Three smartphones that failed before their arrival

 Let me tell you three such smartphones which failed a lot.

 1. RED SMARPHONE - Nowadays smartphones have very powerful cameras but there was a company which used to make picture cameras like Marvel's Spider-Man, Iron Man, they used to make such pictures, this was Red's camera, they also made their own smartphone but its theme is normal, pictures are normal and price is normal, the camera in it was also very powerful but because its theme launcher and all the pictures were old, customers said bye-bye to it 

2. samsung note series - Samsung's Note series is the most selling series, you must be aware of it, but Samsung's Galaxy Note 7 was a bit too big, sometimes the phone would also break, but the company replaced it and made it better, and due to a small fault in this phone, the battery also had a lot of problems and sometimes it also burst, but Samsung replaced all the old units in it, and its next edition turned out to be very sturdy and lasted for a long time too.

3. Amazon Fire Phone - Amazon started selling books and was successful in it to a great extent. Then Amazon also spent 200 million rupees on its phone. The Fire phone was a very good phone and had very good pictures but the only problem with it was that due to its high price, customers never bought it from it.
