When I tried to update my Android OS 7.0 to Oreo, an issue occurred: I didn’t have enough space available on my smartphone. I goolged and found those tricks were useful:
- Delete all unused apps if you don’t need them
- Be smarter with power saving modes
- Clean all APP cache and kill background process
- Diagnose Your SD Card and make more space on phone
- Turn off GPS/Location (If don’t needed)
All the ways above, you may go to “Settings’ and find relevant options to optimize. But, if you think it’s not convenient, here is an APP may help you - Fast booster
