[Teclast X98 Air 3G] abanglek:
x98 air 3g dual-boot

32GB c9j8

64GB c9j6

aliexpress qkqi shop, as suggested by teclast

but any model doesnt really matter, because any model have their own issues. for example, i have c9j8 & the battery is not great, 4-5 hours no matter android/windows, & the charging time also need the same period, so charging & discharging ratio is not great. wifi is okay, but sometime it's just lost connection, even i have to disable & re-enable the hardware to get the connection back.

now i'm flashing c6j7 windows only bios & the battery is great, but i've lost 3g modem, but for now it's okay because i'm not using 3g data connection (i might be skipping 3g driver install) now i think i hope i just get the original c6j7 version (maybe c9j8 shared same hardware as c6j7), maybe the version still there for windows single os.

android os i think is redundant, redundant to the windows os, & redundant to my phone. i'm using windows phone, so not many apps or games as android, but it still redundant.

in my opinion for the future buyer considerations:

windows os

1) the screen is too small to windows os, i've rescale to 220% to acceptable zoom size, & rescale on-screen keyboard to be smaller.

2) touch only (no keyboard & mouse/touchpad) on windows is frustating & pain.

3) seriously, windows is home to traditional laptop form factor. i just hope i can get as slim & as light as it can with as big screen for windows system (in my dream >15" wide screen, <1kg/3lbs, <1" thin, >10hours battery, cpu&gpu doesnt matter as long as the system is smooth), before this (& still have it), i'm using dell v130 with intel ulv cpu, but the battery just dead, make it unusable to mobile.

android os

1) the screen is too big & too weight for the android. i have android tablet use by my kids, it's 7" 16:10 1280x800 & i think it's great. i've try my colleague 8" tab & i think i don't want it, i also try 16:9 ratio android & i don't like it. 4:3 ratio is great for reading but maybe have some issues to some apps. nexus 7 is great seriously, except for no expansion.

2) seriously, they are not optimizing the android, lag (eg: click sound is heard only after few word typed) & bad battery life is obvious. also skip screen. also low speaker volume. also low screen brightness. (vs windows on same hw)

3) they maybe fix update some issues but android version update is just in your dream, they simply leave it when new model is in production.

4) x86 cpu is not home to android, worsen by intel gpu. lot apps is working but some still incompatible, some are not optimized. simply get arm system for the android, P series for teclast maybe. the only know how to optimized x86 android system is asus, maybe new nokia n1 is okay, but still expect some incompatibility.

common (hardware) issues either on both os

1) build is not precise, you know it's a cheap production product even the material is premium. mine have some creak.

2) double glare on screen, make it unusable outdoor. 1st glare is on surface glass, it's dim, little spread & brownish, not an issues BUT the 2nd glare are on lcd screen panel, seriously it's just like a mirror, it's just reflex whatever the light source, even glare on your face, & you can do nothing without hardware hacks because it's inside.

3) wifi i can say is not great, it's just like my past (4-5 years) smartphone.

4) battery life is not great for dual boot

5) seriously i'm now skeptical about only 1 port for otg & charging, i believe just matter of time the the port will dead. my micro usb cable dead only after few weeks. now i can understand why ms surface or nokia 2520 using dedicated charging port, it's fast (vs micro usb) & it's dedicated, leaving other usb port usable, also the port will live longer (esp ms surface magnetic port).

in past, i think dell, asus or even acer are low end product, but now with vs chinese product, i can say they are new premium. i think i will keep this tablet because i love to tinkering my stuff, but i belive this tablet simply not for everyone.
