Baidu spyware found on a few Sony Xperia devices running KitKat firmware

Do you remember Xiaomi controversy where it was said that Mi3 was allegedly sending some data to Chinese servers and which was later explained by the Xiaomi officials; a very similar kind of case has been spotted on Sony Xperia devices. It is being found that a few Xperia handsets running android 4.4.2 and android 4.4.4 KitKat firmware have a folder named “baidu” in their internal memory which is not associated with any app and can’t be deleted.

It is believed that the issue is associated with the “myXperia” app which is a similar kind of service just like Android Device Manager. As soon as myXperia app is activated the folder is spotted in the device internal storage. The folder can’t be deleted as it is appearing again in the storage.

Possible Explanation of whole Issue and how to remove the Baidu folder ?

A user Radeon962 from OnePlus forums explains the issue as :

NOTE : It is spotted that even HTC One M8, Nexus 5, OPO handsets also have similar kind of “baidu” folder on their device. Some users are saying that it is happening due to some launcher but some don’t agree to it.

We have tweeted to Sony about this matter, looking for a response now.


This is a very serious matter and Sony has to respond officially over this matter, we are hoping the company will come up with a proper satisfying answer. Collecting user data without permission is very unwanted and unethical.
