Questions people ask
What model number is the A3?
A real OPPO A3 reports A402OP or CPH1837 or CPH2639 or CPH2641. In Chrome, Phone Checker reads it from the phone itself, so a copy can't hide behind Settings.
How much RAM does the A3 have?
At least 4 GB in the smallest version sold. A copy often has less, whatever its Settings say.
Which Android versions does the A3 run?
It came with Android 14. A version older than 14 means a different phone.
How do I know if my A3 is original?
Open ogphonechecker.com on the phone itself and tap Check this phone. In about 20 seconds it compares the model code, graphics chip, RAM and screen with a real A3, for free.
