Recording issues solutions- may work for some people
If Your recording is slow, weird, voice crack ,, distorted , not connecting headset mic properly.  ???
Ok 
This may work only if your phone plays old  recordings and others Collab is playing fine?
Then do this
First try recording without headset , now check that your recording playing fine.
If it's fine now connect the headset which comes without mic. Don't use inbuilt mic headset. Bluetooth headset set may work , but may delay or slow  or stop sometimes while recording. Better use  headset which comes without mic. Now ur voice will be received by phone mic. 
Volume level should be below 50 %.
Now Your voice will work almost good.
Your phone mic may not receive your voice properly while singing, till software update from ur phone  or karaoke software update. 
so your mouth should be little bit close to your phone mic. Sing a bit louder.
 All the best

 friends
Thanks
