I've followed the feedback from ChuanHong on this thread, seems pretty positive all around. Maybe he can add more

All warranty claim now will be under Sony Malaysia. They are the one bringing Xperia to Malaysia since last year.

Initially they thought pull out from Asia region.. however, in the end they are launching the phone through sony store only.. no longer go though phone stall/shop.. that's what i knew..

Sony Xperia 1 that im having is basically 95% fine to me.. but there is some issues to me.

1. I having a memory card issue when launch camera app.. (once a while..).. assuming once a week.. However, relaunch the camera will fix it.. just not sure why.. im using SANDISK EXTREME PRO (the most expensive one..).. other than that, i think no issue like app crash..

2. Display mode: i chose Creator Mode.. but sometime it will change to standard mode (punchy colour), setting showing creator mode, but in fact display is showing standard mode colour.. you may differentiate between these 2 mode.. re-select creator mode will fix it.. however after May security updates and i didnt have this issue anymore.. Not sure whether sony fix it.. (this issue occur once a month/2 weeks)..

I did played PUBG, COD and GTA LCS (the most graphics intensive games that i have played in xperia 1).. so far so good.. no lag/throttle speed.. heat, from wearing casing + back screen protector, i cant feel it.. lets me try to play it without case tomorrow.. I did tried played PUBG and do screen record for half hour (1 match).. may refer video below. so far no issue.. hahaha..
haha thank you. i think i am the only one active user that holding xperia 1 in lowyat forum

The very first batch is Japan made. But subsequent will come from Thailand like the Xperia 1 case .These explained why someone got hardware problem but the rest don't.

Xperia1 not Xperia 1 ii

Made in Thailand got more issue, that why I have my Xperia1 ii made in Japan this time....

It is indicated on box that Japan made. You have to check with those importer or Shopee seller the country of origin.

i wondering i shoudl find way to import japan unit or not.

the only concern is their 5g n76 n77 n78, any pro here can answer if malaysia suport this length?

i am thinking to ask someone who will return to malaysia to help me get one, but problems is currently no one is returning to malaysia.

As long as it is 5G model, I am interesting. 8GB RAM is freaking ok, not needed 12GB and price increase later.

But from the spec seems not mentioned 5G. If final no 5G, then 1 am 100% not interesting and won't buy.

Oh I see, not huge differences then.

But if Sony Malaysia bring in none 5G model, I am 100% definitely won't buy it. No point getting no 5G phone now as it is basically similar price, no 5G phone is no future proof. The processor is 5G capable but if Sony blocked it, then it is not a wise move and will loose people interest on it.

Can be enabled manually, if not mistaken.

i guess it's hard to satisfy everyone. lol
