Hi and Welcome. My Name is ***** ***** I look forward to assisting you today with your question.
Sounds you turned on Accessibility setting TalkBack. What is the model and make of your phone ?
What is it showing now ? Is it stuck at welcome screen ?
Since you tried to reset it factory settings, you can do it again using the following method.
Turn off the phone
Press and hold down Volume Up + Home + Power buttons at the same time for a few seconds.
Android system recovery will be loaded now
Select wipe data/factory reset. (Volume buttons to go up or down, select with Power button)
Select Yes — delete all user data.
Then select reboot system now
That should factory reset the phone. Let me know how it goes
How is it going ?
