A repost of what I posted
earlier today, but I think this thread is more fitting.
2 days ago I started to understanding the importance of the "Software" app.
I received 3 "system updates" in a row, and a reboot was needed each time.
Now I notice my phone became suddenly much smoother than what it was before these updates.
And I didn't notice any double tap problems since then too.
On top of that, it seems to be surviving a bit longer without a charger now, I had it off-charger all morning and on idle, and it's still on 85% battery.
Before that, it'd be dead by now.
However, it seems to suddenly restart the UI after pressing the power button once, and then it'll go into the endless login loop.
