Here are some of the issues I was having when I update OTA to this latest release.:- Rapid Battery drain Video not playing Music player taking ages to play track in shuffle mode. Media player not finding any media Picture viewer fragmenting picture Device becomming slow and laggy impromtu re-boots and many more minor irritations... I was beginning to dispair as the device was worse than the day in early december that i bought it. However excellent after advice on here I went to a re-flash. Wow, what a difference. Fast, no issues and battery seems to last for ages, even on wifi. Was a bit of hassle to re-flash as I could not get it to work with Win 7 64. It worked on Win 7 32 fine, the whole process including restore of data and apps was no more than 30mins. Well worth giving it a go.
