[Android Q&A, Help & Troubleshooting] italianquadcore:
"double tap to wake" feature is not necessary because we have the fingerprint sensor that does the same job.

To enable fingerprint function, we have to do:

1) Go to "Settings -> Fingerprint"

2) Select one mandatory item : Pattern, PIN or Password (it will be used for unlock device without using the fingerprint sensor)

3) Follow the instructions to set options for above-mentioned selected unlock item.

4) Now you see the "Fingerprint" window. Tap on "Add fingerprint" and follow the instructions to add a fingerprint.

5) Now you are again in "Fingerprint" window, but you should see the new item "Finger 1". Eventually we can add other fingerprints using "Add fingerprint" button.

6) Now you can read all options inside "Fingerprint" window. Options mean:

a) "Unlock screen". To test it, poweroff the display. Put your finger on fingerprint sensor and display will be powered on again (so it can replace "double tap to wake" function).

b) "Access app lock" works with Teclast app whose icon shows a lock (name of this app is displayed in chinese language). Inside this Teclast app, you can lock some apps (use the slide button on right side for each app) - if you run these apps, you must unlock them using fingerprint (or eventually use the Teclast app's pattern). Note : Teclast app's pattern has nothing to do with Android screen lock's pattern.

c) "Take photo/video". Open your photocamera app and use your fingerprint to shoot a photo or to start recording a video.

d) "Long press fingeprint back to the main interface". Use it to come back to home/desktop. Same feature of Android's "home" button.

e) "Double-click on the fingerprint out tasks recently". Double tapping on fingerprint is used to open the task manager, another double tapping on fingerprint is used to open the most recent opened app (this feature works even without using fingerprint).

Unfortunately if you enable fingerprint, you must enable also the screen lock feature. If you go to Settings -> Security -> Screen lock, and try to select "None" or "Swipe", Android will ask you to choose to cancel (so you keep the fingerprint feature and also the current screen lock) or to remove your saved fingerprints and disable the fingerprint feature in order to let use the selected Screen lock. There is no way to avoid this. So if I want to power on the display using only the power button without using any screen lock, I have to disable the fingerprint.

Yesterday, before reverting to firmware v1.28, I've tested the firmware v1.03, it seems to be the same (more or less) as the v1.28, but it arrives directly in english language, there is no evidence of chinese apps and/or icons, the only chinese app remained is the Teclast's TeclastOTA app. I just tested it for about 5 minutes, so I have no other opinion about this firmware. In 5 minutes I've no faced any problem with touchscreen, no ghost touch, so theoretically v1.03 should be similar to v1.28, at least regarding the touch screen software. Anyway we have to consider that if we'd like to pass to firmware for E3C5_G device, in the future we may have problems to get full .zip firmware file for the upgrades, we have only full .zip for v1.03 and OTA .zip files for the future upgrades - at least NeedROM site provides all series of full .zip firmware files for E3C5 device.

I attach 3 screenshots for your reference.

As per answer of ET moderator (just see his answer here), it will not be so simple to have a forum dedicated to tablet Teclast Master T10 here on XDA. As far as I can understand about XDA policy, we need to have at least a certain number of threads discussing about this device, but also a good number of people/users discussing about it.

So I suggest to create other 2 threads for this device, one dedicated to the accessories (micro sd cards, covers, glass screen protectors, cables, etc...) and one dedicated to all other discussions except root (we can keep this thread for discussions about root - considering also that, currently, there are no customs roms around).

Waiting for your opinion about this proposal.
