Don't really know how many people could be affected by this, but I figure it could be part of a new, bigger problem that may affect more people, eventually. So, I get my nice new White Lumia 920 and, of course, I'm in Nokia Heaven. Then we go on a four hour road trip and many times on these trips we will use our ac to dc inverter to run our wall chargers for our devices (for literally a decade).
Halfway to our destination (FSU Prism Concert), I noticed that the scrolling on my Lumia 920 was fragmented and lagging. So, I started disabling services, blocking background apps, turning off radios and uninstalling recently installed apps and none of this helped. Then I hard reset. Still the same, even after repeating all of the disabling. So had to use the Lumia 900 to record portions of the event we attended because when I tried hard resetting, again, I got the lightning bolt of near death and left the 920 in the car. Wife loaded the firmware image back on the phone on the way back home and the same stuff!!!.
So, we got home and when I got out of the car it acted fine! Very weird! So I tweeted NokiaCare and all of us had no clue. One NokiaCare person asked if I had blocked all of the background apps and I answered yes, but I figured they must have had a reason for asking that so I blocked all the background apps, got in the car, plugged the 920 in to the cig lighter USB plug and works fine! So, I apologized profusely to the NokiaCare people and, just to make sure, I drove around a little to make sure it wasn't something to do with movement. This time, when I got in the car, I grabbed a cord that was plugged in to a strip powered by the inverter. OMG! There it was! The same fragmented, lagging scrolling!
Ok, so now I try different brands of ac to USB adapters and all the same. The only thing I haven't tried is a different brand of inverter. But, wow! How bizarre! I hope Nokia and Microsoft are looking because I do believe its worth checking in to in case it's a new technology that could have overlooked having power supplied by an inverter. More and more cars are being produced with built-in inverters and this could interfere, eventually, on a broader basis. Has anybody else experienced this issue? You're welcome, Nokia, for all the research!
