Step 2 — Test with another source

Play a local file or built-in tone. If that works but streaming fails, the app needs a cache clear or update rather than a hardware repair.

Update software where possible

Open Settings → General → iPhone/iPad Storage and remove huge downloads, unused offline maps/podcasts, and duplicate photos. Low storage makes iPhone 15 Pro misbehave in surprising ways.

Test in safe/guest mode if available, try another user profile, and note whether the fault is hardware-like (always) or software-like (intermittent after updates). Keep Settings changes documented so you can undo them.

Last resort: reset or recover

Step 7 — Last resort: reset or recover

Back up first. Then use Settings → General → Transfer or Reset → Reset only if earlier steps failed. After reset, set up iPhone 15 Pro without restoring a suspect backup immediately — test clean, then bring data back in stages.

When to get professional help

Stop and seek professional repair if you smell burning, see a swollen battery, notice liquid damage, or if the iPhone 15 Pro still shows no power after verified chargers and cables. For TVs and laptops with physical panel damage, software steps will not restore the screen.
