Tbh, if the hardware buttons are being finicky, you can usually just do it through the software menu if the phone stays on long enough!! It's basically the same result but way less finger gymnastics lol. Here is how I usually do it: * Go into your Settings menu
* Look for Privacy or Backup & Reset (the wording might be slightly different depending on your firmware version)
* Select 'Factory data reset' and confirm From a cost perspective, this is definitely your best bet since it's free. But honestly, if the reset doesn't fix the lag, it might just be the hardware showing its age. If you end up needing a replacement, you can find a used LG G7 ThinQ or an LG Stylo 6 for under $100 these days, which would be a massive upgrade. Just make sure to pop out your SanDisk microSD card before the reset so you don't accidentally wipe your photos (at least that's what I always do to be safe)!!!

Lol I was literally about to post the same thing. Glad someone else brought it up.

Noted!

To perform a hard reset on an LG Optimus Big LU6800:

1. Power off the phone completely
2. Press and hold the Volume Down + Home + Power buttons simultaneously
3. When the LG logo appears, release the Power button briefly, then press it again while continuing to hold the other buttons
4. When the factory reset screen appears, use volume buttons to navigate to "Yes" and press the Power button to confirm
5. Wait for the reset process to complete and the phone to restart

Important: A hard reset will erase all data on your phone, including apps, contacts, messages, and settings. Make sure to back up any important data before proceeding.
