Does Your Phone Cover Block Signal? What You Need to Know

• Metal, magnetic, very thick, or radiation-protective covers can reduce phone signal by obstructing radio waves.
• Silicone, TPU, soft plastic, and original slim covers generally do not affect signal strength.
• Symptoms of signal reduction include fewer network bars, call drops, slow internet, and rapid battery drain.
• Test by comparing signal performance with and without the cover to identify if it's the cause.

Why It Matters: Some phone covers can reduce signal; choose silicone/TPU or original covers for best performance.
