[T-Mobile LG G2x] player911:
Congratulations on your new Purchase. The Tmobile LG G2x is a beast. Like all new devices, you may experience new service options and features you may not be familiar with and may cause some trouble down the line if not set up properly. We also want to make sure you are away of all of the known issues and some faulty units so you are aware and can check while still within a reasonable exchange window.

1. Get Connected! By default you won't be able to access the SD card via USB because it is defaulted to mount the Internal Storage, which requires the LG Driver.

To get around this, or if you only want/need access to the SDCard go to [Settings>SDCard and Phone Storage] and check "Mass Storage Only". This option doesn't require special drivers and will operate like most other phones.

The folder hierarchy is as follows:

Internal Storage: /sdcard
External Storage: /sdcard/_ExternalSD

1A. How to Delete your LG Drivers to use MASS STORAGE and to advert the Blue Screen of Death:

Obviously on Windows: Go to Start>Control Panel>Programs and Features find "LG Android Drivers" in the list and uninstall.

2. The first big problem on a few handsets is a backlight bleeding. You can test this by viewing a black screen in a dark room. You should have a solid color throughout. If you have really bad bright corners, you may be a victim of the bleed. While not quite a set back, it may be noticeable while watching movies or playing games in the future. If this is something that bothers you, I advise to swap it out for another unit.

3. There seems to be lots of "weird" issues ranging from grayed out options or behaviors such as lockscreen sounds not working. Most are assumed from faulty Titanium Backup restores or by simply skipping the initial setup. It is recommended that if you have done any of these things, to do hard format and set it up manually, recreating backups and program restores.

4. Like other later handsets by Tmobile, you may see WiFi Calling in the App Drawer. It works fantastic and is great for desperate times when you don't have available cell service. What you need to know is that it is ENABLED by default. The problem is WiFi Calling is designed to disable your actual Cell radio to save battery. What this means is that if you enable your Wireless and bounce around stores or in/out of WiFi service, you may be missing calls and messages while you are offline.

I recommend turning WiFi Calling OFF and enabling it only when needed.

5. WiFi is set to go into sleep mode after X amount of inactive minutes to conserve battery also. While a great feature, if used in conjunction with WiFi Calling, you may find your WiFi goes to sleep and you can start missing calls and messages also. To change this to go [Settings>Wireless & networks>WiFi Settings] + Hit Menu>Advanced]:

Change WiFi Sleep Policy to: Never

6. LG, like most other manufactures, develop their own drivers which may or may not be compatible with everything. With the LG G2x we are finding that some Bluetooth profiles may not play nice with your gadgets. Please check these as soon as possible. Some items may be Car Stereos, Specific programs using certain bluetooth profiles, and handheld gadgets such as gamepads or wireless speakers. Most will work but a few reports suggest the drivers may be off. Again, for your satisfaction, please check as soon as possible.

7. Root:

-Enable "USB debugging" [Settings>Applications>Development] and connect your phone to your computer via USB.

-Install ADB Drivers LG Driver.

-Run SuperOneClick: SuperOneClick

-Choose the option "Root".

8. Get rid of Bloatware using Root and Root Explorer (from market):

Here are a list of apps you can delete from the (/system/app/) folder:

AppPack
TeleNav
NOVA Demo
NFSShift
LMIRescue (LogMeIn.Rescue)
LMIRescueSecurity
EAPK = EA Mobile
MyAccount.apk = "My Account" and "My Device"
ZinioReader
ZinioSettingsProvider

9. There was also a report of using a HTC EVO Micro HDMI cable that shorted out the phone. This was a big deal over in the EVO thread. The problem is the way the cable was made and can short out with the external metal casing. If you purchased one of these I would proceed with caution.

10. If you want to make a solid backup of your current configuration or FLASH ROMS then you'll need ClockworkMod Recovery. There are two current methods to doing this. Both work but this is the best option because you can boot into Recovery via Volume Down + Power in case something gets screwed up and you get thrown into a Bootloop. The other method is by simply downloading Rom Manager via the Market and installing it that way. Although the second method does not allow booting directly into the Recovery console. So just do yourself a favor and download the latest ClockWorkMod NvFlash App for Windows
