Radio Problem? How to disable?

[towtox]

I have a Samsung GS2 Gt-i9000M, Rooted with superuser.

Anyways my phone was recently updated to 4.1.2 It has been doing this weird thing where the screen flickers and then shows a no signal icon in the status bar then it shuts off. I was looking around and read that rooting can help fix the issue, it didnt help. What I did find out is that right before it turns off an "app" called Radio comes up right as it turns off, I managed to block it and the phone stayed running for about 3 mins until it was overtaken by it. Now how do I disable this? and is it radio as in FM radio? or it is something used for finding signals. As well my battery spikes are crazy, I got from 90% to 0% when this happens and my phone will boot up until it is at the main screen then do this again. It happens at 60% daily and will usually only happen when on wifi or on data. Really frustrated considering doing a factory reset just scared of the idea of loosing all message logs and such. I also have been told it can be caused by the battery bulging, I would buy a new one yet to get one costs around 60$ with shipping (im up in Canada). Thanks!

In a cell phone context, "radio" usually means the part that connects to cell phone towers/service...not merely used for finding signals, it's responsible for all mobile connectivity. Whether that app is related to your actual radio or is something else I can only guess, but the correlation seems appropriate.

If you think the battery may be to blame, you could buy a cheap one on eBay. You should be able to find one at a reasonable price with reasonable shipping to your land, even if you don't expect it to last long at least it can tell you if an imperceptibly bulging battery is messing with your radio.

You could do a factory reset and use a backup app to save your message logs. I use GCloudBackup (see the the GCloudBackup bonus note in my sig), which backs up messages, call logs, contacts, photos, videos, music, system settings, browser data (looks like only the stock browser), and "documents" though I'm not sure exactly what files are included. Being rooted you could even manually back that stuff up if you can find it.
