When using your Sony Xperia PRO-I, you may experience crashing, freezing, random restarting and/or slowdowns. To see how you can potentially fix these issues, then you can check out this troubleshooting guide from Seeking Tech.
1. If you were using an app when the problems occurred, then we recommend closing the app if possible. The issue could be isolated to the current application or a combination of conflicting applications.
If you are only seeing problems when trying to use multiple apps at the same time on the Xperia PRO-I, then we recommend closing all the apps you have opened. Afterwards, you can try opening the apps one by one to see if a certain application, or a combination of applications, is the cause of the crashes or slowdowns.
2. You can also try updating the firmware of your smartphone as well as the software versions of the applications.
To update your apps, go to the Play Store app, tap your account icon and then select Manage apps & devices > Update all.
To update the firmware for your phone, go to the Settings app and then select System > Advanced > Software update.
3. Moreover, you can try clearing the data, cache and settings of the applications you have installed on the phone.
To do so, open the Settings app.
To clear app data, select Apps & notifications and then select an app. Next, you need to select Storage & cache > Clear storage > OK.
To clear app cache, tap Apps & notifications and then pick an app, Afterwards, tap Storage & cache > Clear cache.
To clear app settings, go to Apps & notifications and then choose an app. You then need to select Advanced > Open by default > Clear defaults.
4. If the internal storage of the Sony Xperia PRO-I is almost filled up, then your phone may end up crashing, freezing and/or slowing down.
Therefore, we recommend deleting any apps you don’t use often. You can also delete any photos or videos you have on your internal storage.
The Sony Xperia PRO-I supports microSD cards as you can add an additional 1 TB of storage. So, instead of deleting some files, you might want transfer them over to a memory card instead.

5. If your smartphone is unresponsive or not responding normally, then we recommend restarting it by pressing and then holding until the power menu shows up. Afterwards, you need to select Restart.
If you have low battery level, the restart process could fail. Therefore, you should make sure that you plug your phone into a power source if it has low battery life.

6. If the Xperia PRO-I is completely frozen and not responding to any of your touchscreen gestures, then you can try forcing it to shut down.
In order to force your phone to completely turn off, press and hold the Volume Up and Power keys at the same time. When the phone vibrate once, keep holding the same two keys for a few more seconds until it vibrates three more times.
After shutting down the phone, try to turn it back on again to see if it starts functioning normally again.
7. The crashing, freezing, random restarts and slowdowns could also be related to your Sony phone overheating.
The recommended operating temperature for the Sony Xperia PRO-I is -10°C to +35°C (or +14°F to +95°F). If the temperature exceeds +35°C or +95°F, then the phone may lower its performance until the temperature could be regulated.

To do so, you need to download the program to your computer or Mac.
After installation, open the program and then select “Software repair.” You can then follow the on-screen instructions to repair the software portion of your Xperia PRO-I.
9. One last step you can take if the aforementioned solutions did not work is to factory reset your phone. This process will erase all your personal data and custom settings on the device. Therefore, we highly recommend backing up the data stored on your phone before starting.
With your data backed up, open the Settings app and then select System > Advanced > Reset options. In the next screen select Erase all data (factory reset) and then Erase all data. Input your screen unlock pattern, PIN or password to continue and then select Erase all data to start the process.
