If you own the popular Android LG G2 smartphone, you are in for a treat today! This detailed guide post will help you modify your LG G2 to gain some fun shooting experience! This step by step post intends to help you shoot 4K videos on LG G2 along with slo-mo 120 fps clips.

This has been possible because of XDA developer xdabbeb who has developed this useful LG G2 mod tweaking with the software to use the capability of the amazing camera hardware. Using the support from Android KitKat update, developer has taken advantage of LG G2 hardware and is offering a plenty of improvements in the camera software.

The camera hardware itself is very capable, but LG didn't do much on the software end to balance out the performance in different lighting situations. I hope this mod can begin to solve these issues and even add functionality that is missing in the stock app - for complete changelog, please check this XDA Forum.

As you can read in the changelog too (pasted below in parts), this mod not only offers 4K video and slo-mo shooting, but also provides other improvements in the camera app including HDR video mode, low-light photography and more!

LG G2 camera mod changelog:

Version 1.1.0:

• NEW HDR Video Mode
  • Select it from the MODE menu while in video recorder
  • Doesn't do the over-saturated thing the HDR photo mode does, but does increase micro contrast in uneven lighting environments.
  • Will only work in 30fps target mode. If you are in 60fps mode it will kick you down when you select HDR Recording.
• NEW 1600 ISO Mode
  • Now you can set an ISO of 1600 manually, giving the Normal mode even more flexibility
  • Combining these settings with the brightness slider you can achieve even more variety, and the shutter speed still won't drop below 1/10.
  • I may bump the shutter speed of Normal mode further in the next version due to the expanded range it now has to take photos in low-light.
• NEW 60fps 720p Mode
  • File names should now be the date stamp for everyone.
  • Just select it from the size dropdown list in Video Recorder
  • You still have the option of 720p @ 24-30fps as well.
• I'm still looking into IA mode saving on exit. The other method posted in this thread doesn't work.
• There may have been some other things, but those are the big ones for now
• There's also an alternate version available that silences the record start/stop and focus sounds

Version 2.0.5:

• NEW 4kUHD and 120fps video recording modes
• Same additions and features as the previous versions
• This version is for 4.4.2 stock KitKat builds only.
