Messaging app problem after lollipop update

[Ashhabah]

Sup guys ,

after I updated my Z1 to Lollipop a weird problem occured .

whenever I try to delete a conversation it get stuck at this screen fit too long almost 2 minutes , even if it has only one message inside ,

Any ideas ?
Thanks in advance

Could you let history eraser work for a longer time without force closing it? Even if you get a message where you can choose to close the app, just let it work for a longer time (for example during the night) and hopefully this can help.

Otherwise, I think a factory reset is needed in this case which will delete all the messages.

Ok Hampus I even did a factory reset . messages 

conversations got deleted smoothely , but whe I restored the old messages the problem occured again .

does this mean the conversations a bit too much

Then it sounds like it is a bit to many conversations/messages if it worked smoothly after the reset but not when you restored all the text messages.

OK then I will try to bear with it , although this problem didn't happen with kikat

Thank you very much
