Does this fix change the waterproof efficiency?

Sven Decker - Jun 27, 2016

Hello atilasilva,

I guess so. Since you have to either replace the complete back cover or at least the glue line around the back cover I think the phone will not be completely waterproof again. It still may be solid splash proof.

Thanks a lot. This instruction really helped me to replace the battery!

David444 - Jan 31, 2020

I am about to follow your procedures to do a battery replacement. I have read your instructions, one question is if any need to use some glues to fix the back panel of the Sony Phone? From your instruction you did not mention the use of any glue at all, I am a bit concerned because at the moment my Sony phone both front and back panes are already loosen. I was told this is due to the old battery expanding.

Thanks for your help
