Comparing Jelly 2 with Jelly Pro and Atom When comparing Jelly 2 with iPhone SE (2nd generation) and Pixel 4a, it feels a little nostalgic in terms of design, but Unihertz also has Atom and " The Jelly Pro had a pretty toy feel, but the texture of the Jelly 2 has improved considerably, as the products have been successfully developed with the Titan, Atom L, and Atom XL and shipped safely. Of course, the exterior is plastic and it doesn't look luxurious, but considering the amount of investment, it should be enough. There is only one color, black, but it is quite fashionable that the back is slightly bluish and very dark navy blue rather than pure black. In addition, the customized key mounted on the side, which has become a feature of Unihertz, is also painted in red metallic, giving it a nice taste as an accent. The back of Jelly 2. There is a rear camera, LED flash light, fingerprint sensor, Osaifu Keitai logo (antenna), Unihertz logo. The main specifications are MediaTek chipset (SoC) "Helio P60" and 6GB internal memory (RAM), 128GB internal storage, microSDXC card slot, 2000mAh battery, USB Type-C terminal, 3.5mm earphone microphone terminal, Wi-Fi 5, Bluetooth 4.2, NFC, infrared remote control, location information acquisition (GPS etc.), FM radio, Android 10 etc. The rear camera has a single configuration of approximately 16 million pixel CMOS / wide-angle lens (F1.7). The sensor is equipped with ambient light, acceleration, gyro, proximity, and electronic compass. The mobile phone network supports LTE Category 4 with a maximum downlink speed of 150 Mbps and a maximum uplink speed of 50 Mbps, and supports VoLTE. The supported frequency bands are as follows. Left and right sides of Jelly 2. The power key and customization key, nanoSIM card (4FF) and microSDXC card slots, USB Type-C terminal are located on the right side, and the volume up / down key is located on the left side. One of the card slots is for nanoSIM cards, the other is nanoSIM. It is shared by the card or microSDXC card, and supports dual SIM dual VoLTE (DSDV) when two nanoSIM cards are installed. The top and bottom sides of Jelly 2. Infrared remote control port, 3.5mm earphone microphone terminal, sub microphone, external speaker and microphone are arranged on the upper side There is no strap hole on the main body, but the attached strap can be attached to the attached clear case In Japan, it can be used by NTT DoCoMo, au, Softbank and their virtual mobile network operators (MVNO), and it can also be used by Rakuten Mobile's Rakuten UN-LIMIT V. In addition to being listed on the official operation check models of Mobile Suica and Mobile PASMO, Osaifu-Keitai can also be used with "iD" etc. at hand, and if you install Google Pay, you can easily make touch payments with a non-contact IC. increase. On the contrary, I don't want to try it, but I'm worried that code payment can be used because the screen is small. After the initial settings are completed, the home screen is 3 screens + Google Discovery, and among the pre-installed apps, the basic screen saver, remote control fairy, and calculator can be uninstalled. The setting screen and device information. The user interface (UI) is almost like Android. The build number is "Unihertz_Jelly2_JP_20200723", which is unique to the product for Japan, which is a concern when considering future software updates, but the difference is only in the Osaifu Keitai, so it's probably okay. Technical suitability mark (certification number) As previously announced, the technical standard conformity certification (R) based on the Radio Law is "210-146063", and the technical standard conformity certification (R) based on the Telecommunications Business Law is "ADF20-00005210". The built-in storage feels like there is nearly 120GB of free space. The customize key on the right side can be set to 3 types: press once, press and hold once, and press twice. Customized keys can be set by each app in addition to special functions such as taking screenshots. In addition, the camera function can be set by pressing the Android standard power key twice, so there is no need to use the customize key. The left is the pre-installed application "Remote Control Fairy" for using the infrared remote control function, and the Sony TV at home. Was usable normally. In addition, FM radio properly supports around 80MHz, which is the main frequency band in Japan, and has a recording function. If you want to use FM radio, you need to attach earphones to the 3.5mm earphone / microphone terminal. It also supports automatic recording of voice calls, and the recorded calls are saved as voice files in the "Phone Record" folder of the internal storage. It has been. Power on / off can be continued according to the schedule. Voice recorder (image = left) and various tool apps (image = right). Compass, pedometer, heart rate monitor, protractor, flashlight, etc. can be used. The flashlight that keeps the LED flashlight on is assigned by pressing and holding the customized key key by default. The camera is simple but also supports professional mode, and it is also possible to mute the shutter sound by setting. In addition, it seems that the screenshot sound cannot be erased. I set iD with the Osaifu-Keitai app and the added Google Play. Mobile PASMO can be relatively easily migrated by linking with a Google account, so I would like to use it soon. For the time being, I will post the result of "Geekbench 5" as a benchmark. In the single core, it is equivalent to the Helio P65 (MT6768V) installed in the "Galaxy A41" etc. and the Snapdragon 662 installed in the "OPPO A73" etc., and the score was higher in the multi-core Jelly 2 is a spec It seems that it has improved and became more practical, and because of the Corona Snapdragon, I don't go out much, so if I usually use a computer or tablet at home and do not play games on my smartphone, I will go out a little. Then I feel that this is enough. It doesn't have a battery compared to a big screen smartphone, but it's better than a Jelly Pro, and it seems that it will last for a day if it's mainly in standby mode. However, Jelly Pro was able to replace the battery, but Jelly 2 can not, so if you are worried about battery life, will you have to prepare a mobile battery etc.? Of course, I usually carry multiple smartphones with me, so do I need Jelly 2? It's difficult to answer when asked, but it's small and cute, and for the time being, I'd like to keep it in my room pocket as an infrared remote control. Also, above all, it is big that it finally supported Osaifu-Keitai that Atom could not support, and it costs only +20 dollars (about 2,000 yen) compared to overseas products, so it is compatible with Osaifu-Keitai of a certain major manufacturer. I even wonder what it was like to cost 10,000 yen. Of course, in the case of Jelly 2, it is crowdfunding and it may be as close to the cost as possible, but it is denied that this price difference is the first product to be supported, and that other major manufacturers also cost 10,000 yen. It seems that it is only negligent to not support Osaifu-Keitai in terms of cost, and I even feel that I do not want to purchase products from such manufacturers.
