Sony starts rolling out Android 9 Pie for Xperia XA2/XA2 Ultra, but you should avoid it
Xperia XA2 and XA2 Ultra phones could potentially make them unusable. XDA Developers reports that many users have had their phones bricked after installing the update in Russia, Belarus, and Kazakhstan.
Although not all those who install the update have had this unfortunate issue, those who did haven't been able to recover their phones using the Sony Companion software. What's worse is that there's no workaround to the problem, which is why we're advising all Xperia XA2 and Xperia XA2 Ultra to avoid installing the update for the moment.
We have no idea why Sony hasn't pulled the update yet, but we hope its engineers will be able to reverse the issue and allow Xperia XA2/XA2 Ultra users to recover their bricked phones.
