And here it is available for another device, and once again for an LG make. Previously, it was ported unofficially to the Nexus 4 and wrote a guide to Install Android L Developer Preview on Nexus 4. This time, we have come up with the LG Optimus G E975, which has been a brilliant smartphone of its range supporting Qualcomm Quad-core 1.5 GHz Krait processor, Adreno 320 Graphics unit, 13 MP camera, Dolby Sound Enhancement and a 4.7” HD-IPS Gorilla Glass display for a high-definition experience.

Developers are working hard on porting and bringing Android L support to as many devices. Now, the LG Optimus G is one of them, praises to XDA members Kevinjoa and ThatKawaiiGuyThe port is yet in its early beta stage and bugs have been discovered. Not every one of us here prefers stability over features. So, if you tend to operate on the latest version of Android on your Optimus G, you might have to risk a few device features. But do not worry, the bugs are being squashed by the developers the second you read this. A little bit of more patience and you will be served with the latest and still very stable build of Android L Developer Preview on LG Optimus G. Following are the bugs that have been discovered:

  • FC’s and hang-ups in the Camera app.
  • The device may heat up sometimes and hence the charging procedure is slow
  • NFC won’t work at all
  • Some Apps FC
  • A few Apps won’t work from Play Store since the default runtime is ART.
  • The data connection may terminate suddenly at times

Make sure to keep in mind that the ROM is pre-rooted with working root permissions. And as far as what I think, these are just a few minor issues, which will resolve over time and should not hold you back from using this port as a daily driver. Watch over to the Android L porting thread at XDA and you shall be highly convinced to use this ROM on daily basis.
