Problem in double tap turn-on - Xperia Z2 Q&A, Help & Troubleshooting

Hello guys, I have a little problem with my Xperia Z2. When I do double tab on screen sometimes my Xperia Z2 don't turn-on.
Alsome know as fix this?
I am with Rom eXistenz, but when I was with Rom stock, also had this problem.
I'm sorry, I'm Brazilian and my English don't is good.
Thanks

This is a issue you have to tap on the same area where u did the first tap and it will unlock

I don't really use this feature anymore as for me, it only worked "properly" on 4.4 and since then I find it very unreliable to the point where there's no benefit of using it as taping 3-6 times on screen just to get it right isn't very convenient. It's really shame, since back in time of 4.4 I've pretty much used tap to wake exclusively. Not sure if there is any fix/sensitivity change... Would be nice though

You can use an app called ambient display when u pull your phone out of your pocket it will unlock by itself.must try that

Thanks for all answers.

[Q] Touchless control or DT2W?

Hello! My name is Alejandro. I had a Moto X but you can't have nice things here in México and some nights ago i got robbed and bought a second-hand xperia P but i really miss OK google and active display.
Now i know OK google can be used with open mic and apps like that but this phone's battery life is awful and i can't even imagine how worse it would get with an always listening mic. And Active Display won't install in a non-moto device (even some moto G users can't get it to work) but i think i've seen double tap 2 wake in some kernels but they also drain the battery pretty quickly.
So here's the question (and i really don't know anything about programming besides HTML and a little java so forgive me if i'm asking something stupid): is it possible for developers to add Double tap 2 wake and OpenMic or some feature like that but somehow only trigger these functions when the phone's charging? Like:
Phone Charging (is it possible to make this also for deepsleep but ONLY when the charger's plugged?):
-Always listening microphone
-Double tap 2 wake
Phone running on battery:
-Normal stuff that a kernel should do while on battery lol (maybe a little underclock for those of us who don't really use much the phone for games)
I know this is my first post and i'm sorry if i'm being annoying but tell me, is this possible? how viable is it?
Thank you all for reading, good luck if you try to do it :good:
Double tap 2 wake is a kernel thing. The other things you want can be done through tasker app

Fingerprint unlock loads random app

Hi all
I'm very satisfied with my S6 Edge (925F) but I'm facing a weird problem: when I unlock the phone using my fingerprint(s), it works perfectly but sometimes it's not the home screen which is displayed, but another random app, (i.e Facebook, Settings, News Republic or other...)
I have to press the back button to return to the home screen...
Anyone having the same problem? (not a big deal but...)
Started to happen to me as well a couple of days back. It's strange because it never happened before and I didn't change anything on the phone.
Never happened to me so far. Are you sure you weren't already in that app when you locked your device? The fingerprint unlocks into the last open app. Go back to home before locking.
Another possibility is that you are tapping a notification before unlocking. Say you have a notification from FB and you tap on it. The screen will stay locked, but it will open the FB app. Unlocking with fingerprints will then show FB open. Same can happen for email, texts, etc. You can also pull down the status bar and tap settings, then when you unlock, settings will be open.

Thanks but not at all.
It happens randomly, either I'm in an app or not (and if so, it's not necesseraly the one I was on!)
Quite mysterious...
I was using Nova Launcher (maybe the cause), will give 2-3 days Touchwiz a chance, and will report back...
Hey guys,
same problem for me. It is not dependant of the unlock method (i'm experiencing it with finger print or regular unlock).
I think it is a Nova launcher bug, only occur with nova for me.

I think so...unfortunately...
I think it's the latest nova launcher beta version that causes the issue.
I'm using Nova since I got the phone, a month ago, haven't experienced this.
I have been having this problem too and was about to start a new thread. I am using Nova too, though I did try installing the google now launcher and seemed to have the same problem. I suppose Nova simply being installed may cause the problem.
I will try uninstalling Nova and use TouchWiz for a bit. Not sure how long I will last, I think I prefer the random apps to Touchwiz.
How did the rest of you get on after switching away from Nova?
I have been experiencing this issue as well but ive been using the nokia Z-launcher. I have a feeling it might also be my fingers inadvertently touching the curved portion of the screen when i hold it.
I have the same thing happen to me. I thought I was going insane. The worst part is, I'm on a note 3 and I'm using touchwiz lollipop. I'm 100% sure no applications are running before I lock the phone, and when I use the pattern unlock, whatever application shortcut that was on the screen when I lock the phone, a random app from that screen will run when I unlock the phone. It doesnt happen all the time, but it happens at least a couple times a day.
Reason
Hey guys. I am using Nova Launcher too. And I have the same problem. I don't have the sollution, but I found the reason. ? When you lock your S6, the touchscreen stays for a second active. And if you hit an app in that second it will open when you unlock your S6.
Sorry for my bad English, I hope someone can do something with this information.
Cya ??

It seems that if the Nova's desktop margin is set to "Medium" or "Big", this problem is reduced, but I don't know if it's fully solved. Will see...
Have you found any other solution?

I think that has nothing to do with it. It could be true that it reduces it, but the only reason it would do that is because:
Mostly when you lock your S6 your fingers touch the side of the screen.
When you set margin to "Medium" or "Big" and you lock your phone, your fingers wil most likely touch no app on the side of your desktop, because the margin "pushes" them to the middle of the screen.
I haven't found a solution. Still waiting for an update to fix it.

Yes, that makes sense. Anyway, if looks perfectly good with marging set to medium, and I've had no issues with this problem since I changed the setting (yesterday). So if it reduces the problem so much, I can live with it...

Other ways to wake Xperia XA Ultra

Hi guys!
As the thread title says, are there other ways to wake the phone up other than the power button?
I understand that some devices can have the phone screen turned on through other means, like the volume rocker or maybe the camera button (needs root on some), or maybe even through a flip cover magnet.
The goal is to prolong the life of the power button, so any help would be appreciated.
TIA
I guess I'm stuck without root, right?
I use a flip cover. There's a reed switch in the phone that will turn the screen off if a magnet is near and turn the screen on when the magnet leaves. The sweet spot for the magnet is about a finger width away from the volume rocker. I can send you a more accurate position if you need it.
Prior to that I was using an app called Gravity Screen. It's on google play app store and it worked pretty well if you discipline yourself to put the phone screen down. I used it to turn the screen off if I placed it face down on a desk or if I put the phone in my pocket. There are settings for using the phone with headphones attached and having it in your pocket. You have to play with the configurations somewhat but it's decent.
There are similar apps in the store but that was the one I bought.
Lastly, it's only half a solution but the xperia home beta lets you knock the screen twice to turn it off. If only it would let you knock it back on then life would be good but things are never that easy.

Thanks for the tips!
I currently use Greenify to have the screen off and sleep as a workaround.
I'll look into xperia home beta, maybe it could work better..
I also have a flip cover, though it doesn't have a magnet on it. Maybe some quick hacking could work, too, but I'm not sure if the magnet could fit flush in the case.
Gravity Screen is another one that I can look into. I'll see how it could work for me.
Again, thanks for the help!
i use nova launcher prime with the double tap gesture to turn off the screen it works really well but as turning on the screen i havent found any app that doesnt consume so much battery lets just hope that nougat bring such feature, the last couple of days xperia companion warn me about an update but when i tried to download it nothing happened so y we have to wait some more i guess

I've used that feature on Nova for all my other phones. That, configured to work with Greenify's Lock+Sleep feature works wonders.
For my Xperia, I'd like for it to be with Xperia Home, just have to check with Xperia Home Beta to see how it works..
I was just a bit curious to see if somebody with XA Ultra without root has remapped a key to another button to wake the phone up, as somebody was able to change screen density without root.
Anyways, I guess a smart cover may be the only practical workaround for this.
Thanks for your feedback guys!
Xperia home in fact has a double tap to sleep functionality..now, if I can only map it to use Greenify's Screen Lock + Sleep functionality..
So, double tap to lock has a workaround, but it would have been great if we can enable double tap to wake (i know its a kernel feature - impossible to mod unless we have root + custom kernel) or maybe even just map the volume or camera buttons to do it..
I wake my XAU with my Sony SmartWatch 2. I hope they add dtw when Android N is released. Gravity Screen works well but drains battery a bit quicker.

Nice! I actually am thinking of getting a Smartwatch, but it's kind of hard to justify the costs..
Yes, I have used Gravity Screen years ago, and it does drain the battery quicker than without..
So, not unless we have root, i think those are the only options we have for XAU

RROS even has a setting to enable that but it didn't do anything for me either. I think that's just not possible on the Honor 9... Sadly - would have loved to have that feature too.

The fps always goes straight into the homescreen and I often just want to see my notifications on the lockscreen. Having to press the power button on the side therefore can be quite inconvenient when the phone is lying on the desk.
PS: Oh, well, that was another downside of EMUI. I don't get why they don't show older notifications on the lockscreen. If the phone gets unlocked once, all the notifications for this moment don't show up on the lockscreen anymore (which stock Android and I guess most other OEM skins do).

Strange that it is missing as it works in the H7.
Isn't that a hardware limitation at least on the h9?

Mate 10 Pro Double tap to wake

Hi Everyone,
Why Huawei didn't activate this function to their high end phone. THIS IS VERY USEFUL.
Anyone, manage to activate this on their rooted mate 10 pro?
Think you posted in the wrong section, only way is to install nova launcher as it works with this

No, nova launcher has no double tap to wake. It has only double tap to sleep. I think you are wrong. If there is, pls guide me and appreciate it much.

Some weeks ago someone hinted at some code in the firmware which was supposed to handle double tap to wake. But there's no confirmation anywhere that Huawei will ever enable or further develop that code, just assumptions.
in Mate 8 forum there is a thread about enabling double tap to wake through some modifications on build prop.
That requires Root but I have no idea if that procedure could be implemented on mate 10

Yes, the sensor is good, but kind of difficult to access while phone is mounted in a car - double tap to wake would be nice then, I miss it from my OnePlus X.
hello to all.... is possible that even in march update official, for huawei mate pro, is not present double tap to wake? other alternatives drain many battery... i hope a solution in last 4 monthes in this post
my solution
Hello,
As a former LG G2 user I've quickly begun to miss the double tap to wake/sleep | knockon/off function with my Huawei Mate 10 Pro. So after lots of investigations and app trials here's my solution which seems to perform pretty well in my opinion.
After trying many apps I've encountered the so called 'Always on AMOLED | Edge lighting'.
Here's my setup on the mate 10 pro (emui 8.0.0, android 8.0.0, build 8.0.0.157 C432) first:
1) Disable smart cover
2) Disable pick to wake
3) Disable pulse light (it won't work and we'll use app's notification handling which is great in my opinion)
4) Disable always on display information
5) After installing the app (VERY IMPORTANT!):
- Go to ignore battery optimisation in android's settings and add this app to the Allowed list
- Go to battery / launch - then Manage manually the amoled app:
* set to on - auto launch
* set to on - secondary launch
* set to on - run in background
To quickly find the upper settings use the search bar in the settings menu.
Then in the app (v. 2.1.7 tested):
1) I've made a fully black background instead of a clock - upto your flavor
2) Enable the POCKET MODE! This actually saves battery a lot since if proximity sensor is covered the screen is completely shut down. When you sleep/want to save battery place the phone with face down - sounds as no problem to me..
3) Brightness is set to 10 or so - again upto you, the less the better for the battery
For double tap to lock I use a widget placed all over the screens where there are no icons - sounds annoying but once settled it works flawlessly. Here's the widget I use - DTS widget Skynet Software.
To be honest I've found it from this forum.
Share your experience as I might have missed something.
P.S Somehow the power button won't lock the screen now but I don't use it at all anyway, so no problem to me..
P.S.2 I would have bought another LG phone if only they have kept the IR Blaster but that's another story..

Same, I only like double-tap to wake on my phones without fingerprint sensors. On my mate 10 and Xiaomis, whether front or back, I am prone to using the fingerprint sensors, and they bypass the lock screen too.
Of course, it's a nice feature to have that doesn't drain battery, all my phones, except Huawei, have dt2w.
