If you have an older Samsung Galaxy smartphone, you may want to hold off on the latest software update. 9to5Google reported that the update that has been rolling out from Samsung over the past few days is bricking devices from the Galaxy S10 and Galaxy Note 10 series of phones.

Samsung has now confirmed the feared bad news for millions of Galaxy users, as they fall further and further behind Google’s Pixel and other Android devices, to say nothing of Apple’s iPhone, its arch rival in the premium smartphone category. For those who have paid $1000-plus for a new flagship, this will come as a nasty surprise.
