According to a Mar. 2008 meta-analysis of cell phone studies there is a "consistent pattern" connecting cell phone use and an increased risk of developing glioma, a type of brain tumor.  A Mar. 31, 2009 study found that long term cell phone use (10 years +) "approximately doubles the risk" of being diagnosed with glioma on the same side of the head where the cell phone is held.  In Apr. 2013 another study of Swedish cell phone users also found an association between cell phone use and the development of glioma and acoustic neuroma - a benign tumor formation on the nerve near the ear.  That study’s conclusions were confirmed by a different study in Apr. 2014.  Other studies published from 2005-2013 have similarly concluded that there is an association between cell phone use and increased risk of developing brain and head tumors.    
This is a powerful tool when troubleshooting an Android as it allows you to rule out poorly written, malfunctioning, or troublesome applications as possible causes. If you have a bad app or have installed a bad update for an app and your phone stops responding properly or starts having issues then you could put your phone into Safe Mode, uninstall that bad app, take your phone out of Safe Mode and be good to go, which actually brings us to our next objective, how to turn on Safe Mode and how to take your cell phone out of Safe Mode.

In September 2014, Californian oncologists reported four similar case histories of young women who had developed breast cancer in precisely the areas where they normally carried their smartphones. What shocked the doctors was that these women were aged 21 to 39 and had no family history or other risk factors relating to cancer. All their cancers “had striking similarity, all tumours were hormone positive… (with) an extensive intraductal component and… near-identical morphology.” (CaseRepMed., 2013).
