Storage Windows Phone 8.1 for HTC 8s would solve all problems

Hi all,

seriuously I think the worst part of this phone is the memory. With only 3 apps installed (Whatsapp, Instagram BETA and a simple To-Do-List app) my memory is constantly full. It gets so bad sometimes that the phone only shows a black screen and the clock like this.

With being able to install apps (and hopefully the app data) on the SD-card the phone would be really great again.

Does anyone know how the chances of getting 8.1 for this old phone are?

  • ROM: ARHD 31.5
