Just Google SiS main page then find the warranty page.

Hi guys,

OK, I've read back the previous pages and it seems that there is some confusion regarding this button light problem thing.
I will try my best to explain the best that i can.
1. Json188. I sent to SIS in glenmarie. The HQ

2. Holyboy27. I got the phone on the 1st. I went to SIS on the 3rd to complain about the problem. They replace a new set for me immediately, but even that set was also the same. So, they told me that they dont have any stock so waited till yesterday to finally get it replaced. So that was actually the third IS. The second one they replaced.

3.Yehlai. I never said that all of batch 13 got this problem. All i said was that the staff told me that batch 13 was prone to this problem. Not all, ok..

4. ckming21. The video you posted highlighted about the light intensity of the buttons varies when viewed from different angles. This i can confirm is true. Believe me, i have had 3 IS in two weeks.

However not the same problem as i experienced. What my problem was that as you are looking at you phone , if you tilt it to any sides, you can clearly see the landscape button appearing. That mean the phone is still in portrait mode but you can see both the landscape & portrait button icons together.

I can confirm that this replacement one i got DOES NOT have the problem.
No matter which extreme angle i look at it the landscape button icon does not appear.

FYI.
1. This problem seem to happen only on the back & search button.
2. The 'light leakage'(posted by ckming21) is normal, but the double appearing icon is NOT
3. It seem the most visible when looking from extreme upright. That mean looking down at your phone buttons from top.

I think thats all. Hope i clarified some of your question about the buttons.

Cheers...

yah google SiS website and do product warranty registration

Same, i think server down, will try tomorrow. If not im going to call their customer service.

I went to the one in Glenmarie the HQ. Bring together the box cover and your receipt/invoice.

Remember to backup your phone though.

They will take the only the box & phone.
Box only the cover.The one with your IMEI & S/N printed on.
If they change a new one, they will also change the box, check the IMEI on the phone and on the box to make sure it matches.

How did u tell them ? they agree to change after view it or u keep on argue with them ?

I did say it was a "defect" right? Note the double apostrophe. When I got the phone I noticed this but didnt think it was a real defect since it was mentioned in some review I read.

Then a forumer said that SiS gave a replacement, which got me to say that this was not a manufacturing flaw but instead an isolated problem. For my case, I can still see it in dark conditions.
