1. I have the same problem. My last Zylo did the same thing last year, I assumed it had overheated and I bought a new PAYG one, exactly the same.
2. Today the replacement has just done the same thing; hence I have come here looking for help. Statistically the odds of the same thing happening twice are very low indeed unless it is a known common fault, which is astounding really; if it is a common known fault, they should have undertaken a recall as carmakers do.
3. I have just spent an hour and a half of my life downloading the service updater software, and software update, installed it on my phone, and it is still doing the same thing. It rumbles when I switch it on, the keypad backlights, but the screen doesn't come into life. Despite when I went through the software upgrade the screen lit up as it should do normally.
Not only is the phone software-hardware interface clearly inadequate and unreliable, but I would use the phrase built-in obsolescence in a certain context but I guess if I did the Sony Ericsson legal team would go to great lengths to explain that phrase wouldn't be applicable.
Worse still really is the brazen time-thievery of my wasting an hour and a half of my life on undertaking an unnecessary upgrade, which the Sony Ericsson technical people probably know is likely to be futile, but they hope engages and 'locks in' (to use the heart-warming language of marketing) the customer to staying with the brand, as they have 'invested' time with the product (again, notice the linguistic gymnastics involved in turning the word 'wasted' into 'invested').
It is a shame as the basic functionality is good. This repeat fault in a mainstream handset however, is not good at all. That and the frankly disingenuous advice which compounds the problem are more than enough to make me wave the brand goodbye.
