I have been getting the same robot voice and redirect to the play store on Galaxy S8+/Chrome for about 3 weeks id say. I thought it was an isolated NT thing, then I got it while on another site in chrome.
Just today my mother in law started hearing and she had heard it on my phone before when she was looking at it. She called me today to ask how to clear out her history and such. She called from another phone and i heard in the background her phone did the same robot voice thing (she aint on NT )
She cant remember if she used chrome or samsung internet, im thinking chrome but either way something is going around
I get that robot voice about 2-3x a day. I googled it and people's diagnosis' are all over the place. I think it may be chrome based
The voice says: "Warning your device is running critically low on memory. Please update/use android cleaner" - redirects to google play store
Other says: "Warning your device is running (cant remember) Please update your android media player" - redirects to google play store
I was getting the same pop up at least once a day but I haven't had it once since I stopped using Chrome
