I have also problems with my external SD card. In the options of the Here WeGo navigation app the external SD card is not shown at all for storing offline maps. In contrast, in Google maps the SD card is shown and can be selected but if I try to store offline maps on the SD card the download never finishes so it seems that there are problems with the writing access to the SD card. I installed lineageOS version 2017/03/16 and everything works fine. Unfortunately, I cannot install version 2017/03/30 (which seems to be the last working version with correct SD card access) since this version is no longer available on the lineageOS download page.

Dear [MENTION=1255089]LaCruz[/MENTION] and [MENTION=4222965]deadman96385[/MENTION],

Maybe you can take a look at the problems with SD write access? This would be great! :)

Additionally...

I noticed (maybe others too) the lockscreen don't rotate.

If you add the following lines to the build.prop you can easily fix this.

log.tag.launcher_force_rotate=VERBOSE
lockscreen.rot_override=true

I have a problem setting up the tab after installing the official.

It installs nicely. But fails when setting up, it claims I don't have a network connection if I choose the option to backup from the cloud. If I try to set up as new, the setup wizard keeps stopping.

Have made a clean install of both 2017-05-25 and 2017-05-18. open gapps arm. 7.1 nano

https://download.lineageos.org/n2awifi

Installing latest unofficial 2017-05-25 works.

Any suggestions what I might do wrong on the official.

Thank you in advance.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] nachordez:
I can't say for other people. For me, just that I have lots os configurations, apps and so that takes a day to settle again as it's now. And to change into official needs a clean install. So, by now, I'm in Unofficial. Let's see if there comes the time I can have a couple of days (my life is absolutely stressful right now...)

Sorry, what issue are you talking about?

I have a SM-T520, the latest lineage-14.1-20170525-nightly-n2awifi-signed.zip installed and cannot confirm any problems when writing to the external microSD card.

At least, I always download a new LOS build to /sdcard/Download, then move it to the external microSD, then reboot to recovery and update.

No problems so far.

What should I do to see this issue?
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] nachordez:
The problem is not accessing the SDcard trough a file manager. No problem with that.

The problem is that common apps don't are able to see or to write to SDcard their downloaded data (Netflix, Spotify, GPS applications...).

And internal memory is limited...

So, that's what this is the most worrying problem right now.

If you like to test it by yourself:

Google Maps (save offlinemaps to ext. SD),

Dolphin Browser (save downloads to ext. SD)

FolderMount (root) (swaping Files to ext. SD)

Netflix (save movies to ext. SD)

and a lots more ...

These apps full working with nightlys (official and unofficial) until March 2017.

Arround that date there were changes to sd-permissions in official changelog.

Meanwhile last working official nightly isn't no longer available. :(
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] bbsc:
Thanks for the explanation.

I use quite few such applications and could have it missed.

But Poweramp, at least, plays tracks from ext_sd fine :)

I'll double check everything.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] Richard60:
The builds later then 3003 have a problem with external SDcard. With navigation apps you cannot save maps on external SDcard. And you cannot save Netflix downloads on external SDcard. Also you cannot move apps tot external SDcard.

Just installed lineage-14.1-20170601 Nightly. I adopted my 64GB Sandisk Ultra as internal storage (working fine), so can't comment on the external storage issues others are seeing.

So far, this ROM seems rock solid and MUCH smoother than the stock KitKat Samsung ROM. Even after re-installing all of my apps. I'm very impressed. RAM usage is roughly half what it was before. Scrolling, web browsing, transitions, etc are all smoother and faster with this ROM.

I bought an iPad Air for my wife and this SM-T520 for myself a couple years ago. They were priced competitively. Her experience has been smooth, with good support and regular updates. Her tablet still runs fine. For my part, I just felt like Samsung took my money and just wanted me to then F@#$K Off. The tablet had been a real disappointment, and I'd promised never to buy from Samsung again. This ROM has really helped :) I still think the folks at Samsung are jerks for abandoning their customers like this, but at least the tablet is now living up to it's potential :)

[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] moloko01:
Thats not realy true. The LOS filemanager has permission, other Filemanagers not. Files/directories extSD will be shown as 0-files with no permissions. Don't know, this has no high priority for devs?? This all still works untill nigtlies 3003.

If this is hopefully fixed, it will be the best rom for our devices, ever. Thank you devs.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] nachordez:
Other file managers I've tried see and write the extSD properly, and some apps like TitaniumBackup do work properly also. But many other apps (most, and some of them very well known and used apps) don't, and that's the main point, and can't also be moved to extSD, which would be very useful with limited internal memory as this device has.

I'm not so convinced to use the SD as adopted storage, which could be a nice way of helping this lack of space. I use a lot os space in my SDCard for carrying big documents (musical scores and so) while travelling, and is much comfortable to extract the sdcard, copy/substitute complete directories of several GB and take the card again in the TAB. So, adopted is not so good a solution for me.

And I hope that I should not be too difficult to find and solve that problem (knowing when it did started, so, perhaps the failing submit could be identified and corrected). But I'm not dev, as [MENTION=1255089]LaCruz[/MENTION], so, perhaps is very easy to say, but not so much to really find it and fix it.

I'm still confident on the great work of our devs and the solving of that problem, the only important (at least that iI have found) in this wonderful development.

thanks!

Sorry, did you try to access for example extsd/android/data with a file manager like well known 'cm filemanager' from play store. Since nightly 3003 this don't works anymore. Many apps uses this path to write add information to extsd/android/data or obb. Mybe it is diffrent to do with or wothout rooted device?
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] nachordez:
I can see this folder with different explorers I have (I usually use MIXplorer, from here in XDA). Some offer directly an access to the sdcard (usually named by its id-number, mine for example something like 9607-5376).

The route names to sdcard have changed in N (and MM if I don't mistake). That can be a problem added. And could that have something to do with the apps? Could system be not giving permission in proper routes? [MENTION=1255089]LaCruz[/MENTION], what do you think?

I'm rooted, BTW, but there was someone who said that he could use the SD in apps if not rooted (not my case, I've tried).

The route I have to use in MIXplorer to access the sdcard, BTW, is not

/extSdcard or nothing the like, but /storage/xxxx-xxxx (ID of the card) but that should not be a problem on MM organ with a proper Storage Provider. And in Titanium backup, for example, the storage provider works fine. But it's a root app (I'm on magisk, with hide root for everything but just really root apps, like TB, explorer...)

Don't know it any of this helps...

The other route to extSd is

/mnt/media_rw/xxxx-xxxx

An the previously said

/storage/xxxx-xxxx

There's no other shortcut automatically generated by OS, though I think that's the expected in N. Ain't it?

OK well thought I would share some experiences with this ROM.

1. Have been dirty flashing updates but have decided to keep it clean and backup, install with clean data partition then restore. Main reason being when I play CoC I get freezes during game play and I suspect that maybe due to Deathly Aduitor not being kosher with a dirty install. If I am on a clean build then all is well.

2. I have two users on the tablet and have found Google backup/restore unreliable and incomplete . So currently gonna do app + data backups using Titanium and have changed to Nova launcher as it has a backup option. From what I can see Trebuchet does not have an option to backup. I have yet to test the restore so will see how it goes. There seems to be no easy option to backup second users on the tablet including with titanium. However I did get a Nova backup so will see how that works on restore.

3. The lineage changelog makes for some deep reading. Frankly the ROM is working really well for me and all I need to know is when a release has occurred that includes the latest security patches from google. Other then asking on this forum, is there any other way of knowing?

Open to suggestions and help. Thanks in advance!

Rooting and flashing

Hi All,

It has been a while since I have been on xda and attempted any rom flashing. Just purchased a second-hand galaxy tab pro 10.1 and would like to get the latest Android on to it.

I am getting confused between superSU and TWRP for rooting and flashing.

Is there a step by step guide anywhere both for rooting the tablet and then flashing the ROM?

There are lots online but I am not sure what the latest and best method is?

Thanks,

Tax
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] daryah191237:
Hi tax

Been doing this for awhile so will give you basic outline. Google best friend for more details.

1. Get TWRP custom recovery installed. This needs to be flashed and traditionally people used ODIN.on a PC tethered to your tab. I used an app called KingoRoot for this tab which I found on the Web to straightforwardly get root access. Then an app called Flashify to flash TWRP.

2.Boot into TWRP and take backups of the existing ROM if you want. Lineage is really good so I wouldn't bother. Flash the latest build of Lineage and GAPP from. TWRP

3. This unofficial Lineage build has something called Deathly Aduitor which does performance tweaking. It needs to have root to work. So definitely flash supersu at install and every future clean install.

4. I wouldn't risk dirt installing new builds of lineage. See post above

Good luck

Don't use the camera at all. I suspect though you may be dirty flashing. Does it crash after a clean install?

Hi Daryah,

Thanks for this, helpful. I am still confused as to whether superSU does the rooting or TWRP because you mentioned installing SuperSU at the end, I thought I needed this first to root? Have also been looking online but i think at some point another method was released as I see some guides talking about SuperSU and others about TWRP.

Thanks,

Connected, No Internet

ROM has been working wonderfully. Really enjoy the speed, smoothness. Feels like a new tablet.

Yesterday, though, I found that, while I am connected to my WiFi network, I've got a little "x" in the lower right of the WiFi icon on the tab, and it's listed as "Connected, No Internet".

All the other devices in my house connect w/o issue, and the tab can connect to other WiFi APs w/o problems.

I've tried restarting the tab, restarting the router and APs (Unifi UAC-AC-Lites, two of them), resetting the clock on the tab, forgetting and signing back into the network, etc. Oddly, I can connect to other devices in the house (Linux file server, web server, Unifi controller, etc), but nothing outside the house.

Any idea what's going on?

Thanks again for a wonderful ROM!

Update: Moving this wireless network to static IP fixed the issue. This was found searching various Samsung forums. Would still like to know what is going on :)

I installed latest twrp 3.1.1-0, latest official linageos nightly (20170608) and opengapps nano (open_gapps-arm-7.1-nano-20170609). While opengapps is being flashed, the tablet always reboots. I found a similar thing here, where it is attributed to memory getting full: https://github.com/opengapps/opengapps/issues/56 . I am surprised other people are not complaing about this issue here. Are people using another version of twrp here?

Having issues with 0608 nightly build

This is my first time flashing a lineage rom, and I think I've come pretty close to getting things working .. BUT:

I flashed the Lineage nightly build from 08June, Gapps, and addonsu-arm.zip. (I didnt see an "official" version of lineage OS on their site, just nightly builds. Is there a link I'm missing? )

1) When I connect my tablet to the computer, windows explorer shows the tablet, but neither the internal memory nor the SD card are visible. Updates: This morning both internal and external cards are visible in Windows Explorer. And this evening, that has stopped

2) I click on the "Files" app on the tablet and it closes disappears. Update: This morning Files app seemed to be working, but this evening, it has stopped

3) Other file explorer programs do not show anything in internal memory and File Commander shows neither the internal memory nor the SD card. Update: File commander and other file manager apps saw both cards in the morning, but that has stopped again

4) Lock screen rotation does not work at all

5) I dont have root. Update I DO have root. Found the setting in developer options to enable root.

6) The only way to get files onto or off my tablet is to remove the SD card and load it onto my computer. I tried this with the Resurrection remix ROM but TWRP was unable to flash that zip file even after I wiped the lineage install. Update: This morning, windows sees the drives on the tablet, I can copy and paste files there at will. But that function stopped this evening

7) when I open chrome to download a file, i get an error message that the SD card is not available. ]Update: Resolved today but no longer working this evening

8) I used the "update" function to download an update to the OS. When i went to install it, I got a message that the install required rebooting into recovery. I clicked proceed but got a message that the tablet could not reboot into recovery.

This morning, pretty much everything was working. I opened the camera app this afternoon and that crashed the tablet. After I rebooted, the problems I had last night are back.

outside of these issues, the tablet is working for what I need from it. I can watch netflix, read books, play a few games. etc.

Any suggestions?? Any idea of what changed? Thanks
