knock on feature missing after root?? - Xperia Z2 Q&A, Help & Troubleshooting

updated my phone to latest stock with root following the guide on here and went smoothly however it seem the knock on feature is the only thing that doesnt work or seem to be missing..

Do a factory reset and see if it works after that.

Nope didn't work.

Reflash the firmware, that will help for sure.

I think he means double tap to wake. The option defiinitely works on rooted firmware. I'm on 23.0.1.A.0.167 (rooted myself using PRFCreator) and everything's working fine. Go to Settings>display settings and make sure the option is activated. Oh and when you double-tap, it has to be done quicky and your finger must touch the same spot twice.

You're welcome. Always glad to help.

[Q] Android 2.1, no lock screen??

Hey guys,
yesterday i flashed my X10 to the nordic 2.1 FW, rooted it and cleaned it up. Everything looks fine, but when i press the on/off button the phone online turns off the screen, but is still unlocked
When i push the button again i come back to my homescreen and not to the lock screen
Any suggestions?
Flash again
it's not a bug, it's a feature!
How did you do that? Don't want Lock Screen

You don't, must be a bug. Reflash or repair.

Find No Lock application on market. It handles that. Keep in mind that it must be running to work.

But it's not a feature of the 2.1 FW, and as the OP hasn't mentioned any apps it's more than likely a bug.

[D6502] Trouble waking via double-tap when a message is waiting

I am using the 'double-tap to wake' functionality and I like it very much. But when a message from WhatsApp is waiting for me, double-tapping the screen does not wake up the phone. I need to use the Power button.
I am using the latest firmware (17.1.2.A.0.314), rooted with locked bootloader. I am using Xposed w/GravityBox and Greenify.
Can someone confirm?
I am not using whattsap but i can say the double tap is somehow weird on this fw
So far the experience for me is always hit and miss. If the phone is deep sleep (meaning it wasn't used for a while) then most of the time I have to use power button to wake it up.
Yes exactly, and i think it was working better on the. 402 fw

For me it's almost the same behaviour throughout any firmwares.
Yep, same here on 402...

Fingerprint Scanner Problem in 6.0 MM

Hi guys!
I really love this phone, but I have a really, really, really annoying bug. I have only 2 days with this phone (MM updated since the first day). When I try to unlock with my finger it works most of the time, but in some occasions it ask me for the knock code or the pin directly, giving me no chance to use my fingerprint to unlock the phone. This is really annoying because I want to use the fingerprint sensor to unlock the phone and it does not let me. Does anyone have the same problem with the V10? Any ideas for a possible solution? Thanks a lot!

We have this problem too and assume you are using a third party launcher (Nova, Google, etc). Switch back to LG stock launcher and it fixes the problem. Think it has something to do with the lockscreen permission changes from Lollipop to Marshmallow.

I'm actually using Nova. I will switch back to LG Stock Launcher (uggly, by the way), and I'll tell you if it worked or not for me. I'm thinking on the same about te permissions in MM. There is no way to upgrade permissions from the settings or something like that to keep using a third party launcher?
Thanks a lot for the help!

Did you ever find a resolution to this. It's pretty annoying but i'm not willing to give up Nova

I ran with LG's launcher for the past couple of weeks and since the recent beta updates to Nova shows no sign of a solution, I've reverted back to Nova and just switched to pattern unlock for the time being.
You know, even using nova, you can double tap the notification bar to turn off, and still use the fingerprint to unlock.

^ Incase anyone of you missed it, the finger print scanner works if you double tap the notification on Nova Launcher to lock the screen.

Try to factory reset, or change the unlock method to a different one, and then go back to fingerprint.
already did.factory reset by lg bridge..hmmmm
. i do hope its only a s/w issue. huhuhu
may due to mainboard problem
i also met this problem.
after restart, restore or refresh kdz, nothing changed...
my model is LG V10 H961N

Speak for yourself. :laugh:
I'm on MM on my H960A AND I'm using Nova Launcher since the first day. Never had this issue. I only had a problem once after unlocking the bootloader. You have to enable "OEM unlock" in the developer settings prior to unlocking the bootloader and I did not disable that option again afterwards. The fingerprint sensor did not work at all with this setting enabled. You can register new fingerprints but unlock does not work.
Since I disabled this option I have no issues with Nova and fingerprint. Should you have unlocked your bootloader as well make sure you disable "OEM unlock" again.
I'm on MM and using Nova prime but I don't have any problems with the Fingerscanner!

Hi!
I have this phone for 4 days and i had the same problem like you,
I use to lock my screen with third party applications like:
Greenify or Screen Off and Lock
And for this i have the same problem like you,
If you had the third party application for locking your phone, you can uninstall them or lock your screen by double top or power button.
Good Lock!

Try this...
I've had this problem also. It seems to have started after a security update from T-Mobile.
Try this fix and let me know how it works for you:
Follow these steps:
1)Goto settings -> fingerprint & security -> fingerprints -> then delete all fingerprints
2)Then goto apps -> switch to show system apps(im using 6.0) -> find com.lge.fingerprints then remove data and cache memory.
3)Goto storage & usb -> clear cached data
4) Then restart your V10
5) After that, add fingerprints in fingerprint lock then it detects your finger.
If it doesn’t detect your finger, repeat the steps.

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?
Well bro you can use the "Evie Launcher", than go to settings and pick double Tap option. You can lock your phone via Double Tap than (Not unlocking)

Double tap to wake stop working after factory reset

Hello, can anyone guide me how to fix it without rooting? So double tap to wake is not working after a factory reset, Double tap to sleep on lock screen works tho. I did a factory reset because of heavy ghost touch issues.
Probably a settings issue.
Or simple load the app Double tap, it's likely is better than the stock app.

Double Tap is a near perfect app. I use instead of the Samsung one as it has more and better features to dial it in. No downside, stable.
