Like an idiot, I updated my phone today when prompted. Nothing is working correctly. I cannot text by swipe (when I tap on the blinking cursor in the text box, nothing happens.) I get the message "Swype - Open of EnglishUS failed! What does that mean? I have had to charge the battery twice today, my e-mail is completely reformatted, a voice tells me who is calling everytime my phone rings......HELP!!! Can I uninstall this update? Can anyone help me???
First of all, welcome marnie17!Like an idiot, I updated my phone today when prompted. Nothing is working correctly. I cannot text by swipe (when I tap on the blinking cursor in the text box, nothing happens.) I get the message "Swype - Open of EnglishUS failed! What does that mean?

Actually it has nothing to do with size. It's the impedance that increases current draw. You can get the exact same size 'phones from a certain manufacturer in different impedances. Ohm's law says that lower impedance makes more power (provided the amplifier is capable) and thus more volume. The problem is that the sound pressure level dissipates exponentially with distance. What that means is that earbuds that put the sound millimeters from your eardrums are WAY more efficient than full-sized headphones that have the drivers an inch or two away.Also worth mentioning is that using "good" headphones with 40mm or 50mm drivers will also deplete a battery pretty quickly.

At the high end, Etymotic makes some really high-end (meaning costly) earbuds. At the low end, my $15 and available almost everywhere Koss earbuds are hard to beat. Since the SII lacks the hi-fi audio that the first S and SIII have, you might as well save your money. FYI Koss also makes more refined earbuds, but you'll have to look for them. I found mine at Full Compass right down the street from me, and a major mail order pro A/V retailer for non-Madisonians.
It should go without saying to practice moderation when using the volume control. Your hearing can be damaged easily, and what you lose will never come back. If you love music, love your ears too, so you can enjoy listening to music for the rest of your life.
I did a hard reset before the ICS install myself, and noticed that after the reset that I suddenly had software updates that didn't show up a minute before.After reading way too much on this topic all over the nets, I finally did a hard reset on my 2 month old SII...
...I didn't see this after I received OTA 4.0.4 and restarted, so I'm thinking that might have been an issue.
the ICS update had prompt my phone to download, but the download failed, when I tapped the ( retry download ) button it will not let me, I tried rebooting the phone, and still get the same message - failed download and will not let me re download when I tap the re download button, any suggestions please?
I want to know if there is anything I can try to have my phone let me try to download the update again?
Just install it manually, look for the video on youtube. Took me 5 minutes and worked like a charm.
its working now thanksJust install it manually, look for the video on youtube. Took me 5 minutes and worked like a charm.

It looks to me like the practice "reboot like people vote in Chicago: early and often" is sound. Especially when making a major OS change.
A factory data reset (aka hard reset) will clear out two things in addition to user data and your installed apps - the operating system cache and the Dalvik cache.
We typically recommend doing it on major OTA updates (or whenever your phone gets squirrelly for no apparent reason) because just like when your browser gets all wonky, clearing cache cures many ills. Caches are great, they help keep things running faster and smoother, but once they get tangled, all heck breaks loose. (I once cured my voice search launching my keyboard in Spanish just with a factory data reset - when I say squirrelly, I really mean it. )
And for whatever reason, the carriers/makers don't include the cache-clearing commands on their OTAs, something that many of us have complained about for several years here. Experienced rooters know to clear those caches as a matter of course when installing rom changes, but it's a open secret kept from the non-root community. It's also the first thing that Sprint will do when you take a phone in with bug complaints - and now you know why.
Best practices -
Begin by ensuring that your contacts and calendar events are sync'd on the Google web so you don't lose anything. You can make just a user-installed-app backup with EStrongs File Explorer, but if you don't mind spending a few bucks and saving a lot of time and grief, use MyBackup Pro to save your apps and most of your data. I would especially recommend MyBackup Pro in the event that you've moved apps to your sd card. Try SMS Backup + or similar to save SMS messages you care about.
Once ready, do the reset and if this version of your firmward has a place there to also erase or format your sd card, skip that - there's nothing on your sd card needing erasing. If in doubt about this whole process, go ahead and back up your sd card to your PC - that never hurts, always a good idea, those things don't last forever either.
You will have to set up your home screens and accounts/passwords when you're done, so there is a minor nuisance there.
Hope this makes sense and helps!
PS - a big set of SMS messages can certainly lag your phone, so think twice before restoring year-old messages you don't care about there.
Early,
Short of doing a full-frontal-assault hard reset, what are the best practices for clearing as many cache repositories as possible? Is there a simple way to clear all caches in just a few taps?
Don't be put off by the "hard reset" nomenclature. All it means is that you're rebooting. No settings will be lost. MOF a good reboot is often useful for unsticking things and restarting stuff that wasn't working.Do you think if I follow suit and reset my phone now will help with my issues? (even not having done it prior to update?
If you don't feel comfortable doing it, then don't. It's still your phone and your life. Remember that advice is something that you control. Don't feel obliged to take any advice.(I noticed there are lots of files and residues left in my phone that I am afraid to delete for not knowing where they belong to or if they are useful at all...)
IME sluggishness is more often a sign of something dominating CPU usage. On computers, things can use up all of the system RAM, which slows things down. Casual users often confuse the system RAM with the system storage (where the files live) and think that reducing the number of files in storage (the hard drive) will speed things up. This is almost never true.Also my scrolling for contacts or anything is kind of sluggish lately.. probably called by excessive number of junk files left behind...
No, the "hard reset" will not do that. The FACTORY reset is the one that wipes out all of your personal data and programs. IMHO this should be used only as a last resort.I think I will reset to factory specs anyway as well, so.. thanks all for a great informative thread...
Early, I found that AirDroid has an "App info" page in the Tasks applet that comes up when you select a running process and select "Force stop". There are "Clear data" and "Clear cache" buttons. Sometimes one or the other or both buttons are enabled, or not depending on the process. I'm guessing that their availability is related to the level of privilege that they run at. Is this a possible (albeit limited) way to clear some of that protected cache?Boy that would be nice - but without root privileges...
A lot of the stuff you want to clear is on a memory partition that only the system and privileged apps can write to - and the makers and carriers decide what privileged apps are, you can't just have one easily to go into those areas (again, sorry for the broken record - unless rooted - because being rooted is the same exact thing as getting Admin access on your PC).
