Thank you for bringing android 7 to this device. I installed it and it seems it's working fine except those know problems. But the most annoying thing is that I have to install older gapps (from november). Latest gapps don't work. Missing Play store app or something. Can this be fixed? This is also happening with cm13.
Thank you again for your work.

the worst problem w/ the cm 14.1 is no mobile data...but to each his/her own (unless one has a T280/just cares about wifi)

don't the gapps get updated anyway through playstore even if you start off with an older version?

Yeah it should. I haven't looked into why gapps is behaving that way. It also happens with my other CM devices like the Nexus 5. As for mobile data, I'll wait for lineage to be available before I get back to working on a Nougat build.

senior...is just age...doesn't mean anything more than that ha ha (at least that is my understanding...no I do not develop-though I tried unsuccessfully rooting this back in July last year-learned something about linux though at that time-lol)

now that is a thought..what are 99% of xda members doing on the boards, anyway if they aren't developing?

:laugh:

GPS not working, nor in CM13 and OMNI ROM it doesn't work that well :(

show some appreciation for the developer here-compare this to say the tab s and tab s2 (and they even have official android 6) where none of them have working mics, working calls, have data issues or have various issues (am talking now of cm13, omni and cm14 as a collective)...

there have been huge strides made here by the developer despite that just a few months there was no root and that this device has a semi-locked bootloader unlike the tab s/s2 for example.

Yes, cm14 is early and the OP says it is alpha and "As this is the first CM-14.1 release, I don't recommend you use this as a daily driver, but it should be good enough for some. Make sure you read the pending issues below and decide if this is acceptable to you before you flash this rom. This rom probably won't get much use out of some people until bluetooth is fixed."

so overall the developer has made lots of progress - give credit where credit is due and here it is due imo.

I was just adding on from what Kevinkuensken said, I am appreciative of the developer don't get me wrong, I have been playing around a fair bit and have found GPS works with the Extreme version of CM13 but I am unable to get a 3D Fix, just giving the developer some feedback or is that wrong of me ?

sorry my mistake-reading through app is always a hazard-lol-and seems like even a 7 inch screen is not big enough for me - ha ha sorry I apologize sincerely

Yeah GPS is weird. I am sure that GPS isn't working in the normal CM version as the lib itself fails to load. In the XTRM edition I've fixed it and it loads and can even detect satellites but somehow doesn't get a fix. I've read around and it also happens to AOSP based roms, I've traced it to a certificate issue with seems to prevent it from loading constellation data. Google maps seems to work fine though

yes Gmaps works off mobile data right? with the 2015-16 tab s2 getting offocial Nougat wonder why this device or any of the 2016 A series are not getting even Marshmallow? Strange are the ways Samsung works.

I didn't try it with Google maps, too fixated on the testing apps :( I guess I should have tried it out.

I believe Gmaps works off GPS and mobile data, it wont work if there is an issue with either of the 2, I have a tablet (Galaxy Tab 4) in my car as a dedicated media player/GPS/OBD device, I need to tether that to my mobile phone for Gmaps to work correctly, unless I'm doing something wrong lol

Agreed Samsung appears to only want to update their higher end devices and leave the lower end ones with what they shipped with, part of the reason I got this tablet is to replace the Galaxy Tab 4 which is stuck on 4.4 with NO custom ROM's, so I do have a lot of appreciation for jedld and all his work with this tablet ;)

    *** This project is now abandoned in favor of the LineageOS variant ***


    This is a port of Cyanogenmod 14.1 for the Samsung Galaxy Tab A 7.0 (2016) LTE SM-T285. Cyanogenmod needs no introduction, it is one of the most popular aftermarket ROM distributions around.

    5.1.1 is the best that you can get from samsung right now and it is not known if they plan to do any upgrades. I have absolutely no idea why samsung chose to stay with the outdated 5.1.1 mid 2016 when we already got 7.1 coming out. This custom rom is probably the best you can get if you want an upgrade from Lollipop. Performance on the latest build is also better, you be the judge.

    As this is the first CM-14.1 release, I don't recommend you use this as a daily driver, but it should be good enough for some. Make sure you read the pending issues below and decide if this is acceptable to you before you flash this rom. This rom probably won't get much use out of some people until bluetooth is fixed.

    Based off on Cyanogenmod 14.1 sources which is based on Nougat 7.1.

    Fixed GPS, Wifi Hotspot, Graphics issues, Calls, Camera,sdcard is now marked as adoptable.

    Works:

    - Wifi/SMS
    - Audio
    - Graphics with glitches (minor screen tearing, blank screen showing up on overlays)
    - GPS
    - Wifi Hotspot
    - Incoming/Outgoing Calls
    - MTP

    Bugs/Known Issues

    * Problems recording video

    Other Notes:

    - selinux permissive

    Most of the issues are fixable, I just need more time and encouragement :D

    SM-T280 Users: Unfortunately this rom would probably not work on it since the SM-T285 and SM-T280 have different kernels and slightly different hardware. I don't have access to this device so it would be hard for me to port it over. However I believe there are a lot of similiarities in the device tree that can be shared. If a dev with the SM-T280 is interested I can probably help.


    Download
    ========

    Remember flashing an unofficial ROM on your samsung device will probably void your warranty, Samsung representatives will probably not be able to help you as they are still stuck at 5.1.1 land as of now and have no idea how to handle a SM-T285 that is running 7.1.

    As always flash this at your own risk. Make sure you have a copy of the stock ROM so that you have something to fall back to, which is highly the case when using an experimental rom.

    See DevDB download section.

    BUILD12032016

    Note that this rom is pure stock and does not come with the Play Store or any Gapps, I suggest you download a micro gapps package separately and install it via recovery.

    There have been reports that recent versions of open gapps don't work properly, it is advised to use older versions instead (e.g. open_gapps-arm-6.0-nano-20161109.zip)

    Installation Instructions
    ==================

    Perform a backup of all of your important files. This ROM is experimental and I will not be responsible for your loss of data.

    Download the zip file and extract the tar.

    Use Odin/Heimdall to flash the tar file to your device. If you are coming from stock oranother rom make sure you wipe first using TWRP. Coming from a previous version of OMNIRom for SM-T285 may not require a wipe, however please perform a wipe if you encounter problems.

    Root and customization
    ===================

    This ROM is a purely based on source and is not rooted out of the box. However you can easily root it by using TWRP to install the latest version of SuperSU.

    If you want to customize this ROM and repackage it you may use this guide as a reference.

    I can't get Soft Keys to work, worked fine on the Omni ROM, only problem I have come across so far.

    needs some xml changes that needs to be compiled into the framework for that I believe. Though there are more critical bugs I need to fix with this 7.1 rom.

    thank for your awesome work, but i cant download any app from Playstore, it's downloading for a long time, i tried many way to force it works but nothing change. Have any one meet this trouble?

    Try using an older gapps package like from october, recent versions seem to have issues.
