Sony to fix Xperia Z Ultra, Z1, and Z1 C sound issues, Z2 Compact on the horizon?

Apparently, Sony's Android 4.4.2 KitKatupdate for its Xperia Z Ultra, Z1, and Z1 Compact smartphonescontained a malfunction which led to sound sometimes being directedto the phones' earpieces, instead of their internal speakers. The bugresulted in some users having their notifications, alarms, videos,and ringtones quietly blasting from their smartphones' earpieces.That must have been rather awkward.

Luckily, Sony will intervene with asoftware fix as early as next week. Here's the company's briefstatement:

Sony Mobile Communications wouldlike to provide an update in response to reports around abnormalaudio functionality and quality; that some users may be experiencingon their Xperia Z1, Xperia Z Ultra and Xperia Z1 Compact devicesafter upgrading to Android 4.4 KitKat. We have identified this issueon some units of these models, and measures have been taken toswiftly deliver a solution for our users. A fix for the issues willbe included in a new software release that will start rolling outfrom next week (w/c 7/04), with exact availability and timing varyingby operator and market.”

In other news, the unannounced XperiaZ2 Compact allegedly passed through the FCC under the moniker"Altair". The phone's model number is SO-04F, designatedfor the Japanese telecom NTT DoCoMo. It succeeds the Xperia Z1Compact's model number SO-03F, while the published schematic looksvery much like an expected successor to the Z1 Compact, similar frontcamera placement and all. In addition, Japanese parts sellerMoumantai has already listed a back cover replacement for the SonySO-04F that looks the part. Check it out in the gallery below.

All in all, that's fairly solid evidence that theXperia Z2 Compact is happening. Its ancestor, the Xperia Z2, was oneof the highlights at this year's MWC, sporting muscular hardware andpremium design. Sadly, an US carrier is yet to bring it to theStates.

Altair is a star. And Z2 was Sirius and Z2 Tablet was Castor. All of them are stars.

Also, 2012 phones were food. Pepper, tapioca, and coconut to name a few.

The Z2 hasn't even hit the stores yet, and Z2 Compact is in the pipeline already? The Z1S and Z1 Compact are relatively new to the market, too.

Sony tends to have a Japan-first mentality for its phones, indeed their best are kept for Japan (like the au-exclusive UL). Speaking of which if they had popped up the Z2C sooner I probably would've taken it over the XPERIA A (Z1C came a bit late too).

the problem was that z1 compact came too late. this means z1c has competition which is z2c itself. [i know there are some competition from sharp and other oems but there is no competition from top oems].

Well, if they differentiate the Z2 Compact a little... like making the screen 4.5", or focusing a bit more on speakers (dual)... it might have a different target altogether... Z1 C is still one of the smallest flagship on Android today... (from Top OEMs).. but a slightly bigger 4.5" screen Z2 Compact would fit users like me, that do not want a small screen with virtual buttons... Also the Z2 Compact will probably drop the ASF like the Z2 did... and that is actually a reason for me to get the Z1 Compact... I have experienced first hand so many drops that haven't end in cracked screen on my current Xperia that I ended up loving this misunderstood feature. What I am really worried about is the frame bending on all of those models... I though having a smaller device like the Z1 C instead of the big Z1 would help preventing the aluminum frame bending... but apparently it is not so.

Oh yeah give me Z2C. Z1C is great but screen isn't as good as competitors but if Z2's screen is as good as everybody claim, Z2C will rock.

This is what I love about sony giving customer PREMIUM PRODUCT in a fast pace world of technology . Sony doesn't care about how many they sold as long as they are the front runners in technology . Kudos sony for steady getting the top honcho of smart phones . Although I have my Z1c I'll just wait for Z3compact. I'm sure Z2compact is another beast phone.
