Earlier, we heard Samsung users having Lollipop issues with S5. The UK subsidiary has confirmed that it will soon rollout the micro updates to fix firmware woes. The branch has also revealed that it is working on the updates for other devices having the Lollipop issues.
This response was generated as result of a query on twitter which asked that S4 is also having issues with updates, whereby the reply stated micro updates will hopefully resolve all of them. But, no time or date for micro-updates roll out has been mentioned. Meanwhile, the Galaxy Core Prime has started receiving the Lollipop update in Poland.
