Depending on what phone you have it may be worth investing in either a skin for your phone or tempered glass screen protection. preferably both for the best all round protection without adding bulk or covering the phone in rubber. of course not dropping your phone is the best solution (lol) but I understand that is easier for some than others. companies that do skins are D-brand or slickwraps, but there are others too with more options. Skins are really the best way to go if you do not want a case/bulk on your phone. Tempered Glass is like a glass screen protector but usually tougher than standard screen protectors. they absorb the impact of falls and most likely crack or shatter. but it means your actual screen is safe and undamaged.
