I have the highest regard for Nokia Lumias. My wife and I had such great experiences with our past Nokias and we are also delighted with her Lumia 820 and my Lumia 520. It's time to upgrade but when I look at the 830 and 930 WPC reports I am stunned to read about the copious bugs. There is clearly a lack of quality control and WP10 is still very buggy too. MS needs to address these issues because general confidence is currently at a very low ebb. In Thailand there are 3 major network providers - AIS, True, DTAC. It is currently impossible to buy 830 and 930 Lumias from their online stores. Our local telephone shop has told us that these phones are not currently stocked anywhere in Thailand. Clearly the Thai network providers and phone suppliers are unwilling to risk customer dissatisfaction by supplying MS Windows phones. This is a crisis that MS needs to address urgently because once goodwill has gone, it takes years to recover. My wife and I will wait until we see great reviews of MS phones and great reviews of WP10. MS I beseech you, please improve your performance before it is too late!
