Android L gets ported for LG Optimus G E975 [GEE]

The Android L release is a huge update to the Android OS, we were expecting a rapid influx of Android L ports from the developer preview factory images that Google released for selected Nexus devices. However, as huge the Android L release update is, it seems it hasn’t been an easy road for our awesome developers at XDA to port Android L to other Android devices.

The LG Optimus G is only the second non-nexus device to get the Android L port, while the first being HTC One M7. Also, among the Nexus devices only Nexus 4 and Nexus 7 2012 have received the Android L port from developer preview factory images that Google released for Nexus 5 and Nexus 7 2013.

So there really are very few Android devices out there that are running on Android L. Lg Optimus G users, you’re among those few lucky people. Cheers to that!

The LG Optimus G Android L port has already progressed well, the build is at release 11 now and most of the bugs have been sorted out. The XDA thread of the Optimus G Android L port mentions the port as ready to be used as your daily driver. Let’s take a look at the issues that are still present on the ROM:

 icon-bug  Bugs/Issues on Optimus G Android L port

  • Camera is a bit buggy
  • NFC isn’t working
  • Heat issue
  • Slow charging (related to the heat issue)
  • For Sprint Optimus G, there’s workaround to get service (fix available)
  • Random device update force close issues (fix available)
  • No SD Card error on some apps (fix available)

NFC incompatibility shouldn’t be anything to stop you from using this ROM as your daily driver, as regards for other issues, they will be sorted out soon since devs already have found quick fixes for most of them. So without further ado, let’s hit the downloads section and flash this Android L ROM for Optimus G.

      STEP 3: INSTALLATION INSTRUCTIONS : For updates on the ROM, check the original page (http://forum.xda-developers.com/optimus-g-sprint/development/port-android-l-preview-gee-t2818325)
      Learn to read 🙂

      The link to original development page is there where it makes best sense — near the ROM’s download link. Also, the developers too are credited rightly in the Custom ROM Info box.

      This is not your usual news post where you’d find the source link at the bottom, it’s a ROM installation guide where the ROM’s file is the actual work of the developer and we feel it should be credited right there rather than putting a link at the bottom (after our long installation guide).
      Hope I’m clear enough.
