00:00This year the Samsung company introduced several devices to the Galaxy A,
00:04their phones of media range.
00:06With them, the South Korean company promised
00:09improvements in terms of cameras, batteries and photography cameras,
00:13without sacrificing the pocket of users.
00:16Here in Tecnoespectador, we could compare the A21s with the A31,
00:21two devices that are already in Colombia
00:22and that can be quite similar to first sight.
00:25But, which is better?
00:38A nivel estético, the A21s and the A31s are quite similar.
00:44The two have the borders marked and the same photographic camera,
00:48in which there are four cameras.
00:50Both have the jack of 3.5mm for the auriculars and have a single speaker,
00:55so we don't have stereo stereo or a volume particularly high in any of the two devices.
01:02The front camera of the A21s is on the left side,
01:07which allows us to take a little bit of the screen
01:10while the A31 has a lower notch located in the center.
01:14In terms of dimensions, the A21s is bigger, with 163.7mm and 8.9mm of height,
01:23while his brother has 159.3mm of height and 8.6mm of height.
01:29In that sense, the A31s is more compact, more light and much more portable than the other device.
01:36Another thing that diferencia in terms of design is that the A21s has a sensor in the left side,
01:41while the A31s has a sensor in the left side.
01:44Now, we saw that the sensor in the left side was much faster than the left side of the device,
01:49which in this case gives more points to the A21s.
01:53In terms of the face, both of them were very similar,
01:56although more fast than the A31s.
01:59Both phones have 5.000mAh batteries, which is quite good for a medium range.
02:05The duration was practically the same.
02:08Bajo a constant use and making several shots of photography and video,
02:12both over the day and a half without a problem.
02:14In addition, both of them have a rapid charge of 15W,
02:17so they took almost the same time to be completely removed.
02:20In the first device, we found a Exynos 850 processor,
02:24which is focused on the better use of the battery
02:26and to support the cameras with high resolution.
02:30On the other hand, the A31 comes with the MediaTek Helio P65,
02:34which is also thought to give a good performance
02:36to the cameras and enhance those tasks that have to do with artificial intelligence.
02:41In comparison, we can say that both processors
02:43were designed for medium-sized devices.
02:46In terms of memory,
02:47although both of them have 6GB RAM and 64GB of internal storage,
02:52the A21s can be expanded to 512GB,
02:56while the A31 can only do it at 128GB.
03:00One of the main differences is that we find in the screens of these devices.
03:04The A21s has a display of 6,5",
03:07and although it has a good range of light and a good balance of blancs,
03:11it shows images much more cold than the A31.
03:14Also, the colors are not so saturated,
03:17and there are no high contrasts.
03:19The A31 is of 6,4", and Full HD,
03:22which allows us to see the colors with a greater intensity and definition,
03:27since they have a greater range of pixels.
03:29In the photograph,
03:30both of them are a little bit different in terms of resolution,
03:33but both can offer good images.
03:35When we test them,
03:36we saw that, again,
03:37the most important change in terms of color.
03:40The A31 gives images with more intense colors,
03:43and also includes an optimizer of scenes that the A21s does not have.
03:47In some cases,
03:48the A21s can capture more details,
03:51and although its tones are more opaque,
03:53it can bring results more realistic,
03:55so that at the end,
03:56everything will depend on the preferences of the user.
03:59In the macro lens,
04:00we have to say that
04:01there is no one of them in any of the two devices.
04:04Although the A31 allows us to 5 megapixels,
04:08which is a little more if compared with the A21s,
04:11the A21s has to be very close to the object
04:13to achieve good shots,
04:15and even so,
04:16we can see the recording of the AI,
04:18so that sometimes,
04:20it will be better to use the zoom.
04:23In both devices,
04:24it reaches to the 8x,
04:25which, although it is not surprising,
04:28it is good for the daily photos.
04:30In terms of the lens,
04:31both phones got good images,
04:34however,
04:35it is just in these images,
04:37in which the A31 resaltates a little more
04:39for the intensity of its colors.
04:41However,
04:42none of the two devices have nocturned,
04:44the flash of both phones got good results.
04:46But, above all,
04:48the A31,
04:49which was able to save more colors
04:51than the A21s.
04:52The front camera of both devices
04:54also gave us good results.
04:56The A21s is of 13 megapixels,
04:59while the A31 is of 20,
05:01so, in this last one,
05:03we can see a little more detail.
05:05In terms of dynamic dynamic
05:06that allows us to focus on the front,
05:08we received quite a few results
05:10and the main features were kept
05:11as the main features.
05:13Like other brands,
05:14both devices can change the effect
05:16in photos that were already taken
05:18before.
05:19In terms of video,
05:20there is no much difference
05:21between both devices,
05:22except in the tones of the scenes.
05:24No one of the two
05:25comes with a stabilizer
05:27and with a camera lenta
05:28or rapid,
05:29but both devices can be recorded
05:31in HD and Full HD.
05:33In conclusion,
05:35both Samsung phones
05:36are directed to people
05:37who don't need so much
05:38but want to take good photos
05:40and appreciate a good battery.
05:43In that sense,
05:44there is a good improvement
05:45in this line.
05:45For us,
05:46the winner is the A31.
05:49It has a little more
05:49resolution than his brother
05:51when taking photos.
05:52It contrasts better the colors,
05:55it is more portable
05:55and it has a better screen.
05:57It is more expensive.
05:59It is more expensive.
06:00than the other one.
06:01It is about $1.149.000.
06:04The A21s also has its advantages,
06:08as well as a better
06:08advantage of the screen,
06:10a better screen reader
06:11that is more fast
06:12and the possibility
06:13of having more
06:14almacenamiento interno,
06:15which many of you will
06:17certainly appreciate.
06:17It is also a bit more
06:19than the A31.
06:20In Colombia,
06:21the price suggested
06:22by Samsung
06:23is $782.900.
06:26This is the video of today.
