Gonna try that,

Have also been looking for ways to make battery life better, one way I think is the IGP, on the Z3745 the default frequency is 311Mhz - 778Mhz but Lenovo(and many other companies) change this to 578Mhz-778Mhz it seems on the S000200_150121 firmware(did not check the older ones)

You can confirm this by running

cat /sys/class/drm/card0/gt_cur_freq_mhz (shows current IGP frequency, will be 200Mhz when sleeping)

cat /sys/class/drm/card0/gt_min_freq_mhz (shows min IGP frequency when not sleeping)

cat /sys/class/drm/card0/gt_max_freq_mhz (shows max IGP frequency when not sleeping)

you can also try to change the frequency back to 311Mhz(kept resetting back until I used an init.d script to set at boot)or underclock the IGP(works) by running

echo 311 >/sys/class/drm/card0/gt_min_freq_mhz

echo 578 >/sys/class/drm/card0/gt_max_freq_mhz

or

echo 667 >/sys/class/drm/card0/gt_max_freq_mhz

This obviously will reset upon reboot but thats nothing a script won't fix, every little bit helps

hmmm...I may add that to JazzROM, I actually added your brightness fix too....whatever hack we can add, it will help...

but this tablet's battery not awfully bad actually...of course it all depends on how to use....
[Android Q&A, Help & Troubleshooting] Brecht35:
Hello guys, is there already a fix for the brightness problem? My brightness changes constantly when running certain apps. It's really irritating, it changes every 5 seconds..

If there is not a fix, then I will have to return the tablet to the store I'm afraid.

Edit: My fix(seems to work so far): Set brightness to 30/40 percent in your settings. Install power toggles, disable auto brightness, delete the last brightness setting(there are 3). Now you have all my settings and it seems to work so far.

Hi all

Got this tablet few days ago and its great.

And i have a issue with camera (I tried 3 different S8-50F in store and all have same issue but i still got 1 for myself)

Here is the thing.

1. When you open camera and want to take photo all is great.

2. Swap to video and you have zoom like 2.5x (as a default) or more (you cannot un-zoom, only more zoom up to 6x more)

Called Lenovo support and they have no idea how to help except send us brand new unit for service but what about rest of those two i tried in store with same issue should Bestbuy send them too

Is there any settings that can be done or any app that i can use for video recording.

Can`t post links yet (need 10 posts :) )to show pictures of what i am talking about for better understanding.

Thanks

I just tried it and it shows it as being 1.0x, however the screen looks more zoomed in than it is when taking pictures. Is this what you are referring to? Or are you saying that the zoom actually says 2.5x when you switch to it? Because, that isn't happening to me at all.

download and install this as normal app

This is default camera app and gallery from Yogo Tablet Pro 2, which is also intel base (x86) tablet.

once installed, find camera app and give a try.

p.s: it has similar app icon, so make sure you are testing this app, not the one comes with stock..

it works perfectly fine for me...

I just tried yor app and its working OK but I still have the same issue.

For some reason default zoom is set to x2 or more on video recording I dont know what else to do.
[Android Q&A, Help & Troubleshooting] spring%2000:
Hi I think it has something to do with the resolution of the video. It only uses the middle of the sensor. The full sensor is too high a resolution for HD video. If you change it to a lower resolution you will zoom in even more. You cannot do much about it. It is all to do with the size of the camera sensor size

Hope this helps

[Android Q&A, Help & Troubleshooting] feanor997:
Well that make sense but when you consider phones and other tablets with same camera resolution or greater and they have no problems like that.

Yes I did try change resolution and 1080p - 720p have same zoom lvl

But 480p have a little more zoom

I am convinced that lenovo did some wrong setting

Anyone notice muffled and noise issues with the microphone? I have two of these tablets and when doing a skype call, they both make loud & harsh noises due to the microphone, even if I keep the tablet still and don't touch the mic area. If I plug a headset in and talk, the other person can hear me fine. But it's a pain that the built-in mic has such noise issues.

Any advice would be greatly appreciated.

Any roms for this tablet? And will it ever see lollipop?
[Android Q&A, Help & Troubleshooting] sirxdroid:
Mine reboots every time after it's charged. Or maybe it happens while it's charging, I'm not sure as I charge it at night and find it in the morning rebooted waiting at the boot prompt for the encryption passphrase (I turned encryption on on mine). Any ideas what could be causing these reboots and is anyone else seeing this?
[Android Q&A, Help & Troubleshooting] KainXSS:
yup I noticed that too, sometimes but not everytime overnight it will reboot and when I get it in the morning some of the battery is drained

I did notice the screen-flickering on spotify, then kept getting the washed out looking colors on videos with that ugly sharpening effect every now and then and did not know what keeps causing it, but guessed it was the Content Adaptive Backlight Control doing it since one the yoga tab 2's has a problem with it(this is disabled in the build.prop so wtf), so I decided to partially ported Synapse(the UKM init.d trigger version by apb_axel) and added a control for CABC. Enabled CABC to see if it had the same ugly effect and yup it did, washed out colors and sharpened screen, still don't know why it keeps turning on for me but its verry very annnnoying. Other things seem to trigger it also so Lenovo should fix this before they release lollipop.

Onto the gpu under-clocking I spoke of earlier, I see now that you can change the minimum frequency of the IGP but while out today I noticed it will reset to 578Mhz upon wake from sleep and get stuck there until reboot. The minimum does set correctly and can be reduced(checked with 3Dmark) but this bug screws it up on wake., the minimum frequency can be set from 200Mhz to 578Mhz the maximum can be set from 200Mhz to 778Mhz.(obviously the previous will screw you if you set it lower than 578Mhz and then let the tab sleep) The frequency table for the IGP should be 200, 222, 244, 267, 289, 311, 333, 356, 378, 400, 422, 444, 467, 489, 511, 533, 556, 578, 600, 622, 644, 667, 689, 711, 733, 756, 778.(obvious pattern) In Synapse I saw it definitely resets upon sleep.(since it prompts to apply after sleep and clearly shows the min as being reset to 578Mhz) So reducing the minimum frequency is out of the question since it will reset anyway but the max can be reduced. Not really sure if this is a bug though, might be that Intel deemed that this increases wake time but still for it to get stuck at 578Mhz sucks.

also if you have any idea where the settings in the AudioConfigurableDomains.xml are passed on to the system can you pm me I would like to edit them and hear the difference immediately instead of have to reboot every single time -_-, If the kernel restricts this that sucks but is ok since we can't edit it anyway :(.

why you turned encryption on? is your tablet rooted? if yes, I would not turned on encryption. Keep in mind that encryption is one way, you can't turned it off, you have to re-install official firmware from scratch....

I encrypt all my Android devices, using a strong pass-phrase, in case they get lost/stolen.

[Android Q&A, Help & Troubleshooting] sirxdroid:
My son plays NFS and Asphalt 8 and a full charge doesn't last more than 2 hours. The battery on the Nexus 7 playing the same games lasts at least 2x as long if not more.

I applied the latest OS update and now I'm having WiFi problems. I have the WiFi set to turn off when the screen is off, to conserve battery and also because I don't want to hear any notifications. WiFi is supposed to connect when the screen turns on but more often than not WiFi doesn't work at all, it seems the driver or something else crashed as not even the on/off WiFi toggle or airplane mode works anymore. Only a reboot saves it.

The tablet also randomly reboots when it's charging.

Overall the tablet is very cheap and you get what you pay for, it's a disappointing device, I should have gotten another Nexus 7 which I have been very happy with, but I wanted a slightly bigger screen.
[Android Q&A, Help & Troubleshooting] KainXSS:
thats about what I get out of it 5-6 hours of browsing or reading without underclocking :( and thats if nothings running doing binary translations with houdini since this is an intel device like mangawatcher which will drain the battery and heat up the tablet since its not make for x86.(had to stop using it) Haven't tried many market games on it but do use emulators and get about 3:30 hours out of it on a full charge myself, battery life could be better yea but I also notice the governors on this tablet also need to be optimized also. Really hoping they fix this stuff before a lollipop release or do a beta like they are doing for the Z3745 Yoga Tablet 2's.

I made a backup (better say: several!!).

It stores the following:

boot.img

cache.ext4

dat.ext4

nandroid.md5

recovery.img

recovery.txt

system.ext4

So far so good, or bad? After hours of reading, searching, trying, testing.....I am tired. The problem is: How to make this 'backup' flashable? How will I be able to 'really' extract the system.ext4? ext4_unpacker is coming up with some errors, like can't read or open files...

I have tried many many times..... At least I took the boot.img, recovery.img from the S8-50L and placed the system.img from S8-50F and flashed it using Phone Flash Tool, doing a custom flash...

Ok, It worked, but of course S8-50F came out....So, please please, please, how will I be able, or better say,

what do I have to do, to extract the system.ext4 without error messages?

How can I convert the system file into an img??

As you can see....I am really P.O.

Thanks for all information....
[Android Q&A, Help & Troubleshooting] jazzespresso:
if you are trying to extract nandroid backup file system.ext4, I would recommend you to search "CWM nandbackup files extractor" here in XDA forum or google it. If you could not find, download tool.zip I am attaching here.

unzip tool.zip and put your system.ext4 in the same folder.

open command prompt where cat.exe (tool.zip)

and type:

cat system.ext4 > system.tar

and still on command prompt, type this;

tartool.exe -x system.tar system

this would extract your system.ext4 and put it under system folder. Anyway, this is just alternate way to extract system.ext4, I am not sure if this will work for you.

Now, if you want to dump system.img from your tablet, there's couple of ways to do that, you may check http://xdaforums.com/showthread.php?t=2450045,

I was able to get my battery up to about 8 hours with no underclocking. First I use trickster mod and use the interactive governor and under governor control I change the go_highspeed load to 80. Next I decided to use google launcher. I think I get most of my battery savings from google launcher. I always thought it would drain the battery more, but on this device it does great. I don't show any slow down in daily use at all. I use the tablet quite a bit through out the day with games, facebook, iheart and videos. Love this tablet.......hope it gets some support soon.

---------- Post added at 06:40 AM ---------- Previous post was at 06:12 AM ----------

I have read dozens of posts on the brightness issue. Strange enough, I have no issues at all. By brightness stays perfect, I have no flickering or dimming when watching videos. I have done all the updates and rooted. I keep my DPI at 330 and use trickster mod for a little better CPU control (interactive). Other than that, I have no issues. I get about 8 hours of battery and it doesn't lag at all, and I use it pretty heavy during the day. I also don't get any heating issues with charging or heavy use. I am assuming since everyone is having this issue, I must have a the only one that is "truly" broken....LOL.
[Android Q&A, Help & Troubleshooting] purpleurkle:
Yeah I think you definitely got lucky with your tablet, cause there's no way I could get 8 hours of game play. Of course it could be that we're playing different games caused I get better life pending on what game I'm playing or what apps in using that day. If I play clash of clans for example, my battery goes in no time. One of my first thoughts was to change the govern to interactive, but this tablet is already set to interactive by default so that was no help, but even with all its corks I still love this tablet. Battery problems are really my only real complaint, which the coolify app has helped a lot with the overheating so at least there that lol

(I had to mangle the link so I could post this... it's clickable in the original post.)

Has anyone been able to figure out how to get that case in the US? I've looked all over, but it only seems to be available from alzashop, which only ships to Europe, and Lenovo's various European sites, which also don't ship to the US.

I tried bugging LenovoUS about it on Twitter, but they were completely useless -- the one time they replied, it was to send me a link to a case for the A8-50, which is a different size and shape.

All the similar cases on Amazon and eBay (by FYY and Fitian) look bad -- they both have frames that look like they cover the MicroSD slot, and one has a magnet that puts the tablet to sleep when the cover is folded back. Am I wrong about those frames? I have no interest in the ones that fold up into a tiny triangle.

Failing that, this tablet has very similar overall dimensions to the Samsung Galaxy Tab 4 8.0 and the Samsung Galaxy Tab 3 8-inch, but the corners are pointier. Are there any cases for those that this tablet could fit in while leaving the various buttons and slots accessible?

Is Alzashop still the best option for the case? It comes to around £16 with shipping, which seems quite a lot for a case and is more than I had to pay for decent cases for my Sero 7 Pro and Lenovo A8-50.

Are these screen protectors good enough http://www.amazon.co.uk/Savvies-Ult...9037&sr=1-2-fkmr0&keywords=illumishield+s8-50 or do I need to spend a lot more on something like this http://www.amazon.co.uk/Celicious-A...9037&sr=1-3-fkmr0&keywords=illumishield+s8-50 ?

I bought a tempered glass protector for my A8-50 after reading how superior they supposedly are but I found a con with them is that they're quite rigid, so it's not easy to bend them when applying to squeeze any air out and I ended up with some large air pockets. I managed to squeeze them off the display area and onto the bezel but they still look nasty and I was rather disappointed after spending ages finding a suitable tempered glass protector and paying the premium for it.
