Have you recently had the display replaced? When did this issue pop up? Did you buy it second hand and has it always been like that. There's no real way to fix a broken touch ID sensor. It's more likely that the home button was replaced with a different sensor making it unable to be used woth touch ID since it's not the original sensor If you got it like that and it wasnt noted id file for a parshal or full refund (if you're willing to return the phone) If this happened after the display was replaced it means the repair shop or you who did it has put in a new home button that won't towkr with touch ID since it's not the original one that came with the iPhone. If it just randomly stopped working it could be a software issue but it's most likely a hardware issue and I'd suggest getting the home button repaired by apple or a 3rd party if they can. Hope this helps
If you still have this issue just look up factory data reset for you Blu vivo go. Search that up and foow the instructions and it will reset your phone to factory settings. It will be like a new phone again. You'll lose all of your data but you won't have a passcode
You've most likely rubbed off the gold or maybe they fell out naturally? Usuay when they won't change back colors it means that they're not even there anymore. At this point you should just replace the entire display.
Do you have a screen protector on the phone? If you do it could possibly just be a case of a bad cheap screen protector. If not it could be an actual issue with the buttons themselves. Or it could just be phone lag if they eventually do respond or if the phone freezes when you press them. Hope this
The only real solution in this case is to either find a way to get the other cable to work. Replace the entire screen to get it to work again. Swap motherboards with another phone since these phones can be found sub $50. Or if you have a PC that you've previously trusted on the phone you can connect it to that pc and just move the data off of it.
I'd recommend just replacing the entire screen. Most likely you'd break the screen anyways when replacing the glass as that part on a screen isn't exactly designed to be removed. An entire screen replacement is pretty much necessary unless you're a professional phone fixer.
One of the connectors could've been unplugged and you haven't realized it. Or you could've damaged the connector when opening the Apple watch. I'd suggest opening it up again and making sure that all the screen cables are plugged
I've had this issue with other phones. Try and use a different WiFi network or just simply keep trying on that one. It's a software glitch but if it can connect to the wifi it should be fine. Just keep
