I should have known better than to accept such an update. I should have kept telling it to go away and waited. From what I can see of this update it sucks horribly and from what everyone here and when I Google it are saying. It's terrible. It sucks. I honestly wish I could go back, but guess what? A so called factory reset doesn't reset to factory defaults. The phone will retain all updates to its core. Factory resets only erase all of your personal data. (Shouldn't be called a factory reset if it isn't going to reset the device to factory settings as a whole.)
I can barely text anymore. The fat space for my contacts info stays in Landscape view. They expect me to read what I am trying to reply to in a just a few centimeters of space. I took a screen shot for reference, though I am sure most of you reading this will know what I am referring to.

So the big blue bar is the "Contact bar' then "It does" is what my friend sent me in a text. That just isn't enough space to read anything, what the heck where they thinking when they released this update? My text was in reference to the fact that I was unable to see what I was typing bellow the word prediction box. Then it decided to bump down a bit and actually let me see, the way it's supposed to work. But it didn't even go down far enough. This is by far the most aggravating thing in this update. Why did I trust any update at all? Well HTC has been great so far and never had a bad update for me before. Just the worst. I've since removed the text all together. I still have auto-correct but that only does so much if I attempt to write a word I rarely use and for some reason have trouble spelling. Then I have to google it to make sure its right. (The word predictor doesn't always do it right and I have written at least ten real words you can find in the dictionary that I had to add to my personal dictionary in the phone previously. It's probably more than that.)
The drop down menu for notifications sucks. Who the heck thinks that this is a good function and that it would be intuitive to use? I have to swipe down for updates, swipe down again for my not so quick settings thing. Then there is the search through all this weird boxes in a scrolling fashion to find the stuff you want. Seriously wtf? I want my simple easy to see and switch between boxes, thank you very much. I don't see why Android OS has to change this much every single time. At least let us revert back if we don't like it, or change the visual look/operation back to the previous set. Phones are smart, they should be capable of this.
Suppose I have been fortunate not to have any real errors yet besides one. I somehow broke it and it error-ed out of my messaging application because I attempted to send a photo and it lagged and broke. Not like I did anything out of the normal. Also thinking that lock screen notifications was being "Added" according to the information for this update was just stupid. This phone already had that functionality and I had already turned it off. The update actually turned it on and also renamed the setting to something absolutely ridiculous that took me forever to find, it took me a minute to even locate it again just for this. Which sounds really dumb, I know, don't give me grief about it. I have no control over what notifications get blocked now, just all of them or all of them... I can still easily bypass the lock screen by swiping my quick settings down and hitting the settings button at the top. I can then hit the home button, or the two box button and go where ever I feel like just as before. Though setting a PIN lock does prevent this bypass (as does any other real security measure.) It still seems ridiculous that the supposed lock screen doesn't actually stay locked.
I realize this post is a bit long. Having glanced through here most people just write a little tid bit about a specific issue or are really vague about the entire thing. I feel your pain, I hope you understand mine. If I get anything out of this post (and I hope I do) it's that the landscape texting will get fixed. Please, please for the love of all things... Fix this! I can barely text with it so broken!
