Nothing has been resolved with iOS 9. With the update .01 nothing has been resolved.
The only help we can be is to enjoy what works. This will be the most buggy edition of apple history.
So, grin. Have the best time with your purchase you can. To write about problems will not fix anything. We all are aware that if one thing is fixed, it will affect all systemwide. This is good. It is the best fail safe we have. The software will always be flawed and will drive the writer's insane.
As for myself, I am getting close to the point of where I was with the last system I used for 15 years. Why?
I was able to somehow avert all the problems associated with all up dates until 8. The fixes started multiplying problems to the point of I found I was no longer interested in learning tech. My desire was gone. Instead of making my life simpler, this was making my life hard.
I feel I am not able to release facts of a convesation with a girl who saw my inablility to cope with the ever increasing problems and the redundancy associated with having to go to three obscure places to do one simple task while it could all be on one page. My problem was not unique. That's as far as I feel I can go on that topic.
Fortunately, this year there was nothing that interested me except for Apple TV. I was granted a year pass from upgrading devices each year since iPad 2.
The last straw, so to speak, was after downloading the 8 series, I had gotten use to the instant on. Why I let the issue go? I realized apple would not cut their head off to spite customers. It had to be a hack where the instant on was causing problems security wise.
With 9.0 and housekeeping 9.01 with many others slated in quick succession I look at it as consumer protection. After getting along with 5 gig of free memory since I began, iOS 9 by default turned all settings to on in the 'cloud' to save to my portion of a hard drive somewhere, everything. As a result, all pictures taken for years and years with HDR, Do Not Save Originals, suddenly were there, saved on the storage hard drive.
I found that I had to pay .99$ to correct a mistake I was not informed of. No problem. However, the saves were cumulative and out of five free gig for two devices with 1.3 gig left, I was now at 26.3, then 49.5. The easy downgrade required a call to support, it was not as simple as flipping back to normal. So, for the first time, I have no backup, even though the service was cancelled and reset, some state laws require refunds be given to comply with law.
This was silly for .99$ but it was the only way to get my free 5 gig back. An ensuing email told me my backup of pictures would be erased .... in 30 days. Great, that was something I had already taken care of long ago, now, thirty days with no backup.
All this to say, get use to problems or don't buy the product. I'm sure I'm not the only one who noticed the creepiness of the last release show. Something wasn't right, Most of the people there looked scared, at the very least, extremely uncomfortable. the point had finally come, one size does not fit all.
I am forced to now think of all the problems as a good thing. The software will never accomplish what it is suppose to. Each additional improvement with come with it's own distinct set of other fixes. It is the failsafe, the hole where those with skills can penetrate and stop devious behavior. If this wasn't possible, we would be cooked !
