Sorry to hijack an A3000 sub-forum with what appears to be an issue on A3500/A5500 Lenovo tablets, but seeing that there is no other place to post this I decided to go ahead and do so here. If the admins chose so, please move to a more relevant sub-thread. Please bear with me as I describe the issue below...

So I bought this A5500 the other day and was immediately confronted with what -as found at a later stage- appears to be a widespread issue on Lenovo's A3500/A5500 tablets. The issue is quite easy to replicate and is clearly evident when scrolling through a page with the finger in direct and constant touch to the screen. In this case the flow is jumpy and non-continuous as shown in the video below.

Link inserted here, however since I'm a new member I'm not allowed to attach as an external link, hopefully pasting as text link is allowed, however functionality is obviously hindered somewhat...Sorry about that, nothing I can do on my front. Please remove respective spaces from the link below to view the video, thanks.

What strikes me most is that I couldn't find any mention of the issue anywhere on the internet, seeing that it has obvious knock-on effects even on sketching a simple vertical line as shown above. So this happens only on the vertical axis, on almost all of the Lenovo A3500/A5500 devices I could get my hands on, even on the display / demo units found on major retail stores in the vicinity of where I live (South Europe). And I say almost, since apparently A7500s (A10s - 10'') models DON'T exhibit said behavior, which is ALSO the case with most other branded tablets I managed to test, either LG, Asus etc...

So my question would be if this is a known-issue for these devices, or something's gone horribly wrong with the digitizer panel of specific batches of these and need to be replaced by the manufacturer...In either case if you happen to be the owner of one such tablet, please take some time to perform these tests and report back.

Thanks!
