Any guidance on how I could debug why my T700 doesn't have the GPS working?

- Came from Malosasha's 7.0 ROM (descendent of Schischu's)

- TiBu backup of apps / data

- Rebooted to TWRP, reformatted data/cache to F2FS, flashed Lineage and 7.1 gapps nano

- Booted in, had some uSD card access issues, so reformatted uSD within Lineage and reloaded content from backup

- Restored apps from TiBu backup

Only issue I have is the GPS not working (Maps, Garmin Viago, GPS Status, nothing finds it. Location is ON, high-accuracy, not power saving.
[Galaxy Tab S Android Development] Paulicat:
I didn't adjust/set anything to get mine to work.

What I would suggest in your case, don't do the TiBu restore.

Just flash rom/gapps and don't restore, start as new and install GPS status.

I have heard of weirdness with TiBu backup on occasion but I am just guessing here.
[Galaxy Tab S Android Development] meduza:
.... how about the function to kill app by long pressing the back button? In my case it's not only killing the app but it lets the tab reboot :) Did someone maybe noticed that too? I'm asking carefully because I'm on a dirty install... . I'll never complain or call something a bug being on a dirty install, so I'm just asking.

[Galaxy Tab S Android Development] tebra:
It works!. Finally hardware buttons still disabled after tablet wake-up. Thank you
[Galaxy Tab S Android Development] physwizz:
I like to try things to see what happens. This is how I like to learn.

For example, I'm running 5 different ROMs on my tablet at the same time.
[Galaxy Tab S Android Development] koimr:
Just tried this, seems to work fine for me - app gets killed, there's an "App killed" toast, no reboot.

Dumb question but is it all apps or just some that cause this?

Ooops, just noticed you are using a T800 whereas I'm T700 so this might not be relevant at all to you. Sorry. :)
[Galaxy Tab S Android Development] steamrollerpark:
Long-press to kill foreground app works OK here.

Its in Developer Options
[Galaxy Tab S Android Development] chibot75:
How did you do this?
[Galaxy Tab S Android Development] meduza:
Thanks guys! So I know what I have to do (with next update probably).

[Galaxy Tab S Android Development] jimmys_:
Can someone please show me how to setup the battery profile to "Efficiency" (profile selection between Power Save & Balanced)? My T700 running this ROM only has 3 battery profile options - Power Save, Balanced & Performance selection. Thanks for any help/instructions you can point me to turn on the "Efficiency" option.
[Galaxy Tab S Android Development] C0derbear:
sadly, doing so did not help gps recepion work. ;^(

Did gps work for you in my Vanir builds?

Haven't tried them, I'll look it up but probably won't have time to implement until the weekend.

Is IR blaster working? It does not seem to be working with my SM-T800.
[Galaxy Tab S Android Development] physwizz:
I can't get the volume buttons to work properly.

I had to turn off "control ring tone volume" to get them to work.
[Galaxy Tab S Android Development] meduza:
Sometimes they work like they should, sometimes not. If they don't, I just change the volume by touching the volume bar on the screen. This works always.

[Galaxy Tab S Android Development] agdroubi:
If i formatted data and cache to f2fs, when I want to return to stock firmware will it work or I have to format data and cache to ext4 before?

You will have to reformat back.

The t700 doesn't need ring volume anyway.

[Galaxy Tab S Android Development] razholio:
could it be a modem version issue? I've got GPS working nearly as well as it did on official CM-12.1 (which was spectacularly well) and I just clean-flashed the 1/9 build with supersu-2.79 and stock gapps and nothing more. I say nearly as well because I used to routinely get >10 sats locked inside my house (!!) and now I'm 'only' getting 7-9 or so. It's still got a nice high signal/noise and a quick lock (<5s). I have not touched the baseband since I first got the tab running.. KK was it? I wiped it and installed CM12.1 immediately, so the baseband is rather old and might be a difference here.
[Galaxy Tab S Android Development] C0derbear:
The GPS was receiving on the previous N build I was using (https://xdaforums.com/galaxy-tab-s/development/rom-t3498956). I wanted to try this build to see if the performance/battery-life/driver-support was tangibly better (all are), the only thing I'm lacking on my T700 a.t.m. is the GPS, everything else I've tried works ... clearly this is a well tuned configuration in general.

I've a couple things to check, hopefully I'll have latitude this weekend ....

- Malosash's N build (7.0) that I *was* using

- Paulicat's MM build that he referred to earlier in this thread

- Worst case I'll consider putting on stock KK, but I'm not sure I want to - I know I don't want to use KK - if the only drawback is the GPS is not functioning for me, but it is for others, then I'll just not worry about it as my Tab isn't used for navigation much so it is a minor loss of convenience when compared to the better/cleaner experience with 7.1.
[Galaxy Tab S Android Development] chrisn812:
Not working for me either. This and mhl is what still keeps me going back to stock.

Anyone tested mhl?

Might be time to freshen up my dev machine from the SGHi747 days.

Just out of curiosity, if the T700 is a Wi-Fi only tablet, why is there a battery drain caused by mobile network signal?
[Galaxy Tab S Android Development] swazau:
looks like it aligns with the WiFi,so maybe its just showing WiFi as mobile data
[Galaxy Tab S Android Development] C0derbear:
gpsr update, restored to functioning under LineageOS 14.1 ...

- using twrp, wiped all filesystems and restored data/cache to ext4 (had been f2fs)

- flashed VanirAOSP, nano gapps, boot/setup, installed Gps Status; no gps

- wiped all filesystems, flashed Malosash'as last N-AOSP build, boot/setup, same setup/ result as VanirAOSP

- no interest in KK, so skipped restore to factory

- flashed again Lineage, nano gapps, boot/setup, installed Gps Status; no gps

- big shrug

- restored TiBu backup of everthing, set Nova prime as home as normal, rebooted

- gps now works, staring at gps status and sitting on my kitchen table (3 floor hous) getting 13 sats. and reporting DOP/HDOP/VDOP of 2.9/1.9/2.7.

?? Not looking at a gift horse' teeth though.

{shrug}

The only tangible change was the switch from F2FS but I fail to see how that could affect the gps receiver.

Great job to everyone involved with the building of this ROM! Keep up the great work! Best ROM for the T800 so far! :)
[Galaxy Tab S Android Development] physwizz:
Did you set your location to "device only"?
[Galaxy Tab S Android Development] C0derbear:
No, in all instances I have it set to High Accuracy.

Sometimes I've used that on my mobile phone because I use it "in the field" where there are no wifi to access.
[Galaxy Tab S Android Development] physwizz:
In that case it's using your WiFi to get your location and not using the GPS in the device.

If the GPS is working, "device only" should find your position.
[Galaxy Tab S Android Development] physwizz:
Has anyone been able to move apps to sdcard in this ROM?
[Galaxy Tab S Android Development] razholio:
Not if GPS status reports a GPS lock and shows that number of satellites locked on. Its operation is independent of the location type.

---------- Post added at 05:43 AM ---------- Previous post was at 05:43 AM ----------

I thought that functionality left Android with lollipop, no? You'd have to use adoptable storage with the sdcard used as internal rather than portable.
[Galaxy Tab S Android Development] physwizz:
True. I was too impatient. It takes much longer using "device only" to find the GPS coordinates. I wasn't looking at satellites. I just ran a test. It took almost a minute to find 20 satellites using "device only" but "high" was almost instantaneous.

I have 5 ROMs on my device and I can reboot from one to another. I only just recently found 2 non lollipop ROMs that I could flash as secondaries.

I can save internal storage space on the LP ROMs using link2sd or moving them to SD card. Can't do this with non LP ROMs yet.
[Galaxy Tab S Android Development] onlysky:
Nice work!!. It's possible to activate the root mode?
[Galaxy Tab S Android Development] physwizz:
Yes just flash SuperSU 2.79
[Galaxy Tab S Android Development] meduza:
Yeah, in future no more stupid CM root :)

“ We will NOT be shipping root baked into the ROM.

Root will be a downloadable zip based install similar to gapps installation (only need to flash it once).“

That's what I always did with CM anyway, flashing chainfire`s supersu :)

Mine's working too but it takes a while to start.
[Galaxy Tab S Android Development] C0derbear:
I like this version more than Malosash's 7.0 at this time, runs better, better video, less quirks, more recent base OS.

I haven't tracked things closely yet but I HAVE noticed that this rom keeps the cpu much lower on the Mhz overall, and more regularly/quickly drops down. For example, often being at 600 mhz when I'm doing low demand activity, where Malosasha's rarely dropped below 800 Mhz.

This rom is also clearly better on battery consumption, at least with default cpu governance and so forth.

You may want to explore with the cpu governor settings to bring this os up more in base speed, and possibly check that they're using the same governor, before doing a hard assessment of performance.

The kernels are, IIRC, different also, so there's a lot going on that varies between the two.

One of my base video tests is the "4K Beauty of Nature" video

https://www.youtube.com/watch?v=0wCC3aLXdOw

I have a local copy on SD, which I try first - doesn't play reliably on Malosasha's 7.0 build from local media, waste of effort to try over YouTube.

Plays fine locally on this ROM (first 15 minutes anyway), and appears (same first 15 minutes) to play back fine (ok, minor 'net congestion artifacts but both me and wife were using the network) at '1440' (manually setting to that instead of the default '1080') over my home wifi (2.4 Ghz, 12Mb DSL net service).

Local video playback initiated via 'Gallery'; using YouTube app for online and the using the settings within the app to change from 1080 to 1440.

Is there a way to boost max volume with this rom? I've tried mixer_paths.xml but no luck.

Btw. you can do Power + volume down to force reboot, then quickly switch to Power + volume up + home to get into TWRP.
[Galaxy Tab S Android Development] chibot75:
Yep, I did that and reinstalled. Worked the second time
[Galaxy Tab S Android Development] rloebrloeb:
How long before it booted up? I tried a second time and still no luck after 5 minutes. I'm restoring to stock now.
[Galaxy Tab S Android Development] chibot75:
Only a couple of minutes
[Galaxy Tab S Android Development] rloebrloeb:
I used TWRP to do a standard wipe, then reformatted data/cache to F2FS before flashing. This is coming from stock except for a supersu flash. Did I miss a step?
[Galaxy Tab S Android Development] chibot75:
I didn't reformat. Read there wasn't much of a difference. Maybe reformat again to ext4 and see if it installs?
[Galaxy Tab S Android Development] kaodd:
supersu have probs with f2fs
[Galaxy Tab S Android Development] rloebrloeb:
To clarify, I'm not trying to flash supersu on to this rom (yet), rather my previous condition was stock + supersu.

Do you think that the previous installation of supersu is causing a problem flashing this new rom?

I'll try again soon.

Very nice ROM been using a few days. Clean flashed a t800 and have these issues which are all pretty minor: SEANDROID message on boot, 5 ghz wifi SSIDs not displayed to connect to, volume keys don't work with control ringtone volume on, settings crash message on boot. Thanks again.

The one big issue that I don't think is related to this ROM is that Titanium Pro hangs on about 1 of every 4 apps I try and restore. I think it is time to find a better backup/restore app, any suggestions?
[Galaxy Tab S Android Development] amateurhack:
After having all the video issues seeming to be working or at least manageable under the initial release of this ROM, tonight I'm having problems in apps such as the History Channel (video stops with error message "could not load" after a few seconds,) and Syfy Now crashes when changing orientation and the video zooms in on the top left corner repeatedly. Where before I could get it to zoom out and stay, now it zooms back in after a few seconds.

I also ran into an issue where I can't access /data with the included file manager program. I thought I had full access before, but now I'm not even getting a notification from SuperSU for root request.

And, as I was hunting down an issue, I also found that titanium doors not see that I have Dolphin Browser installed. I've been through every app on that list the times and don't see any entry related to mobi.mgeek or tunny browser, or dolphin.

You could flash SuperSU 2.79
[Galaxy Tab S Android Development] C0derbear:
FWIW, I've used both the built-in Root (without SuperSU installed), and SuperSU via recovery-flash (with built-in Root disabled), successfully with a couple root apps (TiBu included).

Currently running in the latter setup with SuperSU 2.79, no apparent issues. Disclaimer: Haven' tried setting up fingerprint detection as this particular device (T700/Wifi only) is used primarily for media consumption and has the Samsung 'book cover' and I like it to open and be usable by just flipping open the cover.

I am new in to custom roms. Will there be a final version of this rom for T700 ?? Or if i install a rom, will it be able to get updates via ota? Thanks in advance...
[Galaxy Tab S Android Development] rloebrloeb:
Been trying to install this ROM, don't mean to hijack the thread for more general t800 issue, but I can't seem to flash any ROM...

I get stuck at the "Samsung Galaxy Tab S" screen on reboot.

I've just been doing the TWRP "quick wipe" option, then installing the image from .zip.

When I restore my nandroid backup everything works fine.
[Galaxy Tab S Android Development] C0derbear:
I'd think the plan that at some point the rom would be declared 'stable' vs the current 'development' status.

Whether OTA are at that point wired up I can't say, you may want to peruse the Lineage OS web site ( http://lineageos.org/ ) for more info. Note that the build for the SM-T70x/T80x isn't AFIAK 'official' so there may not be device specific info on the web site specific to our devices. {shrug}
[Galaxy Tab S Android Development] evo_tr:
So first, this rom is kind of a beta version yet and secondly it is not actually optimized for galaxy tab s series. So my question is; is it logical to use an unoffical custom rom? Will there be any benefits for my tablet and security of privacy?
[Galaxy Tab S Android Development] chibot75:
I don't know whether it's logical to use this but what you'll see is better performance (In my view) and more customisation.
[Galaxy Tab S Android Development] C0derbear:
The immediate benefits are

- using more recent Android OS (7.1.1) than available OEM (6.0.1), and taking advantage of features therein

- supporting development community for working with LineageOS to provide quality alternative to OEM

- ability to use root-requiring applications

Security level may or may not be better, in some ways it's better for sure (newer kernel, less vulns) but update rate for "monthly security updates" is not guaranteed.

The immediate drawbacks are

- SELinux is in 'permissive' and not 'enforcing' state, so not necessarily as secure vs some issues

- ability to use root-requiring applications (yes, also a drawback!)

- requires use of tools to implement (ODIN, custom recovery), by end user, which if mis-used or there is A Problem may result in "hard-bricking" of the device

The choice is yours, in the end.
[Galaxy Tab S Android Development] zigonneux:
As C0derbear said and :

1: it's totally illogical but it's a lot of fun. :D

2: The monthly security update are always there... and updated.

3: These test roms are for playing and having fun testing new stuff, not for Banking and buy some stocks on line.

4: The security update on the MM stock Rom date April 1st on my Tab s T-800 and January 1st on this Rom.

5: If you need a secure Rom and don't really know how to get out of a bootloop caused by flashing Supersu, for example, you might want to avoid playing this game.

6:There are many tricks to get out of a bootloop but when it happen and you don't know how to fix it, it can be a nightmare.

7: Learning all those tricks mean that you have some chances of bricking your device , as C0derbear said. So far only 1 coder has bricked his device but I've been scared more than once wondering how to fix my device.

8: you don't have to root your device if you want more security, but there is an option to get a prompt before according root to an app.

9: We should get some OTA updates once the lineage website and organisation is all done.

10: One more thing: this Rom is totally Beta 1 so you can't restore your apps from the goggle play store automatically. It might be a lot of work to do all the settings again.

The best way for those who are not used to flashing buggy roms is to read the thread and wait until the ROM is stable enough to use it. In my view, the one who has more chance of bricking his device is the Coder who try the Rom before posting it... as it did happened to Nvertigo67.

My 2 cents.
[Galaxy Tab S Android Development] evo_tr:
I now understand that it is not for daily use yet. Its nice to know that i can customize my device and even get more performance but stability and security is my priority. Maybe i'll have a look later if comes a stable version. Thank you for all the answers anyway.
[Galaxy Tab S Android Development] pnomandk:
Just installed here on a SM-T800: Wipe data/cache, flash Lineage and gapps as well as SuperSU (without changing away from ext4). I Got the two red lines while flashing, but apart from that, it went well and booted correctly (with a quick automatic reboot due to SuperSU).

There's a few quirks (like if you group several items in the launcher, it opens centered instead of at the original position), but overall it runs smooth.

GPS is not working for me, though. Might be a misconfiguration somehow; logcat says 'CANNOT LINK EXECUTABLE "/system/bin/gpsd": library libsec-ril.so not found" so I guess a library is missing somehow or gpsd is somehow not linkable for other reasons?

Let me know if I can help to debug this.
