The code needs to be looked at on this test because this is considered to be a 911 nuisance call and some cities will charge/fine you for non-emergency and nuisance calls. ### 5/5 — Easy and useful! *2026-01-01* So simple to use and quickly tested many functions on my phone. **Developer response:** Thank you! I'm glad to hear that you find it simple to use and were able to quickly test out the features. 😊 ## Frequently asked questions about Phone Diagnostics Expert ### What is Phone Diagnostics Expert?
