LineageOS and S-Pen power saving feature - Galaxy Note 8.0 (Tablet) Q&A, Help & Troubleshooti

How can I make the tablet automatically turn off the S-Pen detection whenever the pen is inserted?
I need this because my Note 8.0 is draining too much battery, only because of this. (I know the S-Pen layer is still on because I tested it with another S-Pen while one was already attached).
On the stock ROM, there is a "Power Saving" option under Settings -> S Pen. How can I achieve this on LineageOS 14.1?
This is my third Galaxy Note 8.0 (this time, a N5100). (The other 2 I had were retired due to broken screen).
I've been using CyanogenMod since CM10. And I just can't remember how I always got this to work, but I know it did (on all versions of CM or LA).

Is there at least any way to just turn the S-Pen detection off permanently by changing something on system files?

Any success bro?

Usually, only custom ROMs that are based on the stock ROM will have similar functionality, because they keep the components for device specific features such as S-Pen. LineageOS is built from AOSP, not the stock ROM, so it does not include device specific features, nor does it include the necessary Samsung framework to make features like that work.

Just wondering, do the custom roms like slimkat, omni, cm11 etc.
support the usage of spen?

They will all allow use of the S Pen, as it's considered either a "mouse" or a straight-up stylus. Don't remember which as I tried it out and went back to stock.
You don't get any S Pen gestures without disabling the click button for all apps, and you can't make a quick note pop up on removal of the S Pen.
Overall if you rely on the S Pen I'd recommend keeping stock. Just an opinion, though.

[Q] using a custom rom on Note 8 with s-pen

Hi,
I am a custom rom fan and use them in most of my devices. But with my Note 8.0 I only use original Samsung based rom.
because I don't want to lose Samsung features like S-Pen etc.
What I wonder is, with a custom rom ;
- is the s-pen supported ?
- is there an alternative to Samsung AllshareCast support ? (in standards this is miracast support. Do the custom roms support miracast ?)
- What would I miss from Samsung features if I use custom rom ?
Thanks.
The s-pen works and is very functional on custom roms however you need to find the right software to go in tandem
S note is only compatible with touchwiz based roms and Imo is the best but actual pens functionality and sensitivity is as sensitive on any custom rom

thnaks for the fast reply.
So you mean S-Pen works but S-note (app) does not work. That's good news because I don't use S-note.
But for example, I can use Adobe Photoshop with S-Pen ?
What else I miss with custom rom ?
and what about screen mirroring ? (miracast)

You may of misunderstood what he replied. Just to clarify....if the custom rom is based on Touchwiz then SNote will work fine otherwise it in most cases won't.
If the custom rom is based on Touchwiz you should actually gain more functionality and not lose any. AOSP roms will vary on what is working and what is not.

If I am not mistaken I believe that is confirmed working on civato's latest rom.
A little clarity:
There are ROMs based on the official Samsung ROMs, and they generally support all of the same features as stock but without bloatware and with additional features. Civato's excellent ROMs are a great example; they perform better, have more features (particularly kernel-based), allow the user to select which bloatware to install, and generally are wonderful. Consider it stock ROM fixed up. I have used them for nearly a year and can recommend them highly. This means you get S-Note, and Allcast I believe at this point. There have also been other apps that have been ported from other Samsung devices to this ROM.
Other ROMs are based on AOSP (Android Open Source Project) and do not include the Samsung-specific software. No TouchWiz, S-Note, or any app that depends on the Samsung APIs in their stock ROM. The Photoshop app that is shipped for Samsung crashes immediately on my OmniROM and I had to uninstall - I guess that it is calling a Samsung API. So now, with Omni-ROM I will be dealing exclusively with the world of generic apps, which is not a problem. The stylus works out of the box. To have an app launch when the stylus is removed it is necessary to add a non-free app from the store. This will also enable other features of the pen. There are stylus-supporting note programs (e.g. Papyrus) which work just fine. Most apps using a stylus should work (e.g. Sketchbook) unless they were written using the Samsung APIs, in which case that should be obvious in the store as they will be Samsung-only apps. Edit: if you like to use the stylus for general text entry then you will need to get an app for that as well; they are available - but the neat way that the Samsung keyboard can switch to stylus input is lost.
I have no knowledge of the Allcast issue, other than noting that there are apps available. DLNA is certainly available through any number of apps for any ROM.
You will find a good source of ROM info on this thread: http://forum.xda-developers.com/showthread.php?t=2630650

Both AllshareCast (Miracast) and Chromecast screen casting work fine on the most recent @civato ROM's (FlexNote 3.0 and FlexBurst 1.0). This app and the official app are required for Chromecast screen casting.

Hi,
I would like to make some clarification to my question. By "custom rom" I meant "non-Touchwiz based" rom. Of course, Samsung/Touchwiz based roms do support everything related to Samsung APIs.
So my question is;
with a non-Samsung based rom, shall I be able to use S-Pen with 3rd party apps ? (like Adobe Photoshop - not the one distributed with Samsung devices but the commercial Store version)
Also does miracast work with them ? (not DLNA , real screen mirroring)
Thanks.
Yes you can use your stylus. Miracast depends on Rom kernel development. Due the fact that this is included in Stock Samsung Kernel Source maybe not working...
That is a problem of all Samsung devices, lack of Source code...
Ok. Allshare Cast is Samsung feature but AOSP based roms do have Miracast support , correct ?

That's not necessarily true.
Some custom ROM's based on Samsung stock break things that work on the official ROM by using a different kernel, modifying the framework or implementing alternate versions of Samsung components from other devices. You need to check the OP and read through the thread to determine if any stock features are broken or missing.
It is definitely harder to mimic all the features of the stock TouchWiz firmware on ROM's compiled from AOSP source. If you plan to use one of those ROM's you really need to verify that the features you use/need are available and can expect to add several third party apps to get anything close to stock sPen support.
Here's a similar thread from last October and this post should help with fleshing out Spen support for AOSP ROM's even though it was written for the Note 3.

Allshare Cast is just Samsung's name for Miracast but it is still certified by the WiFi Alliance so it should be compatible. From the Wikipedia article on Miracast:
On 29 October 2012, Google announced that Android version 4.2 (updated version of Jelly Bean) will support the Miracast wireless display standard, and by default will have integrated features for it.[8] As of January 8, 2013, the LG Nexus 4 and Sony's Xperia Z, ZL, T and V officially support the function,[9][10] as does HTC One, Motorola in their Droid Maxx & Ultra flagships, and Samsung in its Galaxy S III and Galaxy Note II under the moniker AllShare Cast. The Galaxy S4 uses Samsung Link for its implementation.[11] In October 2013, BlackBerry released its 10.2.1 update to the existing line of BlackBerry 10 devices, which brings Miracast and Wi-Fi Direct support to the Z30,Z10,Q10 and Q5 models.

Chromecast screen casting is different and obviously requires a Chromecast device. I have done both successfully on the stock ROM and the latest versions from @civato but don't expect either to work on AOSP based ROM's at this point. They do work with the M10 snapshot for CM11 on my Nexus 4 but the Note 8.0 is not a Nexus device and I think those functions are highly dependent on the kernel used.
If you want all the features of the Note 8.0 working then you should stay with something close to the stock ROM. It will take a lot of time, effort and some money for apps just to get away from TouchWiz interface.

paying for 3rd party apps is not an issue if there are apps supporting S-pen.
I would stick with Samsung ROM if I believed Samsung will support this device anymore. But I doubt Samsung will release Android L to it.
So , I should turn to non-Touchwiz rom at some point. (I like the idea of 8 inch note device, and Samsung doesn't release a 2014 edition replacement)
2 things important for me on the Note device:
- S-Pen usability with 3rd party apps (I understand that non-Samsung roms support S-Pen)
- Screen mirroring (miracast should work if the rom is based on AOSP)
Any advice for a good non-Touchwiz rom ?

"Should" and "does" are two different things.
Out of curiosity, I loaded the M10 snapshot (the latest) for CM11, just to see if it supports screen casting for Miracast and/or Chromecast. The answer is "no" and it doesn't even appear in the display options for settings even though the M10 release for my Nexus 4 works fine with both.
The moral of the story is don't expect much better support in the future from the AOSP ROM makers. CyanogenMod will probably release an L (CM12) version since the N51xx is an officially supported device but don't expect it to support all the features of the Note 8.0 that the stock ROM does.
For a ROM recommendation, I'm planning to stay with the enhanced stock versions from @civato.

I appreciate your confusion on the stylus support, so let's talk about that. First off, the stylus is not unique to Samsung. Most if not all ROMs will provide the status of the raw stylus data (location, pressure, button, storage slot) to applications. Programs written to access the stylus at this level should work on any device that has the (Wacom?) stylus, Samsung or not. The PS Touch in the store should work fine on AOSP - the one I tested last night was a freebie tied to the Samsung ROM and didn't work on Omni-ROM (no surprise there). The fly in the ointment is that Samsung includes a library of stylus functions in their ROM which makes it easier to develop apps for use with a stylus, and which will lock the apps to Samsung devices (the APIs are Samsung-specific). Any app using those APIs will not work on AOSP ROMs. It is easy to tell the difference in the Store because those apps will be for Samsung-only; if it works on non-Samsung devices it is a good bet it will work with open ROMs.
In addition to the stylus software library, Samsung includes software to do things when the stylus is removed from storage or touches hot-spots, a keyboard option to use the stylus and handwriting recognition to create text input in any program, and stylus-enabled programs like S-note that can also convert your scribblings to text with varying levels of success - YMMV. These functions can all be added back into AOSP ROMs with programs from the store, at a modest price. Of course they will be a little different but the functionality will be there.
My recommendation would be to go with Civato's latest ROM (FlexBurst) for now, assuming you are using your stylus a lot and enjoy the Samsung implementation. Civato has added into the ROM support for aircommand, which is available on other Samsung devices but not stock for the Note 8. Also, there are newer versions of S-note available. Samsung (and thus FlexBurst) is currently at 4.4.2, while Omni-ROM is at 4.4.4; I don't see the small lag as anything important at this stage. Once Samsung stops supporting it there will be time to convert to AOSP. In any event once your Note is rooted and TWRP Recovery installed it is a simple matter to make a Nandroid and Titanium backup before installing a new ROM to try out; if you don't like it then wipe and reinstall - not a big deal. The only downside is that you will break your warranty if you have a KitKat bootloader (required for Civato's latest as well as Samsung's latest).
Hope this helps,
Greg

SM-P600 S-Pen and Lollipop question

Are there any of the Lollipop builds in which the S-Pen has functionality other than being just a regular stylus or pointing device?
First of all, the only function of the SPen is to work as a stylus(Active digitizer). Everything else is a rom feature/functionality implemented by an app, not the pen.
Answering your question; sadly, not completely:
- Even the acclaimed rayman cyangenmod cm12.1 still lacks pen functionalities as it doesn't recognizes the eraser on more professional wacom pens(even from Samsung ones dedicated to our tablet specifically).
- Temask Rom is doing a very good work adding some personalization to the possible pen gestures and behaviors but nothing as far as creating an stylus experience as Samsung does with all the apps Samsung brings to the table.
- As far as i know, only touchwiz based roms have those stylus dedicated apps you are searching for as part of the rom.
The thing is, installing Roms such as CM or Temask CM is done to get rid of the Samsung Touchwiz environment with all its gimicks and features. People that flash this kind of roms are searching for, at least for now, a nexus tablet that has a digitizer to draw/sketch. I get that some Samsung features are useful, but many of us think that the lot of them makes the device lagy and only a low percentage are worth it.
This said, there are only two options, your feature needs are covered by third party apps, which are very rare, or you have to stay with touchwiz based roms.
To give you a list of the third party apps that are available visit this thread:
http://forum.xda-developers.com/showthread.php?t=2641400
Check if they cover your needs to see if changing roms is worth it for you. :good:
What we can hope for the feature:
If we can get an app on cyanogenmod source to add better API for the stylus(Attach/Detach Gestures, On/Off Digitizer, Hover+ButtonClick, Double Tap, Tap/Button Click, etc) developers would be able to make marvels out of it and make apps that compare and surpass Samsung implementation for features(Quicker, personalized and not making the device laggy); most importantly making it universal for any rom based on CM(Which are a lot). Currently we have CM SPen Addon: the downsides: you have to pay to get all the features and if you make an app out of it, the user would have to download 2 apps or more to make it work.
There is also a great project here in xda, beta status, that is trying to add some functionalities such as the action menu and screenshot noting. I dont know how it is going because i am not a beta tester of it but looks promising. The downside again, even if they do it incredibly well; the project doesn't add anything to the table for a "universal" API so it is not going to make more apps "pop up" for the device, you are stuck relying on them for more solutions. If anyone had the link, please post it.
I hope I took into perspective what non Touchwiz roms are at the moment, what they are going to be in the near future and what they can be if things play well. :good:
Thanks for all of the information. Definitely something to think about. The feature of the touchwiz roms that I use is the s-pen functionality. The rest of it I don't care for and I freeze as much as I can.

Yep, that i why i use cm. I would barely use touchwiz features and they would lag a lot when i did so i stopped using them. I changed to cm and i have never looked back. The only thing is that GPU is not optimized optimized at the moment so some things show graphical glitches and stuff. Don't know i that is going to get fixed soon, or ever for that matter. I use this tablet as a netflix-notebook machine and it works just fine.

There is also LiquidSmooth. It has the same S-Pen features as temasek ROM but it is based on Slim ROM which is very battery efficient. Only feature I miss from TW is multi window, but this is made better by the stylus gestures.

So pen presure sensitivity is not implied in such custom ROMS as it is in Touchwiz?
Pen accurate location detección on and over screen, tilt sensitivity and preassure sensitivity ranging from 1 to 0 are hardware-driver based. If the ROM got the drivers and your machine has the digitizer functioning correctly, it is going to work as well as it is intended to. Furthermore, your ROM could or could not implement OS-wide functions to make a better and seamless experience for you and complementing apps. And last but not least, your ROM(like touchwiz) could add unique apps to give a better or worse experience.
TL;DR: You can have a working spen without touchwiz.

Samsung-specific features vs. AOSP/Custom ROM

Hello everyone,
I recently bought a Tab S 8.4 and I do have it rooted along with a custom recovery but I'm still running the stock Lollipop Samsung ROM with Touchwiz. Here is my question: If I were to flash a non-Samsung ROM like IronROM or CM12 or anything based on AOSP, what are the Samsung features I would be losing?
Here's what I can tell so far:
Fingerprint Reader
Multi-Window
Touchwiz Overlay
Hancom Office Software
S-Voice? Unsure
Peel Smart Remote? Unsure
Toolbox
Quick Connect
Will I lose Power Saving and Ultra Saving Modes? Unsure
Guest mode/Private mode
Knox? Unsure what this does
Thank you.
Bumping this in case anyone has any insight they could share with me, thank you.
IronROM is a Touchwiz 5.0.2 ROM, not AOSP. Since you have custom recovery isntalled, you should try flashing AOSP ROMs to experience the difference yourself. Perhaps you'll become a flashaholic like many of us :victory: . A Marshmallow ROM is available. I tried several TW and AOSP ROMs on various devices, and I decided I prefer TW.

Unfortunately, I now consider myself to be a reformed flashaholic I was hoping to avoid flashing several ROMs since it's a time-consuming process.
I did read up on some ROMs and might move over to IronROM since it keeps some of the Samsung features that might be useful. I'll end up deleting/freezing others that I don't want I suppose.
Thanks.
Personally, the only thing that keep me from using an AOSP Rom is Split Window, something that I use a lot.
You should consider if there is some TouchWiz feature that you can't live without, I consider most of it crapware.
Dont forget to run the Wanam LP Xposed module. It adds some customizations to TW.
Thanks all. I think multi-window and fingerprint reader are enough to keep me on the TouchWiz. I'll switch to IronRom and with Xposed that should do the trick, especially if I disable a lot of other Samsung bloat. Thanks again!
One major factor to me is that aosp does not support exfat. In this day and age and the size of media files that's a killer.
Also let's put something straight. TW like any other gui such as sense is just an enhanced interface.
It does provide many useful features. Samsungs problem is its insistence on bogging it down with unnecessary bloat, also knox should be optional.
TW can be just as efficient as aosp or cm.
On the tab A they included very little bloat and it runs very well.
The tab S has quite powerful hardware and should fly, which it does when all the chaff is removed.

Oh I had no idea about the lack of exfat support! That settles it then, I'm sticking with TW for sure and will switch to IronROM since it adds a few things and also enables the use of Xposed due to being deodexed etc. I can definitely disable the other bloat I don't need, in fact I have done that already on my current stock 5.0.2 ROM as well.
I am a serial Nexus user and the last 10 or so of my devices have all been Nexus, so TouchWiz is taking some getting used to. It does add some useful features and it's easy enough to get rid of what you don't want/need.
Thanks again everyone, much appreciated.

Cm13 does suport fingerprint sensor and multi Window (not 4 Windows, or mini Windows) but fingerprint isnt working right now.
Peel does work with aosp.
S voice is crap and Google search (even cortana beta) is far better.
Toolbox can be used by using an app called Toolbox (play store it, there are 5 i think)
So, you will only lose (and miss) ultra power saving Mode, because cm13 (even xposed modules have) has Its own saving Mode called doze
Knox is a security Mode to protect your info. (i never use it)
Guest/private Mode, are cm since cm12 and of course on cm 13 too
Soundcamp, the music workstation from Samsung, does not work on AOSP but is OK on IronRom.

Finger print will never work for this device on an AOSP ROM. The sensor is a proprietary Samsung device, they will not release the source code for it. Regardless of the native support for fingerprint sensors in MM, it is impossible to build support for the Samsung sensors into an AOSP ROM without the source code.

Custom ROM with close to stock S-Pen Suggestion

I've finally decided to root my Verizon Note 4. I've kept it on 5.0.1 to ensure I would be able to when I was comfortable there woulds be guides to help me though the entire process. I'm not new to rooting Android, but i haven't done so since my Note 2.
As I've had the phone for such a long time I'm very familiar and used to the note features. I'd like to know if anyone could suggestion a custom ROM that does not take away any of the S-Pen features or may even enhance them. Features like OCR in smart select are things I use all the time (reason why i didn't update to the note 5). Something that is light, fast, and stable. The GUI does not matter all that much as I can always grab a launcher, but if there ones with the newer versions of android that would be awesome. The main things I'd like intact are the S-Pen features and maybe S Note.
+1 did you ever figure out which rom is the best I would really want to go with or I'd rather would like an Oreo ROM 8.1+ with S pen function is this possible
