Anonymous, 10 Apr 2021interestingly cpu-z shows that it has a whole bunch of sensors like gyros and accelerometers, ... moreThe gyroscope is not real, it's a virtual device, the data comes from aggregating real accelerometer sensor and real magnetic field sensor, via "sensor fusion", Kalman filter. It was saved for budget. Real gyroscope provides a reading within milliseconds, but sensor fusion has a delay of at least a hundred milliseconds, usually more. So it's not at all useful to provide image stabilisation and any such features.

The only instantaneous reading is from accelerometer alone, but from that you can not determine whether and how much the phone was shifted laterally (no compensation needed for infinite focus distance) or rotated (compensation needed). For nearby focus distance, the compensation required for these two different movements is both needed, but it runs in the opposite directions for the same accelerometer input, but it's also not usually implemented, since infinite-focus assumption can provide an overall less confusing result.

                              So as a long term user of Samsung, I finally switched to Xiaomi about 3 months ago and I must say this phone is awesome! I bought the 3gb variant even that performs really well.. I have over 20 different apps and games installed and non of them lag.. and for those who complain that the phone lags, maybe close the 100 other apps you have running in the background..cos even a super computer will lag if you push it hard enough. Anyways..back to my review.. yeah..the phone is awesome.. I played cod and pubg and those play flawlessly too without any lag or over heating even when I use my phones data rather than wifi.. and finally the battery life is just amazing.. can easily get through a day with continues usage.. like for an hour of youtube with phone data on, about 7 to 8% battery tends to drop.. so, do the math and you will see how good the battery is.. if I have one complain though, that is the phones OS takes up lots of space so I regret buying the 3gb version cos it only comes with 32gb internal storage and only 20gb or so is usable.. So in conclusion..the phone is awesome and even the 3gb ram variant runs flawlessly but if you want to have a lotta of games and apps installed, go for the 4gb 64 gb variant of higher.

                              Also, to anyone having issues with the proximity sensor.. if you have a tempered glass with a black boarder around it, remove it right away cos it will mess with the proximity sensor.. I had one installed when I bought the phone itself and it completely stopped the sensor from working.. but as soon as I noticed the black boarder, I took it off and now it works fine..

                                Redmi 9 is so slow, the 3/32 variant is so slow. Don't buy that one because the system eats up 2 gb of ram and you have 1 gb left, why do I think so? It,s in the app used button in the below of the screen that says 1 gb of 3 gb. It lags, the camera is so dumb, the system rom is also dumb, eats up 11 gb of your space.
