[Epic 4G General] KennyG123:
Thank you CM9 team for bringing the impossible to the best keyboard phone out there!

This thread is for us working slobs who are afraid of getting flamed in the Official CM9 threads. Flaming in this thread will not be tolerated and I will report flamers if necessary. This is a Tips sharing thread Of the people, By the people and For the people (cue patriotic pfife playing). I will attempt to keep relevant tips in the OP.

Here is the CM9 guides, FAQs and Status as well as download links in the Install Guide

And the CM9 Customization guide:

Tips:

To disable the "auto-add" of apps on your homescreens, go to "Market" "Settings" and uncheck "auto-add widgets".

TW Apps:

Ported TW apps in the app section work on CM9.

Voicemail:

Sprint Voicemail works. As well as 2 other options found here. You need to follow the instructions for download and installation. Thanks to Alias8818 for fixing the redraw issues.

Phantom Voicemail Notification:

Clearing data in phone.apk has worked for some. Danipoak and tbob18 stumbled across this gem that worked for them:

Auto-Rotation issues:

There are three separate options for this, one for the default launcher home screens:

(Menu > System Settings > Launcher > General > Auto-rotate screen)

one general use with apps:

(Menu > System Settings > Display > Auto-rotate screen) and another in

and in accessibility

(Menu > System Settings > Accessibility)

For those having rotation issues this has helped some..flash either a TW ROM or the EL30 temporary boot flashable and do the Horizontal Calibration. For real stubborn phones it is recommended to Odin back to EL30 stock, calibrate and move forward from there.

Themes:

There is no Theme Changer working yet, that is upstream. Themes for now have to be flashed traditionally. There are some good CM9 themes in the Themes subforum.

Screenshot:

If your on CM9 hold the power and volume down button. The it'll take a screenshot. Or just hold power button and select screen shot.

Gtalk:

If Gtalk is missing Big Goron has a solution here:

When you set up CM9 it keeps you logged in to Gtalk. Make sure to sign out to conserve battery (thanks Meetface).

Wired Tether:

If anyone is having trouble getting the Wired Tether 1.4 to work here is how:

IMPORTANT: USB debugging must be off. With cable unplugged and usb debugging off start the Wired Tether 1.4. Click to start tethering. Now connect the cable to the PC. It will install drivers (again...I know). When it completes the driver installation a new network will appear and $$$ Profit.

Native Wifi Tether:

If the built in Tether shuts off on you try leaving it on and rebooting. If it still doesn't work toggle it off and on. It may connect, disconnect then connect and start working.

100Mhz minimum frequency issues:

It is recommended by the CM9 team to flash this ROM and not change the kernel or any governor settings and your phone will drop to 100 Mhz. They also state the default setting is the best for battery life.

Thanks to all that have contributed. If you really like one of these tips find the post and thank that person. If you see a tip I missed and think it needs to be here in the OP please PM me.
