Seems like the latest S20 FE 5G handset is plagued with a number of issues that are yet to be officially confirmed by Samsung.
These are (in my experience):
1. Touch screen ghost touching and poor response.
The phone exhibits poor response to multi touches and occasionally interprets single touch action as scroll and vise versa. Pinching to zoom (and holding) makes the image on the screen shake. Also swipe typing on the keyboard is very difficult.
2. Poor implementation of the proximity sensor - the screen does not always turn off when holding the phone next to the ear during a phone conversation causing the ear to press random buttons (occasionally putting the phone call on hold)
3. In pocket activation - the phone screen randomly activates in the pocket and starts dialing numbers.
NOTE: I've tried all troubleshooting steps you can imagine, including factory reset
Issue 1. is rather well documented and seems to be very widespread:
The new software "G781BXXU1ATJ1" with the October Security patch (Released in Europe not yet By Optus) does not (according to forum posts on Samsung support) address the problem. So given the lead time for Samsung to release the fix (if it's a software issue and not hardware one) and then the time for Optus to test the new firmware, we could be looking at 1-2 months of using a faulty device.
After speaking to Optus support the only solution I was presented with is to send the phone for repair, very frustrating considering it's a 1-week old device.
I've scrolled through the threads you've mentioned as well as the S20 FE 5G hardware fault mega thread up on reddit.
There’re a few users who’ve stated that they’d purchased the device from within AUS, but I couldn’t see any mention of a specific carrier.
The last weekly Optus device updates report we received doesn’t include the October patch from Samsung - G781BXXU1ATJ1.
As for the solution you were offered, it’s not something I’d suggest – at least not at this moment. As is always the case with hardware issues reported so soon after release, we’ll need to wait until we receive acknowledge from the manufacture.
Their investigation will reveal whether it’s a specific batch that’s impacted or if all batches are impacted. We’ll then work with the manufacture to provide a remedy.
I’m happy to raise the issue from my end. When we do hear back, I’ll update this thread. I encourage anyone else who's come across this thread and experiencing the same issue to leave a comment.
Disappointing that Samsung hasn't provided G781BXXU1ATJ5 which is actually meant to address the issue (although looks like it's a bit of hit and miss - https://www.reddit.com/r/Galaxy_S20/comments/jfgyr1/samsung_has_issued_a_touchscreen_issue_fix_for/?...
So we are at least a month away from "maybe" having this issue resolved in Australia
