Since JB 4.1.2, my Bionic has been performing really poorly. Not only my Bionic, but i've had Asurion send me 2 others since June 2013, because i figured it had to be an isolated problem- a bona fide defect. But, no. Even the subsequent refurbished units bogged down under normal use every day. I get delayed functions and reaction to presses of the finger. I have to go into Stock Recovery and set to wipe cache to get it to run smoothly again. But, that only lasts a few hours. I don't really see the point in continuing to trade garbage refurbished devices with Asurion any more. So, i now do this no less than twice per day as part of my daily routine. That doesn't include a few regular reboots peppered in there throughout the week. I'm really unhappy with what Verizon did to the Bionic with their 4.1.2 update. Additionally, i cannot understand how my wife's Droid RAZR M has the "same version" of JB installed on it and my BIONIC is lacking features that she has. For instance, we got Chromecast to play movies, etc from Android (and others) to the TV. Her RAZR M can cast movies from Google Play Movies & TV app, but the same app on my BIONIC doesn't have that cast icon displayed. I've read that this could be the fault of Google, but it seems odd. I can cast Play Music, and YouTube (Google apps), but not Play Movies & TV, or Netflix. Verizon has treated the Bionic, and Bionic owners as second class (if that) for quite a while now.
I would happily buy a new device, but without an upgrade due, anything comparable to what Bionic used to be considered [flagship] is way too expensive. Actually, any device without the subsidy of the 2 yr contract is ridiculously expensive. I have talked with VZW Customer service and sales reps, to no avail. They read the cue cards and further the impression that Verizon Wireless doesn't give a rip about current customers. They only want to draw in new customers.
After over 13 years as a Verizon Wireless customer, i'm seriously considering dumping them and going to a carrier that doesn't choke the customer experience to a barely tolerable scenario, predicated by throwing your money away on a device that you can count on being adversely affected by the painfully slow software upgrade process, in itself, offering gimmicks to cover up the damage it does to overall performance of the phone they suckered you in with 6 months earlier. The term update or upgrade used to mean a progressive iteration resulting in (at least- some) improvement.
JB 4.1.2 on Bionic was a mistake for Verizon, Motorola, Droid, Google; whoever caused it.
