If you want to save a lot, you can try to replace the screen by yourself. But it is hard job...
Share a Z1 repair guide with u. Hope it can help you.
Why does everyone say it is hard. It is really simple compared to other phones I took apart. It is all held by glue and just requires patience and some decent eye hand coordination. I replaced my Z1S screen in about 45mins while watching a youtube video on how to do it.
