Those problems are not normal. The DX170 is very slow and the user experience suffers for this reason. But otherwise, apps don't usually crash, it doesn't get that hot, and the battery doesn't last 1.5 hours.I just use my DX 170 without internet with the Wi-Fi and blue-tooth selected off, listening to my music on the 1tb SanDisk micro SD card which are all mp3 and MP4 music files, but the player still gets really hot to the touch, battery is draining really fast with this new firmware, only getting an hour and half before I need to recharge it again. User experience is very sluggish and I only have 2 apps installed the native music app and Poweramp, the 2 apps I have crashes, sometimes I can't even select a track because the player doesn't respond to my finger presses because it is so sluggish, it's not a very good user experience, please fix these issues @Paul - iBasso
Your unit must have a problem, definitely.
