SAMSUNG Galaxy Watch4 Classic Bluetooth (4.6cm) Smartwatch

LTE esim activation on jio took its time.\nBut it is working.\nEsim activation is like magic.\nI purchased galaxy watch 4 classic LTE version 46 mm 4.6cm\nDaily driver OnePlus 7 pro. (Watch 4 Esim activation successful from OnePlus device)

Superb watch, with bad battery backup Then again I use it with wifi and lte so that contributes to bad battery backup. Excellent sync with apps from Play Store and works so well wit the wearable app on my samsung phone. It’s like having a second phone that I need to charge each day. There are ways to get the battery backup to 2 days and even more if you keep it on grescale mode with aod switched off. Like the water resistance which works really well. Another good thing that it is future proof, to an extent, with its 5Ghz Wifi connect, Play Store and LTE. The only reason I would upgrade my watch if the newer version comes up with solar charging capability and 5G instead of LTE.

It’s my dream It’s very good product

The looks are brilliant.. design is very good.\nAll plus for the appearance and the way it looks on your wrist.\n\nExercise tracking is good..not much error seen. It is almost accurate.. a miss here and there.\n\nSleep tracking: it does catch on the sleep patterns well.( the wake up and sleep times)..but not sure how accurate it is on the patterns. \n\nThe actual let down is on the health tracking.\n\nSpo2 -.the values are a big let down. . The measurements values are in a wide range… .I used a medical grade spo2 meter and this.. the values on the watch was in the range of 89 to 100… . The values on the spo2 meter was in the range of 96 to 99.. that is a big difference and a big disappointment. \nThe spo2 measurements while sleeping is not reliable as well.\n\nBlood pressure – we cannot use this option on the india version which is another big let down…. but a simple tweak can make it work.. I had tried to test this.\nThe first thing is we need a physical digital blood pressure monitor to calibrate the watch .. this calibration has to be done every 1 months on so… what kind of stupid thing is this.\nNow after calibration. The values obtained on the watch has variation on the ones obtained on the physical meter.\nA difference of 8 to 10 points here and there.\n\nECG- tested the ecg feature and it showed me sinus rhythm.. not sure about the correctness of the measurements.\n\nThe end summary is that.. why does samsung charge 36000 plus for a watch which has so many issues . \nThe watch is bought for it’s health tracking capabilities.. and if the measurements are so erratic.. what’s the use of paying so much money.\n\nI have seen watches with spo2 function costing 9k to 12 k do the same thing and give the same results.\nWhy are we paying so much for this stuff.\nIt’s a big let down. And a big disappointment from samsung.

The watch is solidly built, and the fitness tracking is spot-on. Sleep tracking is also quite accurate, and the only issue I have is with the BIA sensor which gives wildly fluctuating values for BMI and body composition. Aside from that, the watch is a solid piece of investment. Battery life maybe considered poor by a lot of people, but for the features the watch provides, 24 hours isn’t that bad. I do wish the charging was faster, but oh well. Coming from an ageing Gear S3 frontier that serves me well for more than 3 years, I’d say that the Watch4 is miles ahead. Happy with the purchase.
