A suicide note has been recovered from her house and the woman was apparently depressed over her marriage plans with her lover getting "slowed down", they said.
Following the incident on Sunday, police booked her lover for abetting of suicide on a complaint by the woman's family, they said.
"As per preliminary investigation, the woman had made a selfie video recording from her mobile on Sunday (February 7) before resorting to the extreme step," said Kavali police station sub-inspector Shaik Anwar.
The woman's mother was not present in the house when the incident occurred, he said.
"Her mother noticed the door of the house closed after she returned. From one window she saw her daughter's body hanging," Mr Anwar added.
The woman's mobile phone having the purported video was recovered yesterday.
"It was on Monday after their relatives came to the house that they saw the selfie video of the woman from her cell phone wherein she is seen appealing her lover to visit her once after her death.
"Bhanu... bring bangles and also kumkum (vermilion) when you come to see my body," the woman is purportedly seen saying in Telugu in the video.
"The woman and Bhanu Teja, an employee at a private company, were in love since 2014, but recently there was some gap between them after the woman sought to marry him.
However, the exact reasons are being verified," the police officer said.
The woman's mother lodged a complaint with police yesterday after which a case under section 174 of CrPc (ordering inquest) was filed.
The family members of the woman later accused Bhanu Teja of abetting the suicide, following which the case was altered to section 306 (abetment of suicide) of IPC, police said.
No one has been arrested so far, the officer said.
