Solution 1. Make sure your Windows phone is not running low on space

Devices need to have enough free space to perform well. Don't forget that security updates that you regularly download also take space, leaving less of it for applications and their updates. For that reason, low disk space might result in an 805a8011 error. Delete some of the photos, audio or audio files, and applications you do not use. Additionally, you can purchase an SD card[ref en-3] and move your files there. When you are sure that enough space was freed, go to the Windows Store and check if the error code 805a8011 is preventing you from using the store.

Solution 2. Check your time and date settings

Check if the time and date are correct on your phone. Go to the Settings and find Time and Date section. If the values are not right, change them. Then, try accessing the Windows store.

Solution 3. Check for Microsoft account syncing issues

To fix synchronization issues you have to follow these steps:

• In the Settings click Email + Account.
• Then tap on Microsoft account and hold it down.
• Tap on Synchronize.

Solution 4. Make sure internet connection is stable
