Redmi
As you know, Redmi is India's best selling smartphone but user have reported that Redmi has got issues with photos it captures, yes usually the images captured from redmi smartphone has got over saturation.
One of the worst issues with Redmi smartphone is it's UI, the User Interface of Redmi has got so many issues, the phone lags a lot worsening the user experience. Moreover Redmi has so many Ads and notifications which is really annoying. Users have also reported that Redmi Smartphones heats up quickly while used for a longer duration. Finally talking about user security just forget it.
Poco
Poco has got so many fans out there due to its unique style, UI and performance but unfortunately after the Poco X2 became a hit in the market, poco lost its value. Since the time Poco became an independent brand the phones they launch are just rebranded smartphones and there is nothing unique or new in the smartphones they recently launched after it became an independent brand. A independent brand is something that launches its own unique products so poco is just producing rebranded smartphones disappointing its Fans, so let us hope for something new in future from Poco.
Vivo
Vivo smartphones that come under 20k are not smartphones they are just trash, yes Vivo just focus on its Camera and design and its a real trash when it comes to performance. The Vivo smartphones that lie under the pricing of 20k have poor performance when compared with other phones. Users have also reported that Vivo does not update its software, there has been complains stating Vivo doesn't release any update for a span of 1 year or a span of 6 months. The security patch updates are also not something that is to be appreciated.
Samsung
Samsung usually focus on Camera, Display and battery, the recently launched "M" series smartphones i.e m21,m31,m51 have been giving heavy competition to its rivals. It is also said that Samsung m21 is the most sold out phone of 2020 on Amazon, but Samsung flops when it comes to performance though the pricing and the other specs are really great the performance of the phone is still an issue. Suppose if Samsung overcomes this issue too then it is truly evident that Samsung will become the top brand Smartphone.
Micromax
Well, Micromax is an Indian brand and the company was famous during 2014 and 2015 with its "Micromax Canvas" model but suddenly disappeared after a few years and now on 2020 they made a comeback with low price range and great specs model since the governments "Atmanirbhar" idea rolled out. It is a great comeback for Micromax but they compromised a lot in terms of Built-quality of the smartphone.
Many users have reported about the quality check of micromax smartphones and taken it to the social media and criticized the phone, there are problems with back cover and many users faced problem like phone coming out of the frame and the phone not properly aligned.
Oppo
Oppo has always been a boom in the offline smartphone market, and Oppo focus just on its design, the camera especially and comes with styling features like "Slim Phone" and yes it is an Innovative phone as well. Oppo is well known for its photogenic capabilities but then all the Oppo smartphones that comes under the price range of 20k have poor performance, that is Oppo is not suitable for high performance activities. Gaming in Oppo phones are highly not recommended. If you are a photogenic then yes you should go for this one.
Oneplus
Oneplus is everyone's favourite android phone and yes its the best smartphone ever and was also known as the flagship killer, but now not anymore a killer its just a flagship phone as Oneplus is losing its brand value. There was a time when a Oneplus Smartphone was priced at 35k - 50k and now they are trying to enter the budget phone segments and losing its fame. The low pricing of Oneplus can make it lose its Brand value and brand image as well.
Realme
Realme is indeed a great smartphone and is been in heavy competition along with Redmi. Most of the Redmi users are switching to Realme as it has everything placed at its best be it processor, performance, battery, display or camera. The only fault that Realme makes is they launch too many smartphones with the same price, same design, same features, same specs but with a different name confusing the customer. Another Issue with Realme phone is its camera, the images captured from a realme phone usually has color defects like over boosted colors on the images the camera of Realme Smartphone captures
