Dear Samsung (s22, Ultra) users,

Since yesterday I am experiencing the same problem with my S22 Ultra 512GB, and I was so stressed. My phone was continuesly rebooting, and I could not start my phone anymore. I haven't had anything back-upped which made everything even worse. I could almost kill myself (not literally), and was feeling so bad knowing that all my pictures were gone.

But, I was looking through different forums and couldn't really find a solution. My phone is still under warranty, so I was so close to handing my phone to the Samsung dealer untill my phone was finally working for longer than 20 minutes. That made me interested. Why is it working now?

Here in the Netherlands it is really cold outside (4 degrees celsius), and I could link that information to one comment that someone gave on a forum about keeping the phone in the freezer. Now that I have placed my laptop and phone outside (in cold temperatures), I was finally able to back-up my files again. And I have to say, it works.

I think this updated created software that is too powerfull for this hardware, which created overheating for the components (CPU especially). For what I have found, not everyone is experiencing this problem. So for the people that have been hit by this constant rebooting problem, the CPU might need a reballing (to be able to work again for the long term).

and for the short term, if you are just like me, put the phone in a cold, (really) cold environment to be able to make a back-up of all your digital belongings so that the CPU can function again without overheating. I hope I am the first one that can make a change, and help people to save their photos and files!

This is also a lesson for myself to always, or regularly backup my stuff. For now, this is what I can share with everyone from my experience. Personally I am going to factory reset my phone after everything is backed up, and get the motherboard replaced. Because that is the main issue right now.

Hope my phone works well again after that!
