Application mutes battery full charged notification sound and vibration for Samsung Galaxy S2 GT-I9100 and Samsung Galaxy Tab 10.1 GT7510. Application may start work correctly after first or second charging when it self calibrates! Note: If you set Mute From=23:00 Mute To=7:00 it does not mean that notification sounds are muted during this time from 23:00 to 7:00, it means that program mutes sounds within this interval. Notification sounds are muted when battery is at (usually) 99% and notification sounds are restored after full charge. Program mutes notification sounds for couple of minutes. Description: Mutes notification stream sounds and vibration (vibration feature works only for some phones) just before battery is fully charged and restores volume after battery is fully charged. It is possible to configure time range when feature will mute notification sound (within this interval notification sound will be muted just before battery is going to be fully charged, usually couple of minutes). Install/update this application with charger disconnected! Uninstall application with charger disconnected before upgrading Android system to new version (e.g. updating Android 2 to Android 4) License details at product homepage. IMPORTANT: Application will not work in case other applications interrupt with its function (Volume Locker, task killers, "profiles" applications, silent nights...) and those other apps will cause that volume is not restored and other system malfunctions. Either use Battery Charged Silencer or other app, but not simultaneously.
