That being said, it looks like Microsoft is trying to do something similar as well and have announced an update to its Skype messaging app, where in the latest update Microsoft has made the app optimized for lower-end Android handsets. “This update—starting to roll out in the next few days—is lighter on both disk and memory consumption, allowing for greater speed and better audio and video quality on lower end Android devices, as well as increased performance in challenging network conditions.”
According to Microsoft, this will be applicable to devices that are still running on Android 4.0.3 to Android 5.1, which are presumably older and thus less powerful compared to more modern Android handsets. The update is expected to be rolled out across the world over the course of the coming weeks, so if you do own an older/lower-end Android handset, then this is an update to Skype that could be worth looking forward to.
