Hello there I have some tipps for you and some hidden options to show
1. to take a screen shot press and hold Power on/off and Volume down
2.the phone has tow shot down mods (normal shot down and Quick Boot shot down) press and hold power on/off and check it
by default the Quick Boot is on. (Quick Boot is just like Energy Save mode on windows) the good thing is that it makes the boot time shorter on Power up and Power down but you cant get into recovery so to Shut down the Phone completely uncheck the box and Power off
3. to get in Recovery mode after Full Shot Down Press and Hold down all three buttons together Power on/of & Volume up plus Volume Down
4. on home screen pull down the black bar from up down to get into notifications centre
Press the icon on up right corner to get into quick settings shortcuts mode
and from here you can go to Full settings menu by taping the up right corner settings icon or you can turn some options on and off (Wlan, Bluetooth, Data Connection and Auto Rotation) or go to the settings of the option by holding the icon down (when you hold the Wlan Down it will take you to Wlan Settings )
5. Battery & Storage
on Battery option you can turn on the Precentage indicator in the info bar beside the Battery icon, and get more info about your energy usage
Storage will let you get infos about your storage and select which memory is your default memory to install apps and save everything, the best thing is to use a Big & Quick micro sd as default storage so you can be able install more apps and big games
6.the Lenovo a369i has a very clever option to auto Power on & off called
you can adjust when the Phone power itself off nights and on at day to save energy automatic and if you where on call or you were using the phone a Notification will appear to inform you that the device will shot down in 10 seconds with cancel option. so you can set the device to turn itself off every Night at 00:00 and start on 5 minutes before your alarm every morning or only on some days.
7. Developer Option is a hidden option which can be activated from (about Phone) option
Tap on the build number many times till a counter show up which inform you how many times more you need to tap to get the option activated, after the activation this message will show up when you tapthe build number many times again
8.System updates is an option that will appear only when you update the device manually to the latest update
