Smart phone help please: Currently have Android 5.1 on my phone

8. Use your outdated phone to call Pizza Hut.

The only reason this is even an issue is because Pizza Hut will not support 5.1 any more. I use their app occasionally. Now I can no longer use it on my phone.

Honestly, there is no way I would "update" my phone or buy a new phone primarily to communicate with Pizza Hut. If Pizza Hut no longer has phones, or no longer answers their phones, I would find some other place to get pizza.

PS: I just checked and I have Android 5.1. I'm thinking of getting a new battery so my MotoX can continue another 5 years or so.

PPS: I'm not a cheapskate or a Luddite. I just think that consumerism is bad for the planet. I accept that smartphones are necessary for a modern life, but I reject that people should get new planet-destroying gadgets for trivial reasons.
