Hello guys,

Just wanted to know if there's any thing specific to be done to flash the rom and gapps afterwards.

Also, can some one point out the gapps link for me please?
[Galaxy Tab 7.7 Android Development] racker:
Hey Daniel. after about a week with the ROM i noticed a few other things.

Probably related to HWA but the game deadspace and the drop box app won't open. They both try and sometimes get to the splash screen then I kicked out to the home screen or app drawer. I cleared dalvik and fixed permissions as well as reloaded each app from the play store.

Also (and this is very odd) I play Plague Inc quite a bit and this ROM plays it great except for the sounds. none of the touch/action sounds are being played (audible?) but the game music is playing fine. the touch sounds when i perform an action are not audible. Another game I play is clash of clans which plays all sounds just fine though...

Thanks!

Lol thanks.. Gotta check my eyes then...

thanks for the update Daniel :good:
[Galaxy Tab 7.7 Android Development] sas_sas:
Ths for the great efforts you made...

Just flashed. All looks fine.

Just İ did not find the way of installing of Google Maps..

Media server or storage is increadably draining battery...
[Galaxy Tab 7.7 Android Development] kevin613:
Thanks Daniel,

flashed build 4.6, and all went well. rom is silky smooth.

anyone noticed any tearing? any way to confirm if the VSync is off in this rom?

not a deal breaker, and this is definitely going to be my daily driver.
[Galaxy Tab 7.7 Android Development] robt2379:
Flashed this new build and so far finding things to be very nice. Bluetooth is much more stable and battery life is great.

No issues at all so far.

[Galaxy Tab 7.7 Android Development] earthman5678:
Hi Daniel. Installed your latest build 4.6. I found that the graphic is not smooth when scrolling. I just want to confirm that this is a known issue.

Thanks.
[Galaxy Tab 7.7 Android Development] daniel_hk:
Google Maps?! Obviously, you can get it from Play, right? :cyclops:

Media scanning will be done at boot. Depends on how much data is in your SD(internal and/or external). If they are quite full, the first time would take much longer to scan. Tab might respond laggy and consume power. After the first scan, it would not be noticible. That is the way new Android behave. You may disable it.

If it is right after the first boot, It might be the media scanning mentioned above.

Haven't touch graphic part for a few months. :cyclops:
[Galaxy Tab 7.7 Android Development] earthman5678:
I don't think it is the media scan. I came from your PAC ROM and somehow the screen when scrolling is not as smooth as PAC. The left side of the screen appear to be lagging when scrolling quickly in some application (e.g Dolphin)
[Galaxy Tab 7.7 Android Development] kevin613:
i believe what you're seeing is screen tearing, same as mine, the left side of the screen appeared to be lagging when scroll up and down.
[Galaxy Tab 7.7 Android Development] Lt.col.johncross:
I was just about to say this ROM was dragging - many diff apps we're dragging and I could not get passwords to save. Many other little quirks were getting to me also. After reading some replys on how smooth it was and a few quoting drags I decided to redownload the zips to my PC. I then used twrp to format the tab then installed the ROM the gapps and superuser back to back. Now it flies - very responsive -saving passwords- If the revolving screen glitch gets fixed WOW. For now i will just keep trying apps that dont glitch when rotated. Although sometimes even my status bar goes wiggly when rotated. Thanks again daniel and for others -sometimes when you think its not working it could just be a bad download or install.
[Galaxy Tab 7.7 Android Development] earthman5678:
So it is not just me. I wonder if the screen tearing issue is on Daniel to do list.
[Galaxy Tab 7.7 Android Development] Kholargol:
If I'm actually running on a Jelly Bean Rom, I just have to make a full wipe + format system before install, right ?
[Galaxy Tab 7.7 Android Development] rebski:
I followed the advice given by Lt.col.johncross here

This worked perfectly for me.

NICE ROM!! Coming off omni which was just causing too many problems. I have none with this ROM so far! Nice job!!
[Galaxy Tab 7.7 Android Development] earthman5678:
Installed 5.1 0516

Screen tearing is still there. Is this fix in your plan Daniel?

Again, great work Daniel. Appreciate it a lot.
[Galaxy Tab 7.7 Android Development] daniel_hk:
To be honest, I really don't know what you meant by tearing. Something about scrolling? but I try a lot of scrolling. Didn't observe any apparent abnormality.

May be a bit laggy right after boot. Background process are still running.

eg. account login, fstrim, media scan (which can be disabled in advance settings), etc

If you want to report something, you need to let me know what it is. Treat me like your grannie. :D

Take a video and explain as detail as possible. Test it before install/restore any app. And next time state which model you have...

I haven't changed OV/UV for a long long time. Just checked, still there. Clear your app data or try others.

Occasionally clean up or better still format your /data is a good habit. Fragments or lost data might grow as time passes.

To all,

I want to answer every question. But if it is already stated in posts, I rather let you find out yourself instead of repeating again and again...

Read the posts first, someone might have already spent time sharing his experience. Most of the time, you would get your answer. ;)

Good luck!
[Galaxy Tab 7.7 Android Development] rebski:
If you would like to give me instances of when this occurs I shall see if I can reproduce it on my Tab.

So far I have not noticed such artifacts but then I am not yet using that SlimKat on a regular basis so my usage is not exhaustive.
[Galaxy Tab 7.7 Android Development] kevin613:
Hi Daniel,

the artefact is similar to this video

http://www.youtube.com/watch?v=Y8xWHi1PwV8

i can't post mine as i couldn't get it to show clearly in videos i captured.

happens only while scrolling on P6800

tested on google newstand, and also noticeable when scrolling in Settings menu.

not sure how it can be fixed in Android, but on PC, enabling VSync will solve this (and also capping the fps to 60)
[Galaxy Tab 7.7 Android Development] biopsin:
tweaking the scheduler helps with the "tearing" at least it does on 4.2.2, try adjusting one at a time and see how it affects scrolling.. look at the performance/prosessor tab in settings and see how the mhz is jumping around every second, to much and expect crappy batterylife....

for ondemand scheduler:

echo 50000 > /sys/devices/system/cpu/cpufreq/ondemand/sampling_rate

echo 5 > /sys/devices/system/cpu/cpufreq/ondemand/down_differential

echo 2 > /sys/devices/system/cpu/cpufreq/ondemand/sampling_down_factor

echo 95 > /sys/devices/system/cpu/cpufreq/ondemand/freq_step

echo 35 > /sys/devices/system/cpu/cpufreq/ondemand/up_threshold

echo 20 > /sys/devices/system/cpu/cpufreq/busfreq_up_threshold

same with the white light suddenly flashing on left screen side..
[Galaxy Tab 7.7 Android Development] earthman5678:
OC/UV still there. My bad. The new ROM replaced the SU setting. I had to turn it on again to see it. My bad, my apology.

The screen tear thing, it is like what kevin613 has explained.

There is also the vertical white light in a line from top to bottom at the left side on the screen like biospin said.

Daniel, are you using 6810? I'm trying to guess why you don't see it. I'm guessing the common denominator is 6800.

---------- Post added at 03:23 PM ---------- Previous post was at 03:12 PM ----------

Thanks for the suggestion. I did noticed the improvement when I OC it to 1.6GHz.

I hope Daniel finds the problem. I didn't notice the problem when I was with Daniel final PAC ROM 4.2.2.
[Galaxy Tab 7.7 Android Development] rebski:
I have installed Google Play Newsstand, tested it along with Settings and web browser.

I can report no incidents of white flashing light or of tearing as demonstrated in that video. I agree that there is sometimes a little glitch on the left hand side when scrolling down the web browser (XScope) while in portrait mode but that is not at all evident in landscape mode.

My experience is that this is so slight - and specific to web browsing in in portrait more - as to be hardly worthy of comment. Indeed I doubt I would even have noticed it were it not for the issues others have reported.
[Galaxy Tab 7.7 Android Development] porfys:
What I have to do to see videos .avi?

I installed the best video players in the tablet and can not be reproduced. (mxplayer - moboplayer - bsplayer)

Thanks Daniel for the ROM....
[Galaxy Tab 7.7 Android Development] rebski:
I see what you mean, that was a shocker.

My video files are either Blu-ray ripped MKVs or YouTube downloaded MP4s. I tried various players including MX Player Pro, Dice Player, RockPlayer2, RealPlayer, Videolan VLC for Android Beta.

The only player that worked was MX Player Pro and even that required a reboot to stop it hanging in the initial attempt. The others either choked on the file or else played it in video only, no audio.

If anyone has suggestions as to what to do I am happy to try them out.

Edit

If Dice Player is given access to the file libffmpeg.so then it plays the MKVs but still chokes on the MP4s
[Galaxy Tab 7.7 Android Development] heyjoe66:
So firs of all, thanks to you, Daniel, for you hard work.

I want to share my experience of using this ROM (share experienced bugs actually):

- VSync problem is indeed here, I can see it when scrolling lists. Also can be clearly seen when pulling down quick settings dropdown above some windows with white background, the fade effect reveals than "tearing". Scrolling AppDrawer in Nova Launcher looks VSynced (but still jumpy), playing video with BsPlayer looks totally fine;

- GSM network doesn't start after boot and it happens REALLY OFTEN. Setting to "Prefer 2G" and restart does help, then I can set it to 3G, but after restart it'll die again. Attached some logs, maybe will help;

- WiFi 5GHz not in range after restart. Tinkering with WiFi settings, turning WiFi off/on does help;

- Settings > Security > Slider targets gives FC;

- Camera Exposure seems to be fixed on some high value, setting in to -2 in stock camera app gives more or less normal exposure. Controlling exposure from third-party camera app ("A better Camera", Camera360) seems impossible, exposure stays on highest level. This actually makes camera almost unusable;

- tried to add APN for mobile network, but after pressing "Save" screen returns back to list and it's empty, nothing saved;

- my Plantronics Legend headset has a sensor, when I wear it it routes sound to headset, but if I don't wear/take it off, it routes sound to phones earpiece. But it seems unable to switch destination on this ROM, so if headset is connected, but I don't wear it, sound doesn't go anywhere at all.

Aside from aforementioned, really like to have a KitKat goodies on my good-old device.

Thanks again.

[Galaxy Tab 7.7 Android Development] 3l1k:
I installed this rom on my tablet and have issues:

-battery life is very short - i discover that process 'cell standby' is eat my battery even in airplane mode even without sim. Even with stopped phone services.

-screen colors is disgusting. Looks like overbrighted and oversaturated, acid. I try to tune colors with app but have no luck.

So i returned to pac-4.2.2 - imho best rom right now. But wifi work better in 4.4. So there is no perfect rom right now.
[Galaxy Tab 7.7 Android Development] rebski:
I don't use this on a regular basis so I have no knowledge of the battery life. Sorry I can't be of help there.

However I can confirm that I experience no screen issues with colour or anything else. My screen is normal.

As for the video playback issues, could this be remedied with a codec pack, I wonder? Witness the Dice Player capability once it had access to a specific file. Could that hold true for the other players?
[Galaxy Tab 7.7 Android Development] L_o_k_i:
[MENTION=2867550]3l1k[/MENTION]

I found also the colors to be oversaturated. So I tune them by changing the values of 'mode' and 'scenario' like in this link. Now I have 'mode' = 3 and 'scenario' = 2.

I also had a problem with battery life. The problem was Google+, so I disabled it in settings/apps. But it can also be the mediascanner service that drains your battery... I have it some times... Check with betterbatterystats.
[Galaxy Tab 7.7 Android Development] 3l1k:
Thank you for tip with mdnie - i choose scenario 4 and mode 0. I'm disable google+ but this don't solve a drain. I discover that process 'cell standby' is eating my battery but don't know how to solve this yet.

While it does not bring us any closer to a solution to the video issue, it seems that we are not alone.

Over on the LG 8.3 forum they are reporting similar experiences with KitKat

The fact that the experience is widespread gives hope that a solution may be forthcoming.

[Galaxy Tab 7.7 Android Development] rebski:
The latest version of MX Player Pro seems to be satisfactory and plays all the video files that previously were giving problems. It may mean toggling between hardware and software decoders to get results in both audio and video but the main thing is that it works.:good:
[Galaxy Tab 7.7 Android Development] andyaikau:
Thanks for the great ROM.

It performs well but my only problem is the battery life on my tab. I use my tab as my primary phone. So the battery life is important for me. during my first few days i figure that the battery life is too short. I remove my sim card and left my tab in seep mode. I manage to get only 8 hours of life only without any usage.

anybody experiencing this?
[Galaxy Tab 7.7 Android Development] ngoonee:
Not my experience. Something is keeping your tab awake, use betterbatterystats (search XDA) to check what it is. With heavy use I get 6am to 8pm no problem.
[Galaxy Tab 7.7 Android Development] ninekaw9:
This ROM build 16 May 2014 has serious bug wakelock boot_hsic that drain battery during sleep sometimes, the cpu doesn't go to deep sleep.Seem like this wakelock occur on some boot finishes, sometimes it doesn't. Just to report.
[Galaxy Tab 7.7 Android Development] andyaikau:
Thanks ngoonee for your reply.

After using this quite sometimes now, it seems that the Media and the Kitkat System(if iam not mistaken) that drain my battery. Sometimes it happen and sometimes its not happening. And one more thing, why is the Media is using so many battery power? After 11 hour plus of battery life, 31% is standby, 25% is media and screen. Is this normal?
[Galaxy Tab 7.7 Android Development] rebski:
For what it's worth, Media is sucking up my battery too but I am on Stock 4.1.2 ROM. There used be a way of stopping Media scan but that was broken with recent updates. Unless someone knows of an other solution.:(
[Galaxy Tab 7.7 Android Development] sergani:
THANK YOU!

Been searching for the perfect ROM, and this one nailed it!

Thanks to all those who contributed for this project and made it possible for our tablets to live on Kitkat, with unbelievably good high speed!
[Galaxy Tab 7.7 Android Development] p3dboard:
Media scanner is a funny beast. On my Galaxy S2 phone with a 64gb SD card, I have had this issue before. Normally its a .JPG or .MP3 that the media scanner considers slightly corrupted, and it just sits there looping on it. I have normally flushed all the .JPG and .MP3 files off my memory card (copy them somewhere) and after a reboot, the problem goes away. You can then try copy your .JPG and .MP3 files back and if you want to do it in sections and reboot till you locate the file that's causing the issue.

The Neatrom image for Android 4.1.2 on my Galaxy S2 phone had this CWM update patch which seems to eliminate the looping bug with media, for Android 4.1.2 on a Galaxy S2, but I don't know if it will work on the Galaxy Tab 7.7. I have attached it in case you want to look at it / play with it.

Edit - just had a similar issue on carbon ROM, I cleared the media storage data and rebooted, after media scanner seemed to behave itself again
[Galaxy Tab 7.7 Android Development] rebski:
Is there any way of stopping Media Scanner completely? It serves no purpose for me, I select media files individually via file manager and I just want to stop all of that useless activity.
[Galaxy Tab 7.7 Android Development] p3dboard:
In Carbon ROM which I am now using, you goto Settings -> Apps -> All Apps -> Media Storage and then choose disable.
[Galaxy Tab 7.7 Android Development] biopsin:
if it applies to kitkat then

# disable mediascanner

pm disable com.android.providers.media/com.android.providers.media.MediaScannerReceiver

cpu to deep sleep???

Using CPUSPY i measure my 1st tabs freq - with cm 10.1 version of 4.2 when my screen is off my tablet goes into deep sleep - According to CPUSPY. My tab can sit overnight and I lose barely any battery percentage. CPUSPY shows most of the freq under deep sleep.

Fresh Slimkat install with min gapps -

Using CPUSPY i measure my 2nd tabs freq - with slimkat version of 4.4.4 when my screen is off my tablet does not go into deep sleep - According to CPUSPY deep sleep is not used. My tab can sit overnight and lose a good bit of battery percentage and shows in cpuspy most of the freq at 200mhz.

wifi - data - location - all off

tried deep sleep battery app with no help

better battery stats show android os to be my biggest use which led me to cpuspy.

Are others getting deep sleep with this rom?? What am I missing??

I have two Tabs, one spare with SlimKat 4.4.4r1 and the other my main phone with Stock 4.1.2

I decided last night to run a comparison but messed up the procedures so I shall try again tonight.

What I have got for the moment on the SlimKat is Deep Sleep 8:11:02 92% 200Mz

I don't know how to interpret this but I hope to have a better comparison tomorrow.
[Galaxy Tab 7.7 Android Development] rebski:
Another attempt at Deep Sleep comparison last night just before I went to bed.

My methodology: Both tablets charged to 100%, both have WiFi Off, both have Airplane Mode On, both put to sleep by pressing the power button at the same time.

After 08:15:00 hours I woke them both up

SlimKat 4.4.4r1:

Deep Sleep 99% Battery Status 100%

Stock 4.1.2

Deep Sleep 83.6% Battery Status 97%

Does this help?
[Galaxy Tab 7.7 Android Development] Lt.col.johncross:
Which gapps are you using - I will reload and try again to even just get deep sleep for one second will be a start. Also any "special apps" being used to assist in the deep sleep? Thanks for the assist.

I am using the GApps file called Slim_mini_gapps.4.4.4.build.6-112.zip (this is not the link just the name) No special deep sleep apps or anything similar.
[Galaxy Tab 7.7 Android Development] foolcat:
I got similar issue too. I had full charged my P6800 to 100% at last night. And disabled the media scan. Then change to Airplane mode and till this morning. I found the tab cannot switch on since run out of battery. I checked the battery usage that it used around 4 hrs only. The detail information : 45% for media, 40% for MailDroid, 13% for screen and 2% android system.
