Using track ball to wake phone screen?

Would it be hard to program the trackball to wake to the lock screen rather than having to hit the top button. I find it very annoying and it would be so much better for one handed use.
(this thing is slippery!)

It bugs me a bit too. When I had an iPhone I almost always use the home button to bring the unlock screen up. Also my nexus one is a bit slippery too I want a case.

I would be more interested in using volume keys to play/pause/forward/rewind the music payer without waking up the phone. This was one of the applications in iPhone.

If you're playing music, the volume keys are still able to adjust the media volume while music is playing and the phone is locked (and the screen doesn't turn on while doing it either). I prefer that behavior actually.

That's the one thing that always bugged me about the Droid, and what do you know... the N1 has the same problem, lol. Anyway, there has been a lot of discussion about this (including here: http://forum.xda-developers.com/showthread.php?t=613678&highlight=trackball). There's a thread in development as well about maybe mapping that function to the trackball... who knows.

CLOCK APP
I just realized if you open the clock application, and let the phone go to sleep, then you can "Turn it on" with the trackball or volume rocker.
Now if there was a way to have the phone set to "Sleep = Clock" we'd be golden; the clock screen doen't look that bad, either.

Lots of great thoughts here. Bump.

I hated this as well!
I found a solution! (sort of).
"Lock bot Free" from the android market is what i use now.
It enables you to pick differnt lock screens ( i like the hero one since u just scroll downwards to unlock) and it allows for u to press the trackball to wake up.
I have found that it is kind of buggy still. If i reboot the phone, I end up with two lockscreens. The regular nexus 1 one and then my hero one. So i had to reinstall it for it to work properly.
Disclaimer: I am not affiliated with that app. I just found it on my search to make my N1 less annoying.

I was about to come post this same thing, although I'm experiencing a weird glitch too, but I actually like it. For some reason I don't get a lock screen at all after my phone locks. I hit the trackball/volume keys/power button and it just goes straight to whatever screen I was at when it locked. Pretty sweet actually.

This is Very good, if it was working
it randomly locks or not the screen which is Unaxeptable in my pocket

I tried the alpha3 of myLock. It... sort of worked, except that every time I unlocked/woke the screen, the app itself would toggle itself off. No idea why; it's not like I even have a task killer anymore.

Lock 2.0 from the market works well.

does that allow you to have a regular or hero lockscreen?
ALl i saw on the screenshots were Iphone lockscreen ripoffs.
And if i wanted an iphone i would've gotten one. Why you'd want to make your N1 look like an iphone I can never figure out.

Trying Lock 2.0 free, so far it works pretty good. I can't change my lockscreen pic and I don't like how it goes to the lockscreen when touch home...

What I don't like about Lock 2.0:
1) If you wake up your phone by accident (and don't unlock the phone) it doesn't go back to sleep after a few seconds of inactivity,
2) it doesn't show your notification bar so you don't know whether you got a new email or text message or other notification.

Have you even looked in the settings? Please examine the app more closely.

Using Lockbot free now. Does what I wanted perfectly (press any hard button to wake up), plus lets me use the Eclair lockscreen which I've always found more aesthetically pleasing.

Installed Lockbot Free, and it does exactly what I want with the trackball, but I can not work out why sometimes it gives me the Eclair screen which I like, and sometimes it chooses a different screen?
Kev

You have to uncheck the stars (I can't remember specifically) next to the unlock screens you do not want to show up. I never liked LockBot, it isn't a precise copy of the real lock screen(s), if I'm going to use a imitation I rather it look complete..

Open up the app, press "My theme." It'll give you a "playlist" of different lock screens. I simply un-star all the ones I don't want and stick with Eclair after changing the background. The clock's font is a bit off, but I will cope.

App idea: Alt+Tab style, single click switch to previous app. Exist already?

I I have looked all over for an app to do this but have found nothing. I am ready to start writing my own, but want to make sure it doesn't exist already? Seems hard to believe no one has done this yet!?
say i need to copy/paste listing descriptions from evernote into ebay... I want a QUICK trigger, maybe double tapping home or something that shows a simple app list in a transparent overlay.
Pick the ebay app and it loads. After pasting the title there, double tap home again and instantly, it flips back to Evernote where I can repeat this process with the description and other fields. Maybe the volume key could flip between the two apps, or better yet, a swipe.
Seeing how I use that technique a million times a day, it would save countless hours over all the other task manager types that always load a display of all (or none) of the recent apps when triggered. I don't know about everybody else, but there's a 90% chance that if I want to quickly flip to another app, it's because I intend to quickly flip right back in a few seconds.
This is such a vital function for me on computers that I dedicate a whole button on my mouse to pressing Alt+Tab so I can flip back and forth very fast. I have become very spoiled by that technique and can't stand doing work on Android just because of its annoyingly slow and painful "task manager" if you can even call it that. TIA!

I am sorry, but you cannot override the home button.
You could try one of the various side bar apps though.

It could be a swipe gesture or anything that requires only ONE step. I don't want to bring up an app selection list on every switch, but just the first time. Maybe a notification bar button could bring up the selector, then a side swipe gesture could flip back and forth between the two apps? It should be simple to write this. I just cant believe that it hasn't already been done? Surely someone knows of an existing app?

The problem is that the part of the screen which will be "swipeable" will not react to touch events anymore.

Yeah. But it could be a small invisible hotzone like many of the task managers do. Swiping is just for the cool factor really. Using the volume button should work just fine for my needs. Would that work? The volume button can still listen to an app thats not in focus because music players do it right? But i guess that would be a problem if one of the switched apps overrides the volume control...? Any suggestions? If nobody has pointed out an existing app with this capability I will start on it tonight. I'm still a newb to Android but, I am majoring in programming so I gotta jump in on something!

if I understand correctly you just want to have multitasking without having to hit the multitask button and then choose the app; you just want to be able to choose the app. I would say something like floating folders would work for you.

Disable changing watchfaces (long-press)

Hello all.
I don't think anyone has asked this before, so here it is.
Is there a way to disable long-press to change watch face? When I happen to cross my arms, it tends to hit the watchface and registers a long press and goes to the face selection screen. It is pretty annoying as it vibrates and there is a tendency that my face will get changed.
I rather just have the ability to change watch faces via the settings, but would very much like the long-press disabled.
Thanks for reading.
Cheers!

I´ve the same issue, sometimes when covering the screen with the hand to turn it off it changes the watchface...

Wouldn't enabling theater mode prevent that? Two taps on the crown to enable or disable.

No. Theatre mode disables the display.
It should be possible to keep the display on but disable changing watch faces. At least this way.

Yes I found it very annoying too... Google should lock that function (or at least give the ability to do so)

Thanks. That's pretty close. However, I would not like to lock the screen altogether. Normal tasks like viewing and swiping cards is fine. It's just the long tap on the face that I need to disable. I'm thinking the watch face itself needs to be amended. I'll probably ask around the WatchMaker G+ forums as I'm using it's face.

I'm not a developer, but it looks to me like that just disables touch to wake, which is what you asked for. It doesn't affect swiping at all.

I don't want to disable touch to wake. I want to disable long-press to change watchface. That's pretty specific to changing watchfaces.

any news?
Hello,
i've got an G Watch R (Rooted with an G Watch Urbane port running).
I used Advanced Settings for AndroidWear to disable WakeOnTouch, that works pretty well.
but sometimes it seems that i perfom a long-press on the watch and trigger the "change watchface screen".
Are there any News, how this feature could be deactivated? (to change watchfaces there is also an entry in the settings-menu).
LG Naith

Same problem here.
Was out shovelling snow today and I could feel my wrist vibrating to change the watch face every minute. Must have been wearing something conductive. Tried theatre mode in hopes to outwit it, it skipped passed the three taps almost immediately. As a result, the battery must have dipped 20 to 30% (or more) in that hour alone because nine hours from being on charge it's down to 50%.
I use an LG G Watch (original), so no crown to make the hack above worthwhile (unless I never want to interact with the watch again )
This happens when I bike ride as well. At any rate, any ideas (other than keeping the watch in my pocket) would be helpful (not too concerned about the battery drain effect, just the constant watch face change).
Thanks.

Anyone found a solution for this?

He is an asshole that develops such garbage function.

Software annoyances with Marshmallow/6P

I recently switched from a Droid Turbo to a 6P for the sole reason of I needed the unlocked radio abilities that the Nexus line offers and I was unable to obtain with other phones. (Droid Turbo/Moto Maxx I have plenty of threads on this around). Aside from the Verizon bloat and added software, I loved that phone.
The Nexus 6P is a very good phone on it's own, aside from the size, but I am having a few adjustment issues that some of you might be able to help me out with. I've read that most switchers from the Droid line of phones are unhappy with the Nexus Active Display compared to the Moto version. Just curious if anybody has found a worthy software that has been able to replicate or was able to port the Moto Display over to the 6P? I would be very interested and even willing to shell out $ to help that progress. The Nexus version just seems so unfinished. It very rarely wakes up upon movement and I really enjoyed how I could just wave my hand near my Turbo and I would get the time and notifications.
But my biggest issue with the software of the 6P is the fact that the bottom navigation buttons are software based and do not stay put or visible at all times. I hold the device mostly with my left hand in landscape mode and it doesn't matter which way I am holding it (the top is to the right or left) the navigation buttons are on the right side. If they would just stay put where they are supposed to be, on the bottom of the phone, I could easily use this phone one handed in landscape mode. But I cannot currently. The second part of this issue is the immersive full screen mode where they keep making my navigation buttons disappear! Ok, the screen is big enough, I do not need that extra 4 mm of screen real estate. Leave the buttons visible so I can use them please. I hate the extra screen tap and then delay to be able to back out. The video player is even worse, only allowing a small x to be pressed to back out. I've tried Immersive Full Screen Mode and a few others including Power Toggle but none lock the immersive full screen off. So does anybody know of or have a remedy to lock the navigation buttons and keep them visible? I'm also of the apparent minority that prefers the notification bar to always be visible as well.
Thanks for any help offered.

You may have to wait till some custom roms hit the scene. Sounds like a rom with pie controls would be what you seek.

Yea I was afraid of that. I was hoping there was another secret menu out there that allows control of these features.

I am annoyed with the stock messaging app...does a decent job, however it always crashes when attempting to access through the app switcher. I hate having to go back to the home screen to access my text messages.

acDisplay worked pretty well on my HTC One.

Looks pretty good, but it disables my fingerprint security. With it on I can press the power button and gain access or just swipe up. If I use the built in lock screen, after unlocking with the fingerprint, it still gives the acdisplay lock screen. Perhaps it just needs a marshmallow update to work specifically with this phone. I will continue to monitor it. Thanks for the suggestion.

I'd load Xposed with gravity box. Keeps you on AOSP and you'll have PIE, and many options for the nav bar alone.

How does one get this immersive display where the navigation buttons hide? I'm curious about this feature
Sent from my Nexus 6P using Tapatalk

It's built into the apps. The Google Photos app, any video playback, a lot of apps and games that I have automatically go into it. There's also plenty of apps, I mentioned one above, that you can install and get immersive all the time. Be aware though, I got myself into a bit of a jam as it removed the back and home buttons and I couldn't exit a certain app.

Tap to wake or unlock via fingerprint possible?

Got it a couple of hours ago and I''m wondering if there's any way round having to press the home button to unlock the phone, like being able to just rest my finger on the pad to wake it and unlock.

Any idea how to enable double tap to wake up the S7 edge? Just a new user coming from the xperia Z2.

I'd also love to know hopefully it's possible.

Nearest thing I've found so far is to enable edges then when screen is off, swipe up and down to show the edge content at which point you can unlock via fingerprint reader.

Not really, only the other way round, press the home button and leave the finger on it and it will unlock straight away.

Found this way to, but would prefer an easier one.

Well I have tried a few tap to wake apps and they all fail. This is making me think that the always on display is actually an app in its own right meaning the tap to wake apps don't activate. Any thoughts my learned colleagues?

Gotta push the button. I understand you want to just rest your finger and let it unlock (like nexus 6P) but is it really that hard to put little bit of pressure to actually push the button and just leave your finger there like you would have with a 6P? Only step you're doing is moving your finger 1/40 of an inch to actuate the button lol.

Partial success! Following this guide for the S6 edge I can have tap to wake working http://forum.xda-developers.com/galaxy-s6-edge/general/tap-to-wake-samsung-device-t3141850
The snag is, and here's the new challenge, to have either AOD or edge clock working whilst it's asleep.
@razorseal : it's not a biggie, I am just trying to recreate the functionality of Windows phones as it was a beautiful workflow that I'd like to keep of glance screen and DT2W/DT2S.
So I'm thinking it's an app like Knockr I need but one which somehow allows AOD to work. Any suggestions welcome - I'm not averse to rooting to achieve this.

Getting closer still. So I uninstalled all that stuff from the link above and put this app on: https://play.google.com/store/apps/details?id=com.orthur.always_on_display&hl=en
It has an AOD display which if you put your finger on the pad it reads the print and unlocks. It does have a double tap to wake as well which can be used to open the lock screen and then do the fingerprint.
So now I just need a double tap to sleep app then if the battery drain isn't too crazy, the mission is complete.
Anyone know a good double tap to sleep app that isn't a floating widget? Something like on CM13 whereby you double tap the status bar and it goes to sleep would be good.

You could always enable the 'Easy screen turn on' feature, which can be found by going to 'Accessibility' and then 'Dexterity and Interaction'....
I believe this was previously known as 'Air View'.
I hope this helps.

This will probably drain your battery too much. Many of these (root-less) apps keep the AMOLED screen on but with a black rectangle displayed so it looks like it's off. But don't fall into the "AMOLED black does not consume power" lie. There is an entire system powering the screen that consumes power.

Yep this is the easiest solution folks. It's what I use. Just a simple wave or swipe finger over the proximity sensor, device wakes up. There is also a setting elsewhere that stops the phone from waking up if its in your pocket or so, so good idea to use that too.

Quite a nice solution. I wonder if it has any impact on battery, since the proximity sensor is probably always-on ?
I still hate Samsung for not implementing double tap to wake. I mean, they copy everything from Apple, but they can't copy a really useful feature like this from LG (or whoever had it first without battery drain) ?

Answer to your question is Nova Launcher Pro. You can use the double tap gesture to lock the screen, no widgets required. Let me know if you have any confusion with that. The only downside with that is when I wake the phone back up, it says and I quote "Enter PIN instead of using fingerprint recognition because of security policy". It's quite a big deal for me, having to type in the PIN instead of just resting my finger on the home button. Still searching an answer for that. If anyone has found a workaround/solution, please let me know.
PS: Sorry, I had to cut the playstore link from your original message, XDA forums won't let me post with a link in it.
---------- Post added at 11:02 PM ---------- Previous post was at 10:35 PM ----------
So, I researched a bit and found a workaround. I am not allowed to post links here, so, find an app called 'Screen Lock Pro' from the Play Store. Its by a developer called Prahallad and costs $2.37. Then activate it as a device administrator, go to setting and enable 'Smart Lock and Nexus Imprint'. Then go back to your Nova Launcher settings, into 'Gestures & Inputs'. Select 'Double Tap' under gestures and select the shortcuts tab on the top. From there, select the 'Screen Lock Pro (Shortcut)' and you're done. There are a ton of other features in the app and I am still trying them all out one by one.
