Hello,
I am having few problems regarding windows phone update 7.8... I have nokia lumia 800 and i gave my phone to nokia care to update my phone software.. I live in India and i want to share some issues regarding update..
1) My home screen has lags while scrolling but applist works perfectly with kinect scrolling without any lag at all...
2) Some apps crashes by itself... random apps and random crashes so can't figure out what causes the crash..
3) Multi-tasking dont work anymore... during pressing and holding back button nothing happens...
4) Ringtone maker dont serach songs from my library after first search... so if i add new songs it wont appear in
ringtonemaker list... And it only allows to create from first minute of song so i cant create in between of song..
5) Kids corner is not there as microsoft said that it will be available in update...
6) While bluetooth sharing only mp3 files and images works... video files are recieved but can not be played...

What good is the new homescreen with resize tiles, ability to transfer files through bluetooth and bing wallpapers to set as lockscreen wallpaper and more colors for windows theme...

May be microsoft will keep this in mind and solve this issues in next update...

3 times now I have ended up stuck in the "plug phone into the computer" splash screen with no way to make it go away. This last time it kicked off a restore and I lost 45 days worth of data, history and pictures. Plus I had a time sensitive call I could not make and lost a business deal. I cannot tell you the level of anger and frustration I had at that moment. I love my phone, but if it ever does that again I will get an iPhone and never look back. YOU MUST GIVE THE USER THE OPTION TO CANCEL OUT OF THAT UPDATE/ LOW BATTERY SCREEN!!!!!
