Amazing work, Daniel. Thanks so much for your effort.

My impressions on this release: battery life is AMAZING, a lot better than official firmware; I am unable to play any kind of video, Youtube included, that´s the only thing that is really bothering me since I use chromecast to watch movies from it; Incredibly fast and responsive; some screen tearing when browsing the web (using Chrome); I don´t know if it is just my imagination but the color scheme seems to be a little "off", contrast is a bit down; some reboots here and there, it doesn´t seem to have a specific reason.

Well, that´s it. Thanks again for all your work!

cm 12

Its super awesome we are seeing lollipop on gt6810 all though there were some fixes need for video decoding and others. I did try it out but all the roms I've tried don't quiet give me the simple stable experience paranoid 3.68 gives me especially with camera flash everytime its opened for new pictures to be taken and browser distortions which is hardly experienced in pa3.68. Looking at the paranoid rom, do you think lollipop could use abit of the old experince of paranoid just incase the new updates coming out of lollipop pose abit too much of difficulty?... I really would love to see this awesome lollipop interface you've given us a chance to experience on a paranoid kind of feel...u know... Also, compared to how light paranoid is, the kitkat and others seem to perform under alot of pressure. My tab practically gets really warm when watching a video on low screen light and a minimized volume. These things are scaring the crap out of me so I've reverted back to paranoid. Would love to have a positive feedback, hopefully... Once again, Thank you for the work you've done so far.. You're aweSome!

My laptop got stolen recently.. Really wanted to tinker with this new build. :p now I have to do that directly from my tab somehow...really depressing and stressful :( but all goes well, hoping for a better future with cm 12.. :cyclops:

I Need Multi-User Support

Thank you Daniel. I love it!
I hope that the multi-user support will be added in the next build. Your efforts are greatly appreciated.
Happy New Year!

very usable but not too stable,random crashes,auto restart,freezing
apps start fast but then lag a little
over all almost can be used as daily drive other than lag and random random crash and reboot

Some issues with 10th Jan build

Hey Daniel,
Firstly, thanks a ton for your hard work. I check this forum on daily basis to check out new builds if any. I really love your work. I am still using my 3 year old tab just because of you.

I have installed the the 10th Jan build. There is one major issue I want to report. When I leave the tablet on for sometime untouched on charging or anything. I come back and try to use it at the moment the screen never switches on. I have to push the power button and hard restart the device again.

It seems to be dying out after going into deep sleep and need to be restarted to start using again.

If I am missing some solution for this please let me know so i can fix this. Otherwise this new build and new kernel is awesome. Even the speed of device has tremendously improved.

Ravi

Great Rom

This ROM is by far better than kitkat on many ways...and its much more stable... So far everything works perfectly...the only small thing is, I think lollipop is abit too heavy on the tab 7.7. Cm 12, I'm really enjoying the feel... Thanks Dan.

So how can lollipop feel lighter but with the same features? In terms of its memory management, speed at which it can process one or more things at a time and considering where tab 7.7 is coming from, it doesn't seem all that simple...

Also, you we could tell you if there were any problems.. No distortion or anything but there are minor flickers which kinda scares me..I hope its nothing. The flashlight function don't work. Any gapps higher than the micro version, I get this error "insufficient internal storage-aborting installation'. I use the latest TWRP.

Is it possible to get a camera app with photosphere? I really love that function in a camera..

Everything else works just fine...WiFi works better on da kk versions and much better on da lollipop (cm12). Like I said from the beginning, seems the lollipop weighs the tabs overall performance down a lot.. I couldn't find anything in the root folder that helped so maybe you could teach me a thing or two about that area on android lollipop...

I have a tab gtp6810
Thanks

And o, the previous ROMs that some people complained about the charging running down the battery instead while plugged in and running at least one app like the browser... I did a power supply reset in the terminal... I don't know if worked but I'll give a feedback here if I see any improvements for everyone using any of Dan HK ROMs...

fifth try

Well, I only installed the cm12 without gapp.. I'm going to fix in the apps I want from the gapp... So far, running abit smoother than with gapp install along cm12 together... For the torch, I'm going to take the one from cm11 and try make it a system app.. Also, the camera...the flash only works when every time you open anew and take the first picture or select through the flash settings.. Just like all the previous ROMs from carbon to slimkat... Only PAC and paranoid 4.2.2 are the last that works the way you would want..but graphical interface ain't as good as this..hehe

---------- Post added at 09:10 PM ---------- Previous post was at 08:57 PM ----------

The dalvik heap size allocations...do they work through the system's available storage, ram or some separate caches space separated? I sort of change those area abut..there was abit of change around the graphic performance and processor...couldn't really tell but it felt abit different... Will those sort of changes affect anything negatively as well somewhere in the custom firmware? I want to be careful I'm not doing anything wrong...

runs good

I think it run better without gapp....only difference is, you won't have all the Google service interface eating away your battery and stuffs power related.. Also, recent app button, the apps take abit more time for the close sign to appear... Its basic issues still remain like the missing torch function But in all, it works very good.. U think this new cm 12 could actually become an OS on it own? I've been going round the web seeing as how Aroma installer are popularly used with different cool installer interfaces... Cm12 so far ROCKS!

For those having battery charging problems, get the stock recovery (it worked for me) and flash in the pit file for ur device as well, seems to help somehow...you can try sbl bin but I mean, its just an idea... I lost my laptop so I can't manage going back and forth from friends houses all the time...

few cm12

Bluetooth..pair and connects with some av control. Didn't realize the tab was my PC now. Sending files..-"no bluetooth device found" (while paired or with the extra a/v connection).

Tab turned off, trying to charge under twrp 2.8.2.1, "battery draw jpg cannot load" or sth like that. Not sure what that means but a white one shows charging after the error.

Mobile Odin can't see nor access external SD.

On first install, Google search appears after turning off in launcher settings, open recent apps tab (show up here insteadv big and white), go back and turn on in setting,"heeeyyy, you're here!! Welcome back to my screen..lol".. So its not ICS version I see on the home screen.

Live paper on, turned on Bluetooth first time and device restarts. Surfing over 5 tabs on browser at the same time, restarts. Also, using an app like torrent to download one file while watching a movie (tab get very warm & freezes completely and unresponsive till I keep on power button till it restarts the device)

But I'm only testing all this with a fresh installation and gapp 5 beta 12 nano. I haven't changed any settings at all. Just want to help out with more feedbacks on overall performance.

Most responses to apps opening and closing can be slow in moments where about at least three or four apps have been opened.. So I have to manage an app at a time while clearing my recent apps. And surface a page or two unless with a different browser like UC browser, its okay.

Colors, everything feels cool. Flashed lollipop font and system sounds (don't remember where I got them but I'm sure it was on xda). It sort of felt like I was using the kitkat version that's why I changed them. Runs and feels abit better than my first time install cm12.

I don't know if there are any memory forced to leak but maybe you could hover around to see if something's is abit off about it from what I've said so far.

So between recovery and custom ROM, seems there's some unstable thing going on from within their interactions... I don't know, maybe recovery also needs an update....I guess...?... Well, you're the expert so these are my user experiences so far... Will let you know if anything else comes up

This new lollipop really is different. I can't even tell in the lib files are supposed to be in the apps or lib folder or both when trying out an app like the latest Google camera. I've tried but I only get as far as paranoma and it stops working at photosphere. Sometimes it opens but da circle has no use when the pictures are supposed to be taken. Read from file to file, I must say...I have never been this lost in android...hahahahaha

updating on cm12 issues that could help, hopefully

Lollipop looks light but feels heavy on performance i think cos of how much memory it over-uses.. Maybe its the kernels or sth so I'll wait for what Daniel will help us with to understand more (thank you again Daniel. U're awesome!)

What I noticed today was, when the memories goes to its limits in usage is some areas I think, the tab glitches, slows down abit and restarts if anything else opens... I was only watching a movie series (homeland TV series) from my 32GB SD card, and downloading a ROM from media fire with all my apps closed but the system running. No other recent tabs were opened.. Before I continue, I limited the memory use so between 5mb to 256mb does seem enough unless u r da type that multitasks a lot more (but that should not the case, right?...weird tho). I did this cos when I increased it, with a bit extra apps (about 1 or 2 etrxa apps running), its kept either freezing badly or restarting. So I just had to test this to see if its me or this new OS is going to be hard to work with...

Secondly...I use MX player a lot... Sometimes hardware works but when switched to software decoding and back to hardware, suddenly hardware is not supported unless I close the current video or app itself and start again. But will still fail at hardware decoding and sometimes restarts unexpectedly during software decoding.. Too much info?...haha... Naaah.. Lol

JESUS! The cursor is abit difficult to move around with a huge finger that covers it completely...lol

In case you are wondering,"where did this guy come from"...I assure u, I have been a fan of xda for about a year or two maybe or more cos I remember using my first tab its been almost or over two years. I only recently joined cos android has fascinated me in many ways and by having alot of great customization options and being an open source if I may add... I'm happy old devices get to meet the challenges that people have doubts on.. I'm grateful that I still use some of my old devices with a lot of confidence...

hi
I installed this cyanogen rom on my P6800 , but in "Rom Manager" app i couldn't Reboot to Recovery.
when i press "Reboot to Recovery" my tab doesn't reboot!!!!!!!

Really? How did you install it? And did you do a factory reset after install ROM or clearing cache and dalvik cache? Have u tried a long press on the power button to shutdown first?

As for ROM manager, I can't say for sure I can help u with that but I also noticed some things like mobile odin don't fully run all its functions on my tab p6810 with the p6800 kernal I found for mobile Odin to work o my tab.. I can't see the external SD unless i copy da file I want to use to the internal storage... So cm12 is still a working progress I guess.. Refer to the original cm12 post...Daniel said sth about the we probably will have to end up with our own new custom kernel to use I think due some out dated resources...For now, if no options works for u... If u know how to open the tab gently to take out the battery's connection and back in to enable u go into recovery to do a back up just in case... The u can sort out the ROM properly...and only if ur tab doesn't allow u to shut it down manually... At ur own risk..u can watch YouTube videos on how to handle ur tab p6800 with care when opening..

I've used twrp recovery and cwm recovery (which cwm needs to be rooted before flashing ROM), they all worked well for me so far.. A feww issues I've already pointed out but could be sorted eventually..

I searched da web for info and made a few changes to my build prop. Would share with u if interested...but remember, I'm only using the WiFi version of ur tab..

---------- Post added at 02:20 PM ---------- Previous post was at 01:57 PM ----------

I think the last cwm recovery works abit better (if in case u have charging charging issues and don't want to use the original stock recovery).. U flash that and root ur device through the recovery, restart recovery to root or fix root then install cm12 with mini or nano gapps 5.0. Battery draw is missing in ROM but don't worry, it will still charge.

I want to share my super su which I flashed to root the device but I can't get the upload button to pop up any window to find the file on my tab in the system's browser on the cm12. Well, all the same...Good luck!

I wonder if this is what they call a memory leak...

Three words...poor memory management... For an old device, lollipop settings over use tab hardware resources..though its performance is better in terms of gaming.

OK...I said I made a few changes to my build.prop...well, here they are:
#
ro.sf.lcd_density=180
ro.HOME_APP_ADJ=1

#
wifi.supplicant_scan_interval=84

dalvik.vm.heapstartsize=7m
dalvik.vm.heapgrowthlimit=49m
dalvik.vm.heapsize=294m
dalvik.vm.heaptargetutilization=0.72
dalvik.vm.heapminfree=788k
dalvik.vm.heapmaxfree=7m

dalvik.vm.lockprof.threshold=600

These are lines I made changes to (p6810)

******
I'm using nova launcher as system launcher
Flash some L fonts and sound I found on YouTube
And boot animation

Just to try get it to feel like lollipop as much as possible..


I notice a white line that flickers between long minutes like about 45mins during a movie playing on my MX player.. It also happens during charging the device when running twrp I guess...i see that on my lockscreen when on landscape mode...don't really know what that means...but I take out the charger for some time and plug it back and it stops for a long while but I switched to cwm.. Da MX player thing still shows though..

I removed that performance tweak app... Can't risk overheating...sorryyyy...I get scared a lot when I know my device hardware has its limits and way of coding to the responsiveness to whatever android versions out there....and I guess it all depends on the hardware make or build period and its sources..

Well, catch ya'll later... Still waiting for kernel and/or some ideas...

Cm file manager don't do much aside from viewing files and folder or install apps..

I tried material manager pro...that too crashes when I try to select everything at once in a folder...have no clue what that means either but will make time for the apps later.. Right now, cm12 needs a good workout till I feel its stable enough for extra updates from Daniel and others who enjoy helping g out....

PEACE!!

tasty lollipop

arrrghhhh! Wish I had an 'F5' button on my Google keyboard!!!

Just messing around..lol... But seriously though, you use it for abit with different apps running and closed...then remove all recent tabs...restart, you have most apps you opened which a lot are related to Google running as background processes......mmmmm....didn't realize the system takes me abit too seriously...Haha
So now, I have 'ccleaner' and 'the cleaner' installed. Ccleaner runs... 561.6mb ram of 770.97mb used. Okaaaay..........analyze....clean processes, empty folders, cache....no changes to memory.....awkward...lol..

Now, 'the cleaner' app- analyze, 197mb or sth to be recovered...nice! - 'clean'.......384.84mb in use...shows in ccleaner....wow!

This is.....sth......

Ok so, system bootup........Google+ and YouTube are background processes.... Sometimes 'music' pops up....weird....I.....don't think I'm ready to dance just yet... But after a while they get tired and leave, leaving YouTube behind.......maybe it wants me to watch xda videos....... Ok, so Google app pops up when I've l've literary stopped all its functions... I haven't force closed it, no no no...well....not yet but I will....

I once saw Google service and Google play service pop up...are they related?

Also, I would like to make guess or assumption; I think it takes abit longer to load everything compared to previous ROMs... Even when its already booted to home screen..

Ok, so some was last night's observations.. I think this gapp is going to make me saaad. :(
Will use only cm12 without gapp and run the Google apps manually instead to avoid multiple background processes at once...gms core.....interesting and can be quiet a strain...o well.....laterrrrrrr
