Your K5 play features a microSD memory card slot. If your personal computer has a slot for that type of card (Most laptop computers are so-equipped), you should be able to save music files
The K5 play is a smartphone. Most smart phones let you save any music file you could find online by touching and holding your finger on it, then selecting 'save.' Once the music file is added to your memory card, tap-and-hold it and select 'assign' from the contextual menu.
The Lenovo K5 play is an Android phone and there are plenty of free ringtone apps such as MP3 Cutter, Myxer and more.
The Lenovo K5 play is Bluetooth-enabled. Bluetooth is a wireless system which lets you connect your cell phone to other devices. If your computer is also Bluetooth-enabled, simply establish a connection between both devices and transfer your audio files from your computer to your Lenovo K5 play.
Since your K5 play is equipped with a sound recorder (also known as 'voice memo'), a very straightforward technique involves simply placing your phone by your computer's speakers, playing whatever song, music or sound you would like as a ringtone, and recording it -- you can even use your voice, your child's voice or even your cat's 'meow!' Record it with your phone and there you go! Unless that function was specifically blocked on the Lenovo K5 play, you should be able to navigate to the ringtones sub-menu and choose your new recording as a ringtone. Of course, the quality won't be ideal but, after all, it's free!
