My mom came to me with a problem with her phone about how these chinese characters keep popping up on her phone about every 5 minutes or so. I got a look at it and tried to take a screenshot of the characters when they would appear on her phone, but it seemed like it knew when I would try to take a picture of it because when I would try to take a picture of it, it would only show for a split second, while without trying to take a picture of it, it would be on screen for a few seconds. The characters on the phone showed up as follows: 账号SDK进入测试环境 After I was finally able to get a shot of the characters by taking a video, I thought I found the source of what was happening in her file manager and deleted all the files that had SDK in them. 5 minutes later, she is still having the same problem, and I am wondering how I can make this go away. Has anybody else had this problem, or is it something specifically that my mom may have on her phone?

Are you sure that it’s not someone sending her an emoji or a facebook messenger sticker?

Same strange problem, have you found out what’s it’s all about?

How about trying this folks. I had this problem once upon a time too. That page is full of ads so basically go to settings,. Apps, then remove or disable any chinese apps. Also disallow notifications from them. That doesn’twork also clear the cache. Enjoy.
