It's probably because of Lenovo's horrible optimization of Android.. It would randomly start flickering the screen until i reboot, next day it would randomly drain a full battery in 2 hours and the next day it would just last like it should.. and the sound is horrible and Lenovo just plain denies it made it happen which it did in the last LP update.

No idea how to fix all this crap I don't think its fixable at all..

I managed to sell it and get a proper tablet in replacement and i reccomend you the same.

[Android Q&A, Help & Troubleshooting] Minto107:
Isn't iPad better? I've seen M1 in action... It only looks good trust me ;) from specs M2 looks okay, if I'm not wrong it's P9 cloned into tablet with much worse screen, but I would never buy Huawei(had P7 for a while, went back to S3, still have Huawei 4G router at home, Wifi suddenly drops, dunno know why it jumps from 4G to 3G so often...) so simply, buy Pixel C ;) at least it will get updates not like Huawei???

M2 has the exact same screen as this tablet. Are you sure that your not thinking about the T1/2?
[Android Q&A, Help & Troubleshooting] Minto107:
I used M1, I'm sure even checked photos on Web, I will check T1/2 not sure how they look but how is Huawei android update policy? Most of their phones get 1 update and some even doesn't gave any, specs look promising, if it would have cyanogenmod os in the future it might be a deal breaker for me. CM OS=endless possibilities :D
[Android Q&A, Help & Troubleshooting] JustPlayingHard:
Seeming as the M2 has the slightly older processor (one/two down from the Kirin 935) I think I'll be fine. But whatevs, I'm getting it for free. I'm not going to complain.

You can do "downgrade" - only. There is no Lolipop to flash, kitkat has another efi version.

So I sick of lollipop on this tablet s8-50L. How I report a few post ago I want to brick this device and send back to service to try to restore or swap device, who know.

I will try to update through OTA on Lollipop, people said it bricks for sure and then send to costumer care. If the assistance don't repair I can try to downgrade and restore kitkat.

Someone suggest to wipe everything with temp recovery and send it to service. In this case If there's no repair I can reinstall Lollipop or restore the backup, I think.

What's the best solution for you? Do you have any other suggestion? Thank you!
[Android Q&A, Help & Troubleshooting] Minto107:
They won't repair or replace it as they will see 3rd party software(SuperSU) installed, it's better to get back to kitkat

Kitkat - page 135.

Brick & service:

1. Temp twrp and wipe everything.

or

2. Downgrade to kk, oto to 1st lolipop, root, ota.

You can try also to delete default.prop using temp twrp.
[Android Q&A, Help & Troubleshooting] Minto107:
I wouldn't root firmware, they still have a look at system partition(correct me if I'm wrong, they will look for su libraries, it's typical these days. I would rather go for the first method you mentioned ;) it feels risky and I wouldn't wipe efs partition(not sure how it was called on this device)

if i remeber tight the supersu on lollipop it's installed trough temp recovery so if restore default setting the supersu should be removed.
[Android Q&A, Help & Troubleshooting] Minto107:
You mean factory reset? If so it's not that easy. Su binaries are in /system unless you're talking about systemless root but it's for Android 6.0/7.0(as 3 hours ago Nougat was released) only. To get rid of root you have to reflash firmware or do cleaning through SuperSU app but I'm not sure if it will work 100% and won't have some files in system

Is it possible to downgrade from lollipop back to KitKat?

I stupidly updated to lollipop finally the other day and I much prefer kit Kat. Volume controls are messed up, I liked being able to change the device volume from wherever, now I can only change the alert volume unless some media is already playing, and by that time it's too late.

The file browser app with the handy file transfer function for media is now gone and the one from this thread doesn't transfer the files.

I tried to flash KitKat back on, it connects but when it reboots I get some message about invalid target or something along those lines then it just boots normally and the flash fails.

Is there a way to get it back to KitKat?

I never actually use the speakers as i use headphones.So yeah I won't mind or notice the sound difference. And what about the performance. Is it the same or better ?
[Android Q&A, Help & Troubleshooting] FofM:
I didn't get to test Lollipop much, had it for a day but definitely the sound was somewhat distorted (on speakers, have not tried headphones). My tab stopped charging right after (not related to the upgrade) and when I had it serviced they re-flashed it with the latest KitKat update and said that's a recommendation from the vendor. I don't plan to upgrade back to Lollipop mainly because of the lower audio quality. Can't comment about other features as I didn't get to test it much.

I figured out the problem. And the culprit was....

...

Google Now Launcher!!!

I was using Google Now Launcher, because I thought it was cool. I uninstalled it, and I'm using the Stock Launcher3 since then.

And voila, battery usage when in Airplane mode is barely measurable. I lost 1% per night!

With WiFi on, battery usage is a little higher, but still a lot less than before.
[Android Q&A, Help & Troubleshooting] Minto107:
Hmm that's interesting, I also use Google Now as my home screen since lenovo dropped VibeUI in lollipop and their stock launcher is just ugly as **** and Google now is good since never hold home button didn't work to open Google now so I found it really useful and handy. I'll try some other launcher later and report back here...

Hi,

Few days ago I did downgrade to kitkat.

I had too much modifications - after factory reset brightness was always 100%.

I updated to the newest LL, full backup in twrp, root etc.

I did try some launchers, some apks, xposed (gravity box, boot manager, greenify etc.). Nothing better.

After my experiments i did restore backup. Now I'm using launcher 3, dpi 280, auto start manager, kernel adiutor (cpu 1330MHz), brightness 20-30%.

Tab needs few days to stabilizate.

Here are effects:
