Boox T68 Plus

[downeaster59]

In case anyone is interested, Banggood.com now has the T68 Plus and a few other Onyx devices on sale. The main differences seem to be that the Plus has 8GB of internal storage and 1 GB of RAM. As far as I can tell, all other specs are the same as the "old" T68.

I've just bought one to replace the T68 that I sat on. I'll post a semi-review when it turns up.
Cheers, Warren

Wha is the difference between this an C67ML (beside the slightly larger screen size)?

The android version is even earlier.

[downeaster59]

I can't speak for the T68 Plus, but I had a T68 some time ago. It had a number of glitches and was fairly slow. The C67ML is quicker, has fewer glitches, and is compatible with more apps. The T68 really needs a faster CPU and some other hardware improvements. It has a good screen, but needs better hardware to support the screen. Perhaps the increase in RAM in the Plus will help here. We shall see.

Yes, I agree. The T68 works perfectly as ereader but is a bit on the slow side to work comfortably as a tablet. It works, if you really need it, but not always comfortably...

My T68+ just arrived from bangood.com along with a free cover (thanks!). So far I've rooted it with Cydia Impactor. Using adb, I can see these differences between my Lynx T68 and the T68+

                Old      New
Partitions
----------
/system        364M     364M    
/data          495M     495M    
/cache         247M     247M    
/mnt/sdcard    2G         5G      

Memory
------
MemTotal:      478996 kB  999180 kB

Both the Lynx T68 and the T68+ report an ARMv7 Processor rev 10 and a Freescale i.MX 6SoloLite EVK Board. However, the Lynx reports a BogoMIPS of 790.52 and the T68+ reports a BogoMIPS of 1988.29.

I can't do a performance comparison just yet because I've heavily modified the Lynx T68 (ADW Launcher, many other things). Once I get the new device set up I'll do a comparison.

I'm a bit annoyed that the T68+ has more flash storage but they have kept the same /system, /data and /cache partition sizes.

More soon, Warren

A bit more information. The Lynx build is 1.6.3 dated 2015-01-10. The T68+ build is 11-48_dev_944bbe7 dated 2015-07-24.

Screen brightness is a bit different. I'm using the Power widget to cycle between low/half/full brightness. The Lynx T68 low brightness is the same as the T68+ medium brightness, and Lynx full brightness is the same as the T68+ half brightness. In other words, the T68+ is dimmer than the Lynx screen.

[DoctorWkt]

OK, I've got the new device pretty much the way I want it, apart from fixing the splash screens. My T68+ is definitely much dimmer than the Lynx T68. The CPU doesn't feel any faster, but the screen refresh is faster: probably 2 or 3 fps instead of 1 fps on the Lynx T68.

Now and then, about 2-3 second after a session of scrolling, the screen will do a full refresh on its own. It's a bit annoying but I will probably get used to it.

The touch screen calibration on the T68+ is as good as the Lynx, perhaps a bit better. Still, about one in every 10 or 15 keystrokes is picked up incorrectly.

Overall: I like the faster screen refresh, it gives the device the feeling of faster response. I'd wish they had allocated more of the 5G flash to /system, /data and /cache. Having more RAM might help to speed things up but only if you have a lot of apps running.

Cheers, Warren

Can you confirm the processor in Plus is identical to the non-Plus version except the operating frequency?

BTW, a few photos to show the brightness difference will be appreciated.

Thx.

[DoctorWkt]

I'll try to do some photos or some video over the weekend to compare the two devices. I just ran Geekbench 3 on the T68 plus, here is the comparison against the Lynx T68:

• Lynx T68 results
• T68+ results

There is no real difference in CPU performance.

Some more comments on the two devices so far. The Lynx seems to give much better contrast, especially if you scroll a book page or web page. The T68+ doesn't seem to bring the e-ink particles back to their original darkness: when you scroll a page, it becomes lighter than before the scroll. And the time to do a full refresh (holding down the menu button) is about twice as long on the T68+ than on the Lynx. I'm guessing that this is a firmware change and not a display change.

Still, I prefer the T68+ as it is more responsive than the Lynx.

Cheers, Warren

According to me the Onyx T68 is a great device, but it has accuracy problems with the touchscreen and It is often very frustrating to use it :-(

[DoctorWkt]

I got up early and made a video comparison of the two devices.



If the embed doesn't work, here's the Youtube link.

Apologies for the ums and the hasty editing!

Cheers, Warren

I've noticed right now (banggood.com/) that the Onyx t68 Plus has an infrared touch screen. Instead the Onyx t68 has a capacitity touch screen. Is it correct? I haven't seen in DoctorWkt's video how Onyx T68 Plus works about undertiling words and sentences on Alreader or Neo Reader, but using a different technology Onyx T68 Plus should work properly about clicking, selecting things and underlining, right? I was thinking to buy the Onyx i86 only for resolving the accuracy problems of the touch screen on my Onyx T68, even if the Onyx i86 has a screen too big for me, but if the touch screen works properly on the Onyx T68 Plus I could think to upgrade with it. What are your thoughts about it?

I think the problem are the last firmwares: they refresh the pages too often and don't bring back the pages to the original darkness, that's why I've on my device the Booxtor firmware (20141014): it works much better than the last ones. I was thinking to install on my device the last firmware (only because there're some improvements about Neo Reader) and after using this app to correct the refresh mode > https://www.youtube.com/watch?v=ElVF6FgBx3Y

Unfortunally Piotr4 has not yet published the App on Google Store.

Have I said something wrong? No answers :-(
