[DEV] Galaxy Tab 7" LCD screen tuning

Hi Galaxy Tab owners!
Samsung was so kind and sent me a Galaxy Tab (SHW-M180S) to help me developing for it. Thanks Samsung Mobile Korea
That's why, only a few hours after receiving it I introduce support of this device in my research project app named Voodoo Screen Tuning R&D, available for free on Android Market.
This app is very much experimental and not a final product. See it as an internal leak from a R&D lab. But as Linus tells: release early, release often
Please take a look at the app description, and have fun testing this app!
I need your feedback, so.. see you soon.
Note: support starts with snapshot #31.

i have a sch-i800. will it be supported?

Wow this is dedication, an unsecure kernel and an app in less then 5 hours, gratz
Anyway, seems to work fine here, colors are more bright by clicking on "dev", not sure what you made but it works.
Thanks.

Awesome, Do you have a GSM or CDMA tab? Can we expect some custom roms in future?
Great to see a new dev join section
Will give app a try later and give feedback, thnx

Is CM7 for the tab using yet another funky out of nowhere name as device name?
I'll know if you send me a report

Any tab.
However I'm not a ROM guy − if I have a lot of respect for those who deodex and assemble ROMs all day long its extremely boring to me and I prefer doing things not done yet

Snapshot 32: accept "galaxytab" Build.DEVICE from CM7

Thanks, now it works. But I don´t get it, the link brings me to the android market webpage, when I download it there it works great, but when I download in the Market App it doesn´t recognize my device???
Anyway great work! Hope to see more ...

Give a try to snapshot 33
With the overlay interface, you'll be able to see very clearly the effect of enabling/disabling CABC (Content Adaptive Backlight Control)
CABC is enabled in default Samsung settings, disabled in "dev" preset.
Note: much more than backlight is affected, IE the whole response curve with Samsung's advanced & complete CABC implementation.
Example: with a low contrast & dark content, then in the settings (white background)

Is it possible that it doesn't keep settings after a reboot?
Because when i reboot it seems to me that it return to Samsung setting and if i cleck on dev i see the difference.

Auto restore at boot is not yet implemented.
So far I'm thinking about how to write cleanly the codebase to do that despite the variety of device supported, sometimes with "presets" (combination of settings already present in kernel), sometimes with "profiles" (color calibration profiles built from scratch using reverse-engineering and a colorimeter).
I want to write only super cleanly designed code in this app so.. no rush

Ahhh....no worry, i thought it was a bug so i've reported

Multiuser on phones. (with different use)

I think that the multiuser feature should be made to work on mobile phones. However, using it actually was multiuser would be ridiculous butit could be implemented as a "Phone mode" feature. You could have a "Work" mode with business apps and stuff, and also the "Home" mode, which you would put more fun things with. It would be kinda nice to have a way not having everything jumbled together.

If we can have different security settings for it then it would be really cool.
Our company email requires a unlock code or password and I don't won't use one in my private time.

Thats one of the Blackberry 10 features, exactly like u just described
Sent from my Galaxy Nexus using Tapatalk 2

oh yeah i know
Yes I am quite aware that it's a bb10 feature. I just think that they (Google) should have thought more about the idea and put it on the phones. I think the ROM developers will do it because cm10 has profiles and they would eventually change the original profile feature with what I'm saying. Maybe when they make a 4.2 ROM. I hope someone at Google reads the thread sometime.

I'll have to check on that.

[Q] [CM10.1] Android 4.2 pretty slick; multi-user mode?

Hey guys, so I took the plunge and updated from CM10 to CM10.1 today (20121218 build) and I am here to report that Android 4.2 is pretty slick. For those that are going to update, here are a couple of things you might also see:
1. My wireless connectivity was a little sketchy after the update. I had to go into the list of APNs and restore the defaults...after that, everything was fine.
2. On startup, the clock app crashes. In order to stop that (and set new alarms) I had to clear data from the app.
3. If you want to enable developer options, it's hidden now and has to be enabled from the about phone menu.
4. The new features are pretty cool, IMO.
Now my million-dollar question:
Android 4.2 is supposed to bring multi-user support, but I can't find it or figure out how to enable it. From the quick settings panel there is a tile called user switcher, but when you select it it brings up a screen that only allows me to select the current (default) user. There's not much written about it yet...are there any knowledgable peeps out there that can help a brother out and drop some knowledge?
Thanks for reading!

Just guessing. That's all. I'm thinking its a Work in progress.

I'm almost certain that the multi-user support is for tablets only, as for cm 10.1 im dying to try it but I think I'm going to wait till most of the bugs are worked out of it before I take the plunge.

http://10.1.cmxlog.com/?device=d2att here's CM10.1's changelog. It appears multi-user is to come with the next nightly 12/19. Btw questions belong in the Q&A section.

Nice! Thanks. At least I don't have to wait long. I'm stoked to try this out.

About phone-

I don't have any options in about phone for developer. Can you be more specific sir?

IIRC: Multiuser is a tablet only-feature in stock Android, highly likely due to a Nokia patent regarding a multiuser function for phones.
Though that might not stop mods from appearing, that enable it on phones, but I don't know if CM will support it on phones in an official release...

I think you're misreading the changelog. This change is to allow the su binary to support multiple users, not to add multi-user support to the ROM in general.

fails to mention the up in pro mode iso to 3200 in the cam and 30 sec shutter vs 10 on android 9

Nice to know the camera got those cam speed and iso aditions, I am curious about the starage handling, as I previously read an article here in XDA that files created by any app would be available only for such app, the author saw this as a negative feature, I would like to see how that impacts overall file usage in real life now that android 10 is officially rolling out

The article does not mention what they crippled ...

Inquiring minds want to know. lol

External touchpads support is broken (both usb and bluetooth) - they don't work/gets recognized as mouse HID as it was on Android 9, currently more like some kind of touch input. Therefore mouse cursor acts strangely when using touchpads - it is way quicker in one plane (e.g. horizontal) than the other (e.g. vertical) which makes it usless.

The update does cripple support for Good Lock which is a huge drawback. You can no longer customize how many rows or columns appear in the quick settings. Many Pie themes are no longer working in 10. On the positive side, battery life has much improved with about 20% more battery at the end of the day. Certain apps such as Instagram will now switch to dark mode if you have it enabled systemwide. For those eagerly waiting, I'd say you're not missing out on much.

Every new version of Android on samsung starts without full support of every goodlock app. It will be the same thing for Android 11. They will update then eventually

One thing for me that kills the A10 update is being unable to Turn Off "Restrict Backgroud Data" on Power Saving Mode
I like to throttle the phone to stop losing battery as quick - Reduce Processor to 70% / AOD Off etc...
With the latest update they have removed the option to do this however when you activate it - It says be default that it is going to be switched on :/

Anybody faced the issue of KLWP not fully working after the update? I can set the wallpaper but the "click to launch app" does not work.

That didn't come with Android 10 though. It's been there. Maybe it came to other devices on 10 but Samsung already had that feature.

HOLY Crap! You are absolutely correct! OMFG! Wish I had found that long ago!

I hate it when programmers change things just so it looks new and improved.
Zero-dark-thirty is NOT the time I want to discover that the snooze button on the alarm clock app has been "upgraded" and moved. Groggy/grumpy/sleepy self turned the alarm off this morning instead of just snoozing it.
Why do they keep effing with my snooze button?!?

[Xposed] (Security) Disable Quick Settings Pulldown on Lock Screen

This is just a simple Xposed module that disables pulling down the notification shade / quick settings tiles while on the lock screen (but doesn't break media player controls on lock screen). Only tested on Pixel 4 and Pixel 4 XL on Android 10 (more on this later).
Background: This has always been an annoying aspect of Android for me, and it's dumb from a security standpoint. Being able to pull down the quick settings tiles on a locked phone is dumb. Why hasn't Android natively built this in yet? Using this and Gravity Box to disable power menu on lock screen makes me feel a lot better in the event my phone ever gets lost or stolen. It's dumb that anyone can steal your phone and immediately toggle your settings (turn off WiFi, Mobile Data, toggle Airplane Mode, etc) and/or turn the phone off... I've been spoiled for years by the OG HTC devs (particularly LeeDroid and Team Venom) and their ROMs with these features baked in, so it's back to using Xposed to fill that gap for me and my wife, lol. Anyway, I pair these mods along with the Lockwatch app from Play Store and it gives me more peace of mind. Hey, anything to increase the chances of recovering a lost or stolen phone, am I right?
Credits / Technical Details: This module is based off of char101's published Xposed Repo module, and all credits and thanks should go to him. This is the first app / APK I've compiled so it was a nice learning experience, but it was all based off of his source and I really just needed to remove a few lines of code to get it to work properly with our phones. His mod worked fine and disabled the quick settings pull down on the lock screen, as intended. The problem was that it would also prevent media player controls from functioning (and I would assume other possible functions as well). To fix this, I just removed DISABLE2_NOTIFICATION_SHADE references from the code, leaving DISABLE2_NONE and DISABLE2_QUICK_SETTINGS untouched. The mod still works perfectly as intended. Only tested on Pixel 4 / 4 XL on Android 10. I'm sure it would work on other devices as well.
I really just did this on a whim for me and my wife's own phones and wasn't planning on sharing it, but I figure other people may have also wanted this for their P4's as well, so enjoy. Again, all thanks go to @char101!
Installation:
- Download .APK file attached to this post.
* If you have char101's original module installed already, I would highly recommend uninstalling it first.
- It's an Xposed module. Install the APK and enable in your Xposed Manager.
- Reboot and test.
Based on: https://repo.xposed.info/module/com.github.char101.qslock
Source for modified module: https://github.com/i5lee8bit/xposed-qslock-P4mod

Just noticed something that worried me at first, but turned out to be nothing of concern afaik, but in case anyone else gets spooked by it: I just noticed last night that if you launch the camera while on the lock screen, you can still pull down the notification shade. Same can be said for other apps that can be active over lock screen (e.g. Phone app during active call).
However, the quick settings are still inaccessible while locked. The notification contents that do show will follow the same rules as your settings, so if you have it set to hide sensitive notification content (which you probably should... otherwise 2-factor authentication is extremely pointless if your device were lost or stolen), you still won't be able to see the notification content itself, just that there is a pending notification for that particular app.
I hope you're finding the mod useful, for anyone who is using it. Please let me know if you find any issues with the module, thanks. I'm by no means a developer, but I have more free time than usual for obvious global reasons and it's a fun learning experience while the free time lasts. =)

I've been using the original NoQSInLockScreen, and while it did the job, it really bothered me that you couldn't use media controls on the lock screen (or expand notifications).
This mod took care of that problem. Really happy with it!
Just wanted to say thank you for putting it up!
Tested it on Android 9 (LineageOS 16.0).

Just wanted to stop in and say thank you for the awesome edxposed mod! I appreciate the extra security and hope you're doing well!

Just wanted to let you know, as a fellow (now former) user of this mod, that I found a better way of doing this! So just thought I'd share:
Using GravityBox app for EdXposed framework you can simply define which individual QS tiles you want to secure. That way you still have access to the QuickSettings pulldown menu from the lockscreen (unlike this mod which disables it altogether), but things like Wi-Fi, Location, Airplane Mode etc. are secure and not accessible until you've unlocked your phone. It's a much more practical and elegant solution in my opinion.
Check out my post on this from Reddit where I describe the steps if you're interested:
https://www.reddit.com/r/LineageOS/comments/gdvwml/securing_quick_settings_tiles_on_lock_screen/

Can't wait to try, does your mod support Android 11?

I completely forgot about this mod, haha. But thanks for letting us know!
As @nanquan mentioned (a long time ago, lol), you can also achieve (essentially) the same thing by using GravityBox. It is indeed a more "elegant" solution, and since I already use GravityBox heavily, I now just use GB's tweaks to lock down the main comm tiles.
But I'm glad this still works, for those who still prefer to use it for whatever reason. I can see it still being useful if you have a lot of custom QS tiles and want to keep it all locked down.
