¿Por qué mi pantalla se enciende sola?

Tengo un problema con la pantalla de mi teléfono que se enciende arbitrariamente. Ha estado sucediendo por un tiempo, pero finalmente tengo un logcat de ella, así que aquí está. Si alguien puede encontrar algo aquí que parece que está causando el problema, y cómo resolverlo, por favor hágamelo saber.

Me resulta especialmente sospechosa la primera entrada de 10-01 18:25:44.411 y las otras entradas que dicen E/power pero no sé qué hacer con el resto.

ACTUALIZACIÓN

Parece que el tema del Galaxy S es lo que estaba causando los problemas. Por suerte, no era una aplicación de stock, sino una que descargué, así que la desinstalé. Por ahora, me reservo mi aceptación durante unos días para estar seguro de que ha dejado de suceder.
