Tactile assist for finding fingerprint scanner - Samsung Galaxy S20 / S20+ / S20 Ultra Questions &

I'm new to in-screen fingerprint scanners. I've had this S20 for less than one week and miss the back of the phone scanner of my previous phone. Maybe in time I'll be able to reliably find the scanner without looking at the screen. Do long time users of this sensor eventually develop muscle memory to reliably find the it?
I've found a flawed, low tech method to unlock the phone without looking at the screen. I put a small piece of clear tape on the screen centered on the fingerprint scanner, see attached photo.
After finding the tape with my thumb I need to lift my thumb and put it right back down. I was having a high rate of success unlocking the screen this way. Unfortunately putting the phone in my pocket rubbed off the tape. I cleaned the screen protector (factory installed one) and reapplied the tape but it still came off in my pocket.
Just having the tape there for about 30 minutes of unlocking seemed to help train my thumb. Even after losing the tape I had about a 60% success rate in unlocking the screen without looking at it. I wouldn't call 60% acceptable but it's better than I was achieving before.
Maybe someone has a suggestion for a better method? Better tape? A small drop of super glue or some other adhesive? Maybe use this tape method short term to train my thumb to find the sensor? Something else? Maybe someone will eventually develop a screen protector with a subtle dimple or divot.

Another Shattered display....a few general questions

So, For the first time in my phone career, I have dropped and cracked a phone. I decided to go the route of trying to replace only the glass. There are multiple videos out there, but very few are specific enough for my liking. Let me start by showing what I ordered. It will be here Tue,
So here is the replacement part i ordered.... http://www.amazon.com/gp/product/B00A66UH8I/ref=oh_details_o02_s00_i00?ie=UTF8&psc=1
And to avoid having to use and cut double sided tape, I went with this...but I'm not convinced that it is what i need. I could use some opinions on this. http://www.amazon.com/gp/product/B00BMD8HMM/ref=oh_details_o01_s00_i00?ie=UTF8&psc=1
Its very limited on description, but i think it is basically precut double sided tape for my project.
So, I am going to remove the rear housing but leave the motherboard in place for this excursion. Using a heat gun and the tool provided with the part, I plan to remove the glass from the digitizer.
My screen is completely shattered, so I feel like that may help me a little bit. I can use tweezers to remove the larger bits instead of having to worry about removing the whole screen and putting too much pressure on the screen.
What do you guys think?
I think you have a good chance of success. ...if...
The temperature of the gun is correct.
I've changed 2 screens, and I will not do it again.
The trick is heat and being patient in the repair.
You'll get it. ..just don't rush it. ...g
Edit:
Use a vacuum cleaner with a small piece of tubing taped into the hose end to provide suction in getting any glass pieces you can't see while the repair is under way. ...g

I do this for a living. Be incredibly careful when you do it. I recommend that you pickup a non-contact IR temperature probe, the reason you'll want this is so you don't overheat the LCD and yellow it. Keep the temperature of the glass below 200°F at all times, any higher and you start to run the risk of yellowing the LCD. The adhesive that will remain behind is relatively easy to clean off, just be patient with it and take your time, you can get a clean repair by doing it slowly. As for the adhesive, it's not very easy to not have bubbles, but think of it like installing a screen protector and you should be fine.
One great tool to have for this (and other hot air work) is a thermal camera. If you can get your hands on one great. Be sure to set the pallete to custom and pick colors that will get your attention when they get too high. Set the thing up on a small tripod or something so you can see your work in it and easily monitor the image. I have one where I work but would think of renting one if I did not have access to one and planned such a temperature sensitive job.

[Q] Disable proximity sensing for double tap unlocking?

Is there a way to TEMPORARILY disable the proximity sensing of the double-tap wake feature of LG G3?
What I want is to be able to wake the phone and unlock it while the phone is in a transparent case (waterproof bike mount, armband, etc.). The phone currently thinks that it is in the pocket and does not wake on double-tap on the screen.
The power button is in the center of the back of the phone which makes it hard/impossible to reach/find when in such a case/armband.
Is there a hidden setting or an app that will make this possible? And once more - I need this for temporary situations when riding a bike. After riding a bike i'd like to re-enable the proximity sensing for pocket carrying.

Cut out a small hole in the plastic right where the sensor is. That's how I solved the same problem.

"waterproof bike mount" :good:
Automaton locker might have a setting that will help you.

The OP has probably solved his problem in the meantime. I had much the same issue, and I wanted to share what I did.
Firstly, yes, there is a way to "disable" the proximity sensor: just cover it with something that a) does not emit, and b) does not reflect IR light. Because of a), a finger does not work, but a piece of black sticky tape does. If only the right of the two little lenses is covered (that is the IR LED), the ambient light sensor even continues to work.
Of course, putting on some sticky tape whenever I use my G3 in the bicycle-mounted case is not the ideal solution. So I experimented with sticking the tape to the inside of the case. That did not work too well, because the front of the case is flexible and never lies flush on zthe screen. I ended up putting some thicker, spongy rubber there.
All this was with Rixen & Kaul's Phonebag M, which otherwise worked very nicely and allowed me to use my previous phone for navigation even in the most torrential rain.
But that spongy rubber blob made the touchscreen more difficult to use, as it lifted the case's transparent front even further away from the screen. So I kept looking, and bought Topeak's new Drybag 6.
It's a bit too big for an L3, but the Drybag 5 seems to *just* be too small - you'd probably get an L3 in there, but not out again. So the size 6 is the better choice. The interesting thing is that Topeak seems to use a different material for the transparent front: it seems to reflect IR light a lot less than the Phonebag's, so I can switch on my L3 almost every time (I'd say, 95% of my attempts worked). I will keep testing it for a few more weeks.
Two other things I find nice about it: the bicycle mount doubles as a belt clip, and it has a ziplock-style - um - ziplock, so it's probably not just resisting rain and sweat, but really waterproof. When I closed the ziplock, it was air-tight.
What I don't really like about it is the flimsiness of the mount - even the screw is plastic, and the case has a lot of play in the mount. I don't think, though, that it can fall out, even on bad roads.
Hope I could help someone.
Cheers

I need help removing Nexus 5X screen

Hello guys,
I had an accident where I spilled liquid on top of my phone's screen, it was alcohol based, so it got through the bottom speaker and went to the screen layers. After a couple of days of trying to dry it out, there are still terrible looking streaks that look like water damage. I tried using a hair dryer and a suction tool from my car mount for the phone, to remove the screen, but it won't budge. This method worked easy with my old Nexus 5. Some heat, I pull up and it comes right off. With this - I heated as much as I can, and then pulled with all my strength, but screen will not come loose from the frame.
Has anyone removed the screen on their phone, or does anyone have experience in doing such things, to help me pull this off?
I believe that if I manage to remove the screen, and clean the layers, screen should be back to 100%.
I asked a friend of mine to lend me his heat gun, but I am afraid of applying too much heat and killing the LCD, or doing bad things to the plastic body of the phone.
Any help is greatly appreciated.
Have you checked out the dismantle video on youtube? I believe you have to go through the back.
https://www.ifixit.com/Teardown/Nexus+5X+Teardown/51318
NO! I know how ti disassemble the phone... What you are posting doesn't even include the screen separation from the frame.
I have been watching videos a lot, but I myself, after following them, am unable to separate screen from frame. And to be fair there is just 1-2 videos out there that actually show people doing that. In one a dude used heat, a suction tool and a precision knife to lift the screen from the frame. I don't think using a metal tool on a heated plastic, to lift a glass is a good idea, especially when the adhesive is so strong. I guess the screen from that video has already been removed, that is why it looked so doable. I bet if I try that, I will f*ck up my pristine frame (phone is 1,5 months old)
You have to go through the back. See link https://youtu.be/Y8XpqwLsrUo
Same problem here, I cannot manage to separate the screen from the frame. Did you manage to remove it?
I broke that damn glass into pieces from the back holes, allowing me to insert a guitar plectrum and finally remove it all. Fixed

Just found the way to make sure that UV glass protector (e.g. dome glass) works with

I saw many complaints about domeglass or other uv glass brands doesn't work with fingerprint reader on S10. I just installed uv glass protector(mine is not domeglass) for the third time and now I can use fingerprint scanning without any problem. My first two times were total failures. I could not even re-register my fingerprins after i deleted them.
The method is also verified by my friend that use different UV glass brand.
Short instruction:
Make the glue layer at the scanner part as thin as possible.
Long instruction:
Before installing the glass, use an adhesive tape to close all ports at the bottom. Then follow the instruction given by the product you bought. However when it comes to the part that you have to use UV lamp. Do the top part of you phone first then use a plastic card to squeeze from the middle part of your phone straight to the bottom in order to make the glue layer as thin as possible or you can just use you finger to press on the fingerprint area so that the part will get thinner. Clean all the glue that comes out when you press (that's why I tell you to close all the ports at the bottom first).
After you do all above steps, wait for one hour for the glue to be totally settled, delete all previous fingerprint registration. It will be a bit harder to register new ones but when scanning, it will be very similar to what you did with bare screen, only a "very little bit harder"
Those are pretty much the (new) instructions for Whitestone, press and UV extra at the FP.

Question [PSA] UV Tempered Glass that works with FP w/o the dot glue

The tile says it all.
This: https://www.amazon.com/gp/aw/d/B09KC72DWF
Work with the FP scanner, without the dot glue and is tempered glass.
I f***up and even though I used the tape, got glue in my speakers. It was a pain in the @$$ to take out and I had to use a sewing needle once it cured. So be careful!
Otherwise, the install was easy.
Also, "Currently unavailable" unfortunately. But thank you.

What do you mean by "dot glue"?

Some glass protectors have a spot where the fingerprint reader is located to improve responsiveness, so the rest of the protector is "floating" over the screen, but at that position, it sticks. It may work, but it's ugly as f*** and completely breaks the apparel of the phone. I guess for what he describes this one comes with the LOCA bottle you have to pour over the screen and then cure with the UV light.

Oh I've seen those but they where mostly made to deal with the issue of ultrasonic fp sensors. Didn't know they made them for optical sensors, I guess trying to help with the P6 sub par sensor. And yeah they look ugly af

For what it's worth, my P6P in-screen optical fingerprint reader works perfectly for me, and my Samsung Galaxy Note 10+'s in-screen ultrasonic fingerprint reader was pretty terrible.
Honestly, I've not had any issue with the FP reader, coming from a OnePlus 7 Pro I feel it even quicker than there, so I don't quite get all the hassle.
BTW, reading the good comments from the Mocolo glass protectors I just ordered one, let´s see when I apply it if the FP reader keeps working as intended.

This is correct.
My FP scanner works amazing well. Way better than the OP 7 Pro on my parent's phone.
This screen protector was worth the hassle it took to install.

I tried the UV glue glass. And glue went in to my speaker too, then the volume of my upper speaker become very low. When I make phone calls I cannot hear anything. I tried all the method but cannot sovle it. So I have no way but to disamble the screen and clean inside. Now it's better but I can tell it's not like before. I guess there are still some UV glue block the outlet of upper speaker. I figure out if you want to disamble the upper speaker and clean the outlet you need to remove the battery and main board first, which is not easy so I gave up.
Btw I did tape the speaker but UV glue went in. And I also find out once glue flow in to gap between screen and frame , after you UV light it , it get hard and swollen which will make the gap larger.
Although tempered glass feels really good and has no impact on FP sensor, I just went back to film screen protector after this terrible experience

Youve got to be very,very careful with the UV glue and use a good strong tape to cover all the openings. I runied my Oneplus 8 Pro because of the glue but my P6P install was good.
Yes. The tempered glass protector I have only leave me with around 1 mm between the glass edge and the upper speaker slot. So it's impossible for me the apply a tape cover the speaker effectively.

I used a sewing needle to get under the glue and pull it out. Don't worry, the speaker gills are kinda deep. That said, be careful and don't just ignore that's the speaker is there lol.
