Where is "Developer Options" category?

To activate 'Developer Options' category in Settings you need to tap 7 times on 'Build number' located into Settings -> About Phone.

What can i do to fix VOIP audio calls?

There's not a real fix yet, so i found this useful workaround that could help you.

If you need to make a VOIP call:

1) Play something using stock music player (also third-party music players SHOULD be fine)

2) Do not pause audio playback

3) Make a call using your preferred VOIP app.

Or you can just use a Wired Headphone/Headset | BT Headphone/Headset.

This workaround should work also for incoming VOIP calls.

How can i solve problems with Hebrew language?

Go to "Developer Options" in Settings and check "Force RTL layout direction".

What can i do to reduce the "echo effect" while in-call?

Try to reduce in-call earpiece volume (if possible). Shouldn't be required on latest builds.

I'm having problems with battery life, what can i do?

1) Use "Greenify" to hibernate all apps with a "little cloud + 'Gcm' word inside" on the right of each app's name. Donation version is recommended because it allows deeper hibernation of apps

2) Disable "Location" or set it to mode "Battery Saving" (Settings -> Location)

3) Make sure that your 2G/3G mobile network signal level isn't always low or unstable

4) Deny "Wake Up" and "Keep Awake" permissions to Google and third-party apps. (Settings -> Privacy -> Privacy Guard -> Press menu button and check "Show built-in apps" -> Press menu button again and go to Advanced -> Horizontal Scroll to Device)

5) Disable "Sync" or sync only useful stuff like Contacts

6) Disable "Auto-rotate screen" (Settings -> Display & lights -> Rotation)

7) Use one of the latest Modem/Baseband listed on first post.

8) Disable Ambient Display

9) Install Xposed Framework and configure Amplify

If this isn't enough then replace your battery and/or reduce your phone usage. :silly:

Is GearCM OTA supported?

Yes :) (Since 20150707 Build)

Why is my phone over-heating while playing heavy-games or running heavy-apps?

Use a bit your brain to explain why. High CPU and GPU usage = high heat production. Your phone will automatically throttle CPU when needed so don't worry, it is safe and normal.

Can I use another kernel instead of the one included in the zip?

No. Only use the included kernel for 100% compatibility, bug reports with non-standard kernel will be ignored.

Can i disable S-View cover features (lock/unlock)?

Not yet.

*** IR Remote app isn't working anymore/was working on previous builds/causes my phone to crash, what can i do?

Contact *** IR Remote app developer.

Any question about "Can't connect to camera" issue

Do not "stress" camera because we don't use yet a proper implementation. (Exynos limited open-source env.) Just Open & Close Camera apps carefully without force-closing them. (and do not do this frequently)
