Hi there.
My problem is this. When you restart my phone works with about 1400mb free RAM. A few days ago I had to do in a short time many photos 20-25 in HDR mode. After 20 picture the camera kick me out, and when I looked at how much RAM I have, I found that I had free only 150mb. I noticed that when taking pictures of RAM consumption increases progressively with each shot, not once. Another thing I noticed that this consumption occurs only when taking pictures in HDR mode. When off HDR shooting mode there is no problem. Separately in the Running Apps nowhere figuring out what is currently using as much memory. When I reboot the phone everything falls into place, but every 20 photos i restart it, and I do not think that is normal. I would like to use HDR. My friends with* Nexus 4 have the same problem, which means that the problem is not in my phone. Can any of you to try and convince you.Before the update I had no problem with the camera and I hope you do not have to go back to the old camera. My question is there a way to fix the problem. Thanks and sorry for my English.
Unfortunately, Your friend and you arent the only one. I have the same problem with pictures in HDR and I am also on a nexus 4... :/
Same problem here. Also in photoshere, after 8-10 photos photosphere kicks me out. havnt still found fix to this issue..
After I took 20+ photos in HDR, free RAM was only 261 MB, and N4 was totaly slow. There sure are problems with google camera.
this is an ongoing issue since sometime now with no fix in sight.
My N4 restarts automatically after taking few shots. the same happens at times in other applications as well. so I don't think it's Camera application itself, but camera drivers or something which is creating the problem.
Yes the infamous camera reboot was supposedly solved in 4.4.3 but it appears that many are still having the issue. It is camera driver related and affects all applications that utilize any of the devices cameras.

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?

I used the temporary CWM method [GUIDE] CWM & Root Lenovo Yoga 2 (8/10/13)
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!!
THANKS!!!!!

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.
After using Galaxy S4 (I9500GT) for almost an year with lollipop, I recently shifted to Note 3 (SM-N9000). As S4 was a perfect companion performance wise, even in Power-Saver, I was expecting Note 3 be atleast the same if not better. However, I am facing a few issues mentioned below:
In Multiwindow mode, the video sometimes lag when I focus on other application. Then I need to restart the phone.
Sometimes while in fullscreen, with no heavy app in background (I play no Asphalt or Modern Warfare), my video starts lagging heavily.
Sometimes there is a slight Audio/Video sync issue.
I do not know what to do. Power-Saver turned off-on-off several times, no positive results.
The same never happened in my S4
NOTE:
I keep on changing ROMs, but I always clear everything and this happened on stock which I flashed through ODIN with "Erase NAND" enabled. So this is always a fresh install.
Please help
Also guide me on one thing. As I have used Samsung for years, I now know which apps to safely disable. On TouchWiz-Lolly, I disable almost 50 apps on my Note 3(like I used to do on my S4). So it is quite lag-free overall(except videos). Now I am getting a SoT of around 6.5-7.5 hours with 30-50% brightness. Disable every useless TouchWiz feature like sensors
I do not use location frequently, and keep switching between WiFi and 2G(Yes, 2G).
Is this battery performance decent, or do I need any more tweaks?
Thank You So Much For Reading
I use nova launcher, its way faster then stock samsuck.
Disable all animation, they add lag.
Video-Use MXplayer with hard acc ON, and same for bsplayer.
Regarding app , you mean unckeck from startup( like msconfig on PC) or disabled from ALL/APP?
From all/app disable only crappware like: yahoo new, bloomberg or something.
On startup app you need to unckeck them, with android tuner. Disable all games, and apps that do not need them in memory ram.
Even my tegra 2 asus sl101 tablet get some lag on video , but with hardware acc ON is quite ok.
My n9005 with lollipop is identical with wife n9005( 4.3 android) except one: lollipop start videos faster, in any video app.
Disabled from All Apps
Hi guys, I'm facing a weird issue and I can't find a way to fix it.
I own a Nexus 6p since september 2016 and it was all fine and dandy until I started noticing green blocky compression artifacts on some youtube videos (standard 2D ones). I initially though it was a connection issue (wi-fi or data network). Then i tryed to use the phone as a VR display with Riftcat and Vridge but I got horrible artifacts on the video stream regardless of the transmission method or codec chosen, I tried both wi-fi and USB tethering.
Now seeing that the issue kept going I tried installing the Within app from Google store and downloaded the 360 stereoscopic movie "Invasion!" on my phone storage and played it.
Green blocky lines are there, and it's not a network issue since it is now an offline file. They tend to appear along the "meridians" of the virtual sphere on top of which the 3d video is projected (it's not a display fault since these bands are not in a fixed position on the display, they are in the movie).
It certainly looks like a codec issue, almost like my CPU can't keep up with the data provided by the video file or the data stream.
Also the problem doesn't show if I use a realtime VR app like the Carboard demo, so it's definitely something with videos.
I tried monitoring cpu frequency with Cool Tool and the frequency usually ranges between 960 MHz and 1444 MHz during playback.
Is there something I'm missing? This phone shouldn't be that weak in decompressing videos.
I've recently received the Android N 7.1.1 OTA update, but I'm full stock since I bought the phone.
Any help would be appreciated.
Hi everyone ! Just wonder to know if anybody succeeded to use DJI Phantom 3 standard or other model with OnePlus 5 ? I have horrible lags on video preview of the aircraft that make impossible using the phone to control it... I've been trying for the past week, flashing different kernels, using different apps and was not able to make it working... Anyone that might have a fix ? ??
Due to his specs the OnePlus 5 should works perfectly... I can even make it working on my old Samsung Galaxy S5 and it runs smoothly...
I assume you have all power-saving features turned OFF
I assume you have the "developer options" for your graphics / animations on the phone left at stock settings.
Does the OSD (on screen display) for your battery life, altitude and those things update in real time smoothly while the FPV is lagging?
If so, then it is more like a Wi-Fi communication issue over that specific port. Ensure you have no security/ antiviral apps running that would be scanning these types of ports (or doing any type of deep-packet-inspection).
