Honestly in the year of 2014 I have tried a few flagship phones and I ended up with the LG G3. My previous phone was the S5, I had to use nova launcher to cover that cartoonish look of TW. However, now when I am owning the G3, I dont feel that need and like all the stock launcher goodies like the widgets, grid and even all the stock wallpapers. Nice job LG, you listen to your customers !
Just moved to the G3 yesterday. Loved the visual styling but the launcher was laggy compared to Google Now or Nova. Set up Nova to be a more attractive version of LG's launcher.
Changing it pretty frequently... Maybe set up Nova again in a few days if i get bored or the Stock launcher which has been very good.
This is on the Nokia Z launcher right now.
