Alright thank your for your research, i will try this step later.

The battery performance is okay but i noticed a difference from before and now so... anyways there are much more important things in this world ;)
[Shield Tablet Android Development] billxda5:
What's the usual SOT of this tablet? I usually only get 3-4 hours and it's not on full load, just browsing and youtube. Would installing stock lollipop 5.1.1 improve my battery life significantly? I've read so many forums already and they say nvidia screwed up with marshmallow and nougat in terms of battery. I need battery life.
[Shield Tablet Android Development] Steel01:
It seems to depend on model, unfortunately. My original tablet(s) was the LTE model wx_na_do. I was getting maybe that 3-4 hours out of it. Even with the screen off, it'd go from full to mostly dead overnight. Then I got a couple of the newer wifi only models, sb_na_wf. On the exact same builds it lasts days with the screen off. Left one laying around for 9 days and still had over 90% battery. Screen on time for browsing, ssh, etc, I'm getting 6+ hours, but I don't have an exact number. Probably closer to 8-9.
[Shield Tablet Android Development] billxda5:
Damn, it might be a lottery. I got a wifi only k1. Should I change the battery? It's been like this ever since.
[Shield Tablet Android Development] Steel01:
Finally went and tracked down the camera issue where it wasn't working for non-hdr. I'll try to have that pushed up by the next official Lineage build. During internal discussion, it was brought to my attention that I shouldn't be shipping NvCamera. However, in the process, I got Snap working again. So, I'll be replacing both current cameras with snap. Asides from hdr, I believe all features are covered, plus some. If anyone really cares, I can make a flashable zip with NvCamera, but I don't think that's needed.

Hi [MENTION=1416222]Steel01[/MENTION],

My Shield K1 showing update notification, when finish update on recovery it stuck on lineage animation. Is it normal?
[Shield Tablet Android Development] Eddy74:
Hello,

The tablet only supports non-DFS channels from the US, so 36-48 and 149-165 is it possible to unblock the other channels? The wifi region codes do not work also on LOS.

Thanks.

[MENTION=1416222]Steel01[/MENTION] I have some lag when I charge my shieldtablet... Why? The touchscreen not works fine...

A weird thing happened on my tablet... the last update of 2017 broke my LTE, and this last update did not fix it. I wiped everything except my sdcard and flashed 5.0 firmware along with the lates update... the issue remains. The error I get is "No Sim" and removing/inserting the sim has no effect either. [MENTION=1416222]Steel01[/MENTION] do you have any suggestions?
[Shield Tablet Android Development] hör.ich.da.ein.mimimi?:
Yes, this is a known issue. You are not the only one and this is a hardware issue, it can't be solved from software. The touchscreen isn't recognizing your finger as it should, I think this is what you see as a "lag".
[Shield Tablet Android Development] Kaneki:
Hardware issue... Nice...

Thanks for answering [emoji1305]

I'll have to look at this tonight. Unfortunately, my dd isn't an LTE model anymore. I've got three of them, but all three have cracked screens and the one that has a semi working battery has a broken modem. So, to test LTE, I have to jump hoops now. However, nothing LTE related should have changed, so I expect the software should still work. But I'll test as soon as I can.
[Shield Tablet Android Development] Both Barrelz:
Lol. All 3. Dude, what do you do with them? I found my shield almost indestructible, possibly the most sturdy device I have owned.

[MENTION=1416222]Steel01[/MENTION] is it possible to get fix for hotspot?
[Shield Tablet Android Development] p3dboard:
Is anyone else got issues with Drm content playback? When trying to play movies or tv shows from Google play movies, or streaming from Netflix, i just get a black screen. I get audio, but no picture.

I tried aosp extended and drm playback is working fine, but not on lineageos.

I have a shield lte 32gb model.

Btw, mobile data is working for me, getting hspa connection, i only occasionally get lte depending on the mobile tower where i am - just reporting as someone se said they have issues with their lte connection.
[Shield Tablet Android Development] The_miah:
Anyone else see a jump in battery usage or could i just be having sudden battery death or other weird issue. I always put my tablet into airplane mode when I'm not using it & i'm now seeing tablet idle at the top of the breakdown chart when checking my battery usage & I thought that in the past my top usage was always the screen.

It's gotten so bad that just installing a smaller game from the playstore just dropped my battery % from 19% down to 14%. At that rate i'm kind of afraid to even try casual gaming on it, much less fire up Bluetooth for a controller & do some serious emulation.
[Shield Tablet Android Development] hectoralexgarcia:
Thanks for your input, I really don’t know what’s going on with my tablet. I swapped out the sim to another tablet and it worked fine.

I’m also having trouble casting to chrome cast and YouTube, but DRM on Hulu and Amazon work fine... except for casting.

I’m trying out Stock Optimized ROM but can’t get it to finish the setup... blob flashed and all. So I came back to Lineage because it will run. My tablet is a pyro LTE.
[Shield Tablet Android Development] p3dboard:
Are you on 5.3 blob? I am coming from Stock 5.3 on my 32gb lte model, as i wanted to see if lineageos or other custom roms didn't have the battery drain issue that stock 5.3 has.

But it's happening on all custom roms for me as well. I have a pyro tablet, so don't want to flash the full stock from nvidia via fastboot as i don't want to brick my device.

I am going to try flash the 5.2 blob file to see if that makes a difference. I thought the blob was just some basic boot files, but maybe it contains cpu micro code patches and other things that affect the cpu usage in any rom? Anyone know?
[Shield Tablet Android Development] The_miah:
Honestly i couldn't say since i went LOS the moment i bought my tablet locally & the PO also was running a custom rom as well. I can add that a new related issue has cropped up though. This is my 1st time fully charging it since the last update or 2 (simply because i've been too busy to play much) & currently it's sitting at 98% charged & "3 minutes left until fully charged".

it's been at that state for hrs now. I never had an issue with it refusing to fully charge to 100% before. Have i buggered it up somehow???
[Shield Tablet Android Development] fpozar:
Your battery probably got decalibrated in all the time you were using it, and now the tablet, thinking it's almost full, slowed down the charging. Nothing to worry about, let it sit there for some more until it is on 100%, after that the battery should be calibrated again
[Shield Tablet Android Development] mirhl:
Use drminfo to check your widevine version.
[Shield Tablet Android Development] Steel01:
DRM issues is probably still the live display problem. Disable live display in settings->display and it should work fine.

I still haven't had time to look at the LTE issue (read, I forgot over the weekend and worked on 15.1 instead). But given that someone else has it still working, I'm suspecting the modem may be going bad. One of my three LTE devices has a completely dead modem and another is intermittent. And all of them can get in a weird state where the modem has to be reset to see the sim card (nvidia literally has ril code to reset if the sim disappears). So, unfortunately it seem that the icera modems just aren't made well at all.

And what's this about a hotspot issue? Does it not show up at all? I honestly haven't ever tried, if I was hotspotting, I used my phone. And now my dd is a WiFi only model due to all LTE devices being various levels of broken.
[Shield Tablet Android Development] Luca-91:
[MENTION=1416222]Steel01[/MENTION] In the last 2 weekes I got 2 hard reset (I suspect Kernel Panics) just after I connected the charging cable to my tablet. Sadly I was in a hurry and haven't the time to dump a console_ramoops. Have this happened before to other users? Thanks
[Shield Tablet Android Development] steczko:
Hotspot used to work in prev. Android version. Now when i start thathering status Error is presented.

Unfortunately after last updated i also face a problem with "no SIM" :(
[Shield Tablet Android Development] Sh0X31:

[Shield Tablet Android Development] SolidSTI:
Can anyone comment on performance on things like Nvidia Gamestream and Moonlight when running stock vs LineageOS on the shield table?
[Shield Tablet Android Development] DanRub1995:
Zdraste, as gritsya, and when will Lineage 15.1 be ready? I know that everyone probably very much angry such questions, but still very interesting)

I tried opening a wifi hotspot on my K1 so I could hook up my phone and use it as remote for kodi but it didn't work. I can confirm this doesn't work on aex as well
[Shield Tablet Android Development] Naitsabes123:
Hey,

some month ago (September/November?) i read that there is a bug concerning adoptable storage. But since then i haven't read if this bug is fixed.

That is the reason my tablet is still stock…

I know ich should test it myself, but since the bootloader is still locked and the recovery is stock the backup would take some Mode time than just doing a nandroid backup.

So it would be really neat if anybody here could tell me if it works by now :)
[Shield Tablet Android Development] multiwirth:
Yes it works.

I´ve formated a 16gb micro sd in "mixed" mode and it seems to work like it should.

I have 4GB for internal storage and 10gb as removal storage.

Wifi only connects when there is no password set in the router options.

Hi,

I'm having issues connecting just to my home wifi. Connecting to other wifi networks is working and all other devices are connectin to our wifi network without trouble, there is just the Shield K1 that wont do it. I can enter the password and it says that it is saved, but it cannot connect somehow. The only set of configuration that worked was to set the router without password as security, which is no option in the city.

LineageOS version: 14.1

LineageOS Download url: https://download.lineageos.org/shieldtablet

Did you--

wipe: yes

restore with titanium backup: no

reboot after having the issue: yes

Hey, i was using version from 01.19, than after one week did ota update to 01.26. Not sure if I'm going crazy but my tablet seems to be getting hot agian when watching streams as when I was on stock nvidia 5.3.

Did anything change? I didn't notice any app draining battery in background or anything suspicious.

Are you guys using any custom kernels or maybe apps to limit cpu frequency?
[Shield Tablet Android Development] Bitcloud30:
Does any body here Play in this ROM ruls of survival? Does your screen respond when you play the app?

Or are there anybody who likes to try and report back if you have a responsive or unresponsive screen when playing the game, the app is around 600-700mb.
[Shield Tablet Android Development] yka1988:
[MENTION=4601805]Bitcloud30[/MENTION] Do you happen to charge and play at the sime time? Custom ROMs on the shield tablet have always had a laggy touch responsiveness when I was charging and using it at the same time. Even in simple tasks like browsing the web with chrome I could feel the touch responsiveness get worse.
[Shield Tablet Android Development] multiwirth:
Hotplug is broken due to an factory app that forces all cpu cores to be up.

Try to delete (rename) /vendor/app/NvCPLSvc so this app cannot start again.

---------- Post added at 09:11 PM ---------- Previous post was at 09:08 PM ----------

I have no issues while charging but if i use active speakers (which are powered by mains voltage (with transformator!) the touch gets unuseable.
[Shield Tablet Android Development] Bitcloud30:
No. Did u try to download and play the game? Am trying to look if its issue is on the ROM or the app itself.
[Shield Tablet Android Development] yka1988:
Nope don't have my tablet with my at the moment.
[Shield Tablet Android Development] acines:
I have tried it and during testing I was on battery. At start I can accept license agreement, but then game doesn't respond to touch. On my phone works normal.
[Shield Tablet Android Development] class459:
It also happen on my K1, I'm at 5.3 rom and 14.1-20180119 LOS
[Shield Tablet Android Development] Steel01:
Depending on how an app checks for touchscreen support, it could fail on all shield custom ROMs. Retroarch, kodi, asphalt games, etc all failed to work for a while. The first two fixed their checks and work fine now. Some of the less popular games seem to have not yet. Not much I can do about that, not without hacking around in the frameworks, which isn't going to happen.

Technical info: there's a java class that apps call to get input. One of the fields is a bitfield of supported input types. If the app just checks for that field being equal to the touchscreen value, it will fail if any other type of input is available. In the case of our tablet, stylus is that other available type. So, custom ROMs report both touch and stylus. If the app isn't doing a masked compare against touch, it'll fail to detect touch and will be unusable.
[Shield Tablet Android Development] robgee789:
Hey guys does this rom let me move apps or their data to the sd card becasue you cant on stock and the 16gb internal storage is a little bit small
[Shield Tablet Android Development] r0th Baby:
Same i also face the same issue cant touch the screen in game.. Idk but i will wait
[Shield Tablet Android Development] robgee789:
ill have to give this rom a miss until that is fixed
[Shield Tablet Android Development] primaleph:
I have this issue with the games Granny Smith and Bladeslinger. They only work on stock; on custom ROMs, they don't seem to get any touch input. The developers don't seem to care. One of them even offered me a refund instead of trying to fix it.

Since these games are originally for Tegra devices only, but work fine on my Essential Phone, I think the issue may be the way they check for a Tegra... It seems to work normally with stock software, but maybe custom ROMs don't respond to the check in the same way?
[Shield Tablet Android Development] marvi0:
Hello no problems on my side have a 128gb card and all apps are moved automatically to the sd card.

Not sure but I think I chose adoptable. The instructions are clear though they will detail what the different options mean.
[Shield Tablet Android Development] def1003:
Well i got over it since the answer is no, nice rom thanks for your work! battery life is improved!
[Shield Tablet Android Development] VJmac15:
Has the multitasking issue with this ROM been fixed yet, or is there a fix for it?

Or am I the only one with this issue?
[Shield Tablet Android Development] multiwirth:
Nope I have the same issue.

It kills apps in backround which shouldn´t be killed and does not stop heavier processes which ends in a memory leak.

I have the exact same issue with my HTC One Mini 2 running an unoffical build, wich behaves exactly like the the shieldtablet.

The big difference are those 2gb of ram which make the tablet useable even with this issue, the mini 2 is completely unuseable at this state and the developer confirmed the memory leak problem on my mini 2 (depends on baseband, hardware revision or firmware version what kind of issues this rom has on the htc one mini 2)
[Shield Tablet Android Development] VJmac15:
That is very unfortunate, for me that's a big Deal breaker.

Not really seeing any other Rom that can compare or is even as active as this thread ?.
[Shield Tablet Android Development] multiwirth:
But I think there is no fix for it yet.

You can try to use kernel adiutor but it didn´t help much in my case (you can edit the LMK with this app)
[Shield Tablet Android Development] VJmac15:
True, I've tried that.

Memory Locker.

Autokiller memory optimizer.

To no avail.
[Shield Tablet Android Development] alcopsy:
Use another kernel, your problem is "zram" it kill app backgrounds.
[Shield Tablet Android Development] VJmac15:
My device says Zram is disabled, in kernel auditor.

but ill try a different one. thanks for the recommendation.
[Shield Tablet Android Development] alcopsy:
We have tested with BitIO kernel, try it last
[Shield Tablet Android Development] HellGoNet:
Hi. I dont know if there is a better place for this question but I'll give it a go here. Otherwise please point me in the right direction.

I just got a new K1 after a rutine RMA. I decided to start over and leave my own modified stock rom behind in favor for LineageOS and the experience is very positive. have switched to Lineage on all my devices now. BUT there is some things i miss from the stock shield rom.

one of the things i really miss is the stylus buttons on the navbar. It is the very handy screenshot function first and for most i miss. It is just perfect, always accessible and straight forward. And I dont find any other apps for the purpose on the market as convenient

I've tried porting it myself but it seems to be more then just an app. I think it is in some way dependant on other things in the stock rom. I've tried as much as I'm able to but with my limited knowlage I can't get it to work. I didn't really expect it to, would have been to easy but at least I tried.

So I need help. It should be possible right? I mean isn't features like this just built on top of android. like moduls made out of a bunch of files. I don't know if something like this needs to be compiled into the kernel as well.

Any ideas?
[Shield Tablet Android Development] VJmac15:
Been testing with each Bito Kernel:

BitO-KU

BitO-K10

BitO-KX10

BitO-K11

I do indeed notice improvement, but end results are the same.

hey guys i just installed this rom and im getting real bad touch screen reponse some times, its not all the time and i cant seem to see a pattern to it, it just needs a really firm touch to register and it lasts a few minuets then its back to normal, has anyone else had this problem
[Shield Tablet Android Development] VJmac15:
With several tests I've had much better results!

I ended up using my SD Card for more memory with the app called "Roehsoft ram expander". My issue has gone away about 80%-90% of the time now.

My next step is to go into the settings and try to remove the apps I don't want killed by android by removing it from the optimization list.
[Shield Tablet Android Development] Luca-91:
Is root required in order to use Roehsoft ram expander? The play store description is written in german for me, so I can really understand.
[Shield Tablet Android Development] VJmac15:
Root is required. I believe an alternative app is swapper 2.

The recommended kernel auditor , low memory settings, lagged my device, lspeed profile set to performance fixed.

Dunno if these things conflict with one another but with hrs of tests, my problem is fixed to the point where I won't complain anymore.
[Shield Tablet Android Development] acines:
So I was experimenting a little bit with different LMK values and got decent results with following values. It's not a miracle, but a least you can listen to music while you browsing and maybe switch to FB. :)

Xiaomi Mi 5S Plus - natrium

Considering the new manifesto Lineage put out for compliance and features regardless of device, and the fact that getting Treble or Oreo on this is something that Nvidia themselves passed on, it may be a while.

Be prepared to wait patiently (Entirely aimed at those that harass the Dev when the "new-hotness" isn't out immediately). Nvidia has all but abandoned this to anything other than Security updates every few months (maybe)... In favor of the ShieldTV. At this rate, Lineage will be the only way to get updates both regularly and/or at all very soon.
[Shield Tablet Android Development] Steel01:
The one holdup for O on the shieldtablet is omx, hardware accelerated audio/video. Afaik, everything else works just fine. This is also a problem on flounder, the Nexus 9. So, I can't official ship until that is fixed. The weird part is that the omx libs I'm using work on foster. And they're the exact same libs I used for both on N. So... I'm confused why it doesn't work. But if anyone wants to run it anyways, there's a thread here with someone doing unofficial builds. I'm running personal builds on my daily driver with little problem at all. It's annoying that I can't play anything in youtube or netflix or such, but I'm actually not doing that much on my tablet anyways.

Anywho, tl;dr: There's a blocker bug and no known way to fix it yet.
