[Galaxy S III Android Development] CodeFinder:
Here are my detailed experiences with build 2016/11/09 of CM14.1 (open_gapps-arm-7.1-pico-20161110) on GT-I9300 (clean install, no restore:

Device related:

- flashlight turns off itself after some time. To reproduce it: enable flashlight, turn off screen/switch to standby, wait a few seconds-> light turns off (and stays off when waking up the device, flashlight button "thinks" that light is on)

- home screen is visible for a short period of time when unlocking the phone (not a big deal, I assume this is due to the Mali blob quickfix)

- phone does not reconnect to my WiFi at home, need to reboot (airplane mode doesn't help); does not happen at work/university (and didn't happen with CM13, home WiFi didn't change); tried 2 other WiFis and another router at home: same problem (haven't flashed/tried murata WiFi fix); this is very annoying. It was already a problem on one of the previous CM14(.1?) builds.

EDIT-1: I tried other various WiFi related settings w/o luck.

EDIT-2: WiFi problems gone! Manually solved in TWRP with murata fix as described here (German, sry): https://android-hubo.de/thread/5014-rom-i9300-7-1-cyanogenmod-14-1-unofficial/

- MTP host fc's sometimes (can be ignored)

- observed that I got no notifications in messenger (Telegram), probably an issue with Doze or battery optimizations; disabled it for Telegram and it seems to work now.

- display/rendering: some minor (!) scrolling glitches/bugs (seen when selecting a file using CM's file manager app), home screen issues (described above) and some buttons during initial CM screens were drawn wrong

- EDIT-1: first reboot w/o any obvious reason (was just browsing the web)

(Probably just) CM14.1 related:

- cannot access ext. SD card with CM file manager (and many other apps); however, the "Downloads" app can access SD card memory

EDIT-6: 'solved' with ES File Explorer app

- Gallery app doesn't load (remains black, no errors) when opened from another app (like viewing pictures in Camera or Telegram app).

EDIT-4: solved by clearing app data/cache

- calendar crashes when opening an .ics file (as file or K-9 mail attachment), already buggy in CM13

- gesture typing doesn't work although (re-)enabled in keyboard settings (default AOSP keyboard)

- themes are not working (theme engine missing)

- some translations (German) are missing (not an issue)

Boeffla kernel related:

- slow charging (100 mAh with 1100 mAh max, wall charger) @ boeffla-kernel-6.0-alpha5-CM14.0-i9300-UNOFFICIA.zip by [MENTION=5794998]MaxMustermann2.0[/MENTION]. This was immediately resolved when going back to stock kernel (= reflashing just CM14.1). This was also reported by others.

EDIT-3: Confirmed with "Ampere" measuring app, 1000mAh on stock kernel + wall charger (seems OK)

- OC the GPU to max speed caused my device to crash/reboot (CPU OC'ing was OK); needed to apply default config by flashing boeffla-config-reset-v4.zip from TWRP; this was possible on CM13 Boeffla kernel. Also reported by others.

Working:

- Bluetooth (like on CM13)

- WiFi

- SMS/calls, mobile internet (including HSPA+ and symbol), needed to explicitly switch to "3G preferred"

- battery/power management (deep sleep), charging (except w/ boeffla kernel, see above)

- sensors (proximity, light, accelerometer, gyroscope, pressure, magnetic field, gravity orientation)

- alarms

- FM radio using Spirit2 app

- stock camera ("cannot connect to camera" bug sometimes, like on CM13, EDIT-9: to fix it in CM14(.1) see http://xdaforums.com/general/general/guide-how-to-fix-connect-to-camera-t3496237 ), but very fast;

EDIT-5: photo, video, and panorama are working (play + record)

- mic, sound (speaker, calls, Bluetooth+cable heatset)

- (partial) screenshots

- all apps tested so far (except those issues listed above)

EDIT-7:

- GPS

- USB charging (~470mAh) + file transfer (infernal and SD card write+read)

EDIT-8:

- NFC

- Tethering / Hot-spot

All in all already a great ROM with excellent performance! Nice work [MENTION=3667135]pesci2k[/MENTION] [MENTION=5405215]forkbomb444[/MENTION] [MENTION=947981]Lord Boeffla[/MENTION] [MENTION=5794998]MaxMustermann2.0[/MENTION] ... !
