to root in order to do this. good news is that now you can root without unlocking the bootloader, so HTC can never tell the phone was rooted, in case you were worried about voiding the warranty.
How can you root without unlocking the bootloader? And how do you change the color of the notification bar? Is there a simple themeing application like there is on jailbroken iphones?
Look in Developers section for the non-unlocking rooting thread.
(personally - I don't live in US so warranty means nothing to me, my phone was rooted after ~2 hours I took to check intact parts functionality).
Look up "Metamorph" in Apps section.
Another question, my girlfriend recently got the mytouch 3g. It works pretty decent and everything, but it is quite noticeably choppy. I would assume the nexus one is very smooth due to the 1ghz processor?

If you want to donate, or more features, check out Keep The Lights On Pro.
What does it do?
Keep The Lights On is a simple app that performs one function. It keeps the LEDs behind the buttons on a Captivate or similar phone on while the screen is on.
That seems stupid, why would anyone do that?
Well, try finding those buttons in the dark. While the stock ROM turns on the LEDs when you touch the screen, the i9000 based ROMs do not. In addition, most i9000 ROMs have a timeout of 3 seconds.
Doesn't that waste battery?
Depends on what you mean by waste. So first you have to understand the scale of battery consumption I'm talking about. LEDs, especially surface mount ones, draw very little power. How little? Assuming typical LEDs, we're talking 5 milliamps at 3.3 volts. Given that there are 4 LEDs, that means the total power consumption is 0.005 * 3.3 * 4 or 0.066 watts. The CPU consumes between 100 and 1000 milliamps, again at 3.3 volts meaning it uses between 0.33 and 3.3 watts. That's 5-50 times as much power, and that's before adding in the backlight, radio, etc. While yes, technically this uses a little more power, the scale is so small that for all intents and purposes it isn't going to make a difference in your life. Seeing the buttons clearly though, that takes frustration out of your life. Seems like a reasonable trade off.
Does it work with other BLN things like Blinky or BLN Pro?
Yes. This uses a different way to handle the BLN than both those apps. In fact it only requires a rooted ROM with these lights to work. So that means it should work for i9000, Fascinate, Captivate, Vibrant, etc. This should even work with the stock ROM given it is rooted.
If it works for all those phones, why is this just in the Captivate Section?
Well, I only have one phone right now to test with. That is my personal Captivate.
Why are you giving this away for free? Are you drunk? Does it use ads?
To answer the second question first, sometimes but not right now. This is free because I like making people's lives easier. I do not believe in advertisement based products, so you'll never see that from me. If you want to give something back, consider the donate button or buy the Pro version.
I installed it but didn't the app in my list of apps. Is it broken?
Short answer, no. This is a widget based app. Simply add the widget and click it to change the light behavior. You can even remove the widget and it'll remember your preference when you start up. That said if you uninstall the app you'll loose the behavior.
I just got an invalid signature error. What do I do?
This is my fault, there was an early version that I didn't sign correctly. Simply uninstall it manually before installing this version from the market.
What other issues exist?
Well there's a few:
I've had one report of the lights flashing instead of staying solid when turning the screen on. If this user hits one of the buttons the lights will stay on. I'm working on a way to fix this, I haven't found the cause as of yet.
There's a superuser notice every once in a while. This is easy to turn off in the superuser app, and will be fixed in the pro version.
There's been one report of clicking a link in andchat causes the lights to go out. I haven't been able to reproduce it yet.
If you find a problem not on this list, feel free to let me know.
What other features are in this app?
None; however, I'm always open to new ideas. Be warned though, they may go into the pro version.
How do I get this app?
From the market, or here:

Suggestion
I have not tried your app yet, but I have a suggestion.
If you could turn on or off each individual LED, rather than all on or all off, then you could consider using each button to indicate something different.
Home - new email
Menu - new text
Back - missed call
Maybe you can even make them blink?

What would be the point of that with this app.....it turns the lights on when the screen is on, if the screen is on then you have those same notifications at the top of the screen already.
Though I guess it might be useful for some if those additions were made to Guardian Bob's BLINKY APP.
Support for Galaxy Tablet
First off, thanks for your efforts!! This is exactly what I'm looking for.
Any chance you will be able to support this on the galaxy tablet? I am happy to help in any way I can - I am a developer (though I haven't done much android development). I have a rooted device with busy box... if there's anything I can do to help you figure out this device, please let me know!
Crazy me, I would honestly like to be able to DISABLE these lights. I watch movies and do other things a lot in the dark, and these bright white lights randomly popping up on my phone are very distracting. Since they can be turned ON manually, does that mean perhaps they can be turned OFF as well?

Change the 0 to 1 to re-enable.
Lovin it. One of the pet peeves of this device was the short duration on the home keys.
How about this as as Pro suggestion (if possible):
Control brightness level when LEDs are on.
My cuz has a DINC and i absolutely LOVE the brightness of his home keys. Super easy to see. Possible?

Working fine so far on my Vibrant running Nero v5.
Good job, but i was wondering if there's an opposite app, one that turns off the led buttons even when the screen is touched? What for? For reading ebooks in the dark, the led buttons hurt the eyes even when the screen has been adjusted to the lowest light level. Thank

It's a widget, long press your screen, select widget, select KeepTheLightsOn.
FYI -
I'm working on tasker support for the pro version right now (well not right now, I'm taking a moment from that work to update people) but when I finish this I'll continue working on my beer, watching the Packers vs the Bears and keep working on adding tasker/locale support.
Mine stopped working, Not sure why. I have the widget and it will light up or un-light. But it will no longer keep the lights on. Any suggestions on figuring out why ?

Device: Nook Color rooted to 1.1
I had my Nook Color in the car today (40 degrees or so), pulled it out to show her what it looked like rooted. While standing in the driveway showing her different things, I found the touch screen was overly sensitive. As I was scrolling through different things (the app list, twitter, facebook), the slightest touch would select/open an item. It normally doesn't do this. It was incredibly frustrating and almost unusable. I pulled it out later and it seems to be behaving like it normally does.
Does temperature affect the NC screen? Where they any touch screen changes in 1.1? Is there a setting to calibrate the touch screen? I can't seem to find one. Any other suggestions?
I tried doing a search on the forum, but the search crashed.
Thanks.

I don't know if it's placebo or not, but I feel like this app improved my screen response.
http://forum.xda-developers.com/showthread.php?t=934500
As for the other question, I would expect the screen to be less responsive in cold weather, but I don't have anything to base that on.
Guessing what you experienced was due to condensation on the screen. Doesn't take much and can be 'invisible' to you but the screen is sensitive to 'stuff' on the screen and will become overly sensitive if there is anything on it, like moisture, skin oils, etc .. a screen protector may help but unless it continues that is probably the cause.

What you experience is probably temperature related, but another thing to try is to increase the LCD screen density to around 190, 200, or a little more. For me, I get improved sensitivity, especially near the corners.
My daughter accidentally got a little water on the screen and it was a little erratic. I put it in a ziplock with a handful of rice for about 6 hours and it was like new.
I have owned 3 nook colors, the first one I owned freaked out when I used a damp cloth to wipe the screen. It exhibited some strange behavior and emitted some loud static from the speaker. It would not power down or anything... finally it just went back to normal, so I took it back to B&N and then went and bought one at walmart. I took it back because I thought I wanted the Viewsonic G Tablet. But after trying it I finally bought a Nook Color at Best Buy, bought a screen protector too so that I don't have a repeat of my first NC. The screens on these things are, I believe, rather sensitive and the cold or the moisture may have played a part in your unit's behavior.

Same here. My screen also seems very inaccurate.
Have you found a fix?
Sent from a NookColor using the xda app
I'd be interested in a solution for this as well, since the edges of my NC screen seems to be a lot less sensitive. For instance, when the Market is launched, it takes 4-5 tries to hit the search button at the right top corner (I know that I can hit menu and select search from there, but I am trying to illustrate my point).

this modified kernel solves that

It's funny, actually... The cold makes your skin less detectable because of vasoconstriction in your fingers as a physiological response to the cold temperature, but a hint of moisture by means of condensation has the opposite effect.
For me, condensation is rarely a problem, but the decreased capillary blood flow effect is quite noticeable.

One thing that's been mentioned before (and the B&N salesman told me while buying a screenprotector) is that if the screen has a lot of fingerprints, it'll make the nook act weird.
Try wiping the screen of fingerprints.

Thanks for the reply. Is it safe to assume that the screen sensitivity would not be an issue in Honeycomb since it is designed for tablets? If so, I may just wait for the final release of HC before fiddling with different kernels,etc. Thanks!

final realease of HC? no one knows if we will ever have one...... anyhow, it seems to be a fix at kernel level (had to be fixed in eclair, froyo and HC), and it fact, it was discovered by deeper (the guy who ported our HC version)
my suggestion? go for it now. the sensitivity problem is way too bothersome, and it is very easy to apply

Yes, I'd love to take care of it ASAP, since I'm sick of trying to hit a small button on the screen and going somewhere else instead.
My NC was rooted with B&N 1.1 + Autonooter 3.0. Will I still be able to "apply" the changes that you mentioned on top of that or do I have to start from scratch?
Thanks!

Good test tool
I ran GoJimi's tool, and since then my screen has been flipping out. Typing anything is a good test...I enter one key like "z", and get 2 - "zm". Utterly maddening.
A good tool to see what's going on is "Mutitouch Test" from JerryW in the market.
When I press with one finger, I see a "phantom" 2nd point jumping around. Very quick way to see 1) how good tracking is and 2) if there's any random inintended multitouch action happening.
What is everyone experiencing? I have a T-Mobile Nexus 6. I am running stock and not rooted. Apologies if this has already been covered, but I searched a couple of different ways and did not see anything.
Not sure what others are experiencing, but my Nexus 6 display will randomly wake into ambient mode even when I just have it sitting still on my desk or couch. There are no alerts that are driving it, so I am just wondering if others are seeing the same thing or if they have done anything with the settings to clear this issue.
I can't imagine that ambient display is a huge drain on the battery or anything, but it's not nothing. Plus it's distracting when it happens.
I've noticed mine coming on due to vibrations. I had it sitting on a minifridge next to my desk. I thought it was random too, but it turns out I was either knocking the side of my desk with my knee, or the fridge was kicking on/off.
Mine does it all the time. No movement to the phone or even around the phone. Hands no where near it. Just decides to wake up. I find the whole ambient display to be pretty annoying altogether honestly. Hoping devs can disable it and find a way to use the LED.
I saw a weird error message from LightFlow (which I installed and enabled to see what it would do). I wonder if this or other apps that are running in the background and potentially causing the screen wakes.
I will try uninstalling LighFlow to see if it improves the situation and report back with any news.
I think you might be right. I have the same problem but I didn't notice it when I first got the phone. I have installed lightflow and now that you mention it, this problem started soon after. So I just uninstalled lightflow and it already seems better.
When I installed that double tap to wake app it messed with ambient display and would turn it on, especially when the battery was low. I removed that app.
Since then I have also turned off ambient display because I found it fairly useless and feel it is using battery for very little benefit. If it flashed faster or kept flashing until I checked it I think I'd use it.
I turned it off because I had it sitting on a table with nobody touching the table and it kept coming on. I couldn't get light flow to get the light working unfortunately, hopefully there is a fix coming.

root phone, install light flow, disable ambient display.
it's already been done.
i use light flow and it works perfectly, sans flashing LED but that seems hardware/kernel blocked.
It seems that LightFlow is what was causing the issue as I haven't noticed the screen waking since uninstalling it yesterday.
