Hot Screen WarningTips

    Just a warning for everybody living in hot climate.

    Today I had a very strange issue that led me to believe that the phone was defective.

    I am in a part of the world with very hot weather - 40C on a daily basis. I went outside and walked around and took the phone out of my pocket at some point, only to find out that I was unable to unlock the screen. It was totally unresponsive. Even when I long-pressed the power button and the menu showed up to allow to power off, restart etc., I was unable to choose any of the options. After many tries I unlocked it, rebooted several times, defrosted all apps, uninstalled the most recent ones cleared cache, etc. Nothing helped. I was sure that the firmware was screwed up and backed up my stuff and did a hard reset. The issue persisted. I then returned to my office, put the phone on charger and let it stay in an air-conditioned room. After 15 minutes the issue was gone and has not come back since.

    I assume it was the heat as I restored everything from before the problem started and nothing caused it again.

    Hot climate + phone = bad times
    Not only does fhe phone overheat but it becomes unresponsive also if the phone becomes too hot it can cause internal damage

    The funny thing was, battery temp was only shown as 40C, that is not hot enough to break anything in the phone.

    I only assume it was the temperature, as the phone has been re-set up and has not shown the same problem since.

    If you live in the dessert, there is no way of avoiding hot temps :)

    I work at a place that does not allow cell phones at work. This summer when I still had my Inc 2 I left it in the glove box while I was at work. When I got off work I pulled the phone out of the glove box and it would not turn on. After running the car's AC for a while the phone finally powered on but my battery as at less that 10%. It was turned off while in the glove box. After this experience I no longer leave my phone in the glove box.

    I would suggest that more specifically, hot climate + weak signal = bad times. If charging or using GPS at same time, yikes.

    The ambient temp is a huge factor. My G3 was at over 49c yesterday, but it was hot in the car that I left it sitting for 20 minutes (windows open). That was the first time I noticed it get that hot, but I was in weak signal area where the GS3 gets very warm to hot, without a hot ambient temp.

    Other phones get hot too, so not just the GS3 having spikes like this.

    do you have a separate trunk? the trunk of a car usually stays much cooler than the cabin

    yeah, heat drains batteries quickly
