Damri Apple, iOS7 is failed, I want my iPhone back to iOS6!

Question

iOS7 crashes my iPhone 4S frequently with no pattern. I can not use my phone normally, and missed several important calls.
Are there people bothered by similar problems?
Since Apple is not able to fix iOS7's failure at present, Apple should let users go back to the iOS6 if they want.
There is still a usable system in the world for my iPhone, iOS6.
Apple, let me UPgrade to iOS6! I just want my iPhone to be usable!

Other has beeen a problem for quite a while but I never had to resort to restoring the phone every two to three weeks. At this point "Other" is just the tip of the bug iceberg.
Music videos loaded on the iPhone would randomly show up with the iCloud icon indicating that they  were no longer on the phone even though they were. The cloud icon would appear next to many of the videos, and would randomly change to other videos upon closing and reopening the Videos app.
All the videos played fine in airplane mode so I know they were all actually on the phone and not streaming.
Opening the iPhone’s music library in iTunes would show many songs marked with a circle comprised of a dotted line to the left of the name indicating that (according to the Apple senior advisor I was speaking with at the time) the songs had not synced properly. Again, they played fine with Airplane mode enabled so the info was wrong.
Most recently, while I was keeping an eye on “Other”, I noticed I had 2.8 GB of “Other” in use and 6.5 GB free. I deleted an audio book and replaced it with another and did a Sync. Well, “Other” and “Books” (print, not audio, totaling about ~350 MB) vanished and I had over 19 GB free. As I hovered the pointer over “Audio”, “Video”, “Apps”, "Photos”, “Documents & Data” and “Free”, I added all the memory used per section and the total was about 67.5 GB. Pretty neat for a 64 GB phone. Needless to say I was very pleased to have been in a screen sharing session with Apple tech support when that happened.
I’ve also found one movie and three TV shows in the videos app that weren’t selected to sync to the phone. Incidentally, deleting them showed that they were stored in “Other”, not “Videos” at that time.
Then there’s random App crashes and the once or twice the phone restarted on its own. With Sync this iPhone over WiFi checked, it’s been a crapshoot if the iPhone would appear under Devices if the iPhone wasn’t connected by cable. Sometimes yes, sometimes no, no discernible pattern could be ascertained.
Naturally I tried *EVERY* troubleshooting step suggested by the Apple techs.
So I have very high hopes for iOS 7.1. I’ve been using iOS since the original version and iOS 7 is the buggiest version and the first version that required a full restore every two to three weeks as part of regular maintenance. It’s gotten on my nerves and I hope that at least some of the problems have been addressed.
