Potential solutions to fix lags and freezes on your Xperiz XZ Premium

The subsequent solutions I have mapped out in this section are comprised of generic solutions or standard procedures, and applicable workarounds that are used to deal with performance issues in Android devices particularly the Sony Xperia XZ Premium handset. There’s no definite fix, hence you may have to try and retry until the ultimate solution is acquired. Begin whenever you’re ready.

First solution: Restart or Forced restart your Sony Xperia XZ Premium.

Minor software glitches can likewise cause your device to misbehave at times. And in this case, a soft reset or simple reboot could be the best remedy. Here’s how it’s done:

  1. Press and hold down the Power key.
  2. When the menu appears, tap Restart.
  3. Wait for your device to restart automatically.

Alternatively, you can do a forced restart. A forced restart will shut down or restart your device forcibly if it’s not responding or freezing. Just like a soft reset, a forced restart will not affect any of your settings and personal data. Here’s how a forced restart is done:

  1. Simultaneously press and hold down the Power key and the Volume Up key for about 6 seconds.
  2. When your phone vibrates once, release both keys. Doing so forces your device to restart.
  3. If you wish to force shutdown instead, keep holding down both keys until the phone vibrates three times and then powers down.

Second solution: Boot into safe mode.

Third-party apps or downloaded apps and files may also affect your device performance or cause it to misbehave. To find out whether a downloaded app is causing the problem, try to boot your Sony Xperia XZ Premium into safe mode. Follow these steps to boot into safe mode or enable safe mode on your Xperia XZ Premium:

  1. With your device turned on, press and hold down the Power key until a pop up window appears.
  2. Touch and hold the Power off option from the pop-up screen until the Reboot safe mode message appears.
  3. Tap OK to enable safe mode.

While in safe mode, use your phone as you normally do and see if it’s still lagging or freezing. If the problem does not occur while in safe mode, try to uninstall any suspected apps, most likely the most recent apps you’ve downloaded before the onset of the problem. That app could be the culprit and therefore needs to be deleted.

To exit safe mode, just restart your phone.

Third solution: Check and manage internal memory.

Insufficient memory can also trigger performance issues in mobile devices including frequent crashes, lags, freezes and infinite reboots. That said, make sure your device has ample of storage space to carry out input commands and processes in a smooth manner.

To view and check current memory status of your phone, go to Settings-> Storage.

Check and ensure that the internal storage space available is not lower than 500 MB. Otherwise, you will need to free up some space by deleting unwanted apps and contents from your phone. The problem you’re facing could likely be attributed to insufficient memory space on your device. Closing running apps, moving multimedia files to external drives can also help.

Fourth solution: Update software to the latest version.

Software updates can potentially fix software issues that might have caused your device to misbehave or become unstable. Updates also bring in new features and enhanced functions to optimize your phone system.

  1. To check for over-the-air (OTA) updates on Xperia XZ Premium Android 8.0, go to Settings-> System-> Software Update.
  2. In Android 7.x or lower versions, go to Settings-> About  phone-> Software Update menu.
  3. If an update is available, follow the onscreen instructions to proceed with the update download and installation.

If your device is up to date but the problem persists, consider performing a factory reset.

Last option: Hard reset or factory reset.

There are three ways to perform a hard reset or factory reset on Sony Xperia XZ Premium. You can do a hard reset through the settings menu, reset customization code, and via Xperia Companion. All three reset procedures will erase all your critical data and personal information so you should create a backup of your phone data beforehand.

Make sure your phone has ample of battery power to prevent interruptions in the later process. There is a chance that your phone will be damaged permanently if the reset procedure gets interrupted. If necessary, charge your phone before you begin. When everything is ready, proceed with the steps below.

Note: Back up important data to a memory card or external storage devices. Be sure to remove any encryption to ensure access to the files after the reset.

Hard reset Sony Xperia XZ Premium through Settings menu:

  • Tap Settings from the Home screen to get started.
  • Tap System.
  • Select Reset.
  • Tap Factory data reset.
  • Tap Reset phone.
  • If prompted, enter the device password, PIN or draw the unlock pattern to continue.
  • Tap Erase everything to confirm operation.

Wait until the reset is complete then proceed with the initial device setup.

Hard reset Sony Xperia XZ Premium using reset customization code:

  • If necessary, press the Power key to turn on your device.
  • Open the Dialer app.
  • Then type in this code:  *#*#7378423#*#*
  • Select the Customization Settings option from the menu screen that shows up.
  • Then choose Reset customization.
  • You will then be prompted with a message saying that “Data will be cleared and factory data reset will perform.”
  • Tap on Reset customization and reboot to confirm the operation.

Hard reset using Xperia Companion software:

If Apple has iTunes, Sony also has its very own device management software called the Xperia Companion tool. To use this software, download a compatible version on your computer, connect your Xperia XZ Premium to your computer, open the software, wait until it recognizes your phone, and then follow the onscreen instructions to reset your device software.
