I also went back to KitKat but I don't have that notification.

Right now I'm also on 4.4 but I think S8-50L has better firmware than S8-50LC. Also it worked a bit smoother as I remember and Dolby equalizer is lagging for me XD

[Android Q&A, Help & Troubleshooting] mcarans:
1. Can anyone explain or point to a step by step guide on how to install the Xposed framework on the S8-50F running Lollipop?

2. I am confused about what is the native dpi of the screen of the S8-50 tablet. On the Phone Arena specs site and Amazon UK, it says 283 (8-inch full HD (1920 x 1200) IPS (283 PPI) ), but the original firmware had it set at 240 and new one at 320. What is the real dpi of the screen?
[Android Q&A, Help & Troubleshooting] mac231us:
not sure about S8-50F but this worked for LL on the LC version regarding xposed

---sdk 21 is for 5.0.2 and for the x86

anyway as Shump posted earlier to someone else (not that you are guilty of not searching) but search the forum as there may be a better guide as mine might be confusing

[Android Q&A, Help & Troubleshooting] mcarans:
Regarding my question 2, I asked Lenovo UK, and they said:

"At 8" (20.32 cm) WUXGA (1920x1200) the screens native PPI would be 240"

I have made some steps below using various sources. Is this correct, in particular do I refer to the correct files eg. xposed-v79-sdk21-x86.zip for 5.0.1 (I don't have 5.0.2)?

1. Install XposedInstaller_3.0_alpha4.apk but do not run it

2. Run launcher.bat from IntelAndroid-FBRL-07-24-2015.7z

3. Follow the instructions in cmd window(enter "ACCEPT", selected preferred recovery, use option T4)

4. When the device is rebooted to fastboot, go to device managers and update the driver for the android device(some guides for the options: browse my computer for driver software, let me pick from a list of devices, select android, select Lenovo ADB composite). If all done well at this step the script executed earlier should continue and device should be booted to the temp recovery

5. Flash xposed-v79-sdk21-x86.zip

6. Reboot

7. Open XposedInstaller_3.0_alpha4

8. Install modules

EDIT -- Above steps worked for me --
[Android Q&A, Help & Troubleshooting] itasoulas:
About the first, I think 240 looks bad. Everything is so small. I use 283 which seems normal to my eyes. Online dpi calculator also suggest that value in relation with the screen resolution and size of the display. As for xposed framework, I use latest stable from xposed official site and never had problem on KK. But I just use XVolume module so I can have 30 or 45 volume steps.

Xposed? Only to change dpi?

You can edit /system/build.prop and change this line:

"ro.sf.lcd_density=***" I have 280.

Root needed
[Android Q&A, Help & Troubleshooting] mac231us:
yes xposed installation steps look right to me
[Android Q&A, Help & Troubleshooting] mcarans:
I use the Texdroider DPI app to change DPI (with root).

I installed Xposed, but it seems not to work so well. Greenify's auto-hibernation service stops and AppOpsXposed won't work either. Anyone experienced this?
[Android Q&A, Help & Troubleshooting] dzidexx:
1. I did set dpi to 280 - I think this is the best (for me, some apks work bad at 240,260 or 300).

2. Auto-hibernation - I'm using kernel adiutor to control cpu, https://play.google.com/store/apps/details?id=com.grarak.kerneladiutor&hl=pl.

and AppOps installer https://play.google.com/store/apps/details?id=droidmate.appopsinstaller&hl=pl.

I haven't xposed, only root
[Android Q&A, Help & Troubleshooting] mcarans:
2. I also use Kernel Adiator to reduce the max clock of the CPU. Do you have any other settings for improving battery life? Thanks for the App Ops link in Google Play - that one worked fine.

As for Greenify, I restored my backup without the Xposed framework and it still crashes, so that is a Greenify problem not Xposed. The AppOpsXposed module though did not work on the S8-50 but works for me on my phone (LG G3). So not sure if it was an Xposed problem or just the AppOpsXposed module.
[Android Q&A, Help & Troubleshooting] itasoulas:
Hey, I also use Kernel Adiutor. I set the clock speed to 1,5GHz. Actually the default clock speed is 1,3 and the 1,8GHz is the turbo boost. So no need to stress this to the max. I use ondemand governor and as for I/O Scheduler I use noop for both internal and external storage. For internal storage I set read-ahead to 512kB and for external 2048kB ( I hava a 64gb Samsung Evo+). I also set entropy to 1024 read and 2048 write. And that's about it!

how i installed xposed on my s8-50f:

1. download apk from official revo link (first link in google search with "xposed installer")

2. install the apk and open it

3. install the firmware. when prompted choose "normal method" not recovery

3. when finished it'll ask you to reboot your tablet : do it.

after that, xposed works just well (don't forget to reboot after each module install and activation!)

Hello!

Quick question... I have a tab s850L and recently upgraded to 5.0.1 :/ My device is not rooted, is it possible to do that now (root the device) if i am running lollipop? I found a file here with the name "Root_S8-50LC_tab" can i use this one? Or i will end up with a brick device?

Thank you in advance!
[Android Q&A, Help & Troubleshooting] itasoulas:
Happy New Year everyone! I am taking some time to review some of the things concerning TAB S8-50. Overall I am kinda disappointed at this device. A good hardware killed by bad software. After upgrading to Lollipop, the battery was worse, tablet was slower. The only 2 good things I saw was that I could finally disable hardware overlays and use CF Lumen to adjust the tint of my display which was yellowish and the second that I could use dropsync and 2-way sync when my entire dropbox was on my external SD card (something that KK won't allow to do so). So I went back to KK, battery was a bit better but I was missing those 2 things. Today I am returning back to Lollipop. Something I noticed on both firmwares is that battery on gaming is really really bad. Sometimes I give the device to my daughters to play simple kids games (I am talking about age 5 so no any hardware demanding games) and the battery last tops 2 hours. Pretty disappointing!!

So on Lollipop, the Android OS is very high on battery charts, sometimes on top. No matter how many apps I freezed (and I am talking about barebones situation), the Android OS was still very high up the list. So there's definately something wrong with the firmware. I consider selling it but this will only give me about 100 Euros which is very very low. I was thinking of Mi Pad 2. Xiaomi devices are awesome. My Redmi Note 2 has an average SOT 5 to 5,5hours which is pretty good over a day and a half period. But right now I cant afford to give extra money for a new device.

There is some love inside of me for this device still and I am hoping that Lenovo will at least update one more time with a bug-fixing update. Anyone got any news about this?

Ending this, this is my first and last time I am buying a Lenovo device. They really don't have a clue about software/developing. Such a pitty as this seems just another device to make money with 0 support.

You dont need to unlock bootloader unless u want to have custom recovery always installed and install custom ROMs(so far no available). But if u want to run it install:

Lollipop to ur tablet(000456 151016)

Intel ISOC drivers( https://software.intel.com/en-us/android/articles/intel-usb-driver-for-android-devices)
