Why Yoga tablet 2 screen looks so blurred and sharpened at the same time
Have you been wondering why your screen on the 10" Yoga tablet 2 with KitKat doesn't look really crisp even with some obvious sharpening applied? Here is why!
Lenovo screwed up twice!
1. Blur filter is applied. (KitKat ONLY) The BIOS/bootloader defines wrong display resolution. The Intel graphics driver (i915) gets confused and switches on panel fitting which includes a blur filter (fuzzy filter). Normally this is used if the display resolution is different from the frame buffer resolution to scale the image. Here the device just scales 1:1 and applies the filter. Luckily the driver is open source and it turns out there is a way to overwrite this feature No longer true for Lollipop. Thanks Lenovo
2. Sharpen filter is applied. (KitKat and Lollipop) The panel is not programmed correctly. When disabling the CABC feature (/sys/lcd_panel/cabc_onoff) the sharpening effect is gone. But CABC should have nothing to do with sharpen. Unfortunately the specs of the display (AUO B101UAN01.E) are not public so I cannot verify if the correct MIPI DSI commands are sent to the panel.
So our display is softened then sharpened again! What a waste!
Both workarounds are only temporary. After each screen off/screen on sequence the old values are restored by the system. So we need an app which sets the values after the screen is switched on. Or a new kernel. Or Lenovo cares to fix it in a future release
Fix (Root partially required)
I wrote an app which can disable CABC / sharpness filter (requires ROOT) and can disable the blur filter (KitKat, no root required) . Of course I am not held responsible if you brick or burn your tablet. I tested this on my 1050F with rooted firmware S000143_150105.
1. Copy app to device and install
2. Start app and select your setting
3. The settings may apply only after switching screen off and on again.

Bugs / issues
- may not work directly after reboot, only after screen on/off
- fullscreen video may switch on CABC/sharpness filter again
Any suggestions? I'd be really happy if you could test and report
Cheers!

Update Jan 21
make more reliable and add complete source
Update Jan 26
Reliable implementation as app which automates this process.
Update Jan 30
new version 1.1 (please uninstall old version!):
- add option to start at boot and enable/disable applying the settings at screen on for manual operation
- add little delay after screen on for more reliable operation
- app should be harder to kill by the system
Update Feb 2
new version 1.1.1:
- Fix occasional reboot issue when using the setting on display on. Turns out Android sends screen on broadcasts sometimes even if the display is off. This causes a crash if the filter settings are applied.
Update Feb 11
new version 1.1.2 (please uninstall old version):
- hopefully ultimately fix reboot issues by using different method to start on boot
Update Apr 30
tested with new firmware S000198_150422. Same as before. Lenovo has not fixed the issue, but the app works like before
Update June 3
New version 1.1.3:
- fix full screen video playback re-enabling CABC/sharpness filter. As for CABC itself root is required.
Update June 17
Update for Lollipop version 1.2.0:
- blur filter disable no longer needed
- sharpness filter is still present. If root becomes available for Lollipop this should work there too
Update June 19
Fix for rooted Lollipop - version 1.2.1:
- the mechanism for sharpness filter disable from 1.2.0 didn't work, probably due to SE Linux restrictions
Matshias, you are a legend!
I bought a Yoga 2 10" a couple of weeks ago and the odd blurred and sharpened effect ruins what is otherwise a great little tablet. I'd always suspected it was some kind of odd scaling issue, but I haven't had time or sufficient Android knowledge (or root access on my device) to properly investigate it, beyond making up some test images with alternate 1 pixel wide black/white lines - which were rendering as grey on the Yoga 2.
I had a support ticket raised with Lenovo about the issue, so I've referred them to this post and one on the Lenovo Community forums.
Thanks for your hard work, hopefully Lenovo will implement the fix in a software update soon!
Cheers,
Richard
Thank you!
matshias: Thank you.
The blur filter disable makes a HUGE difference. I really appreciate you taking the time to post your results, hopefully Lenovo will take note and implement a permanent fix.

Hi!
I have just started using your app with the latest firmware on a 1050L.
0) Unrooted device
1) installed your app and applied the non-root part of the fix - worked after screen on/off
2) rooted device with temporary cwm solution from this parent thread (- which worked as well)
3) applied the root-required part of the fix from your app - works as well
Thank you for this!
Great great great! Like the others here I was looking for a solution to this Problem since I bought the tablet.
I am really satisfied with your APP, now everything is way sharper.
BUT: When I test the screens resolution with a screen test APP, only the horizontal ( long sides) resolution seems to be right now. The vertical resolution (short sides) is still just grey, when testing single pixel lines.
Do you have the same Problem, what could cause this?

I see the same if the sharpness filter/CABC is still switched on. If you have root then try disabling the sharpness filter as well and then the screen test look fine. Obviously the sharpness filter in the panel is not uniform in all directions and seems to prefer horizontal resolution (in landscape mode).
Thanks again for the advice!
I just had to enable root, really cant look at that horrid screen anymore! But now it really looks as sharp as an 240ppi Display should look like!

After installing the app I have problems.
In 10 minutes my tablet rebooted 3 times . Android not asked to reboot.
It was crash of sistem. My system is rooted.
After uninstalling I had no problems.

Did you use the start on boot feature? This might cause it. I uploaded new version 1.1.2 which should fix that problem. Let me know if it works for you.
this is a fantastic fix, one that Lenovo should have implemented themselves
actually when i just got the tablet over christmas, it was running older firmware in which the blur filter was actually not enabled. yes i now realize the text was "over sharp" but it was clear, and what i expected for the price (i.e. not double the price for a galaxy tab S) but i was fine with the sharpness, it looked good, and the tablet otherwise suits my needs perfectly, and gotta love that built in stand. i didn't even know what people meant about the image quality, considering the mid-range target audience of the tablet.
anyway, i recently got the OTA firmware update to the current S000143_150105 and that's when it messed everything up. it enabled the blur filter, and it looked HORRIBLE. i tried to accept it because at 1 ft from the tablet, the text actually looked all right, perhaps even a slight improvement because it was slightly softer. but the blur filter is applied to EVERYTHING, so all the images and everything on the screen was blurred....it was like looking at an HD monitor with a state of the art GeForce video card but using the standard windows video drivers...everything stretched and totally blurry.
this is a great fix, i don't have my tablet rooted and don't want to take the potential battery hit to disable the sharpening filter (since i think it looks good just with the blur filter disabled). it might be in my head though, but i feel like the system is a little more sluggish...maybe due to the update, maybe because of this (great) app...i wish lenovo would fix this, seems easy enough. sours me to an otherwise great tablet for the price.
speaking of battery, i noticed in the last day after installing the fix that my tablet powered off sometime during the day, and when i restarted, the battery had drained about 30%. and it continued to drain faster than before. i previously got well over 10 hours of usage time playing movies and web browsing, in addition to up to several days of standby....today i had to charge it within 24 hours and only got about 7 hours use time and 13 hours standby...any chance it's related to the fix, or has anyone experienced it after the firmware update?
@digitalatlas: Thanks for testing the app.
Regarding your observations, I don't think sluggishness can be attributed to the app. After all it doesn't do much. Only when the screen is switched on or you manually start the app it changes the kernel setting. So it really shouldn't have any impact on performance.
The battery life should also not be affected by the app itself. It does not have any background tasks other than the kernel setting mentioned above and it shouldn't wake up the device as well. Although I saw occasionally that my app gets informed that the screen was switched on even though the screen was not switched on. That caused some reboot issues. But that was fixed with version 1.1.1 and 1.1.2 and I didn't see a reboot since I use 1.1.2. Also there are reports of hangs/reboots by other users unrelated to my app. Anyways it might be the case that changing the kernel setting has some other effect on the hardware, kernel and battery life. According to Intel documentation the filter is not meant to be switched on or off while the display is active. However, it is the only time it is possible to change it in our system. So to be sure we have to test and disable/uninstall the app and see if the battery life improves.
Hopefully Lenovo fixes this with an upcoming update!
Thanks!
Just got this tablet in the mail today and was disappointed by its display. So grateful for your fix, its like night and day with the blur gone. Guess I have a good reason to root now to get rid of the sharpness too. Mind me asking what method you used to root for this firmware?

It is easy enough and works fine, but keep in mind that there might be issues with OTAs.
I'll keep track of the battery over the next little while, hopefully it was just an aberration that first charge. I'm getting better results with this second charge since the update and your fix.
Could you or someone post a picture shoeing the effect of turning the sharpening filter off? Might help some of us decide it rooting is in fact worthwhile. Thanks!

I tried taking pictures but it doesn't really show the effect. Instead I made two screenshots and recreated the filter with GIMP. It should be very close to what the panel does.
Does anybody have any info from Lenovo? I think that this is preposterous! How can someone do that and have it go through testing? Unless there were no tests at all.
Buying Lenovo was a mistake.
v1.2 tested on my new 1050F. Awesome. I was disapointed by the screen but now it's perfect. Thank you so much to have done this patch!

AMAZING PICTURE QUALITY!!.
Without blur picture is good, but witchout blur and sharpness image quality is FU…NG AWSOME!!

Great app, thank you
Are you all running this with rooted devices? Mine is not yet rooted but notice a big difference with this app. How much better is it if I was to root the device? Thank you so much for this fix. I recieved my tablet today and was very disappointed with the display.
1) Volume controls, seriously google? what are you smoking? Why is it way more difficult to change my ringer volume then it needs to be? why do I need to change media volume if I'm not actually listening to media?
2) Much more professional UI, if I wanted an iPhone I would buy and iPhone, Google might as well called this update "Apple Pie"
3)Much better notification/quick toggles pull down with sub-menus for bluetooth and wifi. Why did Google remove this?
4) Split screen mode is usable again! (Videos play in split screen too!)
5) No need to worry about an OTA rolling and screwing things up, I like the piece of mind that my phone will stay on the final Oreo update until I feel Pie is stable enough (9.1?)
6) Multitasking is faster (although this can be solved with an adb command, the whole concept is still a downgrade.
7) Pie is not used by many people at all, in fact the number of total android devices running Pie is less then 0.1% of android devices Source: https://developer.android.com/about/dashboards/ - We are essentially beta testers even after the developer previews.... Oreo however is up to nearly 20% distribution.
8) Battery life using Franco's Naptime app for aggressive doze gives me insane battery life, Adaptive battery is pretty useless when you use such a powerful app like this one.
9) Adaptive brightness is awful on Pie
10) My clock is where it has been for the past 7 years on Android phones, this notch thing just needs to die. Google needs to add a boolean value in systemUI for the left clock and assign it a true value for phones with a notch, and false with a phone with no notch. Seriously, do this!!!
Now before you guys come in here bringing up security bulletin updates, it's a fair point but I would just like to say that no security update will save you from being a noob, don't download shady apps, don't connect to unsecured public wifi networks, don't browse shady websites and don't click on everything you see. Much like a PC, you can get the latest Windows updates and anti-virus definitions but if your foolish and browse around unsafe and shady websites and installing shady .exe's your going to get yourself in to trouble and no security update will save you. The best security for Android is your brain.
I'm back to loving my Pixel 2!
What adb command and what does it do?

you sure can, unlock your bootloader and install the latest 8.1 Factory Image from July, then relock your bootloader boot up and disable automatic system updates in developer options and hide the OTA notification by long pressing it.

Oh ok interesting. Maybe I was thinking you cannot downgrade from O back to N. I thought google made changes where you cannot downgrade due to security patches or something.
Oreo just has an overall more consistent experience and mature interface.
I never left Oreo for many of the reasons you listed, after researching Pie a bit.
We're stuck in this kinda bad phase of phones right now: manufacturers are removing hardware features to encourage/require additional accessory purchases and forcing obsolescence (or ~$80 for battery replacements), plus new software seems in a lot of ways to be regressing. I mean, if you have a Kit Kat device laying around, boot it up and I swear you'll wonder what the heck has "improved" since that. Imagine a Kit Kat style firmware running on today's fast RAM and processors, with hardware features - removable battery, sd card slot, headphone jack. Excuse me while I wipe up my drool.
I'm sure there are people that want AI and all that jazz, but I also bet there are plenty of us who want a stable, long-lasting dependable phone, and there just aren't many options for that anymore.

Ticker notifications are the best, and can get improved, there is an app in PS if you want them back.
Couldn't agree more with you guys. Pie is just terrible. I'm so happy to be back to oreo. Unlocked bootloader, back to oreo, relocked bootloader and turned off updates. No need to root, I couldn't get better than this and if I did root I'd lose Google pay which is awesome. No need for xda for a long time. Bye bye!
I admit that the battery was worse on the initial roll out of Pie. But I've stuck with it and this is my battery right now in the November update. I don't have or play any games on my phone though. I'm happy with it.

you can have the best of both worlds. root + unlocked bootloader + still use (most) apps like google pay that otherwise detect such things. all you need is magisk and to flash a custom kernel that disabled the bootloader check (i use flash kernel)

Thanks for your ROM it was probably my most favorite S4 one.
Also went back to 8.1. Only thing I really miss is the smart rotation option in the dock. What makes it worse is there is a bug in 8.1 where if you enable rotation via quick settings, rotate the device to landscape, rotate back to portrait, then attempt to turn off rotation via quick settings again, the first touch input does not actually toggle the setting, need to press again.
My other observations: Fingerprint sensor seems a little slower, charging sound toggle does nothing (known issue).

1) For me it's much preferred, I can always easily control media volume, which I do 9 out of 10 times, personally. I know that You might want to change the ringer to adapt to situation, but it's obnoxious to do it every time, why not leave it on an average setting or turn on vibrate mode for silent, for once a Android phone has a decent haptic feedback.
2) Go buy a Samsung, if You want "unprofessional". In real world it's called simple and intuitive, and Google IMO seems to be doing this even better than Apple ever did.
... no comment
6) Faster, yeah, but more fiddly, I found the new system more calming and it requires less tapping, and transition between apps and scrolling seemed smoother. But it's not perfect by no means.
...
9) Can't disagree with this one
agreed 100%. My battery life is so much better now that i'm back on oreo than i was on pie. on pie i had to charge 3 times a day when prior to the 9.0 update, i'd easily make it 24 hours no problem. i lost over an hour of screen on time. was pathetic. i'm done with pixels after this phone honestly; google is such garbage now. also incredibly ridiculous i need to run a modded APK to get night sight on oreo because they won't rollout the new apk to oreo when it's clearly all software that was available on oreo. i'm staying on 8.1 until i get a new phone, and with all the BS bugs of 9.0, i'm def not looking forward to 9.0 touchwiz on my work note 8.
Hi
I have just received the update notification that the Oreo 8.1 update is available to download,but when I click to download and install I just get the message....
Download failed,please try again.
My internet connection is fine,and I am not rooted...
Any help would be greatly appreciated.
My model is TB-870F
Thanks.
Oh well.....I’m stuck with 7.1.1 then it seems lol
Lenovo have pulled the Ota for the time being as it bricked a fair few so they are fixing it etc.

I would not be surprised if they paused the OTA rollout. This update caused a lot of mess when I upgraded my 8704X:
1) the notification area went crazy (netguard),
2) I lost application read/write access to my external sdcard (I only had read access to it through the built-in file manager) therefore I had to back up its content, reformat it then restore my files. I figured out it was likely due to a permission issue it would have been barely infeasible to solve without rooting,
3) the system application named after Mobile Services started to install apps I did not want,
4) had to clear both cache & data or reinstall a lot of applications which dysfunctioned after the update.
On the bright side, the update brought:
1) a smoother experience. The overall UI interactions seem less sluggish although not fast enough when compared with a SD835. Digressing: could we get a high-end 8-inch Android tablet any time soon?
2) application startup is fixed. Some of my applications (e.g. hangar, ampere) previously did not start at boot,
3) better integration with password managers thanks to Oreo,
4) native night mode (red light),
5) touchpal 2016 keyboard removal (I could previously only disable it).
Finally, my last concerns are:
1) my tablet still cannot act as a phone. The 8704X model may not be able to place a call or some tricky network conf blocks it or I got a defective model. 4G/LTE data works,
2) Oreo is probably the last upgrade and there is no alternative rom development running,
3) (minor concern) I cannot benefit from Netflix HD streaming despite I never rooted/flashed my system.
To conclude, I really feel depressed considering the Android tablet market.
1) I was never really happy after switching from my Sony Z3 Tablet Compact to Lenovo Tab4 8 Plus. Sure, the later is more powerful and has more storage capacity. But the screen is vastly inferior (blueish, ghost touch) and the development scene does not exist as of yet.
2) there are very few 8-inch tablets worth. The Huawei Mediapad M5 may tick few boxes (slightly faster cpu) but the WiFi/BT issues, limited storage options (32Gb max), average battery runtimes are not convincing.
3) the 10-inch offer may be more tempting if you are willing to accept this format, pay the price, and opt for Samsung proprietary interface (e.g Galaxy Tab S3/S4). You cannot obtain more than 4Gb RAM/64Gb storage though.
4) the Pixel Slate is barely a prototype, most users reporting Android compatibility issues. Intel-centric, indecent price, no 4G/LTE connectivity yet, no external sdcard means you must purchase the Core I7/16Gb RAM/256Gb model.
Apple/IOS jail not being an option, I will keep my tab4 for a few months.
I don't like or have a tablet. I prefer phones for everything. My moto z2 force is my favourite at the moment.
Got the tab 4 for the wife to watch zion on it. Sold a 2018 ipad 9.7 for it as she found it too big and heavy.
Oreo update (S001018) worked for me on TB-8704X, but dm-verity is making me nuts, since I cannot go make a backup of my data partition after boot because of forced encryption, which means I have to lose all my settings and apps whenever I want to restore to a previous state - factory reset - which for me is unacceptable. You cannot install Magisk before this happens, and what is rooting without the ability to back up even good for? So I am patiently waiting for someone to port LineageOS or another custom ROM that can liberate me from this mess. So sick and tired of the stock ROM and its limitations. Go to hell, mandatory boot sec-bullies!
Well.... I'm getting crazy with this crap. I can't access the SD card in the external apps (like Perfect Viewer). I tried to reformat it but problem is still not resolved.
If i knew the update should cause all these issues i wouldn't install it, too late now i guess.
Some issues i encountered:
*Es file explorer - disabled\being uninstalled after start up and my tablet is set for timed startup \ shutdown.
*Issues with built in alarm clock app, could snooze it with a shake and now it doesn't even shows the clock when you open the cover and turning it off is pretty frustrating if you want to turn it off quickly.
*BS player issues connecting to SMB home network pc and also, when skipping files it got stuck and needs to be restarted.
So if you read this before installing the update, I recommend to wait for a better fix.
Hey guys, I'm downloading Android 11 update on my N9860 HK note 5 as of now. At last
Congrats, man would you please check Android Auto in the car - does it work?
I didn't like the update at all - ugly interface and the phone is now freezing a lot even after wiping cache partition. The old Android was buttery smooth!
I also noticed that Night Mode takes A WAY longer to process the final image vs old Android that was taking just a few seconds. Can someone please check this and confirm for HK version?

I can barely notice a difference. No change in performance. No stuttering. The biggest interface change I've noticed is the style of buttons for the SIM unlock screen. Otherwise everything feels the same.
I tried a night mode photo. I'm not sure how quick it was before, but it seems what I would expect. Maybe any delay is due to superior processing.
Overall I'd say the upgrade experience is practically invisible unless you want to go ploughing through all the menus. I don't care to do that. I have no need to.
I'm curious to know from those who updated/flashed to the STABLE (NOT BETA, please!), how is your phone working so far? Do you have any issues? Were the issues from the BETA resolved?

I generally like the new animations, the new popup PiP design (rounded corner and possibility of resizing the window), battery life seems to be as good as before. The possiiblity of making AoD turn on when receiving a notification is nice and resembles the old Motorola active display feature. New Pro Mode layour for camera is better. I also enjoy the integration of the same animation for loading screen system wide, it's a nice touch even though I think the animation itself could be better. The gesture system from Google (Swipe from sides and bottom) now is usable with a 3rd party launcher, though it's still a bit clunky.
The only thing I dislike is the brightness bar in the notification tray which is now "tall" all the time and takes more space.
I must say that I didn't notice any particular difference coming from the second Beta (for Exynos there were only 2 beta releases), the first one was a bit clunky but the second was already well cooked. As far as I've seen there are no new issues introduced with this release, the 2 I knew of that were introducd with Android 11 still stand: Samsung gestures (swipe from bottom, the 3 way one) don't work as smoothly as in Android 10 because the recents gesture is not interactive and triggers only on finger release, the "currently playing" notification in the tray sometimes resets (when you reboot for instance it appears showing the last thing you were listening to).
Overall I'm happy about the update, it's a minor one for sure but they succeeded in not screwing up.

I generally like the new animations, the new popup PiP design (rounded corner and possibility of resizing the window), battery life seems to be as good as before.

Thank you for this, @Sprov!
How about on connectivity, WiFi, Cellular, 5G, WiFi Calling/VoLTE, don't you have any issues? Connecting to BT devices like Buds Pro or any audio devices, Google AUTO etc.?

Everything as smooth as always, now that I think about it I had to pair again the Buds Pro during the first Beta (it was working at the beginning though) because the media would play but there was no sound output. In my area there's no 5G to test. 4G and calls fine as before, WiFi, GPS all alright. I don't use Android Auto
I have two very annoying issues with One UI 4:
- Overheat
- bad animations (lag, fps drop and etc)

I guess the Swiss version won't work with BTU?

It works with BTU, in Odin use home_csc for retaining your data.
Clean install here and everything is smooth and I feel it have a better battery life then before..

I have same issue.
Hello ,
Exynos
Phone buy Samsung Shop web
Flash with Odin PC , Switzerland firmware
Just update , i became from beta 2 , i use home csc . I conserve all data
My phone is more smooth , more reactive . For battery , it's difficult to say it's more better . Good works .
Codec LDAC is functional since a few update , i like that with my Soundcore Life Q35 .
I like this update but it's not a big update .

Not sure about the high temperature, but I read in other forums that factory reset can't fix the laggy animations. I think for this we need to spam on Samsung Support. Also, I did heavy debloat with some PC app, and seems the battery life is drastically improved. I may share the result in a few days.

Does LDAC stick once it's enabled or do you have to keep enabling it? Do you also need to go into developer settings to activate it?
Sucks. On my Verizon it killed the top of the display; first row of icons. Posted a thread in Q&A.
My advice is: Don't!
Immediately used adb app control to kill updates.
Now what?
I'm still on beta three, I haven't had any issues with any of the releases myself 986U1 ATT
- Model: Exynos
- Branded
- Flashed
- Dirty flash for starters, then did a FULL reset?
- Issues: Lots of little ones, Bluetooth Buds continually disconnecting as well as Galaxy Watch 4, Alarm keeps turning off when hit snooze button instead of snoozing,Google Assistant does not always work with voice wake up, this is a problem when driving. Plus a couple of other small things I can't remember at the moment.
- What do you like, most things I like, Dislike that Android Auto for Phone screens no longer supported, have to use Assistant Driving Mode that does not work in landscape mode and is absolute rubbish.
I have now gone back to Android 11, till I see that these problems are fixed.
I did try the Beta version before the stable one, and that have most of these issues as well, so thought should have been fixed for stable release.

I'm curious to know from those who updated/flashed to the STABLE (NOT BETA, please!), how is your phone working so far? Do you have any issues? Were the issues from the BETA resolved?

- Model: Snapdragon/Exynos
