Buenas tardes. Quería externar mi inquietud. El xperia XA ultra. Esta dando problemas de pantalla. El primero que me dieron en la compañía telefónica al mes. La pantalla de la nada empezó a vibrar y con un montón de rayas en las 3 primeras partes del cel. Le cambiaron el software y siguió igual. Lo volvieron a mandar a Sony y siguió igual. Me cambiaron el cel x otro Sony xperia XA ultra. Y solo lo he tenido por 3 meses y ya esta igual pero este es en toda la pantalla. Rayas blancas. El software está actualizado de fabrica de Sony. Al guíen me podría decir que hacer. Xq ya no se que hacer con estos teléfonos. Sera que es un defecto de fabrica. Agradecería sus comentarios.
Good afternoon. I wanted to express my concern. The xperia XA ultra. This is giving screen problems. The first one they gave me at the telephone company a month. The screen of nothingness began to vibrate and with a lot of streaks in the first 3 parts of the cel. They changed the software and stayed the same. They sent it back to Sony and it stayed the same. I changed the cel x another Sony xperia XA ultra. And I've only had it for 3 months and it's the same but this is on the whole screen. White stripes. The software is factory updated from Sony. The guide could tell me what to do. Xq I do not know what to do with these phones anymore. It will be a factory default. I would appreciate your comments.

Hi @40-julioCesar,
Please note that your previous post has been translated in to English using Google Translate as this is a international community. If you could keep your future posts in English that would be great as it makes it easier for other users to read and understand. 
I'm very sorry to hear this. 
I recommend that you perform a software repair using Xperia Companion to make sure that there is nothing software related causing this behavior. If you are still experiencing the same behavior with your devices display I would recommend that you get in contact with your Local support team for assistance to have your device sent in to an authorized service center for further troubleshooting and repair.
Let me know how it works out.
