Double tap on Mate 10 Pro

Hi there,
I've found this easy tweak to enable double tap to wake on Huawei/Honor devices.
https://forum.xda-developers.com/mate-8/general/enable-double-tap-to-wake-t3312676
I loved this feature on my old G4, as it was not needed to pick up the phone from a desk, etc. Unfortunately, it seems Huawei does not give a f...k and adds and removes it randomly from its products lineup depending on the weather I guess.
The above instructions are really simple on a ROOTED device. Would any candid soul that already has a rooted mate 10, try to see if the feature is at least available in the system file? (super simple to do with a root explorer). My phone is not rooted, as I'd not like to void the warranty in case I return it since I'm not fully happy so far with this and other Huawei SW neglicencies.
Cheers.

It's not working.
You can get the setting to show up but it can't be enabled/stay enabled

You mean, the option shows up in the accessibility menu, but not possible to activate right?. Shame on Huawei.
WHICH FIRMWARE ARE YOU ON?. I'm on 142 on a EU hardware.
BTW, any other reliable 3rd party up or alternative to wake up the phone without picking it up or using the power button?

I'm on B145.
They include a lot of "features" for other Huawei phones, as they seem to use the same sources when they build. Many are non-functioning though.
Face unlock with pick-up to turn on screen works fine. Or just fp reader on the back
But it still requires lifting the phone or putting your finger on the back.

Right. What a waste of such a great HW with such a poor software, lack of basic premium (?) features on a high end device.
Thanks anyway mate!

Am sure you are aware kernel must support double tap to wake in order for this switch to work, if u guys have a kernel that supports this... It will work else no way on earth that's happening

BTW, tried a few of those 3rd party apps where I managed to wake the phone up via the IR sensor from the AOD screen. But, this only works for a minute or so, if the AOD is on for longer, IR cannot wake it up.
Looks as if the app is put in a deep state or the sensor not accessible by it once the phone enters a deeper stand by (?).
All power saving crap option disabled. Wrote the developer but no response.
You guys, since you rooted it, would you know if the issue is still present when you freeze power genius via Titanium perhaps?

Problems with the fingerprint reader sensor

Hi, I have this problem with the fingerprint reader under display of my xiaomi mi 9.
When it is resting on a surface I cannot unlock it with the fingerprint, I find this very annoying especially when I am at work and the phone is resting on the desk and I would like to unlock it, or when it is on the bedside table. The only way that allows me to unlock it with the sensor under the display is to take it in hand and unlock it.
I did several tests and I noticed that it is enough to touch the metal frame with a finger to allow the phone to unlock with the fingerprint reader. Alternatively, just have the USB cable inside the door.
If it is on a surface (for example a table or a desk) it does not allow me to record the imprint because it does not even detect the finger.
I don't understand if it is a thing wanted by xiaomi or it is a problem?
I leave below a video where I show what I said.

After Global Beta 9.5.9 Update
https://forum.xda-developers.com/showpost.php?p=79507139&postcount=26
https://youtu.be/Ve6eCVPhcY0

That is really weird

I have the same problem. It is quite weird that sometimes the fingerprint is working ok, sometimes it doesn't work at all, especially when on flat surface like in your example. I think it is working better for me now, after having erased and registered fingerprints again. Also, I feel that slightly "rolling" your finger on the fingerprint is working most of the time (for example put the left side of your fingerprint on the sensor then roll it to the right side, it should work better). I am on latest Xiaomi eu rom (9.5.1) and it seems a bit better too (or maybe I just get used to it!).

My FP is good, doesn't have the problem like you said. On flat surface or anything, it's working. I'm using Xiaomi.EU Dev 9.5.1

Try to add same finger multiple times like fingerprint 1, 2 3 and 4. That's what I did and it is now better.

I'm on the last Global Beta (9.4.26) and before last EEA but the problem persist. I tried to record several times but without success. When the phone is resting on a surface it does not work. If it's in my hand it almost always works perfectly.
I can try to install the .eu and see if there are improvements.

I have the same issue on lastest EEA update. When the phone is on flat surface, the sensor barely recognizes my finger input. Im pretty sure that was working fine before the last update.

I hope this is a problem that can be solved via software with a future update. The point is that some have the same problem as me, while others work perfectly in any situation. So it is difficult to understand what is wrong.

I have the same issue. It almost never work unlocking in flat surface. The only way is to press the sensor really hard with force, then it will unlock. I have similar case in redmi 3x, the screen dramatically lose sensitivity in flat surface. I dont know what causes. Maybe it is related to electrical grounding.
Can anyone make a thread in miui bug report forum? I will support it..

Yes Mi Forum is read-only since today, they want you to use Mi Community instead, but looks more like a Facebook group than a serious forum.
For me (latest 10.2.9 Global ROM), the fingerprint when flat on a surface works just fine; but as others said before, try re-adding your fingerprints using more different and wider angles; perhaps your finger was at 0 degree when you added the fingerprint whilst in real-life practice your finger is usually at 15 degrees. Making sure you cover all the sides of your finger helps (I have 5 fingerprints for 5 fingers registered, one was responding badly, so I readded that one and it works fine ever since).
But perhaps its indeed (latest( EEA ROM related ?

Same issue with the latest Global Beta, sadly.

Hi. The problem is that seems like the fingerprint is disconnected. It doesn't react to any finger, it doesn't turn on. As soon as you pick up the phone it works flawlessly with any of the registered fingerprints.

I had the same problem on stock MIUI, with locked bootloader. Now I'm on Revolution OS and the problem seems solved, so I think it's a software issue.
Anyway when I had the problem, when the phone was on flat surfaces, I used to put my thumb on the bottom frame of the device, unlocking with the index (so using just one hand), and it worked perfectly. You can try this as a temporary workaround waiting for a software fix.

Ok, that clarifies things; I thought it was conditionally unresponsive or inaccurate, but what you describe seems like the wakelocks are too aggressively set., very typical of MIUI.
Normally one would go Settings | Battery & Performance | Power Usage, and in the top-right hamburger-menu select 'Show System Apps' and select the Lock Screen or Fingerprint / Biometric services app and disable it's 'Power Restrictions' , but MIUI hides all most internal services.
Instead, download the MiAppa and click the 'Battery optimisation' tool; then in the blue title/dropdown bar select 'All Apps' instead of the default 'Not optmised' ... now a lot of internal services and components show up. Scroll down to 'MiuiBiometric' and changes it's 'optimize' setting to 'dont optimize'. That might help with it's wakelocks being filtered. I haven't tested the setting myself - and there are a lot of other system services that might be relevant to test - so please give it a good try.
Alternatively, run a custom ROM or enable the double-tap to wake (and/or pickup to wake, but I think you already had that active), so you tap to 'wake' it, and then the fingerprint does work instantly. Internally in 'deep sleep' state it might not respond to the fingerprint directly (i.e. after a few minutes idling with screen off), whilst screen-off idle before the deep-sleep state still works fine ...

Latest 10.2.24 EEA, zero problem.
Cue the "omg omg I have a bad phone how to fix plzzz"

Thanks. I've been trying what you said without success. Doesn't matter if the screen is on (on lock screen) or off. It seems like you need to be touching and holding the device with the hand.
What is surprising me is that if I am touching with a finger the frame of the phone in the usb port zone (the only part exposed as I am using a Nillkin cover) then seems to work the fingerprint sensor.
The problem only appeared since the last update so I am pointing to software error. I've reported to Xiaomi through the app.

Have you tried unlocking with fingerprint in lockscreen (screen on)? Doesnt it different from the phone off? Mine is still same. When screen on, it should not be optimized.
Well, trick of unlocking with finger hold in side of phone seems help, but not much.
Plus add this trick, register your thumb 2 or 3 times, focus registering and unlocking in the center of thumb, not the tip. Dont use index finger. These combination of tricks really help for me unlocking in flat surface.

smart lock workaround

Is there a workaround to get smart lock to work on MI 9?
I connected my Hesh 3 Bluetooth headphones, smart lock notification pops up. Added hesh3 to trusted devices, yet the phone still locks when the headphones are connected.
Furthermore, can't find smart lock menu anywhere in settings for the life of me....

It appears that in miui roms the Google smartlock is not fully implemented. Also if you connect a device and mark it as trusted, xiaomi's smartlock only works with xiaomi devices.
Maybe in some future updates or roms it will work with other brands.

Yeah, this is really annoying, with Galaxy Note 8 I was used to have the phone unlocked when in the car... Only thing that saves this issue for me is that fingerprint sensor is under the screen so no need to take the phone out of the car holder to unlock it
Envoyé de mon MI 9 en utilisant Tapatalk

I have submited feedback, but I'm not optimistic about a fix.
also have issues with notification access with nova launcher... It reverts to OFF( although showing as active in settings) after some time..
nothing against miui. I really like it, but it is way too buggy

Agreed. Both Xiaomi and their Developers are useless morons who just want to force their own thing down people's throats.

Dumb lock
They deliberately disabled that feature, it's really annoying, can't believe no one comes up with a fix via a paid app.

Speed Up Front Camera Pop Up Speed

Hi,
Just ordered k20 pro, believe will arrive tomorrow (Using poco now)
I wonder is there a kernel that actually increase the speed of the pop up camera? So face unlock work faster? Hahaha

what update?

Face unlock is totally unnecessary or maybe I should say involves extra steps on this phone.
1) Its software based so can be unlocked with facial similarities.
2) you have to actually turn on the device & swipe up to activate the pop-up.
Thus fingerprint is much faster & efficient to use as it's already always on

1) Yes and fingerprint while having way less chance of that is prone to similarities as well
2) That is bad, in my opinion it should automatically pop up when activated via button on the side or tapping on a notification on the lockscreen
About faster and more efficient... The fingerprint scanner is too low to be comfortable and i prefer to press the button on the side and comfortably swipe up than try to reach the fingerprint sensor.
I really wish that whole under screen sensors while cool concept would move back to what Sony did with fingerprint sensor on the side so you unlock when you just grab the phone.

think what would happen, if you where to press a button accidentally and the cam popped up in your pocket...

Touchscreen issues

Hi there, I bought a Xiaomi Mi 9T Pro 6/128 recently. I instantly noticed that if I'm using full screen gestures I have some troubles doing WhatsApp audio recordings. Single press is recognized on the bottom corners, but if I do a long press, my system doesn't recognize it.
I thought it was a gesture's "feature", but I have investigated a little and I found an issue in that part of display, even with gesture disabled (so, using softkeys).
I didn't find anything about this issue, but it's very annoying because I am not able to do WhatsApp recordings, because long press on recording button isn't recognized at all.
I also uploaded a video in which I show the issue
Tell me if you have the same problem, or if there are any solutions.
Single press works ok in the bottom corner, but long press isn't recognized
Link to the video:
https://youtu.be/cSIi8m2WwyA

I can confirm that same issue is present on my phone. But I would say its rather a bug with MIUI/Whatsapp as I can confirm that touch is working perfectly on that part of the display in CIT or Other apps.

Try it. A single press would work very well, but long press on the same area won't be recognized
You can check it with any app that lets you draw/test touchscreen

I've noticed this on my device too. Is it a hardware or a software issue, if its software issue can anyone confirm if this issue exist on custom roms too.

I'm using a custom ROM since April (EvoX) and I can confirm you that the issue still persists. Don't know if it's vendor related, or it is an hardware issue.
The only good thing is that with Android 10 and gesture bar (on miui 12 and custom ROM also), it's easier to record voice messages since gesture bar takes 1-2 mm of the corner, so less "defected" space for touchscreen
