The Lava Agni 3, unveiled last October, is due for a successor. The Indian handset maker hasn't announced the launch date of the Agni 4 yet, but it has teased the smartphone on its website, revealing that the Agni 4 is scheduled to arrive in November. The teaser shared by Lava confirms that the Agni 4 won't feature a secondary display on its rear, like its predecessor, Agni 3, and it will also have a different rear camera layout.
