By convention, Nokia N-Series products will have their model number prominently marked on the fuselage, and N91 is no exception. Like the N70, the identity of the phone is also stamped on the upper left corner of the front. Further down is the N91 equipped with a TFT screen with a viewing area of ??2.1 inches and a standard material of 260,000 colors and 176×208 resolution. However, the display effect of N91 is average and does not bring us more surprises like N70 and 3250.
At the bottom of the screen are the ribbon buttons of the Nokia N91. If you look at this part alone, you might not think it is an S60 platform smartphone, because it only contains left and right function keys, answer/end keys and a five-dimensional joystick. Compared with the direction control units of the 3230 and 3250, the joystick of the N91 has not improved much in terms of ease of use. Although the positioning is accurate, the feedback force is slightly poor. It is still worth learning from the predecessor 6600.
Down the ribbon is the music playback button of Nokia N91. Unlike the 3250, which has to be turned around, we can find and use them on the front of the fuselage anytime, anywhere. The four directions up, down, left and right are used to control play/pause, stop, rewind and forward functions respectively, while the one in the center is just for decoration and has no practical significance. The individually designed button in the upper right corner is the player's shortcut key.
Sliding cover/number keys/right side of the fuselage
N91 is the first product in the Nokia N-Series series of mobile phones to adopt a sliding cover shape. But it is different from the upper and lower layers of 6270 and 6268, and it is also different from the "golden cicada escapes" of 8800 and 8910i. The "sliding" of this machine is limited to the module where the music playback key is located. This design is consistent with the 8850 and 8855 of that year. of. The slide-open part of the Nokia N91 is only about 2.8 centimeters, so the N91 has designed the ABC pen keys and C delete key arranged on the left and right sides to be vertically elongated at the expense of the size of the numeric keys. In addition, the menu of Nokia N91 is on the right side of the fuselage. In this direction, the only silver-white button is particularly eye-catching. On the other side of the fuselage, there are many "firsts". Here are the volume control keys used for the first time in Nokia Series 60 smartphones; and the first miniUSB interface in N series products. The Nokia N91's 64-chord speaker hole is designed below the volume control keys. Although this is the only part of the entire fuselage that can produce sound, the volume is very loud. The vibration combined with the transparent ringtone ensures that users will not miss an incoming call to the greatest extent.
The top of the N91 fuselage is designed with a HOLD lock switch and a standard 3.5 mm headphone jack. Next to it, there is a gold finger slot for wire control. Of course, the N-note switch key will not miss this part. There are relatively few elements at the bottom, with only one charging port. Since the N91 comes standard with an AC-4 charger, this jack is slimmer than previous products. The birth of a batch of N-Series series mobile phones has marked the entry of Nokia's mobile phones into the 2-megapixel era. Although the N91 has not obtained the "Carl Zeiss" optical certification like the N90, nor can it support 3x optical zoom like the just-released N93, but as a mobile phone that pays more attention to music functions, the N91 is equipped with a 2 million The pixels are 4.8mm and the 1:3.2 camera is enough.
Although Nokia N91 is not equipped with a large-capacity BP-6M battery like the 3250, the BL-5C lithium battery is still basically used for talking for about 10 minutes a day, sending and receiving more than 20 text messages, and taking 15 photos. It can be used for 3 days and 2 nights. And if you play music continuously, it can also support more than 8.5 hours.
Let me introduce to you the standard configuration of Nokia N91.
In addition to the host, there should also be wire-controlled stereo headphones HS-28, lithium battery BL-5C, travel charger AC-4, USB data cable DKE-2, charging adapter CA-44, desktop charger DT-10, and CD-ROM CD and "User Manual", "Quick Start", "Additional Application Guide", "Music Synchronization User Guide", etc. If the user purchases the large-package "Sennheiser Music Special Edition", there will also be a PX200 over-the-ear stereo headset inside. 1 is the first smartphone released by Nokia to use the latest version of Symbian OS v9.1 operating system and based on the Series60 3rd Edition platform. However, it is the same problem as the 3250 that was first launched on the market. Since the new S60 III platform has made changes in the compiler, system security model and core, the previous sis files must be compiled with the new compiler. Recognized and installed by the phone. When I logged into the official Nokia European website and tried to install the two games Punkwigs and Snakes, a Tunes Studio program and seven themes including blaster, Disc, Diversion, Hiphop, Rock, Techno and Turntable provided there for the 3250 to the N91, Only Snakes, Hiphop, Rock and Techno are compatible.
These compatibility restrictions are limited to third-party sis programs for the Symbian operating system. The JAVA extension is based on the MIDP 2.0 environment and can also support Mobile 3D Graphics API (JSR 184) and Mobile Media API (JSR 135). For the Nokia N91, you can still use it to install and run the three versions of JBenchMark I, 3D, and HD, as well as the newly launched and more demanding SPMarkJAVA 06 to judge its quality. (JBenchMark I is not compatible) JBenchMark Ⅱ/3D/HD and SPMarkJAVA 06 scores
JAVA software scores
Nokia N91 achieved a good score of 519 points in the JBenchMark Ⅱ test. Although this is still about 40 points behind the first place 3250, its advantage over the N70 and 6630 is unshakable.
The results of JBenchMark 3D are divided into four parts: High Quality, Low Quality, Triangles/s and KTexels/s. Nokia N91 scored 201 points in High Quality, ranking second among the four mobile phones.
The final score of JBenchMark HD is also composed of four sub-items, which are: Fill rate, Textured, Smooth and Gaming. Selecting the Gaming link, Nokia N91 handed in an answer sheet of 146 points for the user. , the gap with the first place 3250 is only 7 points, which is almost negligible.
Finally, SPMarkJAVA 06 was installed for the N91. Its test is divided into two parts: Game and Feature. The former includes three parts: High Detail 3D Game Test (high-quality 3D scene), Low Detail 3D Game Test (low-quality 3D scene) and 2D Game Test (2D game scene). The latter consists of four sub-tests: 3D fill rate, polygon throughput, Video Processing, Image Processing and Java Virtual Machine tests.
N91 achieved a score of 2512 points. Nokia N91 has a built-in 2-megapixel camera with an actual effective pixel count of 1.92 million and can take pictures with a maximum resolution of 1600×1200. However, since this machine is not mainly focused on taking pictures, its software functions are relatively simple, basically the same as those used by 6681, 6630, etc., but there is a big gap with the mainstream N70, 3250, etc., let alone It's on par with the N90.
The N91’s camera software can support up to 8x digital zoom, and is equipped with three camera modes: night, continuous shooting and automatic timer, and three camera qualities of high, medium and normal. As always, framing lag is more severe in night mode. In addition, Nokia N91 also has five white balances including automatic, sunny, cloudy, incandescent and fluorescent, and four tones of normal, sepia, black and white and complementary colors. The standby time is short, the screen material is poor, the camera has no protection, and the weight is a bit heavy. Compared with Android, WP and other interfaces, the operating system of S60V3MR is slightly lacking in functionality
