It was 6 pm Gmt +7 when my phone started acting like a bitch by re-starting every one minute. At the same time, A friend bombarded me with a call and didn't care I was actually in the middle of a panic situation. I kept rejecting her calls and I was triple annoyed. I tried to uninstall a recent installed application eSteem and thought that would solve the problem but nothing was happening.
My Phone is Samsung Galaxy A3 2016 which runs on Android Lollipop before I updated the system to Nougat. It was a week ago that everything runs smoothly. I personally doesn't like nougat interface and its annoying notification about "apps that drains your battery" and a whole lot of things. in short, I like lollipop better.
So, my first diagnosed was it's caused by my phone's battery but it is most unlikely because I just have this phone for about 5 months. Lucky, My housemate was home and I knocked her door to ask for a tethering so I could browse on google and see what's up.
Simultaneously, I was logged in to discord, asking people around from 
Re-boot and Reset
In a very panicking situation, suddenly I was having a brain shut down. Nothing works. Just panic attack. Fast forward, I performed a hard reset. At this point, I thought I could use my phone straightly again but heck no !
Turned out there's a thing so called google verification and there's no way I can ever use my phone without inserting a google account
At this point, I tried to insert my primary google account but there's a problem, I forgot my password 😆 . I have tons of password and I keep switching them often until I forgot which is which. I did a reset password but again It told me something like :
Unable to login due recent password change, try again after 24 hours
I was more annoyed and tried to look for a way to bypass the google verification. I tried some tips I got from forums and voila ! . None of them worked. Then, comes a point where I thought " Okay let's just wait" Yet another side of me insisted to keep on trying. I previously inserted my other gmail account and none of them worked. Until, I tried to insert my least used google account and voila it worked!
So, if you don't want to go through the same situation like I was.Disable google verification beforehand. It will save you time and unnecessary panic attack.
another note : In my personal opinion, I get the sentiment that google wants to know whatever apps I was downloading and whatever information I was browsing. Then, they would give me a relevant adds on youtube or article in my google feeds. That's kind of creepy knowing that " Big Brother" is actually happening. So, My advice for noobs would be " don't put your real credentials". Nice job google ! Try to spy me ! I am just going to use DDG :) from now on and won't use my phone to browse anything ever again.
Cheers and Have a great day everyone !
