I have been getting the "Internal phone storage is getting low" message for the past few weeks on my 7-month-old S2. I have already uninstalled all my non-essential apps, and only have a handful of small apps left, the largest being Twitter which is only about 13MB. But without doing anything, the internal storage of my phone just went down by about 15MB in one day. I'm now at 188MB of free space left.
I noticed that when that happens, my battery drains faster than usual and takes longer to recharge (it took 4 hours to get from 70% to 100% yesterday). During charging, the phone also gets very hot.
I also noticed that the Wifi upload traffic increases by about 100 to 200MB in a day even when I have not been using Wifi, according to my Traffic Monitor app. I did a google search on the low internal storage problem and found that some people mentioned there is a Wifi error log that keeps increasing in size and eating up the internal storage space. But to know if this is the root cause, I need to root my phone to access /data.
I'm seriously considering rooting my phone because I'm running out of things to delete and soon, I won't have any more free space left. But as a new Android user, I'm apprehensive of the rooting process because what I've found looks complicated. Can anyone recommend any guides for rooting that is up-to-date and also easy to understand? Unless someone has an idea of what is causing my internal storage problem so I won't have to resort to rooting?
Anyway, my phone's information is as follows:
