Hello
Disclaimer: While this is a Sonos Community there are outside factors that can have a negative impact on your listening enjoyment. One of those factors is your device. While I will be discussing the iPhone the information presented is by no means intended to sway you away from Android. A poster had issues with the Sonos app crashing/unexpectedly stopping. I provided the following information that resolved the issue. Let’s begin….
This information may be helpful if you are experiencing frequent crashes or unexpected shutdown of the Sonos App on your iPhone. Here’s a link to Apple with some suggested trouble shooting.
However, the link doesn't mention checking your iPhone Storage and use of iCloud to store your photos; that will free up iPhone storage, assuming you are an avid picture taker. Storage can also be an issue affecting performance on Android as well.
How to Check iPhone Storage
- Go to Settings > General > iPhone Storage.
- Off load unused Apps and their data, delete messages, delete large files or anything you don’t need on your iPhone
How to use iCloud for photos and maximize your iPhone storage and protect your valuable data
- You can get 50GB of iCloud storage for 99 cents plus tax per month (USD).
- You can get more storage if you desire (for a fee of course).
- Photos can consume big chunks of storage. on your iPhone. If you already have iCloud storage go to Settings > Click on your name > iCloud > Photos > Sync This Phone > Optimize Photos.
- Your photos will still be visible on your phone but the majority of the KB/MB’s will be stored in iCloud. Think a 1MB photo with a 500KB “thumbnail” stored on your phone. The Full 1MB is stored in iCloud. You can download the full resolution photo to a computer or thumb drive to print
- The other advantage to use iCloud storage is that you can back up everything on your phone and in case of a data loss restore the entire system. Also the backups occur automatically when your phone is locked and connected to WiFi and you can allow backups over cellular.
- You can also back up your phone to a computer if you don’t want to pay for storage
- iCloud offers others feature/benefits as well
I hope this information proves useful and may save you the time of posting in the community for an answer to a similar issue you may be able to resolve yourself.
