I am indeed surprised that you are now using a S4 despite your unhappiness over it, which you had clearly expressed at : https://forum.lowyat.net/topic/2793148
You didn't do any research before buying it ??  Based on all your comments you appear knowledgeable-lah !! Than why buy it ? To convince yourself is a lousy phone ?

I quote some of your comments :

Firstly, S4 doesn't have LTE. Ppl who tell u that it doesn't matter bcos u might not be always in LTE areas are just plain idiots.
Rmbr, u r paying over 2k plus and SAMSENG doesn't give u latest tech. Fact is, they are just greedy and love to milk fanboys tits dry.

Secondly, s4 is all plastic crap. They used the fugly design over and over in budget and mid range models. WTF!!!
Imagine if u pay over 180k for Honda accord. But the same body with only difference wt Honda city is just the size, engine, more cabin lights, etc.

Thirdly, s4 has nothing new to offer compare to s3. With nobody to copy, SAMSENG struggles to capture the imagination. Foolish gimmicks like air view, smart stay only impress stupids.

HTC on the other hand, uses premium materials, real innovation with sense technology.

What is the point of having powerful processor if the software is still crap? Many ppl has complained that the gallery is lagging even though with octa core and 2 gig RAM!!!!
Even iPhone 2G never lags even a heartbeat when viewing photos.
SAMSENG engineers are only concern on making the best software for the next model e.g. Note 3, s5/6/7

If you recall, someone had the avatar of a hulk with a 2 colored face. Maybe a severe case of schizophrenia (there was a term another forumer used earlier which I can't recall) manifesting itself here.

Now I recall - Dissociative identity disorder
