iOS 5 Compatibility Report (huge, tons of tested titles!)
(Posting here as the official Apple forums are down so I can't share my thoughts, warnings etc. with anyone there.)
First and foremost, the current iOS5 beta1 on the iPad2 is far-far mor reliable than 4.2 beta1 was on the iPad1 back in September, 2010. That is, if you are afraid of installing it because of your bad experience with (early) 4.2 beta builds, just go on and install.
HOWEVER! This only applies to the Wi-Fi iPad2 (it's the only iOS device I've installed iOS5 on). I can't speak for the iPhone / iPod Touches / 3G iPad2 models / iPad1 at all.
Also, make sure you thoroughly read my report.
While compatibility with existing titles seems to be 99%, if you play iPhone game titles, the lack of antialisation will COMPLETELY ruin your experience. (Yes, I know what I speak about and yes, this build of iOS5 does lack antialiasing – don't tell me my eyes are bad.)
So far, I like the most:
- the iBooks dictionary is accessible anywhere where the standard copy/paste control is accessible. (Also works with the officially available iBooks.) Then, just tap the new menu item „Define” to look up the word. It's, apart from not having the spoken version of the word (it does have the standard English spelling and pronunciation help, though), vastly superior to the scriptlet-based, commercial solution (
Tap-Dictionary;
http://itunes.apple.com/app/tap-dictionary/id420174330?mt=8 ) so far available for any UIWebView-based, scriptlet-capable apps (Web browsers, mainly). The only downside is that it can only search for English language words, while the service can look up in any language.
- iTunes syncing in the background, while you can go on doing your work in the foreground, with almost no speed impact. (At least on the quick iPad2) This is a KILLER feature and ALONE makes it worth upgrading to iOS5!
- in MP4 files, embedded subtitles are rendered with bigger chars (no need to use third party movie players any more)
Third party app / game compatibility report
I've tested it with almost all video players (DOTORI PLAYER By JUNG DISK 1.3.4; BUZZ Player HD by BUGUN Software 1.8; Movie Player – Plays any Video! By Dominic Rodemer; ATK Player By Khoa Tran Anh 2.0; Azul Media Player - Video player for your iPad By Gplex 2.0; AVPlayerHD By EPLAYWORKS.Co.Ltd 1.422; eXPlayer HD By Zhigang Chen 1.3; GoodPlayer By Hustmobile 2.1; Sub Video Player for iPad By Noteloop 1.0 (=Remux MKV Player); OPlayer HD By olimsoft 1.0.16; VLC (AppStore); yxplayer By mobilesoft.kr 1.2.5; CineXPlayer – The best way to enjoy your Xvid movies By NXP Software B.V. 1.6.1), Operation Wow HD, Orions2 (games), Sygic Aura / iGo Primo / Navigon Navigator (nav apps; tested with European maps), GoodReader (the best e-book / PDF reader / annotator), and 360 Browser / Atomic Web / Opera Mini / iCab Mobile (Web browsers). Of them, it was only with iCab Mobile that it immediately crashed upon trying to load any Web page (including the default iCab homepage); no problems encountered with the other browsers so far.
Speaking of video players, hardware MP4 decoding doesn't work in one (excellent) third party video player app (
AVPlayerHD By EPLAYWORKS.Co.Ltd 1.422); with it, you need to switch to software decoding. The other video player apps are not affected and I haven't noticed any video playback speed degradation with any of them, compared to 4.3.3 on the same iPad2 (I've tested with tons of video formats - just working on a major roundup of video players -, about half of them high-res).
Problems
Brightness
While Apple state it'll be easier to decrease the brightness level in third party apps (just like in iBooks), this should be made system-wide. While my iOS5 iPad2 is a tad darker (when the brightness knob is completely on the left) than my iOS 4.3.3 iPad1, sometimes even darker rendition would be preferable.
Still glitchy scrolling in UIWebView-based apps
The same ugly stuttering while scrolling as before – nothing seem to be changed. This almost completely ruins the experience of any third-party Web browser (except for Opera Mini, which isn't UIWebView-based).
No anti-aliasing in 2x iPhone emulation mode! (Gamers attention!)
This is a MAJOR problem and makes iPhone titles pretty much useless; with games, unplayable. Tested with Orions2, Tiny Wings, Angry Birds, Real Soccer 2011 (some of them having Retina support, some others don't) – all pixelizated. Speaking of Retina, Apple still doesn't seem to want to support Retina screen emulation. It's probably the only reason I'm still jailbreaking my iPad 1...
No audio resume
If you sync in the background while the active app plays music, playback may not resume (e.g., Orions 2). This isn't a problem of OS5, though, and will surely be addressed by game devs.
Crashes resulting from memory shortage
While I certainly welcome the new memory / reference handling / counting model (pretty much the same as automatic garbage collection on OS X), the BIGGEST problem with iOS, that is, the immediate app crash upon running out of memory, hasn't been addressed. This should be the FIRST thing Apple takes a look at!
Needless to say, UIWebView still seems to use a LOT of memory – no changes there either, unfortunately.
