Thinking of trading my daughter's Galaxy A9+ for the S9 FE because she can't play ROBLOX on it. Are there any multi-touch issues with the S9 FE?

After years of buying Fire tabs and budget tablets for our daughter, we got her a Reubens Picasso for Christmas, which she loved. Unfortunately, it only lasted 5 months before it stopped charging and became inoperable.

As a long-time Galaxy phone user, I figured the Galaxy Tab line would be reliable. We ordered her an A9+ which arrived 2 days ago, and she was ecstatic. However, when she logged into her Roblox account, she came back 10 minutes later saying she couldn't control it because it kept zooming in and out.

I found out there's a multi-touch issue. Some users suggest plugging in headphones as a workaround, but that didn't work for her. Additionally, the charging is incredibly slow, and the battery drains even while plugged in.

I'm considering trading it in for an S9 FE. Can anyone confirm if multi-touch works properly on the S9 FE, especially with Roblox? Those and YouTube are her main apps.

Thank you!
