I don't think you can trust AnTuTu's numbers unless you run it a minimum of 6 times (more is better) and throw out at least the top and bottom 2 results. After lots of tests, my

median

(not average) score is about 13850 but I've seen 14200 once and 11120 twice. Just now I ran it twice after restoring from a nandroid backup: the results were in the 12200s. I powered down, powered up, and retested twice: this time I was in the 13900s. So, if you don't like your results, reboot and retry until you do ;)

No one is changing "the kernel", i.e. the code that runs the machine, because no one has the source to build a new one. What does get changed is the boot.img, which contains the kernel and a bunch of files that tell the system how to set itself up after the kernel loads. Changes to those setup files (init*.rc) tend to have less of an effect on the system's raw performance than on its configuration.

I started with the stock boot.img then made minimal changes because there wasn't a lot that could be changed without a new kernel. I disabled the service that overwrites CWM with the stock recovery, and added logging and init.d support. The most significant changes I made allow ADB to run as root - something it couldn't do in previous versions. That's about it.

BTW... CWM recovery (or any recovery, for that matter) is simply an alternate boot.img. After loading its own copy of the kernel, it launches a small recovery program rather than the full-blown system. Since it's self-contained and operates independently of the main system, it can't have any effect on the main system's performance (other than the changes you make to the main system while using it).

Finally made some time to load this up today. Very Nice! Thanks so much for your efforts!

One quick question.. Is there a way to get rid of that dang screenshot button on the nav bar? I hate that thing..

Thanks!

MrSimmonsSr check first post under enable tablet ui.
[Android Software Development] MrSimmonsSr:
Thanks for trying to help me.

I did follow the directions for enabling Phablet UI. Are you saying the screen shot button would have been gone if I'd enabled Tablet UI instead? Maybe I did something wrong?
[Android Software Development] mavpts:
I got rid of mine that way. Enabling tablet mode anyways.

Charging the battery

Hi. ever since I flashed DoPa when I power off to charge, plug in the charger "Hisense" pops up and remains eliminated on the screen. If I hold the power button until the screen is totally black, plug in the charger, the tablet will not charge.

It wasn't like this before. anyone else? is this a hardware, software, or "me" ware issue? Should I worry about it?
[Android Software Development] gberpa:
Am now running your ROM after first delinking apps from Link2SD and unmounting folders in FolderMount. This time I didn't lose the apps I then reactivated links after installing ROM . FolderMount worked and remembered my choices from before installing ROM. Things I've tried work. Nice! So many options/choices using Xposed Framework, Gravity Box, Apex Launcher! I'll need some time to sort it all out. For one, I somehow chose something which removed the names from the apps in the drawer. Anyone know how to restore these? Also, on reboot, it launches in portrait mode and autorotate doesn't seem to go on until the screen is unlocked??
[Android Software Development] PesSarmiento:
Hapens the same to me yesterday, when my tablet dies without battery. Same as you.
[Android Software Development] snyperr:
I noticed this as well.
[Android Software Development] gberpa:
I usually charge when the S7 is either in 'sleep' mode or when the screen is off, eg after a short push on the power button. I do this because I'm running Link2SD and its a pain to power down and have to remount the links. No problems with the DoPa ROM or Xboxexperts and DoPas rooted stock either 6.0.2.11 or 6.0.2.20. However, as I have a 'flaky' micro USB port that doesn't always connect to my cables, I am always checking. With my original stock and rooted stock, when the cable was plugged in with the noted modes, the unit recognized the cable plug in by going to the lock screen and I could see if it was charging. This isn't happening with the new ROM-the screen stays off.

I'll try powering down overnight and charging with an almost completely charged unit to see if the problem you people have is happening.
[Android Software Development] kc12:
It's happening to me regardless of how much juice is in the battery when I put it on the charger. I power it off to a completely black screen. As soon as the charger is connected the "hiSense" illuminates and remains there - this is the only way my tablet will charge. And it gets pretty hot doing it too.
[Android Software Development] gberpa:
I just powered down and see that Hisense screen when I plug it in. I held the power button until the screen went black. At 88%, will see it it charges overnight.
[Android Software Development] kc12:
thanks, appreciate it.
[Android Software Development] dolorespark:
Now that you've pointed it out, I'm seeing this too. I hadn't noticed it before because mine is almost always connected to my PC. The tablet's behavior when being charged from a USB port is different than when it's attached to the AC adapter. (Have you ever noticed that on the Battery page in Settings it tells you the source of the power?)

I reverted to the stock 6.02.20 update ROM (no root, CWM, etc) and it appears to work correctly: after a few seconds of the Hisense screen, I get the battery image showing the current charge level, then it goes off. I'm puzzled by this problem because - on other tablets, at least - the battery image is handled by the bootloader, and that hasn't been changed at all by my ROM. I'll keep working on this until I get it fixed.

That change in behavior could be caused by a setting in GravityBox. Since I'm on pure stock right now, I can't confirm this but I seem to remember a setting under its Power Options to have the screen remain off.

Bluetooth transfer files...

I have been successfully able transfer insignificant files(pictures, non apk files and others) from tablet to laptop(windows system) and vice versa.... I wasn't able to test this with Dopa rom until last night, it pairs but when you start to transfer files from laptop to tablet it gives me an error of similar to "you aren't authorized to transfer".... will try to capture the exact error when i replicate this error. Thank you....
[Android Software Development] gberpa:
My S7 did not charge normally overnight. It basically kept the sane level when shut down. It is definitely different from stock.

I checked my Gravity Box settings. Under Lock screen, I have 'enable rotation' and 'quick unlock' checked; under Status bar tweaks, 'battery %' is checked; Navigation bar settings unchecked;Power tweaks has only advanced reboot checked; display tweaks. Has allow all rotations, solid black background , CRT screen effect off checked . I am going to uncheck the CRT one before rebooting. There also there is a setting 'Unplug turns on screen' which currently is unchecked but am checking it before I shortly reboot.Phone and Miscellaneous tweaks are unchecked.Media tweaks have safe headphone volume, expandable volume panel and link ringtone and notification volumes checked.

I will make the noted changes, reboot and attempt charging both from sleep/lock screen modes and with uno shut down.
[Android Software Development] kc12:
thanks. I appreciate all the hard work you are doing. I love the ROM and how it performs.
[Android Software Development] gberpa:
After rebooting with the Gravity Box setting 'Unplug turns on screen', the S7 charged ok from the sleep/screen lock modes. When I powered down and inserted the plug, "Hisense" text appeared and it is(hopefully) charging

.

I really like the feel of the new ROM. Thanks again, DoPa for your efforts. I still need to learn more about the 'extras' . I somehow 'lost' the landscape mode std Apex bottom icons. They do appear in portrait mode.

Update- It did charge a few % in powered down mode with Hisense logo. As I leave my S7 charging while home, it is now in my normal charging method in which I plug in in screen lock mode, check it is charging and use a short press on the power button to shut the screen use. This, too, is ok.
[Android Software Development] dolorespark:
OK, got it fixed. The problem was with a very standard Unix utility (cpio) that's used to package the boot image. The version I have produced 3 bytes of "meta-data" that were different from the stock boot image's. When I patched those bytes in my version to match stock, it worked correctly.

I'll post an update zip sometime late on Saturday that you can use to replace your boot image without having to reflash the whole package.

BTW... the reason it gets so hot while recharging when the tab is supposedly off is that the processor is actually running full-tilt because of this bug. Until the fix is in place, you'd be much better off to leave the tablet on and simply turn off the screen when charging using the AC adapter - it should generate much less heat.
[Android Software Development] snyperr:
Hi DP, thank you for continuing the development on our device and for fixing/tweaking things so quickly. It's very much appreciated!:good:

[Android Software Development] k8108:
I'm hoping someone can offer some help here. My Sero 7 Pro had some glitches and I thought I would do a complete wipe and load this ROM (dopa 2.0) again. Wiped data and cache in mounts & storage, factory reset, wiped cache partition and dalvik cache. Installed the 2.0 rom and the oc kernel. Stuck in bootloop forever.

I know it's a good download because I used it to install 2.0 over 1.1 when it first came out.

Repeated the process - still bootloop.

I know I made a backup when I first installed exboxexpert's rom when I first got my tablet, but when I tried to restore, it wasn't found.

Thought I would go back to stock. Downloaded 60220 stock from the OP. Wiped everything again. Loaded the rom. It asked if I wanted to save root and block system recovery. The first time I did this. When it stuck in bootloop, I loaded the rom again and chose not to save root and not to keep custom recovery. Still bootloop.

Any suggestions? I have rooted and loaded roms on my HD2, Nook Color and Galaxy s3, so I'm familiar with the process. I just can't figure out what is causing my bootloop here.
[Android Software Development] datfat:
Try with non-overclock kernel I had the same problem I went back to original kernel and it worked
[Android Software Development] k8108:
Problem - I don't have recovery since I tried to load stock ROM.

Update - stock recovery finally showed up on my Sero. I did a factory reset and wiped cache and voila! We have a working tablet again. Used xboxexpert's files to root and install recovery. Installed this great dopa rom and we are back in business!
[Android Software Development] JamesRF:
I've noticed that after flashing this my wifi keeps dropping connection. It's not the router because my PC keeps connected. Anyone else having this issue?

Other then that, great ROM thank you!
[Android Software Development] lexridge:
Does this kernel include exfat and init.d support?

Thanks
[Android Software Development] dolorespark:
I haven't run into that problem nor have others reported it. Except for a fix for people with invalid MAC addresses, the wifi stuff should be substantially identical to stock. Did you have the same issue with stock?

exfat: "no"; init.d: "yes"

.
[Android Software Development] lexridge:
Is not not just a matter of turning it on in the kernel config, then rebuilding it? Or is exfat just not part of the main stream kernel yet?

This might be a stupid question. Why is the tablet limited to 32GB sd cards? If a 64GB card was formatted to FAT32, would it see all 64GB?

I am still on a rooted stock ROM, but I am anxious to try this one. I wanted to try the 4.4.1 for this tablet, but I have got to have A2DP bluetooth support, and that is apparently not yet working on that ROM. I am assuming it works on this ROM, since it is based on stock.

Thanks

Near the end of the taktiK thread [MENTION=282573]davepmer[/MENTION] has posted a modified taktiK R13 with DSP Manager ,a2dp and audio over HDMI working.
[Android Software Development] dgjenkins:
You are correct about the sd card. I'm using a 64gb card formatted to FAT32 in mine and the while thing is usable.
[Android Software Development] jerbear294:
I've heard that once you use 32 GB up on the card though the tablet will stop seeing the card correctly, is that true?
[Android Software Development] dgjenkins:
That's not my experience.

That's accurate.
[Android Software Development] jerbear294:
Nice! I need to buy a 64gb MicroSD now... The 8 gigs fills up too quickly, and the only MicroSD I have is 2gb...

64gb + FolderMount Pro = Overkill.
[Android Software Development] lexridge:
Okay, I am now running Dopa 2.0 at 1.5ghz. Very smooth and MUCH better than stock. I will give it a few days to check on battery life, stability at 1.5ghz, etc.

I looked at the last 10 pages of that thread and I could not find any mention of A2DP working on taktik. I would think that would be huge and would be posted in the original post. Oh well.

Thanks
[Android Software Development] ratyfu:
Dolorespark has fixed it and Dave has implemented the fix in his newest cm11 builds. The other Roms are based on Dave's kernel, so they should have it working too.

[Android Software Development] tomkatt:
Does the overclocked ROM have CPU controls like in taktiK?

Also, has anyone tested the HDMI output? Is Audio over HDMI working on this build?

Also, what version of GApps is needed?
[Android Software Development] dolorespark:
I thought it was available in the kernel but I just looked and didn't see any option for it.

Are you talking about DoPa 2.0? If so:

- no CPU controls; you'll have to use a 3rd-party app

- this is basically just enhanced stock, so if HDMI audio worked in stock, it works here (I'm pretty sure it does)

- the ROM includes the basic GApps and the rest are available from PlayStore
[Android Software Development] tomkatt:
Damn, that's a no for me. My tablet has some weird quirk where it only outputs to 640x480 over HDMI on stock. So far the only ROM that's fixed it was taktiK R8 and R9, and I was able to output to 720p, but R10 and up broke whatever fixed the output.

Guess I'm stuck with taktiK R9. Not the end of the world, but I don't have BT Audio or HDMI audio right now, and wifi needs a reboot if you disable it (it won't turn back on otherwise).

Eh, I'm learning to live with it at this point. The tablet's good for what I'm using it for (old console emulation mostly), but quite frustrating at time swith all the little "quirks" it's got.
[Android Software Development] lexridge:
I am unable to get the OTG USB working. Is there a trick to this? I have tried a few USB sticks, both formatted to FAT32. My phone sees them fine (SGS3), but my tablet cannot.

The disk is available at /usbdisk. Android's media scanner will locate music and photos on the disk for use by apps (I just tried), but I don't know if other types of files such as apps or zips are accessible unless you use a file manager like ES File Explorer with its Root Explorer feature enabled.

[Android Software Development] Hag77:
Just got mine yesterday in the mail (99 bucks on amazon!) Took me all of about 20 minutes to root and install this rom, so far so good! My question is- is it normal for standby battery drain (about 6-7 % over 12 hrs or so while I was sleeping/working and not touching it). If so- has anybody compared to the stock rom standby drain? I took a CWM of the stock rom, so I can go back and compare if need be- just wondering if anyone already has.

So far- this seems like a great value- espec for 99! I just really hope it holds up over time- it seems like some of you have had micro-sd / charging issues, and I've even read some accounts of people's that just start totally shutting off randomly.. For now though- I'm very happy w/ my choice and glad to see folks like dolores developing cool stuff. Just have that one question about the battery- stock vs dopa and/or other roms. Thanks!
[Android Software Development] tenxo:
Can't give you the comparison you seek but can tell you that is good drain. 6-7% over 12 hrs is just 0.5 percent per hr. that is good... At that rate it would last theoretically 200hrs or 8.3 days. Remember stuff is still on and running, so it's ready to come alive at the touch of a button so it has to drain some battery.

Like you my first step was to root and flash a Rom, as stock was lacking IMO.

Mine was bought for my 18 mth old boy so it has stood up well for the last 8 mths, of spilled liquids, jumping on it, throwing it, food all over it, countless drops from his height (3ft), and ripping it from the charger. It functions perfectly and handles every thing Jr. does on it, meaning multiple intensive games, YouTube, Netflix, etc...all running at the same time, never had a single lockup nor slowdown.

Great tablet+great Dopa Rom= EXCELLENT.

Thanks for the reply. My little ones will be using this as well so it's nice to hear that yours has passed some good tests.. One more thing (I'm sure I'll have more questions later). So, I installed my favorite media app- xbmc, and I guess I just expected that the softkeys would go away during video playback as they do on netflix, etc. Unfortunately they do not. Anyone know a good way to get around this for apps that don't have built in support for hiding the soft keys?

edit: found answer to my questions- looks like a lil root app called full!screen will do the trick!

Memoy Problem

I d/l FIFA 14 soccer a while back and it ran. I have Link2SD with most of my apps linked to a secondary partition on my

32 Gb card. Also, I use FolderMount for apps with large data files and they go to my external card.

When I try to run FIFA, it starts d/l the data and almost immediately I get an error message saying my external card is full.

There is only 9.2 Gb on partition one (of about 26 G) and 1.9 Gb (of about 6 Gb) on the secondary partition.

Attached is my storage into.

Can anyone tell me what might be the issue?

[MENTION=5094650]dolorespark[/MENTION] - Two questions: How can I delete Apex from Dopa? There is no option available to uninstall it anywhere and I can't even hibernate it with Greenify. I use Nova and wonder why Apex continues background activity.

Secondly, could you please make a patch to enable/disable the old screenshot button? I know many found it annoying, but it was great at taking instant screenshots. The current implementations, while good for static screens, are too slow if one wants to capture fast changing screens.

Thank you for all the wonderful, quality work you do providing up-to-date support for our Seros. Your time is greatly appreciated.

sero7pro: dopa2: xda app
[Android Software Development] dolorespark:
There are two possible ways. The less technical is to open Settings->Apps and select Apex. It's very likely there have been updates since the installed version, so select 'Uninstall updates'. When done the button should change to 'Disable'; if it doesn't then exit that screen and return to it. Where a "downloaded" app would have an 'Uninstall' button, a "system" app has 'Disable'. Try that, then reboot.

The other way requires using ADB. First you'd use the adb remount command to make the /system partition read/write, then you'd use adb shell to open a terminal session on the tablet. From there, navigate to /system/app and delete the apk (I'm away from my tablet but I think it's ApexLauncher.apk). Be sure to follow the instructions above for removing updates first or it will still be present (updates for system apps go into the same place as downloaded apps go: /data/app).

I'm afraid not. I didn't have the source code for SystemUI.apk when I made that patch. I had to decompile the app, search thru the Java equivalent of an assembler listing, then delete the code that displays that button. Under those conditions, there's no way to make any customizations. If you want the screenshot button back, you can pull SystemUI.apk from the original stock zip, then use ADB to copy it over the version on your tablet (just like ApexLauncher.apk, it's located in /system/app).

BTW... The ROM you're using is pretty old in Android terms. I've been releasing builds of newer versions for several months. The latest is here: AOSP 4.4.4 DoPa v2.0. It has some nice new features and I'll be updating it in a few days to add support for SD cards formatted with NTFS and exFAT.

I want to update but I'm a little hesitant. My sero is rock-solid stable with your 4.2 Dopa; only issue is slight headphone noise (wish I could fix that!). In your opinion, what features make upgrading worth the risk of problems (wifi, gps, battery, etc) I've read about? Is there any must-have software that requires 4.3+?

Thank you for your time.
