IMPORTANT - THERE IS A SYSTEM APP CALLED FWTOOL. DO NOT USE IT TO FLASH FIRMWARE OR YOU MAY END UP BRICKING YOUR TOUCHSCREEN. ALSO DO NOT FLASH ANY VERSION OF lk.rom OR YOU WILL BRICK YOUR TABLET.
To install clockworkmod
Download EM73-8K-recovery-signed.zip below. Rename it to update.zip and copy it to the root of your SD card.
With your tablet already turned off, press and hold down the Back button and then press the power on button while still holding down the Back button. This will open stock Recovery.
Use the buttons on the top of your tablet to navigate your way through recovery and to select menu items (menu = down, back = returns to previous menu, home = selects option).
Navigate to apply update.zip & follow the instructions. Reboot.
To use clockworkmod just press and hold down the Back button while powering up your tablet. Navigate the menu via the buttons (menu = down, back = returns to previous menu, home = selects option).
To make a Nandroid (clockworkmod) backup boot into clockworkmod recovery & navigate down to Backup then follow the instructions.
To root your tablet ** please see comment at end of post before continuing past this point
+++Make a full Nandroid (clockworkmod) backup before attempting this+++
Download & unzip Superoneclick from http://forum.xda-developers.com/showthread.php?t=803682 - NB you may need to turn off any antivirus program on your PC to allow downloading & use of Superoneclick.
Download & unzip the relevant Drivers folder (32 or 64 bit) from link below then connect your (powered on) tablet to your PC & point Device Manager to your unzipped drivers folder when it is looking for drivers.
Make sure USB debugging is allowed on your tablet (Settings -> Development -> USB debugging)
Right-click on Superoneclick.exe, select Run as administrator then click on the Root button. It will take 2 or 3 minutes for your device to be rooted.
This procedure has worked for my own tablet but I accept no responsibility if you end up bricking your device!

To stop battery drain & prevent screen from waking every few minutes - **only for original Kogan ROM**
(with thanks to hallokitty for this fix)
This happens because the tablet keeps looking for the 3G signal it cannot ever receive. To fix this, go to System/app using Root Explorer from the Market, delete (or rename) phone.apk and TelephonyProvider.apk. You will immediately start getting errors but just use the reset button at the back of the tablet and when you reboot the problem has been solved. If you ever want to restore these apk's (e.g. if you want to use a 3G modem) just flash the phone+telephony zip file below using clockwork mod.
Clockworkmod rescue backups
I've done a factory reset & wipe of my tablet & made clockworkmod backups which I've linked to below. Make sure you do a full Nandroid backup before applying any of these. Unzip the file & place it in the appropriate Nandroid folder on your SD card (/clockworkmod/backup/), don't try to flash the zip file using CWM! These are a slightly slimmed down versions of the ROMs - for the Kogan ROM I've removed phone.apk, telephony.apk, Email, Facebook, Twitter, FW tool (dangerous to have), ES Explorer, Live Wallpapers and ES task manager. I've upgraded Spare Parts to Spare Parts + and added Astro File Manager as a user app. I had removed most of these things from my ROM before I was ever asked to make this backup so if you want to reinstall them you can get them from the Market or flash the relevant apk's into the system/app folder using CWM. The ROM is still rooted. You will need to do a factory reset & wipe the Data partition & Dalvik cache with CWM prior to doing this. If you want to use a 3G modem you will need to flash the "phone + telephony.zip" file listed below with clockworkmod.
Kogan firmware clockworkmod rescue backup: http://www.mediafire.com/?izfedrz97iowi34
**If you're really lazy you can combine rooting the tablet, removing unnecessary system apps & applying the screen wake fix by installing clockworkmod then restoring the rescue backup (NB make sure you make your own Nandroid backup first!!!).
CM7 runs extremely well on the Kogan except for HDMI out & Camera which don't work yet. You will also need to install Gmail & Youtube apps from the Market if you want them. Make sure you do a full CWM/Nandroid backup before trying this as I had problems with an unresponsive touchscreen after flashing the most recent CM7 ROM. For more info head here.
Tips & Tricks
MoboPlayer is a good video player, particularly for its ability to let you change the volume & screen brightness by swiping up & down directly on the video you are watching. The volume softkeys on the Kogan are not visible if any app is in fullscreen mode.
Titanium Backup may not show all installed apps or any system apps. To fix this go to Titanium Backup's Preferences and tick "Force use system Busybox" and "Force use system SQlite".

Lucky you - they're really dragging their heels with mine. Can you upload the kernel & we can see about getting clockworkmod for it?
How do you rate it as a tablet? Is the keyboard OK? - some people have said it's a bit carp.
I got mine today. It's going back as soon as I can get Kogan to respond.
Turns itself on & off at random, poor quality screen, sound, responsiveness.
Touchscreen activates itself without being touched.
What was I thinking? I guess you get what you pay for.
Now if only I could get them to reply to an email.......
Ok i have to agree you get what you pay for so i had low exectations. Its no flyer,tab,transformer but then it was a 1/4 of the cost. Yes the screen has issues (partly i think due to the screen protecter and battery life is poor though ive had this on for about 2 hrs now and its about 2/3rds down.
All in all im happy though going to live with it for a bit and i reserve the right to change my mind.
Wil right more when i have aproper keyboard
yeh i get the same problem with the screen comming on and off randomly.. i wish i could stop that =P (would save the 3 hour battery life i have to 4 hours!)
you get what you pay for =P but i thought the screen was quite good considering.
did you try the recovery yet?
how nice would it be to port oxygen to the kogan haha

The screen keeps coming on as the OS is looking for a 3G signal all the time. If you switch it to airplane mode it should stop happening. Or use http://www.appbrain.com/app/airplane-mode-wi-fi-tool/net.geekherd.airplanemode . Or you could even try adjusting the settings to use 2G only.
I can't adjust to 2g only on mine - it's greyed out.
Yes, I've put it back to factory setting a few times, but it's no better.
The switching on/off isn't the main problem (though it has used 30% of the batter life in 8 hours during the night).
The main issue is the touchscreen simply activating itself. If i go into a menu of any kind, it sometimes selects something for me. It happens too often to just ignore it.
Sounds like a faulty screen :-( - let us know how you get on returning it! If mine turns out to be rubbish when it arrives my Plan B is this one http://mp4nation.net/catalog/index.php?main_page=product_info&cPath=68&products_id=496
well im having the random on issues (thanks for the airplane mode idea ill give it a tray) but the screen activations are not a problem.
@dwl99 that mp4nation link is the same as the kogan (a rebranded em73) so its likely to have the same niggles i think

A lot of these tablets are very similar (Herotab C8, Dropad A8) but there seem to be some important differences in the components used. I've been lurking in some Heropad C8 forums and nobody seems to have reported touchscreen problems.
This one look exactl;y the same , button layout etc etc however i know what you saying as even within the same model different components can be swapped in as costs change between runs

An app that sticks it in Airplane Mode when you put it into sleep mode is a good work around for now, try "Auto Airplane Mode" (I can't link because I haven't posted enough, it seems...
Hasn't randomly turned on since I installed this. Ahh, forget that, it seems to be doing it again, it just took a lot longer...
In general, this thing is a bit cheap and nasty, but I guess that's what I expected. The button placement is seriously weird, and the touchscreen and accelerometer are just inaccurate and jittery (try playing a game that uses the accelerometer! good luck!)
I feel like it could benefit a lot from a nice ROM though, to fix a few issues (where the hell is the accounts & sync menu?)

Been trying to find how to set these before
i found it once earlier on but i cant find it again!!!
it was not where i expected and i think i had to do a round about method to find it.
i have a feeling it had something to do when i was trying to sync email contact with a email app but i forgot which one lol..

just FYI on the kogans you can activate aeroplane mode in settings then using the power controls widget on your home screen turn on wifi
it will keep the aeroplane mode on but wifi on as well atleast it worked on mine you dont need an app for it.
i actually wonder if the screen wake has something to do with background sync should try turn it off for a night and see.
Okay, so after being plugged in and fully charged, I unplugged it and left to drain overnight to see what would happen.
I had "Auto Airplane Mode" on, but as you'll understand, it helped, but not enough.
Even in Airplane Mode, the tablet would wake itself up, then "Auto Airplane Mode" would see the screen is on, and turn the wifi back on, then back off when the screen faded.
But, I'm thinking this might be because it has Sync enabled. I'm going to try it again with sync disabled.
The battery graph was a joke - it started smoothly going down at a reasonable pace, then -no lie- it spiked down.. then UP, then down, then up, throughout the night. It was at about 75% when I turned it back on after say, 8 hours. Then it dropped to 72%, then I plugged it in, and it immediately reported 98%. The biggest drain by a long way is "Mobile Standby".
However, for the most part, bar the bad accelerometer, terrible button placement, and slightly sharp edges, the hardware itself is not terrible for the money - 512MB RAM and 1GHz processor; I don't mind 800x480 at 7", it looks passable, although it's bad in sunlight. (Of course the viewing angles are bad, but for the cost, that's expected/OK).
But damn the software needs tweaking because it just has problems.

Hi all since installing auto airplane I don't think im seeing wakes issues. I left the kogan overnight at about 50% battery and this morning it was at 35%. Ill test again tonight just to be sure as you seem to have the same build and kernel .
EDIT:
Ok i do still have it

Though I have to agree the roms a joke accourding to quick system info 77% of my power useage has been down to mobile standby HUH.
Edit one thought is the 3g component in there for the 3g USB comparability and if so that was a new feature so could there be a rom that exists without it. I have added a topic in this forum asking if its possible to strip the 3g component out.

Huh, no, it still seems to turn the screen on now and then even with sync off and in airplane mode. This thing needs a custom ROM as soon as possible. I imagine after a while people will start to sell them cheap because of problems that could mostly be fixed with better software, so I think it could be a pretty popular tablet for people willing to customise it..
I had been doing a great deal of tinkering trying to get my phone's battery life back in the last few days, and I made good progress, but I severely jacked up something related to the microphone/speaker/video recording.
PROBLEM:
The problem, as far as I can tell, is that every app that tries to access the microphone can't do it--this shows up when I try to use Google voice input in various text fields with a little "Can't reach Google at the moment." Same with trying to do a search by voice in Google Now--brief brief flash of the microphone red, then back to gray, with "Can't reach Google at the moment". Additionally, my Touchless Input cannot be enabled--the box has automatically unchecked itself, and pressing it makes the button get a little gray, registering the action, but no checkmark will appear.
Additionally, other apps which would use the mic don't seem to have that functionality--Evernote, for example, would crash if I attempted to record an audio clip. This was before I performed a factory data reset last night--and the problem has persisted regardless.
There are two other, seemingly related, issues. First is the inability of the phone to capture videos. The camera opens fine, and I can take fine stills with it, but pushing the video recording button makes the red "record" flash for a moment before a "Not able to record media" message pops up, and the camera returns to the still photo mode.
Second is the inability to play videos. I have tried playing videos in as many formats as I could try, from within several players, including the stock "Photos", "Gallery", and "YouTube" apps. "Sorry, cannot play video" pops up, or the app simply crashes. Similar story for attempting to play music through the stock "Google Play Music" app. And it gets worse. I can't make or receive calls. Actually, let me revise that. I can't hear anything being said on the calls, over the speaker, or through headphones (though I've yet to try BlueTooth). The call appears to connect, but I can't hear anything from them, and they can't hear anything from me.
So--that's the basic summary of the problem--threefold.
1. No audio input through mic
2. No audio output through speakers--my phone doesn't ring when I get a call, although it will vibrate and the options to take the call appear as they normally would.
3. No audio/video playback whatsoever for other media.
I'm running Android 4.4 on a Droid Mini, unrooted, and I just completed a factory reset last night.
ANALYSIS:
Here's the wrinkle. I know this isn't a hardware problem, because I have found a surefire fix that makes all of this work properly if I absolutely need it, it just sucks. Rebooting into safe mode is what does it. Playback resumes as it did before I had the problem. I can play videos, pump music, and Touchless Input works flawlessly--although interestingly, it has me re-enter the catchphrase three times every time I get into safemode, like setting up from scratch.
My consternation comes from the fact that, to my very limited knowledge, all that safe mode is doing keeping any user-added apps from running. Which is all well and good, but I just did a factory reset. Literally when I boot the phone no user installed apps are running, and yet there's a definite difference when I boot into safe mode, cuz everything works there.
So, safe mode must do something more than just disable user-installed apps--and I need to know what that is if I'm going to fix this thing. I have added 4 apps since then-- App Ops, GSAM Battery Monitor, BetterBatteryStats, and Button Savior (Non-root), all of which I know from experience to be very "well-behaved" apps.
Anyone know what safe mode is doing besides disabling user apps? Along those lines, does it revert updated stock apps to their factory state? I ask because very, very briefly, while my phone was slowly trying to upgrade the 40-odd pieces of Bloatware from the Play Store, the microphone was working. Which makes me think that the culprit is one of the system apps in it's updated form. If safe mode runs these apps as they originally appeared on the phone, that might explain it. It would also hopefully let me painstakingly disable these apps, one by one, to find the culprit and disable it.
I say culprit because of something I stumbled across trying to research this--weirdly enough, in a message from the devs of Shazam. devs of Shazam They say that the issue has shown up on 4.4 and the cause appears to be one app somehow monopolizing access to the microphone. I could see this breaking the video as well, and potentially the audio playback if, as I assume, Google uses the mic to help tweak the sound of the speakers.
Anyone know any more about any of the aspects of this? I will be posting back myself as I learn more.
What happens if you factory reset without restoring any apps? In other words, factory reset, choose not to restore your apps (or don't attach to a Google account on initial setup, and do it post-setup). In other words, do you have an app that is blocking this access?

Trying this now. Thanks for the suggestion!
Update: Tried this. Did another FDR, signed in to one of my Google accounts afterwards, but haven't updated a thing. The audio/voice/video/bugs seem gone; however, the ****ty battery drain I had before is back. I'm playing around with some settings to find out what can be done. I'm also going down the list and updating the system apps one by one.
Does anyone know a good testing process (ie, should I run the app? do I need to restart after install? run the app and close? etc) that will keep me from getting false negatives (ie thinking an app isn't causing the problem when it is)?
Update again: I'm working down in alphabetical order through the factory apps. However, after the most recent factory reset, it appears that my battery drain is back, and as long as the battery drain is there, the phone works normally. So, not looking good in terms of battery+functionality for me. Went through the 40ish apps that were on the phone stock--after the fresh reset, the phone is working, but the battery life is shot to **** all over again. Not sure what to make of all this, and now back to being frustrated with a 4 hour battery life from the phone that never sleeps. UGH
Update yet once more:
For kicks and giggles, tried unchecking the "Touchless Control" in settings, to see what effect that would have on my battery. But, reasoning that whatever wakelock was keeping my phone up all the time had to be persisting after it was needed, I guessed I needed to reboot to get rid of them. Booting up again, I'm back to battery life without audio/video/etc. Very confused here. Apparently it has nothing to do with the apps installed, period.
Facing the Same problem please someone tell me What should i do
Same problem! No audio call
Inviato dal mio Redmi Note 3 utilizzando Tapatalk
Please help me I have this same problem. No audio, cant play video, nd mic isn't working.
Has anybody ever seen anything like this? I'm experiencing a black box popping up maybe 20 seconds or so after booting that is unclosable with lorem ipsum text in it, here are some screenshots:
[xda won't let me post links yet so bear with me and fill in the rest of these urls]
imgur /LYCMosA.png

imgur.com /tde44HA.jpg
The box cannot be closed, and anything above it doesn't respond to touch input, but everything below it can still be used (like the shortcuts to chrome, contacts, etc. in the last screenshot). This box persists everywhere, including the lock screen.
Additionally, when I go to the lock screen the screen starts turning on and off rapidly, forcing me to reboot by holding the power and volume down key into maintenance mode.
I am able to start the phone in safe mode with no problems (safe mode disables all apps that aren't samsung or google), making me believe it's a third party app that is causing the issue and not something in android. But before I begin the awful task of uninstalling apps one by one to see which is the one that's causing the issue I figured I'd turn to reddit for help.
Additional info: I'm on verizon, the phone is rooted and I'm on 5.0.2
Flash with stock 5.1.1 ROM via odin.
Update: If you're reading this from the future it was cerberus, the security app. Really ****ing pissed because I uninstalled just about everything else because I didn't want to uninstall my security app until I had my phone back at my house (just tempting fate too much). Oh well, at least I've figured it out.
All,
First time poster, frequent visitor of XDA Forums. I've come across an odd issue that I don't know how to solve and I'm hoping some of you smarter than me folks can get me squared away.
I have a Galaxy S8+ from AT&T running Android 7.0 and Samsung Experience 8.1.
Problem:
I've recently noticed a delay or completely non-updating interface on my phone. It updates on occasion, but I can't determine what triggers an update. For example, I will pick up my phone from the desk and when I press the power button it shows the accurate time. When I unlock the device, the sense flip clock I use on the main home screen shows an earlier time (could be 30 minutes... could be a few hours). I don't believe it's just the Sense app because I noticed this issue where I checked a facebook messenger app that came and and when I closed the app, it still showed I had 1 notification. I went back in thinking I had another new message, but I didn't. So it was still hanging on to the notification. It happened a couple times with a text message as well. Most importantly, my calendar doesn't alert me prior to an appointment either, even though it's showing in my calendar and an alert is active. If I save an event, and exit, I can normally see the event appear on the on widget immediately as well... but that hasn't been happening. I have to press the widget to open it and confirm it is there (which it always is). Eventually it refreshes and shows up. But that delay is likely the reason why I'm not getting my alerts.
All of this did seem to happen after a recent update Samsung/AT&T pushed out but I don't know for sure. I tried clearing the cache from the boot menu but it doesn't seem there is wide success with that.
And perhaps I'm just not a good enough user, but everything isn't all backed up in the cloud so doing the factory reset to me is always a fairly large task as I have many things to manually transfer out and then back in. Not sure if there are great tools that help with this on a stock phone.
BUMP
try disabling battery optimization for those apps.
It seems that you have several bugs and if they all start happening after you have installed the latest update, then expect a patch coming soon.

I have actually done that. Found very limited success. I'm also finding very few results on this topic. Surely it's not just me though.
And I'm dreading the idea of a hard reset as I have many things on my phones, not all of which is sync'd to the cloud so it's a task to back things up appropriate. Specifically regarding "encrypted" apps like my password keeper app etc.
It would be great if there was a software application that allowed you to backup whatever is necessary to not lose data, then wipe the phone and instead of just simply restoring the full phone (which is likely to create the same problem one had before the hard reset), you could simply dump back in app data as needed. It would also help diagnose if the problem lies in a specific app's data.
High level overview of issues...
I have the Ring Doorbell app. I get notifications after "live". Could be 5 minutes, could be 1 hour... or possibly not at all. I have the app setup on my wife's iPhone and she gets them immediately. If I restart the phone, I will get notified right away (it's like it runs the app again and then I get the notification). Keep in mind, this is AFTER i disabled the battery optimization feature for the Ring app.
I also notice it occasionally with texting. I won't have any text notification in the notification panel, nor will my messaging icon have a little red circle indicating a message is there. But if I open the app, a specification conversation will have a red circle indicating a new text is unread.
All of this is leading me to believe the Samsung UI itself is not updating and therefore notifications that actually have arrived (from whatever app), are not displaying because of the UI and not because of their own delay.
Because of this concern I have turned off battery optimization for "System UI", "Themes", and "TouchWiz Home". I have not seen any change however.
[Solved]
I was able to determine by various other threads around the web (thought for sure I'd find it here, but I didn't) that the culprit might be the Google app. Supposedly it was fixed in some prior release, but it's not on my Galaxy S8+ w/ AT&T.
Once I disabled the Google app all the odd issues with notifications and clock interfaces and app icons not updating went away. The downside to disabling it is that I lose the Google Assistant functionality which stinks but otherwise there is no impact to using the phone. I re-enabled it at a later date and it worked fine for a few days and then started acting up again. Once I disabled it, the problems all disappeared. Clearly Google app is to blame.
Hello, for example, when I switch from a game to the browser for a few minutes, when I come back to the game it restarts completely, right now the only solution I found to this is to switch back to it regularly to keep it open, which is annoying and ridiculous. I tried dev option to allow 4 background apps, it didn't work, I did read about battery optimization but my phone is only on android 4.1.2 with no way to upgrade it so I don't have this option.
So, is there some app or modification I can do to avoid this ? If it's the only solution, it would even be fine if some autohotkey-like script would automatically switch back and forth to it as a hotfix.
turn off battery optimization
Unfortunately it's not present in android 4 unless I'm mistaken.
If anyone have the same issue here is a workaround I found: I stop absolutely everything, adblock, music player, onedrive (which I even force stop so it doesn't reopen itself half an hour later), even a tiny app that just forces the phone to stay in landscape mode, and I never switch off the screen and avoid to press the home key, this way I have exactly one current and one background app that stay open.
