Bro, any issues with condensation forming around the phone when mounted at air vent? My experience dated back to the day I had a toyota hilux, and at that time I was using I think it was a Nokia 6500. Anyway, hilux have those built in cup holders just in front of the ac vent. this was where I put my phone. Then one day I realised that it was fogging behind the lcd. Then I stopped doing that. Didn't know wheter that issue affected the phone or not as I sold it off after the incident. Those phones have removable batts, therefore there are air present. And I am sure the smartphones nowadays are not vacuum air tight.
