Phone clock will reset when battery took out for long time (I not sure how long, maybe 5-15 minutes??). Same thing happen to battery drained until 0% and not immediate charge it. This is normal phenomenon.

How old your battery now? Almost 1 year? Charge and discharge process will deteriorate your battery performance from time to time. If your battery still new, there are many factors can cause battery drain fast depends on your usage, apps install and many more. Try study your battery usage first, look which process drain your battery more.

What's your firmware version? 2.3.3 or 2.3.4? Sweep panorama is new feature for firmware ver. 2.3.4.

Currently, "power save mode" still exclusive for Xperia Ray only.

Not sure Arc/Arc S can get this cool feature in future firmware update??

I don't have iPhone, don't know how convenient to switch between different languages.

For Arc, switching languages not too bad. First, type SMS in english, then want to type chinese text, just touch and hold for 2 sec at SMS typing space. It will pop up a window to select "input method", if select "chinese keyboard", then can type in chinese. If want change other languages, use same procedures to change "input method".

No problem for me to change languages during typing SMS.

So far so good, no battery drain issue.

Xperia Arc has same panorama features as Xperia Arc S.

Ori set come with 1 year warranty from authorized distributor, able to claim the warranty at any Sony Ericsson authorized service centers around Malaysia.

AP set depend on AP companies, some give 1 year, some give 2 years. Warranty claim only at AP companies or shop which bought the phone.

Accessories might be different between ori set and AP set.

Of course, more warranty year more better, but depend on warranty coverage (accessories, LCD or battery) from AP companies. So, better ask AP companies staff what kind of warranty coverage included before purchase the phone.

I think design flaw rather than plastic quality. Most of us cracked at bottom of proximity sensor. If they can adjust the proximity sensor location higher a bit, so more material will allocate at this tiny area. This should be reduced the crack issue a lot.

According Sony Xperia Product Blog, Arc s will get ICS on end March/early April 2012, while Arc on end April/early May 2012.

I already used this phone almost 6 month. There is a tiny crack under proximity sensor. But very very hard to notice unless put under very bright light, then can see a tiny line. I think very hard to prevent it from crack no matter how careful you handle it. I used melkco leather case (hard cover type) to protect the phone, somehow it cracked too.

Anyway, still no regretted bought this phone, it can meet my need.

ICS upgrade push to mid-April for Xperia arc S, while for Xperia arc only can upgrade from the end of May/early June.

Normally, Malaysia update a bit late compared to other countries, so be patient. If you can't wait, can flash with Official Sony ICS Rom.

Normal Arc will get ICS upgrade starting from the end of May/early June.

Go to Settings->Applications->Manage Applications->Google Play Store->Clear Cache.

Transfer all apps back to phone memory (temporary only). Then copy/move all files from 32GB memory card to 8GB memory card. Put in 8GB memory card to arc. Transfer apps to memory card again.

Maybe telco service down or SIM card problem. Do you test with other SIM card?

Normally, seller say charge 8 hours. But, I think no need because when it reach 100%, it stop charging. Why waste power?

No.

Press "Power button + volume down button" at same time.
