Xperia strange bulk
It has come to me. XPERIA as a kind of bulge from the inside out, on the back of the phone, rather in the area above .. The phone works perfectly, can it be the battery? It's a hard bulge, ses rarisimo .. I'm afraid it's the battery and it explodes or something.

Xperia bulto extraño

Le ha salido a mi. XPERIA como una especie de bulto de dentro hacia afuera , por la parte de atras del teléfono, más bien por la zona de arriba..El teléfono funciona perfectamente, puede ser la batería ? Es un bulto duro, ses rarisimo..Me da miedo que sea la batería y explote o algo.

You should STOP using the phone ASAP, that's most likely the battery, perhaps the phone was exposed to water or got damaged, you should contact your Local Support ASAP
