Nexus 4 - Touch Screen Sensitivity Test - Nexus 4 General

I'm trying to find out how sensitive the screen is to touch on the Nexus 4.
Could those of us fortunate enough to have received our Nexus 4's run a short test and post the results? The reading required is for tapping the screen - not swiping.
You need to enable developer options first which was hidden in the latest update to 4.2:
Go to About Phone and click on build number 7 times
Click to expand...
Click to collapse
Then enable the pressure measurement:
You can view the pressure by going to Settings -> Developer Options -> turn on Pointer Location. This will allow you to see the Prs of each tap in your status bar.
Click to expand...
Click to collapse
So,TAP the screen as lightly as possible (DONT SWIPE) and post the Prs number displayed in the status bar here. Cheers!

I got a PRS of 0.48.

So what would be a good value?

The lower the value the more responsive the screen is to taping. For example when typing on the keyboard, it help to have a low PRS of around 0.2-0.3 so you don't miss any letters.
Nexus 7 PRS is as low as 0.01.

Lowest value I got after a quick few tries was 0.26.
Sent from my Nexus 4 using xda app-developers app

Yup I also got 0.48. Keyboards good though I dont miss anything.
That was average, The overall lowest I got was like 0.35.

Lowest . 21. 36 average
Sent from my Nexus 4 using xda premium

0.26 was the lowest i got. this is with the thick ass initial screen cover still on. seems plenty sensitive to me.

This is pretty interesting. What sort of PRS does the iPhone 5 get?
And what's PRS?

A comparison is definitely interesting.
But sounds to me like the numbers can also say something different than it is in real life usage.

Mainly getting 0.50 - 0.55, got a few 0.3 something and one 0.28

I get .15 on the Nexus S. It has a Zagg Invisible Shield (if that makes any difference).

Lol whaat? I get 0.02 on my Galaxy S2

0.14 - galaxy S
Just for comparison

galaxy nexus also is at 0.27+ but no big deal, no one complained about it. Nexus 7 does indeed has great sensitivity, at 0.01-2 easily.

Wow these values for nexus 4 aren't all that impressive I can easily get .15 multiple times on my g2
Sent from my HTC Vision using xda app-developers app

My Galaxy nexus on 4.2 averages PRS 0.38 while typing with light touches the lowest value I can get by really trying is PRS 0.26 so don't know if its a 4.2 trait
Sent from my Galaxy Nexus

0.3 to 0.6 on Xperia mini pro.
Lol
Sent from my SK17i using xda app-developers app

wow. i get 0.01 on my toshiba thrive and it wont change.... am i doing something wrong? lol

I really doubt these numbers are strictly comparable between phone models since its probably just reported by the touchscreen driver and they may all have different scales

Nexus 4 screen dots

Hi, I have noticed that when I have blocked my Nexus and I put it reflecting the sun light, I can see a grid of points, I don't know how to explain, but I have recorded my smartphone to show you what I'm talking about.

Thats normal its your touchpanel sensors i believe ive seen it on every touch phone i have had.
Sent from my Nexus 7 using xda app-developers app
Didn't see it on my 2 Samsung Super AMOLED screens but it was also visible on my old Xperia X10. Probably depends on the screen technology.
Sent from my Nexus 4 using Tapatalk 2
I've also noticed that. It's not bothering though as it can be seen only when the screen is off. I know that Galaxy Nexus didn't had it. But I think it's kinda nice looking.
Sent from my Nexus 4 using xda premium
As it has already been said, it's the touch panel. Whether you can see it or not depends on the used touch panel. On some phones you can see it, on some you can't.
It's nothing to worry about.
Same here!

This phone destroys the Nexus 7

I got a nexus 7 for Christmas and don't even use it because of my nexus 4. I mean sure it has a bigger screen but it's slower and with the latest Paranoid Android update the screen on my nexus 4 is better as well!
I have a top of the line laptop and top of the line smartphone. Where does a dated tablet belong in this scenario? Maybe I could use it to watch Dragon Ball Z at the gym. Or load it up with porn and use it as a mobile fap station.
I think I'm just going to sell it, what do you guys think I could get for it? It's a mint 32gb wifi model.
Thanks a ton XDA!

You can't compare a phone with a tablet, but still I understand what you mean. The Nexus 7 is a value for money tablet with feature pack functionalities, but the screen is not up to par.

Why not use it for porn? Sounds fine to me. 7 inches is a usable size for anything sex-related (badum-tish)
the nexus 7 is much better for gaming(especially tegra optimized games) then the nexus 4.

dont think theres anything right now the adreno 320 can't handle. i mean come on, the unreal engine demo (epic citadel) ran on 60 fps on the N4. so it doesn't really make any difference. and the screen on the nexus 4 is significantly better than on the nexus 7.

My mate ran the spiderman man game on his nexus 7 and it lagged slightly, yet on my nexus 4 smooth as butter, yet it lags with vice city maxed out, not hard lag but in high intensity areas
But a lot of games are optimized for tegra and have added effects and graphics. I don't think he meant that it can't handle it, the nexus 4 is way more powerful. But games look better on the nexus 7.

Maybe wait for 4.2.2, because 4.2 runs like crap on Nexus 7.
I've noticed too that I'm not using my N7 much since I got the N4. For me though, it's more of a convenience thing. I kept close tabs on where the tablet was before I got the N4, but now I'm not caring as much where my wife leaves it.

Good decision. If not using it, sell it.
However, I use n7 more than n4 at home. I love my n7.

I absolutely despised the N7. Hated the screen, headphone out sound quality, and the build quality. I bought an iPad for my tablet needs. Most of the time you get what you pay for with the Nexus 4 being an exception. It's a sweet piece of hardware that's definitely under priced.

The Adreno 320 is way faster than Tegra 3, that's not the point. Gaming is still better on a tablet than a phone. Unless you have to tilt the device a lot .

could someone type this in the terminal on the n4 -> su (press enter) -> dmesg | grep lcd
but you must reboot before doing this.
it should put out a line where it says lcd_id: primary or so. could someone post whats stays there like primary?
All Nexus 4's will be pure Google phones. No aftermarket bloatware will be found in a N4 from Google or N4 from T-Mobile. :good:

Looks like you missed out typing 'su <enter>' before typing the dmesg command.

A sudden fix is not likely but not impossible. Would one of you please go to
Settings/About Phone, scroll to the bottom and take a screenshot (power button and vol-)?
I'm interested in the Kernel Version and Build Date.
I wonder if they are different than the ones of the latest 4.2.2 release.
The highlight of my day was when my life long Apple user borrowed my phone to check a sports score and said man this this feels so sexy and is fast as hell. The screen is nice. In using trinity and custom gamma.

Hi
After going back to stock 4.2.2 using the factory images and clearing everything before installing the images I noticed the LCD colours have changed completely. The more washed out look I was used to is replaced by a much richer display, matching the HTC One X now, although not quite as overly saturated as the One X which is a bit too saturated.
My phone is from November and I was very familiar with the more washed out look, and I just assumed it was fixed in 4.2.2 that I see now.
Perhaps the new settings can only be picked by a complete wipe and install, hence phones shipping with 4.2.2 look better as they are a clean install, whereas maybe an OTA isn't changing the calibration settings.
Regards
Phil
Kind off topic , but im thinking about ourchasing from the play store and continuing using tmobile. Will the insurance and warranty work the same as if in had purchased from them directly? I jist dont want to overspend If I dont have to.

PHYSICAL Home button HW Quality

Just picked up the N3 yesterday - Nice device - But one thing that I notice - Is the Physical Home button doesn't seem as solid as the one on the N2 - It seems to always droop a little (very little) to one side (too much play in the housing?) - Anyone else notice this - or is it just my device?

Well I guess that if it annoys enough people - maybe Samsung will manufacturer a collar to slip around it - to add more stability?

What color is yours? I have the jet black and everything is solid. it even takes a fair amount of force to get the S-Pen in and out. Ive noticed with past Samsung phones white ones tend to have more build quality issues for some reason.

Mine is black - Spen is fine - just the home button - if you gently run the back of your nail against it from side to side - you can see it moves...
It's not like it's falling off or anything - just more movement than the home button on the N2.

Hi,
I made a X-Ray image from my Google Nexus 5 @ 75kV. 8mA, three different contrast settings.
NFC, Qi charge coil, accu, cameras, speaker... readily identifiable.
Furthermore the high absorbtion of the ceramic power button and volume rocker.
Have fun!

Hmm, I'm thinking something different... I was looking for something suitable to use as a drive icon, for when the phone is plugged in to the computer. I think this might be it!
This is really cool - and yeah, some high-res images for wallpapers would be grand.
Even better, use it as a background for the N5 cropped to the right resolutions.
OK, CT scan next
I will check tomorrow if I it is possible to take a picture in higher resolution.

Hi Guys,
here an other one, combinated two pictures with a bit more sharpness.
A higher resolution is not possible with the hardware I get here, sorry for that! I think i could record a new image playing around with the camera frequency (=focus level) but i dont want to x-ray my phone 20 times to get an image which is a little bit less blurred.
