A few weeks ago, my grandparents bought a budget camera from Temu to monitor their front door. However, it seems that the accompanying app, "Yi IoT", has infected my grandfather's phone with a persistent pop-up ads virus. The ads are overwhelming, showing up constantly, and even putting the phone in flight mode only reduces it to 1 or 2 ads per minute. Booting the phone into Safe Mode stops the ads completely. I've tried uninstalling the app, but the ads are still there. I ran scans with MalwareBytes and Bitdefender, but neither found any issues. I'm considering backing up his important data and doing a factory reset, but I'm hoping to find a solution before taking that step. His phone is a Samsung Galaxy A90 5G, and any help would be greatly appreciated!

Honestly, the bigger concern is the trustworthiness of the camera itself. If it came from an unknown source, it's better to just retire it to protect your grandfather's privacy. Consider getting a well-reviewed camera brand next time. Safety first!
Smart move! There's plenty of reliable tech out there. Just do some research before purchasing.
It sounds like a rogue app is still lingering if the ads persist after uninstalling. Have you checked for any other unfamiliar apps that might have sneaked in alongside? Sometimes, adware can be hidden in other downloads. Try clearing the cache of all apps as well, in addition to the browser. It can help eliminate any remnants.
That's a good idea! I would also recommend looking into any device administrator apps that might be controlling stuff in the background. Sometimes they can get the phone to display ads outside of regular apps.
Exactly! Also do a factory reset if you still can't get rid of them—it's the best way to make sure nothing is left.

I completely agree! The camera has already been thrown out. He's not very tech-savvy, so it’s good to keep him safe from dodgy tech.
