I have an LG G2. Lollipop damaged my phone and I got the run around. Verizon blamed LG. LG blamed Google. Google blamed Verizon. I recorded all conversations. I went back to Verizon with all my recordings and they admitted they forced the update. I even called Verizon before it installed to specifically request that my phone not receive the update. Eventually Verizon forces the update onto their subscriber phones without your approval. I have this admission recorded as well. You can secretly record depending on the state you are calling for customer service. Try to find out what state you are calling before recording.
My device had unfixable problems immediately after Verizon forced update. Verizon sent a refurbished phone to replace but I had a ton of apps and data that needed to be restored/ transferred over. Verizon claimed no additional liability after replacing my phone. I took Verizon to small claims court because all limitations on liability and mode of legal action in customer agreement are out the window because forcing an update on my device is not part of the subscriber agreement. Court agreed no limitation on liability and awarded an extra $490 plus prevailing party fee and court costs for $715 total. Verizon paid the judgment about 6 weeks later. If you do not voluntarily install update, keep this in mind. If I had it to do over, I would have gone straight to court and rolled the cost of the phone into my damage claim instead of accepting Verizon's refurbished phone. Verizon's only defense is that the customer agreement limits liability. They repeated this over and over. Keep in mind this is their interpretation and is not the correct interpretation.
Don't let them be reckless with YOUR DEVICE without consequences or they will just keep screwing us.
