Hi. I have the tablet about 1,5 years. A week ago, it turned off and i couldnt charge it or turn it on. After 2 days, it decided to turn on but after that, the wifi is not working. It can “see” a wifi network “direct-b3-hp deskjet 3830 series” but it can’t see my wifi, or any other wifi. Even if i put it next to my router. i did a factory data reset but nothing happened. I tried to make it dual boot but i can’t find the icon of the ifwi app. In settings/apps i can see that this app exist but the icon to open the app is gone. Can someone tell me what can i do to fix the problem? thanks
