A small number of Samsung phones have been sending random photos to their contacts.
Reddit users have complained their Samsung phones, some being the latest Galaxy Note 8 and Galaxy S9 models, have been playing up.
The photos were sent through the phone's stock text message app, but there is no record the photos were sent from the affected users' phone, Gizmodo reports.
According to reports the bizarre action is due to a peculiar interaction between Samsung Messages and a recent Rich Communications Services (RCS) profile update that has been rolled out.
The goal of RCS is to update out-of-date SMS protocol such as read receipts, better media sharing and typing indicators.
Samsung said in a statement to Gizmodo, "We are aware of the reports regarding this matter and our technical teams are looking into it. Concerned customers are encouraged to contact us directly at 1-800-SAMSUNG."
