Galaxy S4 i9505 running official CyanogenMod 13 for jfltexx

So, I’ve made the jump to CM13 after a month since the nightly builds started to rollout. So here’s how it went!

CyanogenMod 13, Nightly build, February 1st.

(The whites are yellow because I have Live Display activated to not mess with my sleep cycles as much)


Live Display deactivated for those who are concerned with the yellow tint.

The upgrade

I did a dirty flash, also known as an in place upgrade. On CyanogenMod, they heavily emphasized that you need to immediately update your GApps and other 3rd party applications you might have installed in one go. I did that, but I am not sure what happens if you don’t heed that advice.

Start = CM 12.1 SNAPSHOT from November 17th, 2015
Turn off phone
Boot into ClockWorkMod Recovery
Clear cache
Clear dalvik
Flash zip file containing CM13 NIGHTLY from February 1st, 2016
Flash zip file containing OpenGApps for Marshmallow (I used nano)
Reboot
End = CM 13 NIGHTLY from February 1st, 2016

What seems to work completely

Phone calls – Sending and receiving
SMS – Sending and receiving
Data – Only tested HSPA, the i9505 does not have the LTE bands transmitted in Edmonton
WiFi – Wireless N and G seem to be OK
GPS – A little slower maybe? But accurate once lock is acquired
NFC – OK
Display – LiveDisplay as seen above works (it’s night, so the screen gets a warmer tone), hover touches also work
LED notification light – As seen above, the red light means I have a text message
Sound – Speaker, earpiece, headphone jack, all OK
Sensors – Proximity, IR sensor (for gestures), Accelerometer, Magnetic, Gyroscope, Temperature, Barometer, RGB, Humidity, Gravity, Orientation all OK
Buttons – Power, Home, Volume up and down work

What seems to work partially

Bluetooth – I was able pair with my stereo Bluetooth speakers OK, but attempts at pairing with a Pebble has caused a soft reboot.

What seems to not work

So far none that I’ve discovered

What seems to be missing when coming from CM12.1 Nightly

– Ring targets when you drag up from the home button. Right now it is still the standard Google Now
– Quick setting tile customization. It kept the layout that I had from CM12.1 but I cannot configure it

So, how is it?

Overall very smooth. Noticeable speed / smoothness improvement when juggling between applications. There is hardly any lag when switching between things. Marshmallow is an “incremental” update from lollipop so the phone feels more refined but not “oh it feels like a new phone”.

Battery life is the same as CM12.1. That means I can get through a day as usual.

I don’t use Bluetooth nor do I have it turned on so the fact that it only works partially did not bother me.

Currently I have no problems in using it as my primary phone.
