On my Samsung Galaxy S6 (Android 6.0.1), sometimes the back button starts firing by itself, hence closing the current app or going back on a page. Sometimes this happens in bursts, making the device unusable.

As reported here and here it's a common problem. Users report as possible causes:

1. Device overheating

2. Use of data connection (perhaps causing #1)

3. Hardware problem (interference from speakers on the capacitive touchscreen)

4. Moisture (triggering false contacts on the capacitive touchscreen)

In my case, I've noticed it happening especially when I use the Twitter app, which makes large use of the phone capabilities. Running Smart Manager and closing all running apps sometimes solves the issue, so it might really be #1.

A factory reset does not solve the problem. Users suggest as possible workarounds, related to the causes above:

1. Let device cool down

2. Disable data connection

3. Lower volume speakers to less than 75% (?)

Anyone found a definitive fix for it?

On my Samsung Galaxy S6 (Android 6.0.1), sometimes the back button starts firing by itself, hence closing the current app or going back on a page. Other times it's like a ghost press on other parts of the screen, so that e.g. the menu opens by itself. Often this happens in bursts, making the device unusable.

It's a common problem, as seen here:

Users suggest possible solution (none of which are working):

1. Factory reset and/or cache reset

2. Let device cool down

3. Disable data and/or WiFi connection

4. Lower volume speakers to less than 75% (?)

5. Dial *#2663# and do a TSP FW Update (General)

I've had this happen to me on 2016 (hence the post), then the problem disappeared by itself, now in 2019 it's back, more annoying than ever.
