The home screen reloads happens with Touchwiz. Its kind of a serious bug on what is suppose to be Samsungs flagship phone. You would never see something like this on iOS or WP8. Not even stock Android of the Nexus.
Im not criticizing Android here. Im criticizing Samsung. Android is awesome.
Anyway, I already rooted and have found several solutions: a ROM like Omega, CM9 or 10 or use Titanium Backup to freeze Touchwiz and use Nova or Apex.
Theres no perfect phone. HOX has wifi problems, Nexus bad battery life, SGS3 the home screen reloads and bad wifi for me (it disconnects on its own and then connects again several times a day), etc. These are not hardware problems, but rather software problems, due to Samsung ********* pure android.
Maybe some people havent noticed this, but on touchwiz theres not even a spell checker! I installed CM9 and 10 and on stock android there is. Im talking about the red line that appears under a mispelled word, just like on iOS.
Can someone please tell me why Samsung would do this?? I need a spell checker for emails, notes, etc. Its so stupid from Samsung to do this that just proves my hate for them.
Thats why my next phone will probably be a Nexus.
The reloads happen specially if you have many widgets. The Samsung Weather widget is the one that makes the redraws happen more often. But whats the point of having widgets if you cant have more than 4 or 5 to avoid many screen reloads?
Also let me say stock android keyboard is awesome. Much better than stock iOS. After trying it on CM10 you can see how BAD samsungs keyboard is.
Android has many benefits, but also some drawbacks. Widgets eat battery faster, but also many background processes. I hated iOS multitasking before, but now I really think is the best way to go. If you install many apps on android there can be so many background processes eating battery life without you knowing it.
I also miss the lockscreen iOS notifications, and how they show more información than on Android. Still, iOS is really lacking. It would be awesome if Apple included a swype-like feature on iOS 6.1 or 7.
Android is better than iOS, but iOS wins in some basic stuff: battery, multitasking, notifications, etc.
Android wins in keyboards, customization, the AWESOME back button, widgets, ability to jailbreak (root) easily always (and not waiting months for a jailbreak only to be pointless after the next Apple update. I hated that cat and mouse game), file browser, etc.
Well maybe not but you dont have to use TW either and imo, its not as good as Apex or Nova. But to counter, Samsung would probably not release a phone with a really horrible Maps or bluetooth that dont steam your music without hiccups. iOS 6 has its issues this time around so you cant say you would never see something like that on iOS anymore.
At least you have a quick and easy fix for your problem that doesnt require anything but a App download instead of installing a whole new ROM but for some reason you choose not to use it. There are also other keyboards you can use. I dont know why you arent taking advantage of these things.
I dont have issues with my Wi-Fi either. Stays on till i turn it off manually or by using my NFC tag.
