This is I think someway related to WiFi settings. If you are on stock ROM and you go to advanced WiFi settings and check the option for keeping the WiFi on during sleep then hanging becomes frequent. Otherwise its ok. It does hang sometimes during sleep/charging. But rare now.

I have not experienced much hanging with custom ROM. I think somebody mentioned that WiFi hardware not compatible with sleep or something like that. But I always keep that option off now.

auto shutdown st8

thnx for the reply fuser & handy, like i wrote in my previous post i have not done anything except rooting, memmory swap and ui change no other changes on the stock rom, so am on the stock jb wich came with it.

i have not installd much of the apps or softwares just some games and nothing else... and i am seeing a error message whenevr i am restarting it wich is 'unfortunately the android media has stoppd working' comes for once or twice i press the only option ok and then everything becomes normal... and i dont know much about reading the log and all but i will try it as u said by logcat.

handy

my wifi option was set to only when plugged in all the time...
[Android General] fuser-invent:
You should definitely set wifi advanced option to "never" it's a bug/glitch on these types of tablets. For the android media stopped thing, try wiping dalvik and cache from TWRP recovery.
[Android General] masood939:
Fuser could you plz provide google earth app from the stock ROM coz it's not available in play store.Thanks.
[Android General] nitingoel2:
ok wifi option set to never... fuser can u please explain to me how to wipe dalvik and cache by twrp?
[Android General] sakshamdiwan:
The battery percentage works on my st8 but it shows battery at fixed intervals like when the battery is about to reach 85% it shows 85% and freezes there till the battery reaches 71%. It shows battery percentage at only certain levels.

wipe dalvik cache

i did not found the wipe dalvik cache option in recovery mode instead there was wipe cache factory/data reset, wipe cache partition and wipe media partition.. in which i selected and wiped the 2nd one wipe cache partition.. everything seems ok till now..
[Android General] fuser-invent:
@ handy5876 - Not having the Wifi set to "never" can indeed cause many problems. I was the one that mentioned this earlier in the thread and gave some more details. Its just better to have it set to "never," you will have way less headaches.

@ masood939 - Can someone else please upload and link to google earth for masood939? Thanks.

@ nitingoel2 - Ozadroid posted the TWRP recovery, there is a link to it in the original post of this thread, you are trying to use the stock recovery which doesn't have that option. Boot into TWRP instead of the stock recovery. Select "Wipe -> Cache -> Swipe to Wipe -> Go Back -> Dalvik Cache -> Swipe to Wipe -> Reboot."

@ sakshamdiwan - Is everyone experiencing the battery percentage mod only showing the stock percentages or do other people get all the percentages? Did you change dpi settings in the build.prop?

process.media issue

Hi Fuser, I have tried your suggestion of wiping the dalvic cache, but the issue still persists. Also, have tried many other suggestion from googling like clearing data + cache of Media storage etc..... No luck. It is annoying once in a while. I see that process.media takes a lot of memory and battery

Others getting similar issues...?
[Android General] fuser-invent:
Sometimes this can happen with a bad or partial flash. On the Ainol Fire and Hero the best way to flash a ROM is "clear dalvik/cache -> flash ROM -> clear dalvik/cache -> Flash ROM -> clear dalvik/cache -> Reboot." If the problem still happens you can do a factory reset from the stop recovery, then put TWRP back on the card and then flash the ROM via the above method. Just an idea, you might have another underlying problem but I have encountered this problem multiple times and fixed it with the above method.
[Android General] Ozadroid:
Broken apps is mainly due to bad flash as fuser said. To avoid this make sure you flash a new Rom after wiping each and every partition(cache, Dalvik, factory rest, system). If u do this you will never get broken apps n weird problems. Atleast I haven't encountered these problems with flashing.

That problem is known as "Sleep of Death".. Issue might be with some corrupt files or kernel.

frequent wifi drops and poor connection

Is anyone else experiencing frequent Timeouts while using Google Play Store and other Apps requiring internet connection like FB, Youtube etc?

I have atleast 3 wifi bars Very Good or Good status but still when I use Play Store it Timeouts at almost every second click. I tried wiping cache, dalvik cache and Apps data, cache but no help.

I have Karbonn A9+ phone as well which works well and never drops from same distance.

Any solutions?

Wifi is not working on my ST 8, I have to restart to get it working using custom ROM 1.2, it was happening in custom 1.1 as well. It is happening frequently. Help me

I am not having battery percentage problem.
[Android General] fuser-invent:
Its probably your router settings then or a bad ROM flash and it needs to be re-flashed. It could also potentially be a bad solder on the wifi antenna but that is more rare, but it does happen. Trouble shooting would be:

1. Check router settings. Try a different channel, make sure the network is broadcasting, see if it fixes the problem.

2. Try another wifi network. At a friends house, work, family, where ever. If wifi is okay there then its your router. If it's not then its your device.

3. If it's your device, re-flash the ROM with wipes.

4. If it still doesn't work, explore hardware issues. Open the tablet, check soldering points, make sure antenna looks right.

I have Successfully Flashed ST8 Custom Rom v1.2 - Working for me

Hi fuser-invent

I have Karbonn Smart Tab 8 - ST8

I have flashed ur Karbonn Custom ST8 - v1.2 by fuser-invent :good: successfully that too without wiping any of my existing data.

Yes few apps revert back to old version but i had them backed up via titanium backup pro. So used that to restore the latest version and same applies to google earth and many others that i need from stock room :)

And ROM is working properly. I will let u know any bugs if i find any. So far so good. I can feel the difference in it. Thanks a million for ur hard work and dedication buddy.

And Thanks to ozadroid for TWRP. :good:

And thanks to Ankit too. :good:

Hi fuser,

Only thing i notice until now is i cannot clear multiple notification from notification tray in this new tablet ui. I need to manually clear them one by one. The all clear button doesn't seams to work.

Any idea about this?

It used to work with Phone or Phablet UI
[Android General] Saurabh_Joshi:
I have no issues with wifi. I would say it is working way better then before. I am getting the full speed. BTW i am using channel 7 on my wifi router.

---------- Post added at 04:08 PM ---------- Previous post was at 04:03 PM ----------

I got your point. But one question how to download huge/big files like torrent on to this device then ? As as soon as tablet sleeps it will turn the wifi off. Or i need to keep the display setting to never sleep or is there some other way?
[Android General] sudersanmurthy:
+1 i would also like to download torrent files so how to enable wifi on always ,i tried changing wifi settings and also set wifi sleep policy to false but everytime the screen goes off wifi goes off :confused:

Karbonn ST8 Rooting & Rom flashing

Hi fuser-invent ,ankitdaruler ,

First of all I congradulates and thanks both of you and others for developing ST8 & ST10

I have Karbonn Smart Tab 8 Running successfully since Jan 2013 . I am following this thread from starting.

I have rooted, Memory swapped ,installed TWRP and lag free tweak and installed Titanium backup pro.

I have flashed my tab with Karbonn Stock+Rom-1.2 first & uninstalled it and then after one day installed Custom Rom ST8 - v1.2 by fuser-invent successfully that too without wiping any of my existing data.

1) But in custom rom 1.2 some times wifi is not working ,google play store showing connection timed out error , Game loft games like MC4 working not fixed.

2) How to remove karbonn logo on desktop screen in custom rom 1.2. It is not looking good.

3) How to instal stock app launcher , i have uninstalled the Nova launcher from custom rom 1.2 tablet is not working. Now I have reflashed with Custom rom 1.01.

4) I am facing Screen of death problem since 1 month. How to reolve it.

@fuser,

Very good.

Would you be kind to share the touch screen settings/tweaks?
[Android General] mushipkw:
Try the app Screen Standby on Play Store.
[Android General] yo yo:
Yes same for me

I flashed your custom ROM. And i too experiencing the same issue with battery % indicator.
[Android General] Saurabh_Joshi:
OK I will try. And get back to you.

---------- Post added at 03:12 AM ---------- Previous post was at 02:59 AM ----------

I am already doing that. I hope fuser can put some more light on this matter. :)

For all those getting tab into deep sleep mode, interrupting wi-fi.. this app can come in handy :) It restricts tab goin into deep sleep :) But downloadin large data files can also affect ya tab battery life.. so be careful :):)

Here's the touchscreen stuff for the build.prop:

# Touch screen calibration and scroll responsiveness
debug.performance.tuning=1
windowsmgr.max_events_per_sec=200
view.touch_slop=2
view.scroll_friction=1.5
view.minimum_fling_velocity=25
ro.max.fling_velocity=12000
ro.min.fling_velocity=8000
ro.min_pointer_dur=8
touch.size.calibration=geometric
touch.size.scale=100
#touch.size.bias=70
touch.pressure.calibration=amplitude
touch.pressure.scale=0.3

The Kernel and Dalvik tweaks also help with this because they speed up the systems response in general.

For people with Gameloft problems, if you didn't download the official paid app from the play store market its not going to work. If you did download it from the play store then try and uninstall and re-install it, as well as clearing all the data, because its treated differently. The Gameloft fix has been confirmed to be working with official Gameloft game downloads.

So changing "ro.platform.has.sleeppolicy=true" to "ro.platform.has.sleeppolicy=false" in the build.prop doesn't work for anyone with the wifi thing? If someone else who doesn't really care about it can just change it, reboot, test it and then change it back it would be helpful. I need to know if its just a select few people or everyone. Also does the problem exist on the Stock+ ROM as well or just the Custom one? It could be an issue with the android.policy.jar (at least I think that's where the settings are) that I can make a optional flashable zip for.

Is the battery percentage interval problem in custom ST8, ST10 or both. It could be possible the .xml files aren't correct.

I'm sorry but I won't change launchers, bootanimations or wallpapers. If you want the stock launcher you pull it from the stock firmware and install it. If you want a different bootanimiation you find one and place it in the system/media folder. If you want a different wallpaper you find one, press and hold on the home screen and then apply it. Also if you uninstall Nova launcher without having another launcher installed, of course the tablet won't work, because you won't have a launcher.

Sorry if I missed anyone's questions, I don't have a lot of time this week. I'll check back in when I get a chance.
[Android General] sudersanmurthy:
@fuser-invent as far as I know stock ROM 1.1 has this WiFi problem and in stock ROM 1.2 by setting WiFi to Never WiFi does not gets off when screen gets off, whereas in custom ROM I think I faced this WiFi issue in all custom version ,no matter you set it to false or change settings in advanced WiFi setting ,WiFi goes off when screen goes off

About the battery it drains 100 85 71 etc not by 1 percentage
[Android General] fuser-invent:
Sorry, are you saying Stock PLUS 1.1 has problem, Stock PLUS 1.2 doesn't and all custom ROM versions do?
[Android General] Saurabh_Joshi:
Fuser I don't face any WiFi issues. I need to test the sleep issue more. I will check and get back to u on the battery bug. Btw I have installed your custom latest ROM for ST8
[Android General] sudersanmurthy:
yes thats why now i reflashed to stock v 1.2 where wifi stays on when screen gets off ,becuase i needed to download a 8gb torrent file so if you could fix it in your latest custom version would be very grateful

@fuser-invent need some info

@fuser-invent I have downloaded crystal clear SD switch and SD revert is it the same as the vold and vold revert files only that it is an update.zip file and will it work with my own factory stock ROM of ST10

Forgive my stupid questions but I am a total newbe to these things in android and don't want to brick my phone and want to be 100% sure of what I have

Can you tell me the use of the other file that was in your media fire account-crystal clear re enable data 3g

Ainol factory reset

Ainol format internal memory

Also how to extract and flash stock recovery in the tablet such that the customer care does not know anything when I go to service center

I have read the entire forum in the last 2 days and I want to ask you that should I keep a backup of the recovery and boot.IMG file as a precsution
[Android General] Ozadroid:
Use 'Android partition manager' from play store to dump boot recovery n system partitions.

And I would suggest don't touch boot partition by any means coz it may hard brick your device if not carefull .

got custom 1.2

Just now installed Custom ROM 1.2 by fuser ( :angel: thanks a ton buddy) without wiping or factory reset and all my apps are restored after SD swap flash.

The only thing till now seems a problem is:

- Battery %age isn't accurate, seems it goes like 100, 85, 71 and time gap is there

- Settings and setting->Apps freezes tablet for a min

- Connection Timeout with Google Play Store is still there, even after having 3 wifi bars with a 2 mbps connection

Is anyone here working on porting the Ubuntu touch on karbonn St and 10
[Android General] fuser-invent:
@ anandisrocking007 - Yes the SD swapper patches are just flashable vold.fstab replacements, they will work with any stock based ROM. Just make sure to flash them in TWRP as stated. crystal clear re enable data 3g changes the build.prop settings back to stock so that you can use 3G dongles but your tablet will never enter deep sleep, that's why I shut them off by default. The internal memory format zip formats you internal memory and the factory reset zip does the same thing as the stock recoveries factory reset. You should keep a backup of your stock ROM if you haven't changed it yet. There is no official firmware release to re-flash if you have a problem and there is no official stock recovery release.

@ vpandey - Please let me know which custom ROM you flashed, ST8 or ST10. I really can't keep up with which tablets people have and I still don't know if this battery percentage problem is in ST8, ST10 or both. As soon as I know for sure I can attempt to fix it. The segmentation fault in the setting -> apps is a known issue, especially with rooted devices, use Titanium Backup or ROM Toolbox instead. There is a bunch of wifi info a few pages back.

@ souryakharb - You keep asking this, I guarantee no one is working on a Ubuntu port or even if they are it probably won't work since no one has gotten it to work on any Cortex A9 tablet. Its also in super-beta so most of the basic functions of the tablet wouldn't work even if there was a port.
[Android General] vpandey:
I have st8 ..... setting -> app freez was there prior to flash as well.... also wifi tweeks i feel you already incorporated in ROM .... isnt ?
[Android General] fuser-invent:
Yes the settings -> apps thing is just a common android annoyance and all the wifi tweaks are incorporated into the Custom ROM but not the Stock+ ROM.

Thanks for the report that it is the ST8 with the battery percentage mod problem. Now, does anyone with an ST10 have that same problem or should I just get started on looking into the ST8?

I'll also start working on the next update for you guys next week. I've been ultra busy at work and my time has been thin. Everyone should go bug Karbonn to release an official stock firmware if you have free time or link them to this thread and my user profile and tell them to send me anything they have.
[Android General] sudersanmurthy:
I have st10 and I have the same problem
[Android General] fuser-invent:
Okay, if it's happening on only some ST8 and ST10's, did you all try to do a factory rest and double flash the ROM or not? Because if it works on some tablets and not other, it seems to me that it would be a bad flash and not just that one of the ROM's was missing something.
[Android General] sudersanmurthy:
Yes I always wipe before flashing , and almost flashed custom ROM 4 times but I have the she battery issue ,has anyone reported the the battery is running fine
[Android General] fuser-invent:
Yes, that's what is confusing me, multiple people with ST10's have reported it running fine, but no one with an ST8 yet. Well, I guess what I'm going to do is just decompile the systemUI.apk and do it all over again from scratch, just in case I missed something, but this really makes no sense to me. I've done this battery mod dozens of times now on multiple devices and never had this problem.
[Android General] sudersanmurthy:
That's really weird I thought the battery problem was universal ,since I din read any post that the battery is working fine and any news about WiFi issue , I am using stock ROM 1.2 just becoz of WiFi even though custom ROM is much better

It would be better if someone makes a different thread for st10 and St 8 to avoid confusion

Hi guys i dont know why karbonn has disabled the contact app just because we cant phone does not mean that we dont need a place to save contacts i have checked googleplay and came up with a lot of apps to store contacts but it contain a lot of useless features for calling and sms the good one takes a lot of space i just came by this app called gimme contact about 4.7 Kb what it does is to let you use the default android contacts app. no extra stuffs i admit the the icon is bad but it is of no concert for people using custom launcher which can change icon.If someone can edit this apk icon and post it with the google contact icon it would be great.

Factory reset and Memory swap Confusion

So if i flash my tablet with your stock plus or custom ROM what will happen if i factory rest it in my settings i had read in somewhere that the factory reset is totally in another partition if i make a backup will the factory rest be backed up if not how to make one and also one more thing up i remove bloatware or add extra apps in the system apps folder and do a factory reset will those new apps remain or will it be deleted.

so if i use the factory reset.zip it will only do a factory reset on any of the ROM that you give and also i cant you the memory swap zip with stock recovery:eek:
