Oppo - Don t produce Oppo A 59 phones

Here's my experience for using this phone for * year and * months:

When submitting a file/ pdf/ doc to my university's official website (for assignment purpose, you know what happens? Let me tell you.
First,
It redirects you to Google drive and lets you select that particular file I want to choose BUT, OPENING THE DRIVE ITSELF TAKES LIKE...WHY...
Second,
After going all this disaster, the most SERIOUSLY FRUSTRATING PART...
AFTER CHOOSING ME DESIRED FILE FROM DRIVE...THE APP, CHROME SAYS WHAT YOU KNOW..?
"The previous action couldn't be taken because of 'low memory'" or 'low RAM'.

And after this the whole loop starts.
Again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again repeating the same thing like I've even lost my reason why I was doing this and by the time I wanted to do it one last time, our university has this time limit to submit our assignment(s). If not then the 'submit' button won't let you.

Guess what happened.
Yeah my ASSIGNMENT WAS NOT SUBMITTED AND THANKS TO THIS PHONE (my god...)

I seriously
Hate this
Phone.

I regret buying it THAT TOO ON MY BIRTHDAY.

(I would really use forbidden words but I have my common sense. So please. DON'T PRODUCE LIKE THESE SIMILAR PRODUCTS AND I KNOW THAT I DON'T HAVE RIGHTS TO SAY BUT I'M DONE. I'M DONE WITH THIS PHONE.)
