Q&A

Q : Why does it say Galaxy Tab S2 9.7 on Android File Host if this is for the 8.0 version ?
A : Android File Host doesn't feature the 8.0 version in their devices. Because of that, all is located under a folder called 8.0

Q : Why is everything so small?
A : The DPI rate is 320 which is the same as on the Stock rom. However, Samsung has made everything bigger. Since this is personal preference, you may always higher your DPI to make things bigger or lower your DPI to make things smaller under Settings > Display > DPI

Q : Will you ever work on CM13?
A : Yes, once we feel like CM12 is good enough, we will move to CM13

Great work!

Can't wait to use this once it reaches a point where it's functional for everyday use! Excellent work so far!

good news for all T810 users! @T_I is working on a port of my ROM. It came to the CM setup wizzard however had some problems with the touchscreen. Should hopefully be a easy fix.

So the sensor module just isn't loading.

I/        ( 3857): System server: starting sensor init.
D/SensorService( 3857): nuSensorService starting...
E/HAL     ( 3857): load: module=/system/lib/hw/sensors.exynos5.so
E/SensorService( 3857): couldn't load sensors module (Invalid argument)
I/        ( 3857): System server: sensor init done.

Tried to use the note 4 ones. They did load up successfully but use different drivers.

Ex the gyroscope uses ICM20610 where mine uses LSM6DS3. I really only came this far. My nightmare would be to make my own sensor libs. That would mean that I would have to learn lot's of lot's of coding!

Sadly those are for the kernel.

However,
I found this open source sensor for the s3 I9300 that uses a , what I believe, older version of the gyro found in our device. I will see what I can decompile/reverse out of the current module for the tab and will compare it with the open source ones for the I9300. This will be hard and I would be very thankfull if you could redict any expierienced dev you know, here

Suprise!

Turns out I was just missing a shared libary. That caused the module not to load. Sooo.... all that s3 sensor work for nothing

Hey.... atleast I learned something.

Also, build will be released in about 1-2h

Nice! Good job mate!

Did you have time to look at wifi yet? I would love to try it if that works!

Ok so to wifi :

I know most of you want as number 1. priority a working WIFI connection, but this doesn't seem to be that easy to fix, at least not for my empty brain. As you've probably already noticed, my debugging skills are still quite bad (Yes I'm still learning... Yes I'm not perfect.... well maybe yes... ok no just kidding). The current issue i'm facing has probably to do something with the api drivers and wpa_supplicant. I've noticed that the KMSG doesn't even show a tiny trace of the cfg80211 driver and the nl80211 driver. If any developer out there knows what to do with the following log output when trying to access the wifi HAL / Enabling WIFI please tell me.
