So is the consensus - that I stick with stock - but update to the latest available and sort out the dpi issue with the link provided?

Are we sure this unit wont get marshmallow?

Again - I'm interested in as many opinions as possible.

Plus - if there are any useful links you can share with me - I would be grateful (is this the best thread for my original questions?).
[Android Q&A, Help & Troubleshooting] busyinny:
Well at this time your options of Roms are stock (as in lenovo) 4.4.2, stock 5.0.1 or building your own ROM for it. The chances of it getting marshmallow from Lenovo are minimal. I do not know whether Lenovo has taken an official stance saying no, but I am willing to bet 5-1 odds it will not.

Personally I am rooted and have installed a permanent recovery then flashed to latest ota update with a slight modification to the file to keep my ESP and droidboot intact from the previous lollipop ota. I am hopeful that soon someone from within here will release cm 12.1 or 13 for this tab so that it becomes even more enjoyable for me.

This thread has everything you need for this tab with links to the Russian forums for the rest of the files. The information is scattered, it will probably take you a couple of hours to power read through the 225 pages on a computer, but at the end you will be the most knowledgeable you can be, rather than being spoon-fed certain bits and pieces. The only other info you may ever want for the tab is a few pictures from the inside on ifixit should you need to operate on it like I had to on mine.

I like lollipop, but my family want to use this tablet too, and I do not like to have all information accessible to whole family. And reason two was problem with gps position button . I want turn on and off gps via one button, and not to going though settings. When you hold button in KK you will jump to gps settings, in lollipop you just turn it on and off.

After disabling all the bloatware apps my tablet runs way better on Lollipop than it ever did on KitKat. On KitKat everything was like a half second before it would respond.

This!

Not quite sure if it would make the tablet more snappier, but it sure would be awesome if someone could do it! I would even help, but I've got no knowledge in building a rom. I'm actually a designer but I could test stuff out.
[Android Q&A, Help & Troubleshooting] Minto107:
About gps. It's same for KitKat and Lollipop. You just toggle location on or off and it gets back to last used mode(in my case power saving one). About full multiuser support right now it's best to get back on KK or wait for CM12.1/13 ROM

[Android Q&A, Help & Troubleshooting] Capt Morpheous:
Okay - so I've opened the box - pulled out the unit.

A) Can I uninstall the bloat-ware without rooting it?

B) Should I backup KK somehow, before I proceed to lollipop?

C) Should I do lollipop OTA upgrade, or should I upgrade using a specific release (the LC version that I have read about).

Tab Details: S8-50F - 16gb - wifi only.
[Android Q&A, Help & Troubleshooting] Minto107:
A) you can't do so but you can disable it and some is delete able

B) there's no need to do a backup. There is full software on the web

C) i strongly recommend taking lollipop update and don't use software for LC or LC variant if your is F(L LC means you have LTE data or data and calls)

[Android Q&A, Help & Troubleshooting] Minto107:
Brightness works fine for me, sound isn't that bad I think but mostly I use headsets instead of speakers

What do you mean by that? We can unlock it right now.

Also I've found next lollipop bug not sure if it was also in KitKat but my Bluetooth headset(Logitech H609) has laggy sound when using 4G modem(yes I finally got my LTE USIM card :D) but when I turn airplane mode on and turn Bluetooth and wlan back on its OK... Right now even when CPU and IO is busy with moving 4GB of files is fine streaming music with about 5 apps in background (PS. Still getting decent battery life haha)

Unlocking is not the same as modifying. The bootloader may verify the kernel, but is the bootloader itself verified by the boot ROM?
[Android Q&A, Help & Troubleshooting] Minto107:
For sure I can tell you that we can run CM based using Lenovo kernel so at least we can play with system about kernel itself I'm not sure but balika011 has run his own so unsigned kernel without any problems so I think it's not a problem. Also when you have unlocked bootloader it means you can do everything. It's like US Sammy phones. When you unlock it u can use it with any USIM card and also flash whatever you like(same on Xperia devices)

I understand what an unlocked bootloader is. What I want to know is if the bootloader itself gets signature checked by the silicon during boot.
[Android Q&A, Help & Troubleshooting] Capt Morpheous:
I understand that there was an issue ith the DPI - but that was resolved both officially - and from a few posts back - there is a unofficial fix too.

For the screen brightness - is this something that everyone is suffering from - has there really been no fix (even unofficial?

With the audio - is it just volume - or something else - once again is there no official or un-offical fix.

I an really shocked to see these problems presenting themselves with Lenovo OTA updates - and clearly it seems - no patches being provided. What is going on?
[Android Q&A, Help & Troubleshooting] Minto107:
For audio i think that audio effects file from KitKat will help

About brightness there is a fix. Disable Intel security apps(it's not my fix but it worked for me, but on latest update this problem is not bothering me anymore)

About DPI the only way is to do it via both ADB and build.prop and you'll get real 240DPI.

About OTA updates. You probably never had a device from HTC. I owned HTC one V and one s and both got updates that ruined my experience with these phones. Of course not mentioning Samsung where if you get any OTA having non S or Note series phone is a miracle and even on S series there are some ****ed updates (eg. Android 4.3 update for Galaxy S3 family) so Lenovo isn't doing that bad job ;)
[Android Q&A, Help & Troubleshooting] TommyDN:
Using the kitkat audio files breaks audio totally. It's just Lenovo has screwed up with the audio and it's not really fixable in my perspective.

The brightness fix doesn't work on my tab also.

[Android Q&A, Help & Troubleshooting] Capt Morpheous:
I genuinely appreciate the input each of you are providing.

As it stands - I'm beginning to wonder if I should just keep it on kitkat - and use it purely as a media device - no internet browsing.

I have a number of other tablets to do that with.

Is this a good idea?

Does kitkat - have any issues - e.g sound or brightness etc. too?
[Android Q&A, Help & Troubleshooting] Minto107:
You need to change just Dolby things i think

If it really bothers you, you can go back on KitKat until everything gets fixed or for CM

KitKat has no bugs ;) it's very good but just change DPI to 240 and you'll be very happy with it ;)

Do we got more threads running with maybe an other rom (or in development) for the s8-50? Or is this the only one?
[Android Q&A, Help & Troubleshooting] Shump:
I don't think ART or Dalvik directly come in to play for the audio drivers. The audio drivers sit inside the kernel level of the software. The kernel is the lowest level of software that is responsible for directly interfacing with the hardware of the device. The audio driver is bundled inside the kernel. In order for the audio drivers to work on Kitkat and Lollipop it would come down to the kernel being compatible with both versions. However, I think our tablet takes a more complicated approach by integrating Dolby audio into the mix.

Could you just help me understand the DPI issue properly.

I haven't seen it so a short history/summary would be most useful.

I can't seem to get why increasing the dpi to 320 would be a bad move - surely it would mean that this improves the quality rather than reduces it?

And on kitkat - would I still need to change the dpi to 240. Would it not come fresh out of the box like this already?
[Android Q&A, Help & Troubleshooting] Minto107:
What? Improved quality? You see less on screen. Everything is bigger on screen. It's like lowering your PC resolution. After taking any KitKat update you will have 320dpi

No offence and I agree with Minto...believe me for the LC if using the cellular capability better off with KK.. you can try but am afraid you may be one of the many coming back for help and then getting stuck on 'downgrade' to KK. Honestly, there have been so many folks wanting to get back to KK though they seemed to be spread across variants...as an LC user the biggest gripe I have with LL was the sluggish horrible keyboard on LL...even after the latest update... am pretty happy with KK...but no harm in trying LL out...

Thanks for understanding me mate ;) yeah when you enable 4G streaming via Bluetooth is stuttering, keyboard is laggy and tablets is overheating much.

I've had lollipop on my tab for a while and I've come to the following conclusion:

It sucks.

The tablet was barely usable since it was always dead cause system ui was draining the battery and the ui lag was just unacceptable. I'm not even gonna bother to talk about the sound quality.

I've installed kit kat (the first version with no DPI change) yesterday and it's been buttery smooth ever since. And the battery is not that bad either. I've also found out that the 3D performance is on par with android L (check the screenshots)

Benchmark tests:

Run 1

[Kit Kat]

[Lolipop]

Run 2

Run 3

If lenovo ever releases an L release with no issues mentioned above I might upgrade

I want to update the forum, and thank members that recommended I stay on kitkat and avoid lollipop.

This tablet has been working perfectly, the sound is great and the usability excellent.

Battery is poor (i'll admit), but overall I'm happy to hang onto it and use as a media device. I've also come across many threads that criticise how thin the glass seems to be.

I'm asking for advice and opinions on cases.

I travel alot and would like a reasonably protective case, with looks that are appropriate for a for a corporate professional. One that protects it while i store the tablet on my internal glove pocket on my coat (the device does flex a little to easily).

Any suggestions/recommendations/opinions welcome.

I have this leather Case: www.amazon.de/dp/B015FYJ0QK/ref=cm_sw_em_r_mt_dp_BNomxb0KKWM2S

(Be sure to pick the right Module).

It looks professional, the protection is good and it has stands for vertical and horizontal.

The downsides are that swiping "from the edge" is difficult,because the edge is covered with a leather rim. Also, if you put the front cover exactly behind the back cover when using, the magnet makes the tablet think that the cover is closed and turns off the screen. This is not a big problem in practice, however.

I have the Fitian case. The front cover is stiff and thick which provides more protection. However, it does make the entire tablet + case thicker which could be a problem if you want to keep it thin. For me, I wanted protection more than anything else. Also when taking flash pictures, the LED will bounce off the case and cause a tint to the picture. My case is blue and the pictures have a blue tint with the flash someitmes. However, I usually use a real camera of my cellphone for pictures.

You have to search it under Amazon yourself. XDA will not let me post a link because I am new to XDA and have too few posts.
