Getting the most out of your i8910HD: Manufacturer Codes

with 14 comments

*#0228#

As I mentioned in my review of the Samsung i8910HD, there are several manufacturer codes that can be used to tweak performance of all sorts of different features. While the phone is very capable out of the box, it’s a real advantage to be able to access these hidden settings to tune your device exactly to your liking. In this brief, I’ll go some of the major tweaks, how to perform the tweaks yourself, and how to not damage your phone in the process.

This list is my compilation of information found on the Samsung i8910 Omnia forums and all credit goes to Briggs and the members. If you’d like to read about more device codes to experiment with,  please feel free to give them a visit and say thanks if you do.

Before you attempt any of the codes found in this guide, I want to warn that it is not clear what implications this may have on your warranty. While this guide is safe to make minor improvements to the i8910HD, I take no liability for any damage you do to your phone if you experiment outside the parameters of this guide, nor if your warranty becomes void from performing any of these changes. You are making alterations to your device at your own risk. It is also recommended you write down the previous values for any settings you change in the event you want to change them back to default.

N97 Tour: Day 12, the Presidents Walk/Ride and draw by number 2

leave a comment »

Yesterday was a day for Sports Tracker. Being the last day in Chicago, it was imperative to finish the last two challenges handed down from WOM World before we departed for New York.

The first of the challenges was to lead the group on a “Presidents Walk”, touring Chicago using only streets names after US presidents (excusing Lake Shore Dr). I spent a few hours planning the route on Friday but once we started it, we quickly realized that the “walk” would be much better suited if we had a faster form of transportation. We decided to rent bicycles from Navy Pier and it was definitely the right decision.

N97 Tour: Day 11, Chicago Mobile Camp

with one comment

Saturday was our third and final Mobile Camp at the Illinois Institute of Technology and it was a very mixed bag. The turnout was very low with only two attendees, which was the least of the three. Despite this setback, a lot more personal discussion came out of having such a small group and it allowed everyone to expresss their opinions without anything getting lost.

The most interesting discussion to me that came up at all of the Mobile Camps was why the US market is so different from the rest of the markets where Nokia’s devices are sold. In short, the US market saw the rise of desktops before smartphones, whereas the Asian market saw just the opposite, and Europe saw the rise of both at almost the same time. With that said, it’s no surprise that the iPhone has become so successful in a market that’s trying to get a desktop to fit in their pocket efficiently and with the immense amount of control the carriers have. It emphasizes yet again that Nokia needs to market themselves completely different in the US than they do in other countries and I think efforts like this tour are certainly a step in the right direction.

We also put together a video of Matthew demonstrating the video editing software built into the N95 from years ago that hasn’t been seen on more recent offerings. After seeing the demo and becoming much more focused on mobile blogging on this trip, I’d very much like to see this feature brought back on handsets in the future.

Big thanks to Jeremiah (Pseudofinn) and Craig (SockMonkey) for making it out to the Mobile Camp! It was great to meet you guys and share so many thoughts about the mobile industry.

I personally don’t have any images from the event, but here’s a picture of a movie poster mixup seen near one of the trains we took back to the hotel.

AT&T 3G and YOU!

with 7 comments

There seems to be a lot of confusion recently regarding a “NAM i8910” which includes the UMTS 850 and 1900 frequencies used by AT&T and the frequencies supported by the current i8910. Please read ahead and allow me to clear up this confusion.

1. There is no “NAM i8910” and there probably never will be.

The current Samsung i8910 supports quadband GSM (voice and EDGE data) and triband 900/1900/2100 UMTS (for 3G voice and HSDPA data). Samsung has not made any mention of plans to release a second i8910 with the 850 UMTS frequency for use on AT&T’s 3G network.

2. This may not matter, depending on where you are.

AT&T currently uses both UMTS 850 and 1900 frequencies to make up its 3G network in the US. Fortunately, the 1900 UMTS frequency is used primarily in their current infrastructure for most of their 3G coverage. That means depending on where you are, you may be able to access AT&T’s 3G network with only the UMTS 1900 frequency in the i8910 just as you would a phone that supports both frequencies. Aside from AT&T’s 3G data, the i8910 will work on ANY GSM network for voice and EDGE data due to the quadband GSM frequencies.

(Note: All further improvements to AT&T’s network is being done by adding UMTS 850 towers. If you don’t currently have 3G coverage in your area, and AT&T drops a notice on your door that they’re expanding their coverage, your brand new i8910 probably won’t be able to access the 3G data from the towers they just added.)

3. How do I find out what frequency is being used in my area?

Aside from the dozens of platforms and applications that can be used to find out which UMTS tower your phone is connected to, the easiest way is to give AT&T a call. If you can get connected to a technician who knows what he/she’s doing, they should be able to identify which frequency your phone is using in your area.

As a disclaimer, I do not take any responsibility if you buy an i8910 and it does not access AT&T’s 3G network, so please do not email me with complaints if this happens. The point to this post is that given the state of AT&T’s 3G network, there is a very good chance that the UMTS 1900 frequency will work just as well with the i8910 in its current state without a NAM version necessary. I can tell you from my own personal experience that both the Atlanta and Chicago metropolitan areas are heavily covered by UMTS 1900. Anywhere else will be up to you to find out.

Please drop a comment or an email if you have any further questions. Inspiration for the title of this post.
