Google broke telephony for many Nexus users
I work for a telco (I don't speak for them, usual disclaimers apply).Everyone gets really ranty when operators delay firmware updates.  Yeah, some of them delay to force you to buy a new phone, or to stuff the ROM full of bloatware.  Most, however, do extensive testing to make sure that customers don't ring up call centres making angry complaints.Carriers (by and large) test the phone to make sure that the network portion operates correctly.  They make sure that it complies with local regulations and that it's not going to interfere with the network.  They also test that basic cellular functionality works.  Many go further and check all standard operations of the handset.It's been several years since I was responsible for device testing, but here's a list of problems that I remember from big name manufacturers (Nokia, HTC, Sagem) on their "final" firmware.- 999/112/911 features not working.- Reboots when receiving a text starting with a 0.- Factory reset when receiving an MMS with more than one attachment.- Inability to switch from 3G to 2G on handover.- Caller ID always picking the first name from the SIM.It was, frankly, an unending parade of shoddy workmanship.  We'd file reports, wait for an updated firmware, test it again, see that it had more bugs, refuse to ship it.Frankly, a few "enthusiasts" whining that they don't have a 0.1 firmware upgrade is a sensible price to pay compared to millions of customers storming your shops and demanding refunds.Google has an atrocious attitude to customer service - it's part of their business model https://shkspr.mobi/blog/2013/02/googles-customer-contempt-c...
