How to pimp your LG G2 with the all-new flat Optimus interface from the G3

Like every self-respecting phone maker these days, LG also ditched the flashy, colorful and multidimensional icons and menus of its Optimus overlay, for a flat and clean, minimalistic interface. The LG G3 is the first phone that carries the new Optimus UI, and LG even went to great lengths, explaining why such a simple and clean interface makes more sense from a usability point of view.

We have to agree that the new Optimus UI is an enormous improvement over the aging and cartoonish previous versions, like the one you can find on the G2. Even after the KitKat update, its UI remained almost the same - very rich in functionality, but with a look and feel of those midrange launcher you can grab from the Play Store in droves. Did you know, however, that the new G3 interface has already be ported to the G2 by developer OptimusRs? Yep, if you don't mind tweaking your handsets, you can get the exact look and features of the new G3, plus a number of extra improvements, like the ability to record 4K video, and use the Magic Focus trickery. As you may have guessed already, there's a new LG G2 custom ROM in town, called the Optimus G3 ROM, and it will bring the above goodies to your G2 in a jiffy. Here's how to install it:

1. Root your LG G2, if you haven't done this already. Be forewarned that rooting may void your warranty, prevent you from installing OTA updates, make you bold, and other assorted problems, at least until you roll it back. Check out a brief video tutorial on rooting the G2 if you encounter problems.

2. Flash TWRP, Philz, or CWM custom recovery for your G2 by using the Simple Tool V3.2 For LG G2. If you don't know what this is, or how to go about installing one, you can read our dedicated Android custom recovery article.

3. Do a full reset of your G2, including wiping your internal storage.

4. Download the OptimusG3 v1.0 custom ROM, load in on the G2, and flash it by pointing the custom recovery of choice you loaded in step 2 to the new ROM.

5. If you haven't already, install the latest KK Baseband, too.

6. That's it, you should now have the flat and simple, yet feature-rich G3 interface on your G2, breathing new life in LG's last year finest. This ROM is based on the Korean F400 version, but it's been cleaned up from the Korean carrier apps, bloatware, and deodexed. You also get the LG G3 Camera 4K And 120FPS with Magic Focus, plus more camera tweaks. In addition, there are 13 unlock effects, new themes, ringtones, wallpapers, and notification sounds, so it's actually an improved version of the G3 interface, right on your G2.

Won't those icons get extremely tiny(not sure) for scaling from QHD to FHD?

Or u could install a replica without root on most LG new smartphones called LG G3 Multi Home from RocketSauceWare for free and no permissions on Play Store or many others from the same xda dev called RocketSauce83 on xda developers! He's a great guy. Please don't install the same themes from other 'devs' as they ripped his themes and one even put most of them on Play Store and sold them for a premium without authorisation before getting banned!!

Why don't lg just update it to new ui?

6. alouden unregistered

They will. Eventually. But between LG and the individual carriers, the eventual release will take time.

No complaints about battery. I get through a day using my phone. I don't really monitor it since it's not a problem. Also I'm usually next to a charger.

Yeah, I turned off the ''Smart Charging" and it works great. :) I love it.

It probably should be mentioned that this is NOT meant for the Verizon version of the G2 (VS980), before too many people brick their phones.

Why? Could you please elaborate?

I have the Verizon version (VS980) and its working great! Just be sure to flash the vs980 kitkat baseband.

12. davin8r unregistered

Ok, I stand corrected. Usually the VS980 requires separate ROMS than the other variants.
