Plastic interfering or scrolling issues? - Huawei P20 Pro Questions & Answers

The p20 pro is delivered with a screen protector. On top of this is also an extra layer of plastic with a red tab at the top, meant to be removed before using the phone. I have to leave this second plastic layer on the phone to be allowed to return it.
Scrolling isn't good on the device. It's like the phone hold off scrolling until I've moved my finger some distance in a direction. This causes scrolling to be unsmooth and I'm not sure if it is due to the extra plastic layer interfering with touch sensitivity or if I have a faulty device or even worse: this is the way it is.
See video below for illustration. Notice how scrolling won't move right away with the finger. How are your phones with this? I hope that it's just the plastic but I'd rather not risking it to rip it off and find the issue remaining and no return.
Comparing on my current phone, a note 8, scrolling follows the finger right away.

It's not the plastic protector that's causing it. I have removed it and mine is exactly the same.

Sad to hear it. It makes the scrolling experience feel like something from the entry level. I really wanted to like this phone but it seems the camera is all that's going for it in my book.

Seems to be a Huawei thing. I've had the same on a Honor 9 but it was much worse as it made it impossible to use it like I use my phones normally. It doesn't bother me too much on this one even though I notice it. On the Honor 9 it was hardware fault or just a bad digitizer because I had another Honor 9 too which was just fine and instant in the scrolling. It might be the digitizer this time around too. If I enable "show touches" under developer options it just doesn't trace the finger when doing smaller movements.

Same thigh here. It behaves the same way when showing touches so something tells me this may not be software but it's hard to tell. Seems some do not have the problem but I kind of get the feeling that non power users may not even notice it. I'm just the kind of person taking note of things like that this and it ruins the entire experience.
Add the horrible oversized ui to this and a few of the other kinks and suddenly all this phone seem to offer is a great camera and a lovely placed fingerprint sensor.

This seems to be the same issue as we are having in this thread.
Here is a video of the issue that I made. Note this is without the plastic interface OP was mentioning.

Checkered prints on screen

Hey guys, I got my Nexus One earlier this week, and I love it so far, but I have some issues with my screen.
There seems to be a checkerboard kind of print on it. I can't really explain it any better than that. At first I thought it was maybe residue from the plastic wrapping it came in, but after a week and some thorough cleaning, it's still there.
It appears to be finger grease, which indicates that there's a problem with the glass. After cleaning it with a microfiber cloth, the pattern is gone (or at least extremely hard to see), but after some use, it becomes clearly visible again. To me, this says there's extremely small deviations in the glass, which finger grease gets stuck in where it isn't removed by a quick wipe down. To further support this theory, the screen seems more rough swiping top to bottom, than bottom to top, which would make sense given the pattern.
Edit: After thoroughly cleaning the screen, the breathing on it (like a window), my breath makes the pattern clearly visible. Though, this doesn't really confirm anything.
Has anyone else had or seen this issue? Any recommendations on fixing it, or should I be calling up HTC?
I'll try to take a picture when I get home from work, but I doubt it'll be visible. My only other camera is an iPhone.
I think what you see is the digitizer. It is barely visible but you can see it on every touchscreen phone

Not to be one of those guys, but I never saw the digitizer on my iPhones, until I got my Nexus One. Had a moment of uh, my phone's screen is really going to be like that? until I realized what it was, and now I only notice it at an angle in bright light.
You are right, with you can see it I meant just in theory.
I saw it the first time on an n1 too, but only once or twice, but never saw it again since it is so barely visible

Yeah, I definitely knew what you meant. Just wanted to throw that out there.
It kind of sounds like your phone is suffering some form of Newton rings. In the phone world its when the front screen presses on the digitizer and creates light refraction, thus looking like oil swirls. My HTC fuze suffered this horribly and it gets worse over time as far as touch sensitivity goes. I would recommend calling HTC. My nexus doesn't have this issue at all.
I am wondering now if the shipping nexus ones have the LCD screens instead of amoled because of the shortage in amoled screens though.

I don't believe I'm seeing the digitizer. This is on the glass, not the display itself. It's visible on the bezel around the screen as well. I'll try to take a picture when I get home from work.
Edit: to be clear, it covers the entire front glass, over the display and the bezel, and is clearly visible even with the display on.
Strange issue. Never saw this when I purchased mine, though that's probably because I was excited to turn it on rather than inspect the body.
I think it probably has to with the adhesive material between the digitizer and the display not completely curing. When it does cure you don't see it very well but when you use the phone and it heats up the pattern comes back. At least that's my theory.
Sent from my Nexus One
Took some pictures. For the sake of size, I'll link them.
Full screen, off
Screen edge, off
Screen edge, on
These are pretty accurate, in terms of what daily usage is like. The full screen one might be a bit much, I had to hand print it up to get it to show in the picture, but the one with with the display on is pretty much what using it (indoors) is like.
I've seen that sometimes on my phone, but it's not nearly as often as it seems to be with yours. Not sure what that is then.
I had a problem with my screen that can only be described as similar. One of the replacement Nexus Ones I received had an incomplete oleophobic coating where the entire bottom 1/4th of the screen would be very clear and the top would get cloudy after light use. There were also a few circles just like the bottom of the phone on the upper portion as well.
I called HTC and they just replaced it for me. Sounds like you should do the same.
Whoa, those look like the glass was machined improperly or that the adhesive issue I hypothesized about earlier could be the culprit.

Same here, they're extremely nice.
I wanted to get a replacement battery since mine has short battery life and constantly overheats, so they forwarded me to HTC but unfortunately for some reason they didn't have my IMEI or S/N on their records, so I couldn't do anything.

[q]s-pen= awful

Does anybody else find the S.pen of the SGN really bad??.. when it comes to drawing some stuff..? Any remedy for that?
Sent from my GT-N7000 using XDA App
i don't draw but i do annotate quite a lot, and it feels like the calibration is a bit off. what in particular about it is your concern?
Like, the place where i point the pen and the place where it writes is not the same,the location where it writes is a little bit to the upper left( not precise)... and its also has a latency after writing...
Its not a very big problem for me just a little critic...

I've used five s-pens so far, and two of them were significantly worse than the other three. Good news is that the problem is most likely with the pen itself and not with the Note!
Try getting a different pen (e.g. there is an official Samsung holder that comes with another pen). For the offset problem, try to switch from right to left to right... several times --- sometimes that helps to make the offset more reasonable. Also experiment with the angle of the Note as you write, often that makes a difference too.
Just my two cents...
The reason why it seems a bit of is done on purpose.
You notice this when you change your writing hand in the settings.
When it's set to your right hand, the drawing is slightly left of your pen. With the left hand it's the other way around.
This is done so you can see what you are drawing/writing and your hand is not in the way.
I know it sucks, but Samsung made it this way.

This is true, but some pens have larger offset than the others. I think some of them have sensitive elements inside aligned better. And actually this works rather nicely if the offset is reasonable, at least for me. Takes a bit of practice, but feels quite natural after a while... if you think about it, some offset is appropriate, since there are three surfaces at different depths: the writing surface, the "displaying" surface, and the actual surface which is sensitive to the pen's movements (this one is quite deep, it's behind the screen, not in front of it)...
Try different pens before giving up
Yeah the calibration is not exact to the point. When I'm writing words normally I'm not really affected, only when it comes to drawing in slow motions, the placement is off and it's frustrating for drawing little details.
However, I managed to dig out an old stylus which came with my ancient fujitsu tablet PC and it's calibrated perfectly.
I've noticed that the angle to which I hold the s-pen to the surface makes a difference in percieved accuracy.

With the Fujitsu pen, does it have calibration issues or extra lines if you write on it upside down, like if you were lying on your back? My biggest pet peeve with this phone is that I can only use the pen if I'm sitting upright and holding the pen just so, otherwise calibration is way off and a lot of unintended lines appear.

I've noticed this too. It's most apparent to me when I set my phone on a table, holding the pen by it's very end. Touching the screen with the point and changing the angle of the pen relative to the screen--without moving the tip of the pen;s position at all--you can see the cursor move with the angle of the pen, even though the tip stays in one place.
The best way to fix this, in my mind, is for Wacom to do on this phone what they do for a lot of their tablets--have a little dot show up on the screen when you hover your pen, so you know where you'll be drawing.

This is a damn good idea right here. Someone should forward this to Samsung before they roll out the ICS update.

Well you guys said it all... drawing details,drawing slowly, lots of unwanted lines appear...etc...
I see, so its most likely caused by the pen rather than the note itself... ill give the app(touchscreentune) a try..thanks.

Quality feel (use of materials)

Rate this thread to express how you think the HTC 10 feels in terms of quality. A higher rating indicates that it feels premium and high-quality (attention to detail is high, manufacturing defects don't exist, etc).
Then, drop a comment if you have anything to add!
My home-button/fingerprint sensor seems to be loose, after a while of not touching it the first touch seems to depress it back into place and then its fine for a while.

Same here. I thought it's just me. Feels annoyed at first. I can't stand if something wrong happened with my phone (especially hardware issue). Usually I'm thinking to sell it and buy a new one.
But for this issue, I think i already get used to it.
*cheers*
Same on the loose home button
But i guess its not that bad as i forgot about it for the last 2 weeks...
Screen defect is horrible, design wise could've been 2mm thinner.
What screen defect are you referring to and is this a widespread issue?
My vibrator motor became loose one night, i only had it for 20 days tops and never dropped it

Hello,
I have the same issue. My Home/fingerprint button is loose from the center to the left.
When I push it, I sometimes here crunchy noises (rarely when I put my thumb on it which is enough to unlock the phone).
The home button and the fingerprint sensor are both working fine so I won't send it back for now but this is an annoying detail (I can't stop thinking about this when I look at my phone ).

I generally love this phone. The feel of the case is great and the glass screen is equally smooth. My only complains are:
1. Camera bump. I hate using a case, but I feel like I'm going to scratch / break my camera off because of how it sticks out of the back of the phone.
2. The sharp edges on the bottom, specifically around the USB port cut into my finger when I hold the phone.
3. While I think it looks fine on the Carbon Grey, the plastic strip along the top looks bad on the Silver version of the phone.
I don't think I would've ever noticed the looseness of the home button had I not read this thread. I never push on it, just lay my finger over it to unlock or go back home so it never occurred to me to check for movement. My screen is great (may have slightly color issues, but I don't really compare it to other devices so it doesn't bother me). The body of the phone to me also seems to be top notch. No chipping or scratches as of yet...my Nexus 6P chipped and bent rather easily and I tend to take care of my phones.
This guy destroys phones and he said the HTC 10 is a Tank.

Perfect so far but I am disappointed with the black coating... a small drop and the bright aluminium shines through immediately... Why dont they mix paint with metal and then shape it instead of coloring if after ... its annoying watching those dents that are super visible just because it is painted :/
because you can just mix paint in with molten aluminum...
I have my 10 since yesterday and I am very happy with the build quality so far. The device has a premium feel to it and it is definitely the best quality smartphone I have ever had (including the iPhone)

Hello, I'm new here, I live in Germany, HTC is not so popular here , so I checked the international forums for information about my HTC 10.
I got my HTC 10 in August and I have the same problem with the home-button/fingerprint sensor. I'm anytime very careful with all my mobiles, so I have no idea why it is happen the same.
May I ask you it is getting worst with the home-button/fingerprint sensor since your last post here?
Sorry for my poor Englsih )
It feels and looks like an Iphone 3GS to me
this feel that every flagship phone should have
I have the newly released red one and the power button is a little hard to press, I kinda have to press it with my nail to push it.

How bad is the screen gap, or how does it affect you?

Hello everyone!
I'm looking forward to upgrade my phone and most chances it will be the Pixel 5, notably for its small size compared to my current phone (OnePlus 3T) and 5G connectivity (As you may have realized, I'm not upgrading very often and I want to be future proof on connectivity, otherwise I would've take the 4a)
Anyway, I've been following and reading about the phone since launch, and I know there was a screen gap issue.
My question is, is there anyone here who have this gap, and if you do did it affect anything about the phone in that time? does it get worse? stays the same? or any other issues I should be aware of?
Thanks in advance!
The gap is minor. Overblown issue imo. You can barely notice it. I can slide a piece of paper between the body and screen, that's about it.

Thanks! that's the kind of response I hoped to receive, I was somewhat worried when it was first discovered and hearing about people returning their phones. How long do you have the device if I may ask?
And anyone else who can share their experience, please, go ahead!
Shoved mine in a case and forgot about it.
I don't even think mine has a gap at all. Haven't tried sliding a piece of paper in between but I don't think it will, looks perfectly attached together to me
Mine looks fine as well, I submerged my phone for 20 minutes in the sink just to test everything and it's fine. Did get the warning about wet usb port but that's obvious and expected. I just get on with it, I couldn't detect a gap, tested the best way I knew.
Wow, thanks everyone!
One more thing, as far as I know this phone isn't officially sold where I live but rather is being imported independently by certain stores. Is there any detail I should look for in regards to compatibility with frequencies? especially 5G? (Again, 5G is the main reason I chose this phone over the 4a).
Really didn't notice it....

Question Bad sensitivity spot issue

Hello,
I need some help from the xda community.
Just recently bought S21 Ultra, but I have an issue while using S pen with any application that has push sensitivity recognition just in one spot.
For example 'Infinite painter' or 'art flow' with sensitivity brush like 6B pencil.
I'm not completely sure that it is hardware (display) issue of this phone or all S21 Ultra have this issue.
I want to ask someone to try it either to confirm or deny. If it is the issue of this particular phone, I still have some time to change the device.
Thanks for your help!

yeah, I've googled this issue, I know about magnets. But it looks like there is something underneath the screen that produces some magnetic interference. And it works with very big pressure... I was just wondering if everybody has this issue and just don't care\know, or it is just me. That's why I've asked somebody to test it.

So, as I understand - you did try S-pen with any application that support sensitivity recognition in this area and it works? The general notepad or any other application that is just for writing works in this area of the screen. The problem is only with push-level recognition.
How do I enable the pressure sensitivity?
Here is what I achieved on my S21 Ultra (snapdragon, USA t-mobile variant) using an older s-pen taken from an older note. But when I used different pressure, the Infinite Painter app acted like the pen was either on or off, but no gradients in between. Like I dragged the pen across the screen and pushed harder and softer, but the result was just no ink when too soft, and pure black when hard enough or harder. Nothing in between. Is this because my s-pen is too old, or did I need to turn on a setting in the phone or the app? I selected the 6B pencil in the app.

I don't have infinite painter or any other painting app, but I tried my S pen on Samsung notes and there doesn't seem to be any irregular spots on the screen. Both tracing and pressure work on all parts of the screen as far as I can tell. I used my Tab S7's included S-Pen.

Thank you! Now I'm wondering if it is S-pen issue. Just noticed that if I hold the pen almost completely 90 degree to the screen, it just works fine on this spot.
