[PORT] linux kernel source for Xiaomi Redmi 3S (land) (Snapdragon 430 msm8937)

You might wanna take a look at this: https://github.com/nicknitewolf/and...mmit/675738623bc16aaf29758a12aee63b2110c670a8

This should likely fix the Goodix FP, though GPIO ports have to be remapped quite likely. Do you know stock Fingerprint ports?

Background: nicknitewolf and alex9yust ported ZUK Z2 Pro's Goodix driver to the Redmi Note 3 Pro AFAIK. It usually only supports the FPC1020 fingerprint driver in Xiaomi's code. Good luck!

I've got a tgz archive looks like the manufacture using for test.
This includes many origin files. I don't know whether it is useful or not.
The link is pan.baidu.com/s/1bpkbdcr
I am new XDA user so can't link outside img,plesase download attachments.

For cameras: @assusdan Suslov Danila is working on it.
https://github.com/yangyangnau/android_kernel_xiaomi_msm8937/issues/2
https://github.com/assusdan/android_kernel_xiaomi_msm8937

75% of camera works in Footej. Preview - work. Front can take photos (not sure about saving them). Rear can't take photos.

Also we can take photo in Footej when we are using low resolution (2.1 MP)

While testers test camera, successfully start builded cm13!

What's the erratic behaviour exactly like? Also do you know what sensors are built into the device?

yangyangnau · Nov 9, 2016 at 3:03 PM

BlueFlame4 said:

The kernel loaded fpc1020 and goodix_fp drivers, but it couldn't detect the fingerprint device.
The drivers need fix base on Redmi 3S's dts file.

BlueFlame4 said:

I'm not sure.
The fingerprint should be goodix 3208, since Redmi 3S is a budget phone.

Amazing, this will in the end grant the development for all of our Phone, IMHO. Okay i'll stop interrupting here, now

Very happy
