Changing User Interface In Android

[RobotLizard]

I'm looking to buy either an LG G4C, or a Huawei P8. After extensive research, I have found that both phones are extremely similar and it will only come down to personal preference. Currently, I am leaning towards the Huawei, however after looking at the UI of both phones, I prefer LG's 'Optimus UX 4.0 UI.'

I was wondering if there was a way to change the UI on the phone? Both phones run the Android 5.0 operating system, the only difference is the user interface that each brand has created. If there is a way to change the UI of the Huawei P8 to the UI of the LG, could you explain it?

Also, please let me know if this will in any way harm the phone or its integrity. (I.E. can it void the warranty, cause crashes etc.) I know that you can jailbreak an iPhone to give it a whole new operating system, but this voids your warranty and could cause overheating and other internal damage.

you dont need to jailbreak or in this case root android phones as they are not locked up pieces of crap like iphones. the Google play store is filled to the brim with launchers and themes that change every aspect of your phone. legal, warranty safe, and easy
