I know that this might not be the most constructive feedback, but I am getting really frustrated with my NP3900 (and NP3700).
I bought both players in November to have a nice radio for the kitchen and one for the bedroom. They had to fulfill the "wife acceptance factor" - i.e. look nice and be easy to handle. All good so far. Especially the physical remote control turned out to be great. We are hardly using the touch screen or the Android app.
But now the negative impressions start to pile up - and got so bad with the recent firmware update to the NP3900 that is it not acceptable anymore:
- Features for NP3700 and NP3900 are actually different. One can dim the display after a time out, one cannot. I clearly did not expect that as the players where released as one series esp. for such simple features.
- We like to keep the devices in sleep mode, but they seem to have problems with the wifi connection when they come out of sleep, so a hard-restart is required *sometimes*
- The Internet Radio for NP3900 crashes after a few minutes or might go on for hours *sometimes* (just to ensure you, the general Wifi is stable for all other devices in the household)
- If I use the Android Remote, it works with a fresh start of the app. If I later start the app again, it does not work and I have to kill the task (on Samsung Galaxy S with 2.3.5 firmware)
- The Wifi signal for NP3900 is *much worse* than for NP3700. We switched players between kitchen and bedroom when problems started
- After the recent firmware update, the NP3900 sometimes even gets stuck in sleep mode: the clock is displayed in standby - the time shown was 10 am while it was actually 3 pm. Only pulling the power cable allowed a restart!
- That the NP3900 completely freezes (while playing Internet Radio or while in standby) and only pulling the power cable helps. This happened to me three times in one week since the firmware update.
What I am saying is that the hardware of these products seems to be very nice.
However, the quality of the software is the worst, I have experienced in consumer products and actually makes me reconsider my planned purchase of a new Philips TV. As said, it is not just a specific issue, but rather the overall stability of the devices.
Philips, please look into your quality assurance processes and release new firmware more often with a clear transparent schedule. And if you are not good enough at software development, consider sponsoring an Open Source project like Logitech does with the Squeezebox series.
