[LG G Pad X 8.0 Guides, News, & Discussion] avishah395:
This thread is for those that picked up a T-Mobile G Pad X 8.0 from the free after rebate promotion, here's a good thread to ask questions until we get a separate forum. Our device will initially get what XDA calls Enhanced Tags (ET)/(Topics). This means threads for the device can be found listed together when someone looks up the device finder/search. These ET devices, if they prove popular and achieve around 4 pages of threads are then given a full set of dedicated forums. Once achieved, we can request a dedicated LG G PAD III/X 8.0 Forum. Information will be filled in as other members report them or as I find them. This tablet is very similar to the LG G Pad III in South Korea (v525) and Canada (v522). This tablet is exactly the same, hardware wise, as the LG G Pad X 8.0 for AT&T (v520). While this thread is mainly focused on the T-Mobile variant, you'll find information, bounties and development applicable/compatible with other variants as well.

4. Toggle the setting 'Off' and the change will be immediate.

Adoptable storage:

(?)

1. Open your command window / terminal on your computer and type the 'adb shell' command with your phone connected.

2. Type 'sm list-disks' to list the disks available for adoption. It'll look something like below - take note of the disk ID (disk:179:160 or disk:179,160).

3. Partition the disk. To partition the disk above as fully adopted storage, use the command 'sm partition disk:179,160 private'. If 50/50 split between adopted and regular is desired, use the command 'sm partition disk:179,160 mixed 50'

4. Migrate data (Example)

NOTE: You will need 'Developer settings' enabled, Android Debug Utility installed and 'USB debugging' enabled to be able to follow these steps.

Troubleshooting

Q: My tablet says 'Cannot record video when another app is using audio' when trying to record a video.

A: This may be because Google Now 'Ok Google' is enabled on all screens. Try disabling this option.

Q: My tablet is having trouble with playing videos in MX Player and other 3rd party players.

A: This may be because of the 'Improve Playback Quality' option in Display settings. Try disabling this option.
