Possible fingerprint scanner mode? - Sony Xperia X Questions & Answers

I find my Xperia X still very useful, I'm currently using another phone as my daily phone but I still use my XX to record audios from my practices (I'm musician) and video, because the quality is better than my daily phone's.
However, what got me tired was the fingerprint scanner. It's very inaccurate and fails to unlock the phone almost every time, and I find this very frustrating. I don't know if this happens because I have fat thumbs (LOL), the phone has some defect or there's a problem with the fingerprint/power button. Does anyone else have the some problem?
My real question is: may be possible to remap the power button so it acts only as a fingerprint scanner? Considering that we practically don't need a power button to turn the screen on... My current daily phone is a Honor 8, and I just love the fingerprint scanner in the back, which I use 98% of the time for turning it on and unlocking it at the same time. The thing is that the fingerprint scanner and the power button are not tied as in the XX. I think remaping the power button to act as a fingerprint scanner would give me more chances to try to unlock it before disabling the scanner after many attempts, because the screen would be actually off and it wouldn't be necessary to press the button everytime, it'd be only needed to put my finger on it.
It sounds really complicated I know, but if there's any chance, please tell me. Or, do you think ROMs like AOSP or Cyanogenmod would do this? I'd like to think so, but ufortunately I see poor development for the XX

[Q] SK17i keyboard malfunction

There's a problem with the keyboard of my girlfriend's SK17i and I don't know whether it is a software or hardware problem.
The problem in question is a over-sensitive key, in which for this case, it's the "f" key. Whenever she uses the pop out keyboard, the "f" key seems to be jammed and it would infest any of my messages with a bombardment of "f"'s, making it extremely irritating to use. It's gotten to the point where she don't actually have to press down on the key, all she has to do is slide her finger across it and it would register on multiple occasions. In addition, it would also register if she were to press the other keys around the "f" key, rendering the keyboard almost completely useless.
Furthermore, the extent of the problem actually affects the phone whilst the screen is off; at times, she would wake up in the morning and if she was on whatsapp, the messaging bar would be full of "f"'s and if she was on the homescreen instead, the phone would automatically open up the browser and the search bar would also be full of "f"'s. Moreover, it also affects the on screen keyboard, albeit not as much but at times, the phone would seem to be registering "f"'s as it thinks that the pop out keyboard is in use. Therefore, the on screen keyboard is also becoming highly irritating to use.
I don't know how to fix this and it seems the more likely to be a hardware problem but if anyone seems to have this problem and was able to fix it through a software solution, please let me know as she loves this phone and she don't want to get rid of it! Thanks in advance!
Does the button itself still behave correctly, like you can press it?
It seems more like hardware failure to me.
About those f's, doesn't lockscreen prevent that from happening, while screen is off?
She can still press down the key and it clicks which means that it works and isn't jammed.
As for the lockscreen situation, she didn't actually press down the lock button because she assumes that once the screen goes black, it automatically locks and it does on any android phone. Maybe the "f" key is stopping it from actually self locking.
Also, she says that whenever she presses down on any other key, it has a bit of resistance but on the "f" key, it feels flimsy. We both assume that it is a hardware problem but we just wanted a second opinion.
Thanks in advance!
If it feels "flimsy" then it doesn't behave correctly, IMHO.
Have you tried resetting the phone to factory defaults? If not, give that a try (backup first!), although I doubt it will make any difference.

Exactly. That part blocks it from locking.
It does seem a hardware problem, because there is no such thing as button sensitivity. What I mean, is that key is damaged and is touching the sensor(a small button on chip likely).
If you still have warranty, take it back to shop.
Thanks for the advice! She'll take it back to the seller with the warranty (bought it online with 12 month warranty)

Fingerprint sensor/ Lockscreen

Hello,
Long time lurker here and was hoping for some advice/ suggestions.
I have a Canadian S9 Plus (on Bell Mobility) and noticed the following issues/ annoyances:
1) When the phone is woken up (e.g. pressing the virtual home button, plugged into charger, new text message received, etc.), the screen would turn on, continuously look for fingerprints ("Wipe the fingerprint sensor and try again" message would keep flashing) and would not shut off until I press the power button to turn off the screen
2) The fingerprint sensor generally works (e.g. unlocks the phone, swipes to drop down notification window), HOWEVER it does not work to unlock the phone if the phone has been sleeping for more than a few minutes (nothing happens no matter which direction I swipe/ press the fingerprint sensor). When I try to unlock the phone, I will have to press the power button to wake up the phone then swipe the fingerprint sensor. This may be a standard feature, but after pressing the power button to wake up the screen I will always get a message that says "The fingerprint sensor may be dirty. Clean it and try again.". Again the fingerprint sensor otherwise works so cleanliness of the sensor isn't really an issue here.
Has this happened to anyone's phone? I tried clearing cache/ resetting app preferences/ factory resetting the phone multiple times but with no luck. I also called Samsung but the conversation didn't go anywhere.
Any other suggestions? Thanks in advance for your help!
Have not had that issue with mine.

Tried both finger gesture on and off - no difference with the same issues persisting :crying:
this is the exact issue im facing when i got my s9+, i also thought that it was a factory defect. but luckily recently it didnt came up again and i did nothing. but still continuing monitoring the issue as it is really so bothersome.
Sounds like a defect to me. I'd exchange it.
I have not had any issues. Have you tried re-scanning your fingers? I noticed that this finger print scanner is different from the one on my LG V20. It feels different, and seems to operate different. It's also a little smaller which makes me have to position my fingers different.
I also read the instructions wrong.. I was supposed to swipe my finger during the setup. I was pressing it down. Either way mine works great.
Same issue here, did you manage to solve it?

Not at all - I ended up returning it. Any luck on your end?
Maybe try registering your finger/s with and without a case on. See what happens.
Same issue here. This is the one thing that really bugs me about this phone.

fingerprint scanner not working after long time idle

I am experiencing lately an odd bug.
If I leave my s9 plus for some time without messing with it, the fingerprint scanner is not responding. Ofcourse I can just press the power button to open the screen and then the fingerprint scanner works great as it should. I can try to unlock the phone many times after that, and it will work as it should.
This only happens once if I leave the phone idle for a long time.
Anyone else with the same issue? Is there any possibility that the fingerprint scanner is getting into sleep mode...?
Yes i'm having this problem with lg v30 Havoc rom.. fingerprint stop working after idle..

Smart wake mod/app for GSI?

The stock ROM of my Moto G6 Play had a feature where if you'd pick it up it'd wake up automatically. I think it worked with the accelerometer.
On the Blackberry Leap I had before that you could just swipe up on the screen when it's off and it'd unlock.
For the past years I've been running GSI ROMs on it, where it seems you have to press the physical power button or use the fingerprint sensor to wake the phone up.
However, both the power button and fingerprint sensor are getting more and more broken over time.
So it would be... very convenient to have a more convenient method to wake the phone.
Is there anything that works on a GSI ROM without Google services?
I found WaveUp on F-Droid, but it works very poorly on my device, unlocking only after excessive waving for a good while.

General Why must unlocking my phone be so cumbersome?

The simple user experience of unlocking the device on is so bad on Pixel 6. There's just no winning option.
Smart Lock randomly kicks in, so I can't be sure that a single tap of the screen will turn on the phone.
The fingerprint sensor sucks, and requires a tap on the screen just to bring it up. And sometimes I don't even get the option to use my fingerprint.
I don't even like the single-tap gesture to begin with. It means I'm accidentally turning my screen on all the time just when carrying the phone. It almost started a call with my deadbeat father, who I haven't talked to in 20 years
I could go with no screen lock but then I'm locked out of several key features (like viewing my account passwords). Also, pressing the Power button at all on a phone this big is cumbersome, since I then have to reposition my entire hand to go from pressing it to then interacting with the screen.
I'm already rooted because I absolutely needed the Back button to be on the right side. Now I'm hoping modders can fix the unlocking experience because it's the next big issue in my mind.
The fingerprint scanner is actually very good if you set it up right, and will always be displayed with always on display... No tap required. Problem solved

This is not my experience at all. Sometimes I get a fingerprint sensor icon. Other times my phone is unlocked via Smart Lock and I get an Unlock icon in place of the fingerprint sensor. Other times I get a Lock icon indicating Smart Lock is expired. Other times I get no icon there at all.
If the fingerprint sensor is there and I'm on the dimmed screen, sometimes it'll just light up and deny, and other times it won't even acknowledge that I've put my finger on the sensor.
If the Unlock icon is there, it requires a tap to unlock (no holding!). So that means I have to actually look at the screen and discern which icon is there to know whether I need to tap or hold.
And Lift to Check Phone would be even more problematic for me, since I'm trying to avoid accidental screen interactions and this would only cause more.
On all my other Pixel phones I just touch the back fingerprint sensor and the phone is on. I don't have to think about a dozen different possible states the phone could be in every time I want to turn it on.
Have you tried to recalibrate it via the Pixel tool thing Google has?

It sounds like smartlock working as intended (which I find useless, and poor security). It will give you an unlock icon instead of the fingerprint. Maybe you simply don't want smart unlock, which is more useful for password only. This seems like more of a matter of figuring out what features you want to use.
If you changed the Animation Scale in Developer Settings then the AOD fingerprint icon can disappear.

I never used to use Smart Lock, but on this phone it means I don't have to deal with the inconsistent fingerprint sensor as often.

Try setting up the fingerprint scanner again, slightly moving your finger with ever press during set up to get every angle and view of the print. It's been pretty much perfect for me. I suppose Google could have helped instruct people to do that better in the process.

I just restarted my phone, and then repeatedly unlocked and locked it (sometimes by fingerprint, sometimes by tapping). By the end of the video, the fingerprint sensor icon disappeared completely and wouldn't come back until after another restart:

This is just one example of the inconsistencies. I haven't changed the animation settings either.
I did see it happen a couple of times in your stream. I don't recall seeing that on mine, but I haven't been looking for it. The only other thing I can suggest is make sure you have the latest updates and/or factory reset.
Edit - I tried to replicate your stream, and the sensor showed in all 30 attempts for me. For whatever it's worth, so might be something specific to your device, maybe settings or software issue

It could be a bug related to my specific settings:
Rooted device, still on the October update
Lock after screen timeout: 30 minutes
Power button locks instantly: Off

what are you going on about lol. this is the kind of nonsense that is so irritating. you had 100% success rate unlocking your phone. what's the problem. looks to me like it works. so what's the big deal. and then you have the gall to complain that the sensor icon disappeared after you repeatedly locked and unlocked your phone? yea. try starting your car repeatedly. see what happens with the engine.

Yes, I know and I hate it. It's extra motion that tires out my hand and I often trigger the gestures when I don't mean to.

i will just apologize and go on with my day. good luck with the phone.
I went ahead and updated to the November firmware, and wiped my data as well. Now my phone won't show the fingerprint sensor while unlocking under any circumstances. I also found an interesting bug wherein I'm still able to turn my screen on by tapping it repeatedly even with "Tap to check phone" disabled:
screen-20211102-164842[1]
Watch "screen-20211102-164842[1]" on Streamable.

EDIT: And, of course, as I was typing this the fingerprint sensor just magically came back. And it still doesn't work unless I tap the dimmed screen to wake it first. Watch as it straight up ignores my finger the first time:

I can recreate this 100% of the time by just setting my phone down for a second and picking it back up, then trying to unlock it. And you can't see it in the video, but the sensor doesn't even light up the first time I touch it. This is clearly a software bug.

Guess you don't know anything about cars. You can start and stop a fuel injected car until the battery dies, and nothing will happen to the engine or fuel system. (Yes, the battery will die if you keep starting the car and tuning it off right away) Just as proof of this, most modern cars shut off the engine when you come to a stop, and restart when you let off the brake. If you're in stop and go traffic, the engine will shut off and turn on repeatedly in a short amount of time nd distance.
Now with classic cars and motorcycles, you my flood the carb with repeated starts. Not a big deal, and not any kind of damage.
The only "damage" in repeatedly starting a car would be normal wear and tear on the starter. They do have a finite lifespan. But again, not damage, just use.
