Sony Xperia Z4 is one of the most highly-anticipated smartphones yet to come after the release of iPhone 6, HTC M8 and Samsung S6. Sony was expected to showcase the phone at MWC 2015, and subsequently release it soon as Sony has a habit of launching a new handset every six months.
But these claims were declined by Sony, and the Z4 was a no-show at MWC 2015. According to Forbes, Sony may actually plan to exit the smart phone market based on a comment made by CEO Kazuo Hirai that Sony could not pursue sales growth in areas such as smartphones.
Other rumors state that the new Xperia Z4 is still in the works but it has been pushed back. The delay could also mean that the handset is presently not ready.
It can be assumed that Sony doesn't want to compete with the flagships of Samsung and HTC, so we believe the new Xperia Z4 will be launching in late summer or most probably in June. Another interesting rumor has been stating that Sony will be launching a walkman edition of the flagship Xperia Z4.
