Now, I am sure that they have fixed lots of problems - but I am still finding that apps freeze occasionally, and sometimes just crash and take me back to the Home Screen. And I find my phone re-booting itself on a regular basis, when I least expect it to!
If you have already upgraded to version 8, I would definitely go ahead and install 8.1.
The question is whether it is time yet for those who are still no version 7 to 'take the plunge'.
If you are prepared to accept that the freezing and crashing might happen to you - and know how to deal with an app that has frozen and won't respond to any form of banging on the screen (and swearing!) - then go ahead and download now. The are many great new features that make such an upgrade definitely worthwhile, included that described by this week's Handy Hint.
If you are not so confident with dealing with mis-behaving apps and not 'chomping at the bit' for the new features, continue to hold back for now - and stay tuned for further advice on when the 'coast is clear'!
