What is the optimal firmware for the LG-P705 smartphone?

Question

Android

Good day!
Can anyone come across, tell me?
The LG-P705 smartphone slows down and periodically freezes (reboot helps), although I use very little. Not rooted. Maybe there is some kind of optimal firmware for it? Now it's 4.1.2
I would be very grateful for useful links.
Thanks

The problem is not in the firmware.
