And the Weibo war is on! Onda lobs more than one missile back at Teclast.
That goes to a QQ page where Onda says Teclast’s accusations are “fabricated” and that users aren’t stupid, have praised the V919 3G Air they’ve purchased, and that the tablet is outselling other brands [Google Translate]. Let me say that’s a somewhat weak defense. Even in America we know of sockpuppets leaving paid-for “reviews” on sites. And sales say nothing about returns.
But there’s more.
And the link there goes to the OndaBBS, where someone who purports to be an “electronics designer” compares the dual-OS Onda V820w to two unspecified dual-OS Teclast tablets [Google Translate]. The tone, even in translation, is rather reasonable:
Onda V820w dual system is the use of INSYDE the BIOS, because of living in the electronics industry, this business is very familiar with, which is a focus on the development of Taiwan underlying system embedded device companies, many international companies, such as Hewlett-Packard, Dell, Lenovo will use this system’s BIOS, stability and advancement goes without saying.
The T brand is using the AMI BIOS, honestly speaking, AMI is also regarded as a veteran of the BIOS system vendors, on a single system with a flat, stability is definitely trustworthy. However, the current dual system technical point of view, AMI has clearly lagged behind INSYDE BIOS system, I think this is the reason Onda tablet abandoned AMI and choose INSYDE dual system. AMI system with dual INSYDE largest technical difference is that, INSYDE can achieve a key switch in the system, it is very easy to switch, switch fast. The AMI must pass again switch to switch, the operation is more complicated.
And doubt is sowed over how the AMI process used by Teclast could possibly shorten the life of the components:
In addition, people who engage in electronic know, electric and electronic products in the boot process, there will be a surge current, the original electronic devices, but a killer, after a period of time used electronic products, components begin to age, experience a power-surge, it will lead to burn components. Just switching from a dual system process see, Onda V820w dual system no matter how many times the switch, only need a boot action, while T switch cards only once have turned twice, which is equivalent to use in the same environment, T brand electronic components, it will more than double system V820w startup inrush current withstand twice the impact, the more the number of switching frequency of the impact of the higher risk of failure of the machine, the higher lifetime use of exponentially level drop.
As for the revelation that the V919 3G Air has only one speaker yet two speaker grilles, this claim is made:
First, each product specifications are not the same, T brand has two horns, others one speaker called jerry? Almost no basic knowledge of acoustics, audio quality, not the speaker of the numbers, but to optimize the output of the circuit, and the design of the sound chamber. It is because aside a larger sound chamber space, in order to ensure sound output. Besides in the 8-inch tablet is so small, you can hear the left and right speakers symmetrical design, hear the stereo? It’s not what you fooled? . This volume on the quality of judgment, a good interpretation of the idiom cheating.
That seems to me like an admission that the Onda V820w also has one speaker! I find the claim of “more room” equaling better sound from a single speaker to be difficult to believe. If you show two speaker grilles, you should have two speakers. That’s what a customer is led to believe is inside by the two grilles. Anything else is just fraud.
Two other issues are refuted.
First, an accusation is lobbed at Teclast of an improperly shielded board, with Teclast using hidden layers of tape not shown in their comparison video. This is plausible as an exhibit in the next Weibo link will illustrate.
Second, Teclast’s accusations of improper welding are claimed to be without merit. The type of weld (solder? glue?) depends on the type of printed circuit board (PCB) being used. That’s entirely plausible.
The link again goes to the OndaBBS [Google Translate]. Instead of a video, Onda chose to refute Teclast with photos.
First, Onda shows that Teclast connects their battery to the PCB with soldered wires. Onda uses a proper connector. Onda wins here. A connector should always be used.
Second, this is Onda’s nuke at Teclast:
T brand X98 tablet dual system, on the left, is insulating tape, conductive tape tightly wrapped in several layers, open to see what is hidden below.
Carefully open a layer after layer of tape, densely covered under the original display, touch screen, camera, buttons and ribbon cable and WIFI antenna, in order to save costs, in total disregard of the high-frequency circuits and interference, all cables together, and cable and doing fine, so very easy to cause interference data, the impact of operational stability plate. In order to avoid interference signals, short circuit caused by a hand-Walled board actually posted a four-tape, plus a 2mm thick cotton dust, see this unreasonable wiring and assembly methods, he could feel an intense flavor and cottage come, what Jin its tables, its foul inside, this is the most realistic portrayal.
In contrast, Onda claims the way it’s done with the V919 Air 3G is:
V919 3G AIR dual system tablet, only a simple main and auxiliary cable and a display board cable, cable for wide bars gilded line body, gold-plated material both to ensure the signal transmission process will not decay, wide strip cable, and scattered trace layout is also very good solution to the problem of high-frequency interference signals. Whole flat interior looks simple, neat, structured.
Third, Onda points to Teclast’s touchscreen chip interface being a two-year-old method that isn’t soldered directly to the PCB as Onda’s is.
Fourth, that mess of wires over the battery? Hold onto your hats for this one.
Onda claims this is wire Teclast’s WiFi, Bluetooth, and 3G antenna:
Part of the red box on the map, you do not know the students did not pay attention, actually there are two similar cables from the fly line T brand X98 tablet dual system and over the air, turned out to be the flat WIFI, Bluetooth antenna and 3G antenna.
And that this mess in the Onda tablet is justified:
But V919 3G AIR dual system tablet, also with 3G and WIFI, Bluetooth, why I can not find this two fly line? The original V919 3G AIR dual system tablet hardware engineer came out on top, had admitted to these antenna wiring board, so you can be good to avoid the production process, because the workers will not weld level, flat wireless signal causes instability human factors. Comparing two flat motherboard design, the level could not be clearer!
So they’re the antennas! And in contrast to Teclast, they’re using connectors and were placed that way as a decision to make production easier and with a higher degree of quality control. Is that plausible? I don’t know. But I’ve never seen it done that way with a global brand name.
Fifth, Onda then shows that the Teclast tablet uses just four screws to secure its screen, versus Onda’s six. Onda claims this adds stability and fewer screws risk the screen being deformed by stress.
Finally, Onda points out Teclast uses just two screws to fasten the interior PCB, while Onda uses five. Given their PCB designs are so different, I just don’t know.
So, does anyone win here? Are we looking at serious issues in the Teclast, corners cut, or Teclast and Onda’s designs really being too different to compare?
I have to say that it seems to me Teclast is being cheap by affixing the battery wires with solder instead of a connector. Even if both the Teclast and Onda tablets aren’t meant to have long lives, at least Onda using a connector shows some respect for users and repair technicians.
I don’t think Teclast should have started this war. Onda has managed to point out things about Teclast’s assembly methods that I don’t think Teclast wanted known.
