Galaxy A3 (2016) charging bug fixed by latest maintenance update
Samsung has started rolling out a much-needed maintenance update for the Galaxy A3 (2016) and Galaxy A5 (2016) in Europe, which fixes an issue that prevented the former from charging beyond 87 percent and transports a patch for a frustrating “IMS Service Stopped” bug that was affecting both handsets in the Netherlands.
We don’t know what caused the glitch
It’s unclear why exactly the Galaxy A3 (2016) was unable to charge to its maximum capacity, though many online publications believe the glitch was caused by a faulty line of code in a recent update the device received that was designed to patch the nasty BlueBorne security vulnerability (more on that here).
If you’d like to check to see if the update is ready for your Galaxy A3 (2016) or Galaxy A5 (2016)—A310FXXU3CQI8 and A510FXXU4CQI9, respectively—all you need to do is open up Settings, select Software Update, then tap Download Updates Manually. You can, however, wait until you receive an alert instructing you to install the upgrade.
