TTR2 2.1.1 Tap Recognition Failure

After playing a good couple of games, rocketing me up the leaderboard, 'Get Smashed Gate Crash' comes on, which I rather like because I can 100%, however halfway through the song the game started randomly not responding to touches, loosing my streak and causing me to come 9th/30.

Also in 'Get Smashed Gate Crash' I find that it is also impossible to score points on all the shakes because the Phone recognises previous shakes as an early shake for the next arrow. Even when I shake it a really small amount and return to the central position asap I still find that the accelerometer must still be bouncing around or something because I can never score many points on that section and still keep the multiplier.

I also agree with the idea I read somewhere about having different levels of shake points like you do with normal taps. It's often online that when arrows appear that I move up/down depending on if I managed to get it in the microsecond time gap.

Also, I find that after a long session of tapping the battery in my iPhone is considerably drained and mid-song I get the 20% Battery left warning, this automatically pauses the game, however this still often looses me my streak. Is there any possible way of stopping this warning? I doubt it due to Apple restrictions but worth mentioning. (The recognition problem occurred when the iPhone was plugged in so I wouldn't suspect it's a power issue.)

Otherwise, awesome game, and just an Idea about preventing people hacking into the leaderboard and what have you, to prevent high scored over the maximum you could have the game store the time and length of each tap hold and shake and submit this instead or with the score. Then compare this with the 'notesheet' re-calculate the score on your server and use this. Although this may cause further lag issues it's just an idea.
