Ritmix RMD-520 tablet review

In early 2012, Ritmix launched several interesting tablets on the market. Among them, the RMD-520 mini-tablet was the most memorable. Its distinguishing features are its miniature size and quite good technical characteristics, which are in no way inferior to older models: a 1.2 GHz processor, 512 MB of RAM, 8 GB of internal Flash memory, a 1.3 MP front camera, USB OTG and a capacitive display with support for up to 4 simultaneous touches.

At the moment, the RMD-520 costs 4,590 rubles, and in this price range, Ritmix will have to compete with teXet, Explay, IconBit and others.

The device will be of interest primarily to those who appreciate compact dimensions: the device can easily fit in a handbag, in jacket pockets or even in the back pocket of jeans.

Design, dimensions, controls

The tablet has an oval body shape with dimensions of 136x90x13.7 mm and a weight of 225 grams. The design of the model is reminiscent of the Samsung Galaxy Tab P1000, which, by the way, also has a white back cover. The material from which the RMD-520 is made is plastic of various types. For example, the edging is semi-gloss (black), while the back is completely glossy. In general, a fairly neat and not too strict appearance.

If you're interested, the 520 is almost a complete copy of the Yuan Dao Window N50, N50DT, N50GT, N50GT-A. You can read more about them here and here.

Fingerprints are visible only on the screen, they are erased very easily. By and large, the case is absolutely not easily soiled, and it is assembled soundly: it does not creak, does not play, does not crunch when squeezed. In about a month of operation, not a single major scratch or abrasion appeared on the surface of the display, despite the fact that Gorilla Glass or other glass is not used here.

It is better to operate the RMD-520 with two hands, however, it is comfortable to hold it in one.

There are traditional (for Android 2.3) four touch buttons on the bottom of the front panel. Apparently, the device was made before the fourth "android" appeared. Applied with white paint and not backlit.

There is a front camera, designed for video conferencing, works fine with the Skype application, but for some unknown reason, the image is very enlarged (2-3 times). On the left side there is a mechanical reset button, on the right side there is a round on / off button and volume control that extends slightly above the case.

Power input, microSD card slot, miniUSB, OTG (the last three connectors are closed with a plug) and a standard 3.5 mm headphone output are on the bottom. There is a speaker on the back. There is also a microphone.

Display

The diagonal is only 5" (physical size 118x65 mm) at a resolution of 800x480 pixels, the density is 180 pixels per inch, Kakande 16:9 aspect ratio, TFT-LCD screen matrix type.Touch layer – capacitive, supports up to 4 simultaneous touches.Touchscreen - Raydium Semiconductor RM31043.Sensitivity is not bad, but far from ideal.

As for pixelation, it is, of course, noticeable, but not striking. Higher resolution would be better, who argues, but then the cost would increase.

One of the main disadvantages of this display matrix is ​​the brightness and contrast. They are quite low: if at home or office lighting conditions it is more or less comfortable to “communicate” with the screen, then on the street the display almost completely fades, and information is perceived with difficulty, especially in sunny weather.

Viewing angles are average: when the screen is tilted towards itself (in the horizontal position of the gadget), the contrast drops slightly, colors are inverted away from itself, and brightness is slightly lost in other directions.

There is no light sensor in the device, but all device testing programs detect them - AL3006. Three-axis accelerometer (MMA8452Q) and magnetometer (AK8975) are present. In the screen settings: enable / disable auto-rotate, sleep mode (from 15 seconds to 30 minutes), select wallpaper and set the font size (small, normal, large and huge). It seemed to me that the most comfortable for normal vision is a “huge” font.

Аккумулятор

В планшете используется встроенный (несъемный) литий-полимерный (Li-Pol) аккумулятор емкостью 3200 мАч, 3.7 В. Производитель указывает следующие цифры «живучести» батареи:

  • Music playback is about 7 hours
  • Video playback is about 6 hours
  • Working on the Internet - about 6 hours

I got slightly different indicators:

  • HD video playback (720p, H.264) at maximum brightness and volume with sound output to the speaker: just over 3 hours
  • Music playback on headphones at maximum volume: just over 6 hours
  • Games only (high brightness and volume): about an hour
  • Wi-Fi surfing only (high backlight brightness): about 5 hours
  • Average battery life (two hours Wi-Fi, one hour video and half an hour toys): 4-5 hours

Unfortunately, Ritmix RMD-520 cannot be charged via USB. It will take about an hour and a half to charge from the AC adapter.

Communications

The device has a Wi-Fi 802.11 b/g/n, USB 2.0 module with data transfer rates up to 7 MB/s + On-the-Go USB host (miniUSB to USB cable included). Flash drives go without problems, by the way, the file system can be either FAT32 or NTFS.

You can connect mice (a small cursor appears on the screen), keyboards and 3G USB modems. The list can be downloaded by following this link.

If mobile Internet is used, then traffic is limited in the settings - a special feature of Android 4.0.

There is no Bluetooth wireless data transmission and GPS navigation in this model - it does not support the chipset.

Memory, memory card

The RAM in the device is 512 MB (DDR3, manufacturer - Elpida (2 x 256MB)), about 170 MB is available by default. It seems to me that for a budget tablet it is quite enough for most tasks.

The manufacturer indicates that there is 8 GB of Flash memory inside (the manufacturer is Micron), but only 500 MB is actually available for installing applications. There is a slot for a microSDHC memory card, its maximum capacity can be up to 32 GB. Hot-swappable. I tested the tablet with cards from 2 GB to 16 GB - everything was fine.

Camera

The Ritmix RMD-520 has a 0.3 MP front camera (on the manufacturer's website it says 1.3, it's not). There are no special settings, the picture quality is usually for such cameras. The camera in Skype works, the image is broadcast in normal colors, but the scale of the video is greatly increased: in order for the interlocutor to see my face, you need to hold the tablet at arm's length.

Video Features:

  • Format: MP4
  • Video codec: AVC, 700 Kbps
  • Resolution: 640 x 480, 24 fps
  • Audio codec: AAC
  • Channels: 1ch, 44.0 kHz

Performance

The tablet operates on a Chinese chipset from "Fuzhou Rockchip Electronics" - RK2918. Inside it works the ARM Cortex A8 processor at a clock frequency of 1.2 GHz, its architecture is ARMv7, the manufacturing process is 65 nm. Read more here.

Supports NEON Media Processing and ARM TrustZone technologies. Read more here.

Vivante GC800 Graphics Engine is responsible for graphics. In standard 3D games, it performs better than the Mali-400MP, but as soon as additional special effects appear, performance drops sharply. If interested, you can read this thread.

In general, the Rimix RMD-520 executes all commands relatively quickly, without slowdowns or lags.

Краткая техническая характеристика:

Тесты производительности:

Программная платформа

Планшет работает на одной из последних версий Android ICS – 4.0.3. Версия ядра 3.0.8+liqing-System, номер сборки RK29sdk-eng 4.0.3 IML74K eng.root.20120317.152732. Фирменная оболочка отсутствует. Более подробно с Google Android Ice Cream Sandwich вы можете ознакомиться здесь.

Applications

There is an Android Market for installing apps. You need to have a Google account to download. If you decide to download programs from the network and drop them into the device’s memory, then AppInstaller will come in handy. By default, the usual "Google" set is installed.

Web browser

Standard web browser Android 4.0 installed. Since the device operates on an ARMv7-architecture processor, it supports Flash. Despite the rather powerful graphics engine and not the weakest processor, the browser slows down and “draws” pages for a long time: it seems that the download is not via Wi-Fi, but via GPRS. Multitouch does not work well, the page increases in jerks. With Opera Mobile, all problems have been solved. Apparently, the version of the regular browser is still raw.

Multimedia

Music player

A familiar Android player. I will not list all its features, they are no different from the stock ICS. Audio playback formats: MP3, WAV, OGG, FLAC, APE, AAC

Speaker volume is low, but music is clearly louder than movie sound.

The volume in the headphones is very high, it is enough to "build up" any headphones. The quality pleased: deep low, pleasant mids and highs. It should be noted that most budget tablets based on Ice Cream Sandwich sound quite good.

Video Player

It supports almost all video formats and codecs: AVI, 3GP, MP4, RM/RMVB, FLV, MKV, WMV, DAT, MOV (FullHD/1080p); MPEG1/2/4, H.264 / VC-1 / XviD / DivX. In short, everything is the same as in older models. There is nothing to comment on - an excellent player, but, alas, there is no image output via HDMI to TV.

Impressions

I didn't go into too much detail about all the features of the tablet, because it is practically no different from hundreds of other low-cost devices based on RockChip, BoxChip, AllWiner, Amlogic and so on. By and large, only the appearance, types of display matrices and the presence / absence of certain connectors change.

I liked the Ritmix RMD-520 device because it has miniature dimensions (for tablets) and has a fairly good "iron" filling. It can be used both as a "reader", and as a gadget for watching videos, as well as a simple game console. The RMD-520 has practically no competitors (except for various kinds of Chinese counterparts) given the small diagonal, size and, of course, the price.

I didn't go into too much detail about all the features of the tablet, because it is practically no different from hundreds of other low-cost devices based on RockChip, BoxChip, AllWiner, Amlogic and so on. By and large, only the appearance, types of display matrices and the presence / absence of certain connectors change.

I liked the Ritmix RMD-520 device because it has miniature dimensions (for tablets) and has a fairly good "iron" filling. It can be used both as a "reader", and as a gadget for watching videos, as well as a simple game console. The RMD-520 has practically no competitors (except for various kinds of Chinese counterparts) given the small diagonal, size and, of course, the price.

Ritmix RMD-520 tablet review

In early 2012, Ritmix launched several interesting tablets on the market. Among them, the RMD-520 mini-tablet was the most memorable. Its distinguishing features are its miniature size and quite good technical characteristics, which are in no way inferior to older models: a 1.2 GHz processor, 512 MB of RAM, 8 GB of internal Flash memory, a 1.3 MP front camera, USB OTG and a capacitive display with support for up to 4 simultaneous touches.

At the moment, the RMD-520 costs 4,590 rubles, and in this price range, Ritmix will have to compete with teXet, Explay, IconBit and others.

The device will be of interest primarily to those who appreciate compact dimensions: the device can easily fit in a handbag, in jacket pockets or even in the back pocket of jeans.

Design, dimensions, controls

The tablet has an oval body shape with dimensions of 136x90x13.7 mm and a weight of 225 grams. The design of the model is reminiscent of the Samsung Galaxy Tab P1000, which, by the way, also has a white back cover. The material from which the RMD-520 is made is plastic of various types. For example, the edging is semi-gloss (black), while the back is completely glossy. In general, a fairly neat and not too strict appearance.

If you're interested, the 520 is almost a complete copy of the Yuan Dao Window N50, N50DT, N50GT, N50GT-A. You can read more about them here and here.

Fingerprints are visible only on the screen, they are erased very easily. By and large, the case is absolutely not easily soiled, and it is assembled soundly: it does not creak, does not play, does not crunch when squeezed. In about a month of operation, not a single major scratch or abrasion appeared on the surface of the display, despite the fact that Gorilla Glass or other glass is not used here.

It is better to operate the RMD-520 with two hands, however, it is comfortable to hold it in one.

There are traditional (for Android 2.3) four touch buttons on the bottom of the front panel. Apparently, the device was made before the fourth "android" appeared. Applied with white paint and not backlit.

There is a front camera, designed for video conferencing, works fine with the Skype application, but for some unknown reason, the image is very enlarged (2-3 times). On the left side there is a mechanical reset button, on the right side there is a round on / off button and volume control that extends slightly above the case.

Power input, microSD card slot, miniUSB, OTG (the last three connectors are closed with a plug) and a standard 3.5 mm headphone output are on the bottom. There is a speaker on the back. There is also a microphone.

Display

The diagonal is only 5" (physical size 118x65 mm) at a resolution of 800x480 pixels, density - 180 pixels per inch, Kakande aspect ratio 16:9, screen matrix type TFT-LCD. Touch layer - capacitive, supports up to 4- x simultaneous touches.Touchscreen - Raydium Semiconductor RM31043.Sensitivity is not bad, but far from ideal.

The touch layer is capacitive, supports up to 4 simultaneous touches. Touchscreen - Raydium Semiconductor RM31043. Sensitivity is good, but far from perfect.

As for pixelation, it is, of course, noticeable, but not striking. Higher resolution would be better, who argues, but then the cost would increase.

One of the main disadvantages of this display matrix is ​​the brightness and contrast. They are quite low: if at home or office lighting conditions it is more or less comfortable to “communicate” with the screen, then on the street the display almost completely fades, and information is perceived with difficulty, especially in sunny weather.

Viewing angles are average: when the screen is tilted towards itself (in the horizontal position of the gadget), the contrast drops slightly, colors are inverted away from itself, and brightness is slightly lost in other directions.

There is no light sensor in the device, but all device testing programs detect them - AL3006. Three-axis accelerometer (MMA8452Q) and magnetometer (AK8975) are present. In the screen settings: enable / disable auto-rotate, sleep mode (from 15 seconds to 30 minutes), select wallpaper and set the font size (small, normal, large and huge). It seemed to me that the most comfortable for normal vision is a “huge” font.

Battery

The tablet uses a built-in (non-removable) lithium-polymer (Li-Pol) battery with a capacity of 3200 mAh, 3.7 V. The manufacturer indicates the following figures for the "survivability" of the battery:

  • Music playback is about 7 hours
  • Video playback is about 6 hours
  • Working on the Internet - about 6 hours

I got slightly different indicators:

  • HD video playback (720p, H.264) at maximum brightness and volume with sound output to the speaker: just over 3 hours
  • Music playback on headphones at maximum volume: just over 6 hours
  • Games only (high brightness and volume): about an hour
  • Wi-Fi surfing only (high backlight brightness): about 5 hours
  • Average battery life (two hours Wi-Fi, one hour video and half an hour toys): 4-5 hours

Unfortunately, Ritmix RMD-520 cannot be charged via USB. It will take about an hour and a half to charge from the AC adapter.

Communications

The device has a Wi-Fi 802.11 b/g/n, USB 2.0 module with data transfer rates up to 7 MB/s + On-the-Go USB host (miniUSB to USB cable included). Flash drives go without problems, by the way, the file system can be either FAT32 or NTFS.

You can connect mice (a small cursor appears on the screen), keyboards and 3G USB modems. The list can be downloaded by following this link.

If mobile Internet is used, then traffic is limited in the settings - a special feature of Android 4.0.

There is no Bluetooth wireless data transmission and GPS navigation in this model - it does not support the chipset.

Memory, memory card

The RAM in the device is 512 MB (DDR3, manufacturer - Elpida (2 x 256MB)), about 170 MB is available by default. It seems to me that for a budget tablet it is quite enough for most tasks.

The manufacturer indicates that there is 8 GB of Flash memory inside (the manufacturer is Micron), but only 500 MB is actually available for installing applications. There is a slot for a microSDHC memory card, its maximum capacity can be up to 32 GB. Hot-swappable. I tested the tablet with cards from 2 GB to 16 GB - everything was fine.

Camera

The Ritmix RMD-520 has a 0.3 MP front camera (on the manufacturer's website it says 1.3, it's not). There are no special settings, the picture quality is usually for such cameras. The camera in Skype works, the image is broadcast in normal colors, but the scale of the video is greatly increased: in order for the interlocutor to see my face, you need to hold the tablet at arm's length.

Video specifications:

  • Format: MP4
  • Video codec: AVC, 700 Kbps
  • Resolution: 640 x 480, 24 fps
  • Audio codec: AAC
  • Channels: 1ch, 44.0 kHz

Performance

The tablet operates on a Chinese chipset from "Fuzhou Rockchip Electronics" - RK2918. Inside it works the ARM Cortex A8 processor at a clock frequency of 1.2 GHz, its architecture is ARMv7, the manufacturing process is 65 nm. Read more here.

Supports NEON Media Processing and ARM TrustZone technologies. Read more here.

Vivante GC800 Graphics Engine is responsible for graphics. In standard 3D games, it performs better than the Mali-400MP, but as soon as additional special effects appear, performance drops sharply. If interested, you can read this thread.

In general, the Rimix RMD-520 executes all commands relatively quickly, without slowdowns or lags.

Software platform

The tablet runs on one of the latest versions of Android ICS - 4.0.3. Kernel version 3.0.8+liqing-System, build number RK29sdk-eng 4.0.3 IML74K eng.root.20120317.152732. There is no proprietary shell. You can read more about Google Android Ice Cream Sandwich here.

Applications

There is an Android Market for installing apps. You need to have a Google account to download. If you decide to download programs from the network and drop them into the device’s memory, then AppInstaller will come in handy. By default, the usual "Google" set is installed.

Web browser

Standard web browser Android 4.0 installed. Since the device operates on a processor with ARMv7-architecture, work with Flash is supported. Despite the rather powerful graphics engine and not the weakest processor, the browser slows down and “draws” pages for a long time: it seems that the download is not via Wi-Fi, but via GPRS. Multitouch does not work well, the page increases in jerks. With Opera Mobile, all problems have been solved. Apparently, the version of the regular browser is still raw.

Multimedia

Music player

A familiar Android player. I will not list all its features, they are no different from the stock ICS. Audio playback formats: MP3, WAV, OGG, FLAC, APE, AAC

Speaker volume is low, but music is clearly louder than movie sound.

The volume in the headphones is very high, it is enough to "build up" any headphones. The quality pleased: deep low, pleasant mids and highs. It should be noted that most budget tablets based on Ice Cream Sandwich sound quite good.

Video player

It supports almost all video formats and codecs: AVI, 3GP, MP4, RM/RMVB, FLV, MKV, WMV, DAT, MOV (FullHD/1080p); MPEG1/2/4, H.264 / VC-1 / XviD / DivX. In short, everything is the same as in older models. There is nothing to comment on - an excellent player, but, alas, there is no image output via HDMI to TV.
