theoretically death grip for Digi user will be more obvious wan for sure!

When your signal is on GSM 900 (Maxis) u wont have death grip issue.....

When your signal is on GSM 1800 (Digi) or 3G network which MY is using UMTS 2100 (Maxis & Digi), you will have death grip issue!

GSM 900 is the normal GSM/GPRS/EDGE speed (when u see 'O' or 'E' or nothing after your MY MAXIS wording)

UMTS is when you see '3G' next to MY MAXIS.

I am just stating a theoretical fact only, death grip also depends on several other factors, like indoor or outdoor, on ground level or elevated, how strong a reception at your area, etc.

Basically, the higher the frequency the phone is working in (1800 - 2100Mhz) the more susceptible it is to so called death grip.....just go get a case / bumper for your phone and you should not encounter it nemore.

I don't think there's anyway for Apple to address this issue properly since its a design flaw unless they change the entire design / outlook of the phone.

The most probable way to address this issue is to bump up the transmission power but this is not healthy and may not pass the authorities as it will increase the SAR (specific absorption rate) rating, not to mention this solution only solve half of the problem...the receiving part is still the same (signal may still drop). Hope Apple is not going this way.

So all in all, yea, there's no solution to it.

Its a technical standpoint la...but yes, I do personally experience these as well on my friend's SG iPhone 4 on both Maxis n Digi.

Lets say originally you have 5 bars....death grip u may reduce to maybe 1 or 2 bars.......but when u originally have 2 or 3 bars...death grip may let u drop to zero bar. It depends on situations.

And you're rite, SG, Maxis, Digi and whatever country / telco iPhone 4 = Death Grip issue.

In certain situations where signal is already not at its best, death grip WILL cause it to drop calls. I've tested both Maxis n Digi......drop calls on digi is more likely compaed to maxis

SGP steinheil anti-fingerprint SP does not confuse the prox sensor.

those are spots or lines....if whole screen yellowish is different story me guess.

Thats good news! Lucky u..at least now we know they have some buffer stock for warranty replacements.

bro, do tell more, where u get, what time u get n all....so that its helpful for other members here whos still looking for one.

I find it does have issue, at least to my iP4....did not drop calls so far...but signal does drop from 5 bars down to 1 (in 3G)

I've already upgraded all the way to IOS 4.1......i see the bars pretty much the same behaviour la.

But so far IOS4.1 no probs at all!! Safe to upgrade!
