[E 2015 Original Android Development] Coodarah:
Reporting for Surnia CM 12.1 nightly@2015-06-24 (on XT1524)

I installed the nightly@2015-06-24, built 2015-06-23 (after properly going back to stock, XT1524, retde).

Installation was performed with leaving the original stock recovery in place (mfastboot boot <twrp-recovery.img>).

Tested in first place a couple of hours without any changes, no GApps.

Then tested a second longer period after installing:

UPDATE-SuperSU-2.46.zip via sideload

user apps

freezing system apps

tweaking user settings

again without GApps

Additionally changed (via root shell):

su
settings put global captive_portal_detection_enabled 0 # off
settings put global captive_portal_server 127.0.0.1 # localhost

_

Frozen system apps (in second test session):

Observations in both setups ("naked" ROM and customized):

W-LAN:

Slowly scanning/finding and after that slowly connecting to the (named/not hidden) W-LAN, static IP, fixed DNS (OpenDNS & CCC - Chaos Computer Club)

1. a regular Router g/n-Standard and also

2. an i7 notebook's Intel network card - used as a Intel MWT (My WiFi Technology) AP only g-Standard; Windows 7 professional, 64-bit, fully patched.

_

Brightness/Sensors:

There seems something not being right with the brightness control with adaptive brightness turned on:

In this mode brightness is correct as expected in the first place. - Then randomly goes "through the roof" (up to full brightness), never going down to an appropriate level. - Very easily to be seen if making a call or changing orientation. - Switching off and on the display gives back correct brightness, but only temporarily.

Only deactivating adaptive brightness and adjusting manually gives satisfaction, which is inconvenient.

_

When in a call the display is not switched off/on if you put the device to/away from your ear.

_

Internal Storage/USB (MTP mode):

There has been an issue here with several file explorers not acting well with the internal storage. - (Proper) permissions?

In CM Filemanager or i. e. Amaze a created file either doesn't show up in a directory containing the file at all or with a file size of zero ("0") byte on the computer.

Displayed files can't get copied to the computer.

SuperSU has additionally been set to "Mount namespace separation" "on" and also "off" for testing (with rebooting the device after, but causing no change to the MTP behavior described).

Also, in my opinion, it has nothing to do with the Privacy guard of CM.

I didn't test an external SD card.

Edit: After a reboot into stock recovery and a wipe cache the issue described above disappeared.

_

Using the short cut "Internal storage" in CM Filemanager leads to an error "The file or folder was not found", because the path "/storage/emulated/0/" isn't there/symlinked (init.<xyz>.rc ?).

_

Speakers/Mic/Sounds:

Callers/called people told me, that my super-cheap Chinese wired headset and an expensive MW600 bluetooth headset perform better (understandable) than the integrated mic. - Maybe not ROM-specific. - All other functions are working well for me.

_

Heating:

No extraordinarily high values (up to 40 °C while gaming long periods), quickly settling down to ca. 33 °C - 37 °C. - Sometimes rising while charging (normal). - As a reference point: coming out of stand-by gives a temperature of 24.7 °C in an environment of 23 °C.

_

Battery duration:

Depends, but no fast battery drains/drops (without installed Google apps). - Screen on changes the power consumption significantly, the connectivity interfaces don't (which is good).

_

Apps:

Apps are opening a little bit slow sometimes (it depends). - Switching between apps can also need some time, but nothing like a showstopper for such a device running Android 5.x. - The RAM usage is always higher than in stock, but not "head shooting" apps off the RAM aggressively can be an advantage.

(Sorry for the missing logs this time.)

So far a rather useable ROM. - Thank you for your work.
