MWC 2026 kicks off today, running from March 2 through March 5, but announcements were pouring in all weekend in the lead-up to its official start.

In addition to the announcements, MWC is our chance to get hands-on time with some of the most interesting new devices, like the Xiaomi 17 Ultra and Honor's Robot Phone, and concepts like the Legion Go Fold.
All package pins measured plausible resistances to ground (a few hundred kΩ leakage measured with a Fluke 87V) as long as I had my microscope illuminator turned off. There was a strong photoelectric effect evident and I actually measured negative resistance on some pins with the LED ring light shining on the controller die. But this suggested that of the six bond wires, the ones going to the package pins were likely intact. By elimination, those going to the quartz crystal became my top suspects.
