The screen of my xperia is off (on the left top)

[Jonjonander]

Anyone know what to do about it?
Is taking off the screen from the left top

How can I lock so it does not take off?

Thank you so much
Jon

If you want to DIY, you will have to take the whole phone apart and repalce both double sided tape, one for the back pannel and one for the front pannel.

Hi Jonjonander,

I don't quite understand the question, are you saying the screen is damaged in some way, or is this related to the touch screen or are you having issues with the display with pixels?

Sorry for the inconvenience.
