will it be possible to dirty flash this over your last cm13 build?

you wrote: LineageOS 14.1 is a free, community built distribution of Android 6.0 (Marshmallow)...

I think it should be 7.1 right? ?

Yes, you are correct, it should be 7.1. I suspect that dirty flashing over CM13 will not work but I have also not attempted it.

There is a short video on my blog; 2nd post. I can not get the screenshot page above to load properly so I can post screenshots... I'll continue to try...

just tried it... dirty flash over cm13 and flash new gapps works... :good:

 

[Meticulus]

WIFI BUG

FYI: Just noticed a crash in Wifi. Doesn't happen until trying to connect....

 

[NoMercyWWE]

Edit: OK worked, now...

Had nothing to do with the Rom but with Google nearby

I will Report Bugs as soon as i find them.

Anyway good Work so far ?

FYI: Just noticed a crash in Wifi. Doesn't happen until trying to connect....

Had no luck tells me to Unlock my other device to Transfer data..even when I click on cant Do this now..

Great news, do you plan on releasing the sources?

Working perfectly on my L31 ? thanks a lot for your time and efforts !
Everything is smooth like butter .

Only issue I got so far is the camera that is not working 25_01_2017 build and screen rotation not working yet due to sensors as mentioned.

Also screen rotation not working yet due to sensors as mentioned.

Are these the only bugs or did anyone recognize other bugs?

 

[mchtt]

Issues are noted here: http://www.meticulus.co.vu/

You may prefer the cm13 release for the moment as a daily driver.

Another bug i saw:
If i install another keyboard and then disable the stock one, the keyboard does not appear anymore in some apps until i re enable the stock one even if i'm not using it.

Hello!
Do you publish the code somewhere? Because I only found this http://www.meticulus.co.vu/p/blog-page.html and there is little to no activity in the last few weeks

Yes, but not at this early alpha stage.

P.S. Wifi + All sensors will be fixed next build...

Edit: Can you please edit your previous post and remove the "quote of the original post or (OP)". Thanks...

BTW I looked into the FM Radio again. This time I decompiled the apks and frameworks and found out that they are using modified FM Framework which looks something like this. The FM JNI library then registers those functions. So we can't use the stock JNI because it can't find the framework. Then they have created some service which communicates with the FM radio. The FM app then just calls the commands from the service. I didn't find any traces of QCOM FM radio so we have some BCM probably. So after I found out they have heavily modified all the opensourced code I stopped because we would need to reverse engineer a lot of things and it is not worth it in my opinion.

Reverse engineering is not the only option. Provided we could find the kernel driver, a user space driver could probably be written from scratch. I have some experience with FM kernel driver with my YP-G70. It had an "Si7102" (I think) FM chip. Although I was never entirely successful, I did try several times to write a user space driver for it. I was able to control the chip pretty well but I could not figure out how to integrate the audio output.

P.S. I finally wrote that sensors lib, I've been talking about since the beginning of CM13. Afaict, It works perfectly and that is how I fix the sensors.

Yeah the audio output.. They have some functions in the library like set_fm_volume probably used for that. I'm not sure if we could use it.

Fingerprint Fixed

Will be in next build.... I did find it rather difficult to get through enrollment though...

So any chance of having Stock camera optimized or we are going to have Google camera?
