Re: My phone (Casio G'zone Commando 4G LTE) is lagging.
Welcome to Android Central! There are a few things you could try before going to a hard reset:
1. If you have an SD card inserted, unmount it (in
Settings>Storage), remove it, then reboot. A corrupt SD card can impact performance.
2. Try uninstalling apps that you never use.
3. Also try disabling any preinstalled bloatware that you never use--go to
Settings>Apps>All, select the app in question, and tap Disable. You can always re-enable it if disabling it causes any issues.
Unfortunately (and oddly), your phone doesn't allow Safe Mode (which prevents all 3rd party apps from starting up, and can be a helpful troubleshooting method).
Safe Mode Android | Verizon Wireless. It also doesn't allow access to the Recovery Menu in order to clear the system cache partition, which can also be helpful sometimes.
