Fix, Galaxy S20 Plus Lagging After a Software Update

Clear Cache from Recovery Mode

If you don’t know what recovery is, the first thing the bootloader rings up is recovery. Recovery Mode refers to a special bootable partition, which contains a recovery application installed in it. And you can fix some problems with your phone. Follow the steps to clear cache from recovery mode:

Turn off your phone.

Once it is turned off, Press and hold power/Bixby and the volume down button simultaneously until the Android logo pops up.

When the green Android logo displays, release both buttons.

The Recovery screen menu will now appear.

Use the Volume button to go to Wipe Cache Partition, then press the Power button to confirm the selection.

Wait until your device wipes out all cache or temporary data from the system partition.

Press the Power button again to reboot the device.

This clears all the temporary data from the device. And then it works like new.

Update apps

Tap Auto-update apps.
Tap Over wifi only (select Over any network if you don’t have wifi).
Tap Done.

Troubleshoot apps in Safe Mode

In case you don’t know what safe mode is, in safe mode, the system temporarily disables all third-party applications you installed on your device. By doing this, we can figure out which app is occurring the problem. Follow the below step to turn Safe Mode on:

When the SAMSUNG logo appears on the screen, release the Power key.
Immediately after releasing the Power key, press and hold the Volume down key.

Release the Volume down key when you see Safe Mode.

Tap on Apps.
Tap See All Apps.

Tap Uninstall.
Tap OK to confirm.

Factory Reset

Open the Settings from the launcher.
Scroll to and tap General management.

Select Factory data reset.
Tap Reset to continue.

Visit the Service Centre

Although it’s rare, some cases of the issues on Samsung Galaxy devices may have bad hardware as the origin. If a factory reset doesn’t help fix your issue, visit your local Samsung store or Service Center so a qualified Samsung technician can examine the hardware. If needed, they may send it in for repair or replacement.

Conclusion

By following all these methods step-by-step, we can expect that you’ve fixed or solved the lagging or performance drop or stuttering issue on your Samsung Galaxy S20 Plus device. However, if your device is bricked or stuck on the bootloop issue, you can re-install the stock firmware on your handset to get back on track. But if you’ve decided to go to the nearest service center under warranty, make sure that the device isn’t rooted or the bootloader is not unlocked.
