@darshwill @prashant2508 facing same problem with my website, bounce rate jumped from 55-59% to 95-100% overnight screenshot - https://drive.google.com/file/d/0B0QfWR_1c80HVzhoTnlia3FzR3M/view?usp=sharing
@christoph142 - there is an increase in bounce rate from UC Web browser too from 50% to 75%. But bounce rate is constant in chrome on android and UC Mini.
Bounce Rate by browsers
UC Web Browser - https://drive.google.com/file/d/0B0QfWR_1c80HR3ZybnYxMEZ6T2M/view?usp=sharing
Opera Mini - https://drive.google.com/file/d/0B0QfWR_1c80HdlQyY0lBZUFtZmc/view?usp=sharing
Couple of hypothesis:
Base GA code not firing:
There are certain ajax calls which we track as pageview have suddenly become landing pages. These ajax calls cannot simply be landing pages because base page's google analytics code should get fired first. So something is stopping base ga code from getting fired. We see that new version has the on/off switch but we are facing this issue in earlier versions like 7.5.33725.
What I can gather is, pageviews are getting converted into sessions, known fact - GA records - 1 PV/session as bounce and 2 PV/session as non-bounce. Why would subsequent pageviews be turned into sessions? Maybe something to do with Opera proxy-based architecture (https://dev.opera.com/articles/opera-mini-and-javascript/) subsiquent pageviews might be landing on different servers in the proxy farm. Refer to this image - https://dev.opera.com/articles/opera-mini-and-javascript/architecture.png
This behavior is exhibited on 1 of our websites. In all other websites bounce rate through mini is normal. Here is the link to the website in question if someone wants to help debug :

Page where discrepancy is highest - http://goo.gl/SkPLgn
Something to do with any javascript libraries?
We didn't make any deployments or code changes to our website in this period.Hope someone helps us debug this issue and resolve.
Thanks in advance!
