LG’s QuickMemo is coming to its L7, L5, and L3 phones as part of a maintenance update, the company announced today. QuickMemo is a system-wide note taking service that lets users quickly annotate screenshots with handwritten notes and sketches. The annotated screenshots can then be shared, either by email or MMS, or by posting to services like Twitter and Facebook through LG’s Social+ interface. The company says that while the update is already rolling out in some regions, it will be available on all of its L-Series phones worldwide by the end of Q3.
