We had a very efficient and funny campaign to inform the general public that screenshots are not memes. However, people keep posting screenshots in this community. I propose that we establish a rule banning screenshots. Maybe there is a dedicated community or screenshots enthusiasts could create one. Of course if this proposal is widely opposed, I will withdraw it and go hide in a cave, never to be heard again. Also, cartoons are not memes either but this is a battle for another day.
Edit: added brackets to the title for clarity
Um… I think you might have malware on your phone. I’ve literally never seen an actual ad inside a default gallery app in any smartphone I ever had, including budget phones. I did a search on Galaxy S9 and anything about ads but all I could find is people finding out their phone is infected from malware after being advised to scan their phone by commenters. Can you post an image of the ad?
Also you might wanna run a malware scan. Malwarebytes is said to be reputable.
Edit: Do you used pirated apps? No judgement, just curious. Pirated apps are one of the common ways to get infected.
