Is it dangerous to upgrade iOS and Android?

[673]

Hi. I have an iPad Air, a samsung smartphone and a laptop with samsung kies. My iPad is running iOS 7.0.6, but my phone is on ice-cream sandwich. I want to upgrade my phone to Android kitkat using samsung kies, but i got to know two years ago that if the internet disconnects during upgrade or power goes out, your phone will be permanently damaged beyond repair. I live in Pakistan, so power outages and internet connection problems are extremely common here (I know I can use my Laptop battery if the power goes out). So is it safe to upgrade? Also, if there's a danger of upgrading my phone, is it also dangerous to upgrade my iPad? And if I DO need an upgrade sooner or later for my phone or iPad, what steps should I take before and during the upgrade? Thanks, ten points for best answer.

If it's provided by your carrier, then most of the bugs have been fixed and are considered official releases, and are configured for your device. As with anything, it's better to have a backup of your data beforehand.

I'm not sure how iOS upgrades work, so I can't really help on that, sorry.

As far as with Samsung-branded Android devices, you can actually download a firmware image file onto your computer (so even if you have outages later, you know you have the firmware file), then flash the firmware using ODIN (you can access the ODIN download mode by pressing Home+Volume Up button on startup before the boot screen).

But with either method, you're still vulnerable to outages. The only thing I would say if you really want to, consider investing in a UPS (uninterruptible power supply) system to keep your stuff running for an extra amount of time. (unless if you don't mind rooting your Samsung-branded Android device and installing a recovery image, then you can actually download the ROM image onto a external SD card and boot into recovery, then the phone will automatically install it itself without having to rely on a Internet connection or a dedicated power supply, unless if your battery is not charged enough).

No it would not be dangerous to update the software on devices you have. In fact it is recommended
