Hi all,
I own a I9100 and it's been working fine for over a year. I had the Supernexus ROM installed and everything was perfect. Last month I started experiencing random shutdowns, so I changed to Cyanogen... same result. Yesterday I restored a stock 4.0.3 ROM and same thing still happens.
These are the things worth noting, based on my experimentation:
1) Right before (2 seconds) the phone shuts down, I notice the cell bars are crossed out.
2) If during that I try to operate the phone, it shuts down
3) I was able to avoid the shutdown by letting it sit there. The bars eventually come up again and the phone continues to work
4) In general, the shutdown (or its cause) overheats the phone. I notice its warmer close to the camera lens. And also, after this happens, when I turn it back on it usually shuts down again almost immediately
5) In some of the times this happens, it's accompanied by a significant battery drain. I've seen it going from 70% to 1%, from 100% to 75%, and I've seen no drain at all. I've also seen apparent battery drains, and if I shut the phone down myself, and power it back up, the battery increased by itself (which looks like a measurement issue).
Any clues? Did anybody experience anything similar to this?
Thanks!
