I operate my Galaxy Tab Active3 SM-T575 almost exclusively in "no battery mode", i.e. battery removed and power supply via the supplied power adapter. Ran flawlessly with no problems.
A few days ago I installed the last software update (Android 12, One-UI 4.1). Since then there have only been problems.
When I open an app or switch from one app to another when Wi-Fi is on, the following happens:
- the WiFi turns off and then on again after a few seconds or
- the WiFi turns off and stays off; must then be switched on again manually or
- the tablet crashes and reboots again (in most cases).
Unfortunately, this is not a condition in which proper work is possible.
I have already reset to factory settings and also deleted the cache partition in the recovery menu. Without success!
I can definitely understand your concern here. Let's try to alleviate some of the stress by trying this link: https://www.samsung.com/us/support/troubleshooting/TSG01001559/ If this does not help I recommend letting a service technician have a look. As we would like to gather additional information and look at this from a case by case basis please provide the full model code and serial number of the device as well as your best contact phone number, name, and email.
