Hello,
I received my Teclast T8 last week. One of the first things that I did was to update the firmware via OTA and after the upgrade I noticed that I miss some functions that I’d like to have in my tablet.
That’s why I tried to install any other launcher, but if I try to install it from google play store I always get Error -501 (even following the instructions found in several pages about clearing cache/data).
I’ve tried to download the apk directly from the web and/or from apkmirror and when I install it the message is always the same: Install the app? Yes–> Application not installed. The same error happens, I’ve tried like 10 different launchers and there’s no way.
I tried to install those launchers via Aptoide too but the result is the same “the application was not installed” message.
Do I need to root my device or do I need to change any specific configuration? (I already have activated the “unkown origin software” option in settings/security)
Any help would be appreciated. Thank you.
