nice tab

Just picked this up the Lenovo Tab S8 Android tablet tonight. Did the update first thing, then rooted it ( thanks for the help rooting ). After I did that, I used Titanium backup to backup and then remove a couple of apps.

If Lenovo does release a Lollipop version of their ROM, hopefully restoring from the app backups won't be needed, but just in case.

Overall, mostly happy with the purchase, saved $40 off list ( US ) but I really liked the size and weight is why I went after it. Also wanted to give the Intel quad core a chance on Android.
[Android Q&A, Help & Troubleshooting] theoblackhawk:
Yes, I had the last update and the DPI changed so I rooted and did that.

Two weeks now and no problems at all so far...

Nice to see that helped you :)

The "latest version" that you mention it is the "stock", only difference is that if you root before update you will lose root permissions and will have to root again.
[Android Q&A, Help & Troubleshooting] PurpleKitti:
Apologies, I of course meant the stock version that came with it (which was linked somewhere in the thread) as opposed to the updated version. Silly me!

Thanks again ?

i set mine to matchthe ppi which is 283 but 240 works great too. what firmware are you on mate
[Android Q&A, Help & Troubleshooting] dwcasey:
Me personally, I don't need any of those and I guess the majority of people don't either. They probably come in handy for fitness, star watching, etc.

I noticed it lacked an ambient light sensor, but again, I'm fine to set a brightness and leave it.
[Android Q&A, Help & Troubleshooting] jazzespresso:
that's what I thought...it just latest firmware mistakenly puts 320 dpi... I download previous firmwares and checke build-prop and all says :

ro.sf.lcd_density=240

so this is true DPI for this tablet.

Standby battery time under low usage?

Hi,

Hoping you can help....

I have an A8-50 at the moment which gives amazing battery life - over a week with light usage (e.g. 60-80mins a day video watching) - but it has a built in Power Manager app that I use. I checked the S8-50 instore today but I could not find any equivalent Power Manager tool.

Also, on the A8-50 there is a Scheduled Power-on / Off feature built in which I use to auto power down in the evening and back on in the morning. I could not see anything similar on the S8-50 - but I only spent a few minutes looking.

Can you please confirm if the S8-50 has either / both of the above? Or are you getting 20+ hours without using any of the above?

Also, If anyone else out there has the S8-50 who is a light user - can they confirm how long it goes without a charge?

I like the A8 because my previous Nexus 7 2012 would need a recharge every 2-3 days even with my low usage - whereas the A8 goes a full week with my usage pattern. But I fancy upgrading to the S8 due to the nicer screen.

Thanks in advance for any replies!!
[Android Q&A, Help & Troubleshooting] jazzespresso:
the one they posted is for rekaveri on S8-50F, whatever it is, I believe it is ported from Russian firmware, so outside that it does not work for us.

without custom recovery (twrp), I am not seeing a lot of custom ROMs for this tablet.

---------- Post added at 11:27 AM ---------- Previous post was at 11:25 AM ----------

the latest firmware, I don't see Power Manager app comes with it. I am on TABS8-50F_141103 firmware.

---------- Post added at 11:35 AM ---------- Previous post was at 11:27 AM ----------

icon size usually related to stock launcher itself, current stock lenovo launcher's icon size dpi set to 54 ( <dimen name="app_icon_size">54.0dip</dimen>), which a tad big for this screen resolution.

but if you use Nova launcher, you will realize that icons get smaller it is because Navo adjust automatically based on your current dpi settings.

system dpi usually effects to games and videos, and apps..but considering that we switched to default DPI (which Lenovo messed up with latest update), I believe all should work as intended to.
[Android Q&A, Help & Troubleshooting] harryw66:
Thanks for the reply.

They had one in stock locally, so checked it out, loved the screen and bought one anyway!

Just did the upgrade to latest firmware using the Lenovo Smart Assistant but it got stuck on reboot and I had to manually select the update.zip using the volume + power keys. It then seemed to run through applying the update, but still reported some error.

The root seemed to go OK and have amended the prop file - all seems OK - but still not sure if the firmware upgrade was FULLY successful, certainly the firmware version has changed...
[Android Q&A, Help & Troubleshooting] dwcasey:
Harryw66, I am not aware of any power management software on the Tab-S8. It is very sparse on software. My guess is if I used this occasionally throughout the day and not for hours at a time, it should be realistic to get several days.

I've only disabled/uninstalled four programs since rooting and none of those were related to power management. It's possible there is some power management software under the covers as part of the Intel chipset??

The Google Play store has many power management apps, but I tend to stay away from those.

I just received this

http://www.amazon.com/gp/aw/d/B00O60L7UW/ref=mp_s_a_1_2?qid=1417647218&sr=8-2&pi=AC_SY200_QL40 case and for the money, not bad.

I'm not a fan of the shiny fake PU leather and the magnetic closure may be generating interference at times, causing the display to shut off, but I can't confirm yet.

The case holds the tablet in real well and it does make it easier to hold with one hand.
[Android Q&A, Help & Troubleshooting] jazzespresso:
this looks nice....looking for a case for it too.. a lot of this kind of magnetic closure causes screen on and off, which eventually dries out your battery...

let us know if you experience this with this case...
[Android Q&A, Help & Troubleshooting] harryw66:
After trying a similar looking 3rd party case, I eventually bought the official Lenovo case for my A8 - which did NOT have the magnetic closure http://www.amazon.com/Lenovo-A8-50-Folio-Case-888016506/dp/B00JN4TP9G

A number of us bought the A8 at work and the others also tried similar 3rd party cases from Amazon - however, they were all considerably bulkier than the official Lenovo case. The official one adds minimal bulk to the A8 and I could still fit the tablet with the case into my suit pocket. I could not manage that with the 3rd party one - which made it difficult to use on my daily commute which involve platform changes etc.

The S8 version is mentioned on the Lenovo UK website but no details as of yet:

http://shop.lenovo.com/gb/en/tablets/lenovo/s-series/s8/#tab-accessories_-_services

The current plan is wait a bit to see if the S8 version is release soon. Since the S8 back is not as slippy as the A8 back I am less worried about dropping it.
[Android Q&A, Help & Troubleshooting] jazzespresso:
I actually knew that I am going to have problem finding a good slim case for it as this tablet (S8) not wildly popular like Samsung devices. Even getting root was quite difficult as discussed here in this forum. It was just BestBuy has it for $150 for thanksgiving weekend sale, so I could not resist because this tablet's specs really good for the price of $150. My wife actual wanted to iPad Air, but after she played with this tablet, she said OK this is good...so thought it was not completely waste of $150!

Hopefully Lenovo releases case for S8, like they have for A8...if not, i will still check out 3rd party cases...
[Android Q&A, Help & Troubleshooting] dwcasey:
How can you tell if the case causes issues? The only test I could think of is fully charge it, then leave it unplugged without the case. Then the next night I could charge it up with the case on.

---------- Post added at 11:23 AM ---------- Previous post was at 10:49 AM ----------

I did the BB deal, too. I also got the $22 64GB micro SD to go with and the tablet still cost less than $200 with tax.
[Android Q&A, Help & Troubleshooting] jazzespresso:
you got better deal! hah hah hah...nice...

tell if the case causes issues, just fully charge your tablet, and leave it close and don't plug it...wait for several hours....then check battery status and see if it is goes down like %20-30

usually in most cases, tablet goes into deep sleeep, means avarage batter consumption very minimal, but because of magnet case fault it may drain much faster since magnet may cause wake the tablet from standby

making sense?
[Android Q&A, Help & Troubleshooting] dwcasey:
Sounds good, I'll do that this afternoon. Thanks for the tip. I will say the case is heavier than I would prefer, but it holds the tablet solid and seems well built.

[Android Q&A, Help & Troubleshooting] dwcasey:
It's probably as slim as you can get with a hard plastic back and a tacked on fake leather cover. I'm warming up to it, although I prefer to let it be case free as well.

Xposed Warning

Hi all,

Now that we have root, some of you may be thinking installing xposed stuff, - you may gone thru installing busybox, and xposed, but be very careful that some of xposed apps causing tablet softreboot or even bootloop.

I installed advance reboot xposed, which caused softreboot, and tablet was gone into bootloop, so I had to do data factory wipe thru adb shell command.

because we have no custom recovery, there's no way to make full nandroid backup for restore, so do backup your tablet's apps in different way, so you won't be sorry after factory reset.

Remember that this tablet has intel processor, and kernel is based on that...means many root apps may not work correctly and cause tablet crash..so be careful.

[Android Q&A, Help & Troubleshooting] harryw66:
I am quite low usage user - only tend to use my tablet for watching videos on my daily commute etc.

I managed to get 3 days and 15.5 hrs out of the initial charge before it dropped to 19%, with about 3hrs of video watching and therefore 3hrs of screen on time.

This is clearly not as good as the A8 I am replacing which would typically need charging just one a week with approx 4.5hrs video watching. But, then this is slimmer, narrower and higher res screen so I guess the battery cannot be the same size.

Note that the 3days 15.5hrs is with the tablet in airplane mode pretty much most of the time, except for a bit of updating and app installation etc.
[Android Q&A, Help & Troubleshooting] dwcasey:
Would be nice to get 3 to 4 days, but compared with the tablets and phones I've used lately, I'm happy to get two solid days with moderate to heavy usage. I keep the brightness way down ( Its just too bright for my eyes above 15% or 20% ) and WiFi always on.

If we get a custom ROM and/or kernel, might be some throttling to help a little, but most of my usage according to the battery setting is to the screen, so I just don't think it would help much.

I tried to put another ChromeWithBrowser.odex there, but it appears to perform a checksum match and it's not matching the Lenovo version.

edit: from what I'm reading about other phones/ROMs, there are many apps in /system/app that folks usually clean up, so I don't think it's necessarily a "Lenovo" version of the Chrome browser, simply the stock KitKat 4.4.2 Chrome browser.
[Android Q&A, Help & Troubleshooting] Jabberrr:
Awesome! Thanks.

By the way, I took a quick look at your build.prop and it looks like you changed your lcd density to 240 as well. That will most likely need to be changed back to 320 if you want to do the update since the hash won't match if it's set to 240.

Here's the ChromeWithBrowser.odex: dropbox[dot]com/s/f5jsfbe6ss4w51j/ChromeWithBrowser.odex?dl=0
