Did you give the one I posted a try? I have been playing with it since I set it and I haven't noticed the flicker yet.

We do not have the sensor activated on our tablet but I do think the hardware is there, it may be something with the chipset or something.

The ROM may have auto-brightness "stuff" in it but it is not connected to the sensor. I am wondering if the connectors will be connected after Lollipop is released someday.

The app I posted above maybe attempts to "take over" for the stuff in the ROM that handles auto-brightness but since there is no sensor it just sits on a level, at any rate it doesn't seem to be flickering. It's a free app and it's worth a try, others may work as well.

I feel your frustration, I hate paying for a product and then it has issues, I work hard for my money and I'd like to see companies I pay for the products support the products. But....that's why we are here, for community support, and the community is way more responsive than any company could ever be.

Installed the KK launcher.. reviews suggested its better than Google now. Its good and its fast/light but it does crash at times..

Try Apex launcher, it's a good one with lots of features and customization.
[Android Q&A, Help & Troubleshooting] pdxesto:
I also like Apex a lot. I went through many launchers before settling on Apex.
[Android Q&A, Help & Troubleshooting] KainXSS:
swapped my tablet 2 weeks ago and it came back 2 days later(after recharging), but I'm thinking its related to battery also, as soon as the battery hits 40% for me it starts the brightness issue randomly but never above 50%, it was the same on the previous tablet. so I looked around the rom and I only see some permissions relating to a possible light sensor and some basic stuff in the init files, basic stuff, but it does not look like auto brightness via sensor, it looks more like brightness throttling is occuring because the screen is either drawing too much power or some other battery/temp issue, the thermal_throttle_config.xml might also be worth looking at also.

would really like to check if there is a light sensor but theirs a warranty sticker on one of the screws on the board and I don't want to invalidate my warranty so I'm going to wait until the FCC releases their internal pictures next month before I start thinking of a rma or something since I can't take it back now.

has anyone else taken a look at other possible causes of this problem.

gonna keep looking though, maybe its something else

I also use Apex, Nova is faster but Apex just feels like a more stable, higher quality launcher.
[Android Q&A, Help & Troubleshooting] Phartus_Maximus:
My problem with the brightness cycling from dim to bright has solved itself it seems. No thanks to the monkeys at Lenovo on Twitter and their forums who keep saying to read through their forums insulting my intelligence along with everyone else they replied to with the same answer. All I did was wipe the battery stats and fully charged it first with the device powered on then fully charged it with the device off. I'm not sure if that is what fixed it but all I can say is that the problem has completely disappeared for me. I just hope it doesn't rear its ugly head again.

I'm using Nova launcher btw. Apex is very nice but I ran into the brightness issues on Apex and the stock launcher and even the poor GEL launcher. As I said I'm not sure entirely what the cause of this issue was/is but just thought I'd point out my settings/launcher and whatever I experimented with to finally rid myself of the brightness issue...I hope.

Definitely one of the strangest issues I've ever come across on an Android device and is very hard for me to pinpoint what the cause of it actually was. All I can assume is that is some sort of built in power saving feature that they introduced which was bugged/broken or shouldn't have even been in there in the first place.

Good luck with fixing your problem because I doubt Lenovo will help you.

P.S There's an update coming to the tablet on the 24th of January apparently if you read through their forum. I won't hold my breath or expect anything on that date. I just think that poorly of Lenovo after all of this and trawling through their forums and encountering numerous people with the same problems.

so you are on latest firmware, I am still on TABS8-50F_140929 - when I bought it, i knew people having issue with latest update (DPI mess, some performance issue, etc), so I freezed the system OTA update app, and never update it.

i wish you can able to dump system from S000185_141203 and upload it somewhere for me to download, so I can compare it with TABS8-50F_140929 system dump...i may able to see what diffrences...not sure that...

You might want to be more specific if you want help. Try reinstalling it.
[Android Q&A, Help & Troubleshooting] WildVenom:
Hello everyone,

Again some questions:

1. I can't make the Disable HW overlays option permanently checked. Whenever I close the settings app from recent apps, it automatically changes back to unchecked state. From what I have read it should be able to retain its setting until I reboot the device and not just reset after you close the settings app. The other settings in the Developer Options remain unaffected. This is only with the Disable HW overlays setting. Is it only my device or you face it too? Is editing build.prop risky?

2. Burnt Toast does not work on my device. ButteredToast works fine. Any alternative to Burnt Toast?

Watched the Windows 10 news today. Got me all excited! Don't get me wrong, I am completely happy with Kitkat. That said I was just curious, is it possible to boot Windows from a 64GB card on this device? I know that it is missing the necessary drivers and functionality at BIOS/UEFI level. Maybe its possible for Yoga Tablets. Has Microsoft and Google put enough restrictions in place to make this impossible?
[Android Q&A, Help & Troubleshooting] icanttinkofaname:
Your first two issues, I'm not sure I can help. Try fiddling around with the smart video setting before tweaking HW overlays.

As regards windows. dont hold your breath. There are barely any devs working on android for this tab. dont expect them to make win10 available.

If anyone has tried installing TWRP for this, I'd be interested to know how it turned out. Specifically if you used it on the S8-50F (wifi only version).

As I stated before, I had success using the root exploit, but I've been hesitant to act as the guinea pig because I'm not sure that there is a path back to stock in the event of a problem.

Should a recovery like TWRP vary wildly between the wifi and LTE variants of this device?

I thought that was just a DPI scaling change? Before the fonts were so small that it was incredibly hard to read and I was under the impression that they altered it on purpose.

I'm one of the people that got hosed by this update. Resolution is all wrong now, and very annoying. It's still under warranty and they say I can send it back in to be reset to an original version of the OS and not sure I want to do that. Would rooting it and installing a stock android install solve this, since it seems to be driven by the newest software update? I don't know much about messing around with android OSes.

[Android Q&A, Help & Troubleshooting] theoblackhawk:
So, this ROM that you uploaded is the one with the right resolution (1920x1200)?

How can I flash it back to the device?
[Android Q&A, Help & Troubleshooting] theoblackhawk:
Well, since I really liked this device and was not keen on to give it back I tried a last effort and voilà! I have the tablet back to its "default" state

All I did was root with the russian forum method and download the ROM Toolbox Lite app from play store to change the DPI in the build.prop file

The difference was that I used the "official" driver from Lenovo website, since I'm not a big fan of install those driver packages found on the internet

So if anyone wants to do the same (specially the ones that can't give the tablet back to the store), here are the steps:

1. First of all plug your device via USB to the computer with USB debugging off, this way windows will install the "normal" driver

2. Now unplug and install the Lenovo Smart Assistant software directly from the official website

http://support.lenovo.com/ie/en/products/tablets/s-series/s8-50-tablet/downloads/DS101291

3. Start the Lenovo software, activate the USB debugging on the tablet and let the program install the right drivers

4. When finished close the Lenovo software and run the root file from the russian forum

http://rghost.net/59210332

5. After the root process the device will reboot by itself and then boot already rooted

6. Install the app ROM Toolbox Lite from the play store

https://play.google.com/store/apps/details?id=com.jrummy.liberty.toolbox

7. Use the app to edit the build.prop file and alter the line ro.sf.lcd_density from 320 to 240

8. Reboot and that's it!

Remember, this was the method I followed and I can guarantee 150% that this works with the S8-50F model
[Android Q&A, Help & Troubleshooting] mattneilj:
Thanks for the help.

I now have the stock recovery back!

Still rooted on latest firmware and have changed DPI back to 240 - all is good!

[Android Q&A, Help & Troubleshooting] KainXSS:
Windows is possible on these tablets but the problem is as said before, intel tablets just do not get as much development and even though Lenovo could very easily bring over windows to this tablet(since the yoga tab 2 8 already has it and has similar core hardware) they would never do it, look at the last update -_-.

also I had a problem with audio through the headphone jack being too low, if you want to boost the audio on these tablets all you need to do is edit the AudioConfigurableDomains.xml and optionally the Realtek_RT5640Subsystem.xml for even more gain(dangerous though) editing both files can cause you to bootloop if you do it wrong but you can just back them up to your desktop beforehand and then boot into cwm and push the files through adb to fix the bootloop if you have that problem. I would not mess with the speaker gain though.

it also seems that the apk/jar files have the classes.dex inside them so if you want to you can just delete the odex files on the updated firmware for the F to get more room on the system partition, I want to eventually repartition and add the extra space to data though(freed about 760MB so far).

and after about 2 days after editing the thermal_throttle_config.xml to fix the brightness problem, I have not had the brightness problem since editing it:)

all you need to do is backup the original file then use an editor on your S8 like xplore and find this text and change it

from

<CDeviceName>Display</CDeviceName>
<CDeviceID>1</CDeviceID>
<CDeviceClassPath>com.android.server.thermal.BrightnessControl</CDeviceClassPath>
<CDeviceThrottlePath>none</CDeviceThrottlePath>
<ThrottleValues>
<ThrottleNormal>100</ThrottleNormal>
<ThrottleWarning>40</ThrottleWarning>
<ThrottleAlert>40</ThrottleAlert>
<ThrottleCritical>40</ThrottleCritical>

to

<CDeviceName>Display</CDeviceName>
<CDeviceID>1</CDeviceID>
<CDeviceClassPath>com.android.server.thermal.BrightnessControl</CDeviceClassPath>
<CDeviceThrottlePath>none</CDeviceThrottlePath>
<ThrottleValues>
<ThrottleNormal>100</ThrottleNormal>
<ThrottleWarning>80</ThrottleWarning>
<ThrottleAlert>60</ThrottleAlert>
<ThrottleCritical>40</ThrottleCritical>

make sure permissions are the same as the original file

reboot

if this is your problem basically your changing it so that when the cpu hits its warning temp it throttles the screen brightness down to 80% then 60% then 40% instead of just straight to 40%, I use 90% instead of 80 though.

this is how its done on the Yoga tablet 2's also, but they did not do it to the S8's yet it seems.

New update out - TABS8-50F_S000200_150121_ROW.

According to Mikhei777 at the Lenovo Forums: "Density is still 320 but if you changed it using adb it'll stay changed; Wi-FI n mode now works, intel graphics libs updated and some small changes in apps. Yes you'll have to reinstall ROOT if you want." - http://forums.lenovo.com/t5/Lenovo-...pdate-changes-resolution/td-p/1825209/page/19

The update removes root so you'll need to root again. After rooting, re-install SuperSU from the Play Store, update it, and you should be good to go.

[Android Q&A, Help & Troubleshooting] WildVenom:
Yeah right. Maybe in the future someone would release a device that can dual boot Windows and Android. Also this is probably the reason why we would never see a Nexus tablet with an intel processor. Too bad because I think Intel will come out at the top with regards to mobile processors in the future. They really have superior fabrication technology. Anyways we really needed a third competitive player in the market and with Windows 10 maybe Microsoft is it. But I really don't like where these OSes are going (Windows, Android, iOS etc.) they are just turning into these very sophisticated data mining softwares that you can't escape. Every device is being tied to an online identity, an account, most of the functions requires internet connection, every activity is being tracked and there are no opt outs. Heck I can even see Google releasing a Calculator app in the future which tries to make sense of what you are calculating and serves you ads based on it in your browser. Oh well I surrender to the Skynet. :silly:

Hi,

My apologizes if this has been posted elsewhere and I missed it.

The update from S8-50F_S000185_141203_ROW to the newest update failed due to checksum on the build.prop.

It's rooted and I only changed the density so looks like I need the build..prop from S8-50F_S000185_141203_ROW.

Anybody have this and what procedure do I use to replace it? The tablet is rooted using the Russian root.

Nothing else has been changed.

Hey Gary,

Here's a copy of the stock build.prop from 141203: https://www.dropbox.com/s/qrktvw3yet6j8kj/build.prop.20141203?dl=0

DO NOT FORGET TO CHANGE PERMISSIONS AFTER YOU RENAME THE ABOVE FILE TO BUILD.PROP. The permissions should match whatever the current build.prop has (644 if I remember correctly but double check just in case).

Copy the stock build.prop to the tablet using Windows Explorer. You can then use something like ES File Explorer to copy the file from the tablet into the system folder. As mentioned above, don't forget to set the correct permissions on the file after copying.

Alternatively, you can also use adb to push the file directly to the system folder.

Thank you very much that was fast.

I copied the file, set the permission, then did the upgrade. Worked fine.

After reboot I used the Russian root and installed supersu. So far so good.

Then I used Rom toolbox, made a backup of the build.prop, then changed the density to 240. SUCCESS!

I am very grateful for your help,
