hello,

I want to buy one of these tablets ...

But I do not want to read all 276 pages of this Topic.

On some website I see that the Teclast Air II have GPS, on other sites, no!

But which one do you recommend? AIR 3G or AIR II ? did not need the 3G, but the GPS interests me for android. Does GPS works on Windows?

So can you confirm that the Air II is better?

Thx

As many of you I have bought the tablet to Anna Fang on aliexpress and I have received with a dispute the agreement to send back the tablet for a change. My question now is, independently from the shipping that cost a lot,

the thermal issue could be happens on the tablet that will be replaced, it this a hardware problem of the X98 Air 3G that could be always confirmed on all the production?

This morning I have started the Asphalt 8 with CPU a 22 C and for the first time I have completed a circuit but with the temp a 49 C so I have closed the game and I have restarted again with the temp of 40C after fews second the temp

raises to 50 and the tablet freeze.

Do somebody has tablet without the thermal issues ?

Tks Fred
[Teclast X98 Air 3G] severall:
CPU in my Teclast warm up to 75C and no freezeing or restarting. These problems seems to be more complex then we think..
[Teclast X98 Air 3G] soudara:
I think is the quality of ddr ram

i customized thermal setup with alluminium plate and thermal past , i win 5° in full load 58° maximum with asphalt overdrive but crash after 15mn , i test with underclock cpu with setcpu free at 1500mhz same problem after 15mn crash i can see in cpu temp graphic my cpu locked at 1500mhz in full load in game but not change anything , i think the probleme is ram quality depending on tablet
[Teclast X98 Air 3G] trikst3r:
x98 AIR II does not have 3G or GPS.

x987 AIR 3G has both. GPS works on windows, you don't need to install any drivers for that.
[Teclast X98 Air 3G] Hendrickson:
The lucky of the draw when you get these tablets. I think a couple of thermal pads on the soc to connect to the metal rear housing is all that would be needed to help out with the heat. Maybe just a few on the ram and soc. I don't think the eMMC will need one.

I'm going to do this if I can recover my bios bricked my Air 3G.

i dont use google play almost at all, only when it is very critical situation i use.. so i didnt notice. bot for this retina screen and resolution, the best dpi setting is 264dpi

Instead of reboot, switch the tablet OFF and on powerOn you'll see the menu ;)

LOL so you don't want to read ALL the pages... interesting way to start asking i'm afraid...
[Teclast X98 Air 3G] mohamad_skiller:
keep vol + and power you can see boot option
[Teclast X98 Air 3G] SUMMERBREEZE:
Thank you very much for your thoughts, they are really helping me.

After i read your comment, i changed my mind a bit. I am thinking to use a Heatsink Plaster Thermal Conductive Glue instead of Arctic Silver.. As you said the copper heatsinks should not move at all so the best option is a kind of thermal adhesive glue as on the link.. It will be between chips and copper heatsinks and make them more stable, so it will be more safer.

And on the metal lid of SOC and between it and backcover of the tablet, i better use something soft as you said, not copper. maybe SOMETHING LIKE THIS :confused:

If i use something very hard and not the right thickness, the cover will not close.

I am not very sure about between the circuit board and touchpanel(the backside of the chips, undet the soc unit) what kind of material and how much thickness? MAYBE THIS ONE AGAIN

The thing is, my tablet is working in IDLE around 40-42 degrees but others tablets almost half of it (24-25 degrees) thats why i think i need an intensive solution, this is the only reason i am thinking of the copper heatsinks.
[Teclast X98 Air 3G] grigoris_a:
A clarification about dual booting.In the dual boot screen in the top left there is a small windows and android icon with a tick next to them.If we untick this and choose an operating system(android or windows) then the dual boot menu will not appear again as the chosen system to boot at that time becomes the default.If we want dual boot screen to show again than when we boot the tablet we keep holding the vol up key pressed.

hi

when i connect hands free(with mic) to my tablet i cant hear singer just can hear music with awful quality

but when i connect earphone(with out mic) i havent any problem?

is there anyone here have the same problem?

How I can make it work fester? Interface is very slow. Air 3g. 2.00.
[Teclast X98 Air 3G] PWMx:
Read previous posts .. or better use search.

Your handfree+mic is with wrong 3.5mm pin out. This tablet implements OMTP pin out.

(Ground and mic line are in opposite order.)
[Teclast X98 Air 3G] krisbliz:
To be honest i dont have idea. Always when i install windows i turn off auto updates, but this time i was so obsessed with this tablet and forgot to do it, so all the updates were installed automatically, i also installed the battery bar so maybe that software fixed the problem. The battery meter reading are ok so far.
[Teclast X98 Air 3G] Jiri_S:
You can try use 1 mm silicone pad but I'm afraid that there isn't space (between back lid and SOC cover) for that - I think that this will be enough.

I did not address the gap between PCB and display because the pad underneath the lid pressed the PCB on the back of display.
[Teclast X98 Air 3G] SUMMERBREEZE:
1) root your device

2) get rid of all chinese and unneccesarry apps, even some system apps. Uninstall them by using an root explorer or root manager app.

3) change the home launcher, maybe NOVA or APEX launcher.

4) change the screen DPI setting to 264ppi

there are the most important 4 things to do in the beggining..

if still not satisfied, JUMP TO WINDOWS 8.1 WORLD :D
[Teclast X98 Air 3G] pcbroute:
What battery bar?

I can try it to)
[Teclast X98 Air 3G] krisbliz:
I downloaded the free version from http://batterybarpro.com/

Try and reply.

Thanks
[Teclast X98 Air 3G] mohamad_skiller:
ive tested my tablet with cpu temp and i get 45-47c in idle and in max load got to 67_70c

i think i dont have freeze problem i played game with wild blood more than 6 hours but it never happen crashing or feezing while i was playing

and i tested dead triggers and fifa 15 and nfs most wanted but i dont have problem except 1 or 2 times after playing 2or 3 hours in wildblood i got freeze for 2 times

but i love this game and i played this game more than 50 to 60 hours and ive got crashed just for twice

but i couldnt download rr3 to test my gpu

and i cant say i dont have problemtic soc until that i ve test rr3
[Teclast X98 Air 3G] noob.noob:
Win 8.1 really fester then Android ?
[Teclast X98 Air 3G] SUMMERBREEZE:
Thank you Jiri, i found THIS ONE, much cheaper and also specs looks better. I will try to use it also under the circuit board.

i will cut 40mm x 100mm size of the pad and place it under the pcb(just under SOC unit and also it will cover 3G cellular metal can and sd card metal can)

and the rest of the pad, i will cut it as the shape of SOC metal can and place it between back lid and SOC cover. And shee the results. Hope it will worth doing :)
[Teclast X98 Air 3G] pcbroute:
i install it and nothing happened.

is still 7% and 14432 mWh

Can someone give me link to chinese Vroot?
[Teclast X98 Air 3G] Gall Anonim:
Hi!

I've been following this thread for few weeks. I'm happy owner of model C6J6 - it doesn't hang or freeze in Dead Trigger (playing on high settings for more than 30 minutes without overheating issue - just "throttling" message appears) and also in Real Racing 3 :) Now I'm planning to flash it with dual boot bios and I got few questions:

1) How much disk space takes Win 8.1 (modificated by supercowz)? I'm curious because I don't know which version of table scheme (4 or 8GB) should I use... Is 4 GB enough to normally use Android without worrying about free space while using app2sd?

2)If I want to reinstall Windows I have to reflash tablet with Android lite image and then install Windows?

BTW Thanks supercowz, mohamad_skiller, ro11er and Frontier which makes that dual boot come true on our tablets ;)
[Teclast X98 Air 3G] francescoliberti:
hello, if I change the DPI after the play store some app like dead trigger or real racing say they are not compatible
[Teclast X98 Air 3G] tumich91:
Man, if someone will fix 48Hz refresh rate I will put his nickname on my forum signature :D
[Teclast X98 Air 3G] LVL91:
I should not have said stuff about illegal software, I could have known... (being a moderator myself on another forum)

I want to say sorry that I have said stuff about illegal software, I should not have done that.

Sad thing about it, is that my post has been completely wiped instead of edited. So again to darkosims:

Search for a winbond chip(Google winbond for possible logo's) with "25" in its name.

Most of the time it's a 8 pin chip. You should be able to flash the bios (bin file) to the chip using a programmer. Chips from winbond are used a lot to store a bios.

Ok. about the 48Hz issue. The problem could be related to the touchscreen malfunctioning.

What you see very often is that they did not properly protect the entire tablet from all frequencies.

What you might see is a flickering screen, a touchscreen which is malfunctioning, or other stuff that refreshes at around the rate of 60Hz could be a problem. Probably bad design, but I must say I don't mind it at all.

I love this tablet with windows and intend to use it a lot.

The camera problem is very annoying, that is just a very bad driver. But it's software so it could be fixed, I don't think it's bios related. It would be very stupid to create the configuration in the bios, which is a very delicate part in your computer which should not be changed. Maybe it's driver config related. I can take a look at it.
[Teclast X98 Air 3G] Hendrickson:
I've noticed something interesting, that in the My PC properties it says limited touch support with 10 touch points. Why does it say limited touch support I wonder? My Asus T200TA say's full touch support.

Also I have notice that my X98 Air 3g has started to slow down a bit, Chrome and IE11 seem to be more stutter and laggy. Not sure why. I have trimed the eMMC drive and done as much as I can to make it as fast as possible, but it seems to be slowing down a bit a lagging more. Anyone else noticed this after using it for a few weeks?
[Teclast X98 Air 3G] BoORDeL:
Wiped away evrything.

Android image should recreate evrything (referring to partition.tbl file).

Am I wrong?

Anyway windows recreate 3 hidden partitions ( one those is about 4 GB).
[Teclast X98 Air 3G] keepfishes:
I think what the guys on the Chinese forum meant to say was that if you have a working standard camera app, other camera apps that you use will be rotated. If you have a working image on other apps, you will have a problem on the standard camera app.

Thanks, I have read through those posts and I think its confusing because they are two separate issues.

1) There is one batch of tablets with faulty screens and GPUs, that do not refresh quickly enough so that scrolling is an issue. Using a touch screen software, you can see that the vertices on the screen when a line is drawn is much less than that of a normal screen.

2) The other problem is that of the refresh rate of the display itself (not of the touchscreen) which seems to affect all tablets which is likely to be a GPU driver issue (not of the hardware GPU itself).

I'll see what I can find on the chinese forum and update accordingly...
[Teclast X98 Air 3G] tumich91:
maybe you get affected by virus? have antivirus?
[Teclast X98 Air 3G] ambrosio5:
Yes I understand, a full clean install after you deleted all partitions. it's just that the original teclast image created overall 4 partitions (100mb EFI, 128mb System, Windows and a 4,6gb for windows Images). For the 2nd one 128mb system I'm not sure it's recreated my a full clean install.... and I don't know if it was useful in any way.... Also I don't thing I'll keep the 4gb partition.
[Teclast X98 Air 3G] severall:
Does anybody has a problem in Win 8,1 that sound button sometimes stop working? Only reboot can fix this.
[Teclast X98 Air 3G] BoORDeL:
I've played too much with cam.

Now evry time i try to use app i got BSOD :|.

Done a clean install and problem persist.

Now i think it's an hardware problem.

I mentioned a few posts back that the windows bing with drivers package offered for Windows installation was identified as having a Trojan by my BitDefender antivirus software.

Can you check your installation and can others also check the download packages? Viruses can degrade performance quite a bit.
[Teclast X98 Air 3G] BoORDeL:
Solved by resetting BIOS configuration and reinstalling windows without importing configurations from hotmail account.
[Teclast X98 Air 3G] keepfishes:
By "solved" do you mean that the problem of the image being inverted is gone?

---------- Post added at 07:37 PM ---------- Previous post was at 07:31 PM ----------

I think I have good news, but I can't be sure. I just went on the Chinese forum and found this thread:

ttp://bbs.teclast.com/thread-257105-1-1.html

Seems like they solved the camera problem with an app that can be downloaded here:

ttp://pan.baidu.com/s/1mg7Ny7u

And there are some comments which say that it works, that you can turn the tablet all around 360 degrees and the image is the correct way up, but as I don't have this tablet (still hesitating and wondering whether to buy one...) , I can't test it out.

Do let me know if it solves the problem!
[Teclast X98 Air 3G] BoORDeL:
No it works inverted without BSOD :laugh:
[Teclast X98 Air 3G] keepfishes:
Hey guys, I found a very detailed review of the Teclast X98 Air 3G, much better and whole lot more detailed than the one posted on the first page. It's by the same person, all credits go to iambillbil for the wonderful work put into reviewing this tablet. I suggest the OP update or add this link to the first page. :)

The link is here (for those who can access it, for the teclast forum you have to sign up for an account and reply to the thread before you can view the hidden content...):

ttp://bbs.teclast.com/thread-253051-1-1.html

It talks about everything from speaker volume to eMMC speed to wifi/3g speed and benchmarks comparing the 3736F to many other tablets, definitely worth a read. :)
[Teclast X98 Air 3G] vgiozo:
Can anybody else provide any input on this?

I am ready to place my order (tomorrow) but there are some things that are putting me off

- Doubts about software support for Windows by Teclast

- Windows installation taking up too much space on the flash card, that perhaps leads to degraded read/write performance

- The fact that the official retailer of Teclast on Aliexpress is showning signs of opportunistic behaviour...specifically anticipating the Nov.11 deals it changed the warranty terms, shortening the period to just 6 months and treating all tablets bought at that sale as "promotion products" that don't get a refund; basically it is saying to its would be customers that by getting the tablet at a decreased price, they are getting a lower support deal...

- Other options/stores are quite expensive when it comes to the embedded Windows version of the tablet.

- I am kinda getting the feeling that Teclast is adapting its market tactics to providing new products at shorter intervals, potentially letting support for previous ones suffer.

I am thus considering of waiting to see if any new products are released by early next year and perhaps buying from somewhere that supports Paypal, which from 29/1/2015 onward will be extending its buyer protection to 180 days, to cover warranty issues.
[Teclast X98 Air 3G] LVL91:
I got sort of the same issue very rarely which seemed to occur only under heavy load, which is a problem on every windows computer unfortunately...

Sometimes I press the volume buttons and nothing happens, but I

never

had to reboot.
[Teclast X98 Air 3G] severall:
I think i fix this by disable option in device manager for GPIO Buttons Driver: Allow the computer to turn off this device to save power.
[Teclast X98 Air 3G] BoORDeL:
Nice review.

If i understand this tablet is a must buy.

am i wrong?
[Teclast X98 Air 3G] Maringer:
Well, my Teclast has just arrived. Shipment was a lot quicker than I originally anticipated so I'm really not quite prepared!

I was sort of hoping that the various software problems would have been ironed out by the time that I received my tablet but it seems I've got the most up-to-date release of Android (v1.10 dating back to late September) which, from reviews, I understand isn't particularly smooth in action. I'll have to root it when I get the chance and then see how well I get along with it.

In the longer term, I suppose I'll have to try out Windows 8.1 as reports have been good but it is just a bit of a pain that I'll need to spend some cash to purchase a license, not to mention gathering together all the necessary paraphernalia to successfully move from Android to Windows (I don't own a powered USB hub and may need to buy a couple of cheap USB sticks as well).

A couple of questions. The cheapest method of getting Win 8.1 Pro seems to be buying a download key. If I was to go this route, would I still be able to download the ISO to streamline in the necessary drivers?

I was originally hoping that I'd be able to get away with avoiding paying for Windows by installing the Win 8.1 Bing version, but if I've read things correctly, there is no license key with this beta version (because the screen size is over 8" in size?) and the reported trojan in the installation is a worry! Any other reports about the Bing version of Win 8.1?
[Teclast X98 Air 3G] mirek190:
I have a question .

Win 8.1 must be 32 bit or I can install 64 bit as well ?

Is it very important for me.
[Teclast X98 Air 3G] jacfry:
Thermal issue - significant improvement

I've just cut the blue thermal pad under shield lid into smaller pieces and put it on all ram chips (as suggested before in this thread). Then between the shield lid and the back cover I've put a copper strip covered with thermal paste. It caused some pressure on the circuit board so now the display and the back cover gets warmer around this place

The bottom line is that I can play Asphalt 8 under windows even when the "camera fix" is applied. Before I had to install the latest intel drivers to be able to finish at least one race without freeze.
[Teclast X98 Air 3G] supercowz:
1) is up to you for my sister tablet i choice 4GB since she dont use much android, for my tabet i choice 8Gb

2) yes flash bios, and flash android 4gb or 8gb then install win8.1 on free space left ...

all my latest file are on my youtube video ....

[Teclast X98 Air 3G] supercowz:
yep i agree ..

i did change the bios on Toolbox, i remove old one and add dualboot, since one guy brick his tablet by flashing wrong bios

but root the tablet with Toolbox is way more easy

like my friend SUMMERBREEZE say just right-clic and RUN root_me!.bat as admin !!

[Teclast X98 Air 3G] ambrosio5:
Hi,

Thanks for your post!

I've tried it on my C6J6 though and because the drive is ΝΟΤ digitally signed windows ignore it. Ans so GSensor only get removed but not properly added (except if you do a manual install, which of course is not the case in this solution).

Has anyone faced this?
[Teclast X98 Air 3G] Gall Anonim:
I've been slightly misunderstood :P

1) How much free space is left for user in Windows? In specs I've read that Windows takes 16 GB, so there will be only 2,5GB free if I will install 8GB Android? :/

2) I'm just curious what if I got dual bios tablet and then I change my mind and I want to install 8GB Android or reinstall Windows. Will be that problematic?

PS I've made a small donation (I hope this would be enough to buy coffee in France :P ) on your PayPal account, keep up the good work! :)
[Teclast X98 Air 3G] SUMMERBREEZE:
I have changed my tablets dpi setting to 264 ppi and i can play Dead Trigger still.. just it crashes some time later cos of gpu&cpu heat issue.

So please before changing DPI, download the games and install them, and later change the DPI setting..

Just be sure in app, width : 2048 Height : 1536 DPI :264dpi
[Teclast X98 Air 3G] supercowz:
1) 4gb leave 18.5 8gb leave 22.5 after win install if i remb well, should be 14gb or 10gb left

2) no big deal, no need to reflash the bios, just re-flash 8gb android then win8.1, very easy

ps : thank you very much !!! :)
[Teclast X98 Air 3G] SUMMERBREEZE:
so under the shield, on the chips(cpu,dram,emmmc etc) , you just put blue thermal pad as small pieces and close the shield?

And on the metal sheild of this SOC unit, you used thermal grease and put the copper strip and once more you used the thermal grease and close the backcover? i mean copper strip, covered by thermal grease from both sides? And do you remember and cann guess how much mm thick was the copper strip? aprox?

Thank you

[Teclast X98 Air 3G] supercowz:
oh yes .... and they are official dealer .... they dont know much abt what they sell, they just sell ...
[Teclast X98 Air 3G] jacfry:
Yes

EXACTLY

I just used two 0.1mm one over another, but I've put it on the original termal pad that's on the lid. Of course a single strip 0.3mm would be better. The top strip extended over the battery, but ther was more space so it doesn't fit tight (just a radiator :) ). I've also noticed, that between pcb board and the display there is some thermal tape, so I suppose the pressure made by the added strip might have pushed the pcb toward the display and made the proper contact.

My solution is very far from optimum, but even this works well :)

One more thing:

As we noticed that the dimensions of X98 Air are not as advertised probably is was designed for different case. Now we have to fill in the gaps with some heat conductor
[Teclast X98 Air 3G] Gall Anonim:
Bad news :/

I've managed to update BIOS, but I can't flash Android :/

[Teclast X98 Air 3G] SUMMERBREEZE:

Do you think, if i remove the original black(or dark brown) foil on the metal sheild of SOC unit and put directly THESE ONES for example 6 pcs with covered thermal grease, and close the backcover, would it fit OK? or too much?
