Oppo phones

I've no idea what an Oppo phone is but if you Google 'Oppo phone' you will find your answers. It says:
Oppo phones have mediocre phone specs compared to its price. With the same money, you can buy a higher specs phone, or save significant money if you buy the same specs phone from another company. Oppo frequently uses an outdated MediaTek processor. MediaTek processors are known for poor quality.

I bought an Oppo last year because they were value for money. Had no problems with it at all. I don't see the point of paying more for something that does the same thing but I'm no tech expert.

I have an oppo phone , love, it no problems whatsoever . My opo does everything I want it too. No regrets on my purchase.

My husband has an Oppo and finds it really good for everything. Excellent value for money.

Typing this on a Oppo phone. Absolutely no problem with a good camera, almost identical spec to similar Samsung, which I originally planned to buy. Really like this phone.

They’re no use to me, I don’t have the manual dexterity or vision to get much use out of smartphones, my iPad mini has all the features I need and my faithful old Nokia for emergency calls.

^A 2012 U.S. congressional report labelled Huawei a national-security threat, saying its equipment could allow China to spy or disable telecommunications networks. Smaller U.S. carriers use Huawei gear, but the report made it politically difficult for bigger ones, such as AT&T Inc., to do so.
