I was taking a shower; the Lumia 900 on the bathroom counter like I've always had my iPhone 3G. I got a call, dried off, used it, and the buttons on the phone became frozen and all touch input was no longer working. I finally soft reset the device by holding down the power button for 15 seconds (ignore the pull down to shut down tile, you can't drag it) and reset and it works again, but I am concerned. A little bit of humidity seems to have knocked it out, but it may be a coincidence.
Has anyone else experienced issues with touch not working with the 900?
Hey, I JUST - as in five seconds ago - had this issue. I was just at a concert, it was quite warm, and I'm sure some moisture got in/on it. Anyhow...
I tried everything I could, in the end running the battery down (which wasn't hard, as I had killed it pretty hard all day) and restarting it worked, All better.
Kind of weird, and I wish there were a way (I don't know of one) to restart the phone with just the buttons.
Anyway, run it down, and restart. Worked for me.
I experienced it twice with my Lumia 900. The first time I was charging it at home and when I was checking something on it, touch stopped responding. The second time it was in car when I was using Internet radio. The second time it was rather hot - around 80 F (and TuneIn tends to make 900 hot) but dry. The first time it happened under normal conditions (72 F, normal humidity). I noticed that both times battery icon became one with question mark.
Thanks for soft reset tip, I didn't know you can reset it by holding down power button. I guess I managed to do the first time but didn't realized I did it (I was trying to get it back on track by plugging and unplugging charging cord).
