Updating your phone may result in a loss of saved data depending on the condition of your phone (malfunctioning, damaged, water seepage, etc.). You must back up all critical information before updating your phone firmware.
Note: Updating your phone firmware may not permanently erase all data from your phone, including personal information.
Confirm Your Phone Software Version
Before installing a system software update, you can check first what Android version you have on your phone.
- Tap > > Settings > About.
- Tap Software information.
- The Android and software version are displayed.
To back up your Gmail information:
- Tap > > Settings > Accounts & sync.
- Do any of the following:
- Turn on the Auto sync option. When auto sync is on, Gmail email, Calendar, and Contacts automatically synchronize whenever a change is made.
- Tap Google, select the Google Account you want to back up, and then select the items you want to synchronize. Tap > Sync now to sync your Google Account information.
To back up your Google applications:
Applications you’ve purchased from Google Play are reloaded remotely and can be re-installed after the update is applied. After the update, make sure that you add your Google Account on the phone.
- Tap > > Play Store.
- Tap to open the slideout menu.
- Tap My apps & games, swipe to the All tab, and then tap the app you want to restore.
- Follow the onscreen instructions.
As an added precaution, to preserve any data on your microSD card, please unmount it from your phone prior to starting the update process. See Storage Settings for details.
Enable Automatic Updates
You can choose to automatically download and install software updates.
- Tap > > Settings > System updates.
- Tap HTC software update.
- To save on data usage, you can choose to update through Wi-Fi only.
- Choose whether to auto-download system updates, app updates, or both.
Note: App updates are installed automatically. You'll still need to confirm when to install system software updates.
