I have seen a few other posts surrounding this issue (all quite old now) and through some testing found this bug out:
In system settings > Touch > General use (select touch off): and this works great, but the minute the watch enters sleep mode at your set time (or if you do it manually), the touch screen activates again??? It is really frustrating. An option for touch screen being off in sleep mode only would be great, but this doesn't exist. I thought I had to endure no touch screen all the time to ensure it is off for sleep mode but it reactivates, so now instead it's off in the day and on in the night?
Please can someone help me if there is a setting, or raise it as a bug if possible. Thank you
