You might be thinking it's time to upgrade your Android phone if it's been slowing down many times a day. But, before you go out and buy a new one—assuming you've previously tried a simple restart—there are a few other things you can do to decrease or eliminate those unpleasant glitches.
Your Android phone's operating system must be updated.
Updates frequently offer speed and security enhancements as well as bug fixes. All of these elements are critical and can help accelerate the performance of your smartphone. Navigate to Settings > System update, then click Download and install to begin the installation process.
Turn off all animations in your browser.
Android's animations may no longer run properly on an old phone. If this describes you, you may want to disable animations on your Android phone. To do this, you must first enable developer mode on your device: Scroll to the bottom of the Settings > About phone screen. Activating developer mode on your Android phone is as simple as tapping seven times on the build number.
Scroll to the Drawing section under Settings > System > Developer options. Select Animation off from the menu after selecting Window animation scale. Then select the same option for the Transition animation scale and Animation duration scale.
There will be a change in the look and feel of your phone, but it will run faster, so it's worth it.
Improve the performance of slow apps to avoid crashes and freezes.
Some of the apps you use frequently may be running slowly. When using Facebook or Instagram, your phone may be slow, but everything else should be fine. Go to the Google Play Store and make sure all of your apps are current before you do anything else. In Play Store, tap your profile picture in the upper-right corner to access Manage apps and devices. Slowdowns in various Android apps may be resolved with new updates.
Factory reset your device.
If all else fails, you can perform a factory reset to clear all data and start over with a clean slate. This will erase everything on your smartphone, so use it only as a last resort. As a precaution, make sure your Android backups are working properly and back up your device.
After that, go to Settings > System > Advanced options > Erase all data (factory reset), and then follow the on-screen instructions.
