Boyues Likebook Mars T80D: malfunctions

[PUIB5376]

Hello,
For several months I have been experiencing malfunctions with my Boyues Likebook Mars T80D.
After reading a few pages of a book, the screen begins to flicker and, depending on the case, the screen freezes on the current page or the font size decreases and the pages begin to scroll at full speed mostly backwards. If you close the support flap (standby) and reopen it (exit standby mode), the eReader sometimes starts to work correctly for a few minutes before the fault reappears.
This type of defect is present whether it is with the Boyues reader or one of the Koreader or Moon+ Reader applications.
Under these conditions, my Mars reader is unusable. I tried several times to restart the system but without success.
I also performed a factory reset twice but these malfunctions persist.
I'm currently on Android 8.1.0 and just updated to V3.1.1, but I'm having the same malfunctions as when I was on V3.1.0.
Can you provide me with your technical support because I no longer know what to do to resolve these malfunctions?

Hi there,
I still have the same malfunctions. I don't know what to do... Are there any users of the Likebook Mars reader for whom reading epub books works correctly or do you also experience malfunctions?

I have no problems

Hi. I own a Likebook Mars reader for almost two years now and I don't have the problem reported by PUIB5376. My reader is updated. I mainly use the Boyues reader included, but I also have KOReader, but no problem at all.

Did you try to remove the device from cover?

Hello again.
I have checked my eReader and there is a pinhole on the bottom near the micro-usb connector. I've never used it but it's worth a try in your case, with an unusable device. Try resetting your Mars and don't forget to report back if it worked. Good luck !

This pinhole is the upgrade key

No, I didn't think to remove the reading light from the lid. I'll give it a try and let you know the outcome.

I have used this procedure several times before to perform factory resets but the fault always returns after a few hours of reading.

Thank you for this info. If you don't have a problem with your reader, it shouldn't be a software problem, but rather a hardware problem???

Maybe ask in the onyx subforum. They might know what it is. You might be able to fix it. It sounds like a hardware fault.

That makes it sound like an issue with the digitizer, if you take the device out of the included magnet case then open a book or app that has lots of touch control surfaces then hold the device from the top and bottom and flex it slightly does the book or screen go nuts?

Also are you using a Micro SD Card or just the internal storage for your books?
