P.D. Sorry for my english
Hi @Mipagon, I am sorry to hear about that. 
Do I understand you correctly in that the back cover is no longer attached? I advice you to get in touch with your Local support in order to have the device sent to an authorized center, that way a technician can have a look at it.
Hi
Thank you very much.
i had the same problem... the battery was swollen so i poked a hole and let out all the pressure build up... but the battery never gave any problems......... i still got a whole day of normal use on about 50% 
@Mipagon I recommend to get in touch with your local support team regarding this so that they can look in to it for you. This is a Global used based forum so unfortunaly I can't assist you with a local service case since service routiens, consumer laws and warranty terms vary depending on the market.
Hi, I want to know if anybody has a problem like mine.
Regards
Did you enquire why you require a screen change if you think it is just the battery
if not contact them again but i am sure there is a perfectly good reason. With regards to anyone else having suffered the same problem...if you type in a combination of certain words regarding your issue into the Search bar i'm sure you will find some results......:smileysmileywink:
I agree with @dandy63s reply, it would be wise to get in touch with your local support to be assisted with this case since it is on a local level
Hi. I have the same issue since last week.
My Z2's rear panel was opened up (at 1 long edge and 1 short edge). I tried to push it back but failed. It seems like the battery which might be swelling has blocked me to push the panel back to its position. Since then, the battery life also degraded. I am a little worry if it was battery related issue (safety concern).
