As a developer I can say I've had fewer issues with this beta than ios 7 but everyone's experience is different. I don't have issues sending texts either however I have encountered a few different bugs but they were small and bug reports have been made.
iOS 7 was similar early on as well but I don't recall as many bugs making the phone and anything else nearly unusable and undoable as this go around. With any luck there will be big strides made with this next update as there was from 2-3 or 3-4 last year, can't remember but one update was a quantum leap, and the ship will be righted. Until then my experience using iOS 8 on a personal and professional level can best be described as poor. The irony is I think it actually got worse from Beta 1 to Beta 2.
Hate to sound generic but have you tried a fresh install straight to beta 2?
I typically consider such advice to be unnecessary however I had some issues with ios7 beta that carried over to GM. Just assumed it was bugs they hadn't fixed but when 7.1 came out and issues persisted I did a fresh install and all issues went away.
I'll also add bugs I've experienced on my iPad air currently on ios 8 beta 2 is being unable to use the app switcher to change apps. They always crash. I have to go to home screen then either use multitasking or go to the app to launch without a crash. This isn't present on my iPhone 5S.
Just some of my personal experiences and I only suggest a refresh because I'm not seeing the issues you have so maybe a fresh install may fix it?
Regardless as you can see I've had odd issues previously as well and I typically have 40-50gigs used so a fresh install takes hours..
Like you waiting for beta 3.
Most beta 2' last 15-20 days so hoping for a surprise this week but realize it may be next week. I personally think when they hit their predetermined milestone it'll ship which could even mean a weekend release, has happened before but IDK about a holiday weekend release.
People keep saying next Tuesday but surely it would be fair to suggest it could still be anytime this week as Apple don't exactly have a track record of uniformly releasing new betas every 2 weeks.
[MOD NOTE]
Stay on topic, and enough with the arguing and bickering.
They have almost always done it at 2 week intervals followed by 3 week intervals later in the process.
I was really hoping b3 would come out yesterday. Having significant freezes and issues requiring hardboots, or I'd be typing and it would lock up and respring, some really crazy stuff.
Dont fret. The longer its in development the better it will be.
Not fretting, just hoping. Plus I think the delay may be the July 4th short week.
Apple tries to release a new beta a month before the expiration of the current beta if they can.
iOS 7 beta 1 had an expiration date of July 24, and beta 2 came out on June 24.
Then iOS 7 beta 2 expired on August 8, with Beta 3 coming out July 8.
And then Beta 3 expired August 29 with Beta 4 coming out July 29.
The pattern stopped after Beta 4.
So iOS 8 beta 1 expires July 16, and Beta 2 came out June 16.
iOS 8 beta 2 expires August 7.
My prediction is Monday, July 7.
July 7th Yosemite DP update 2.
July 15th IOS8 Beta 3.
