    What reviews almost never tell us - some personal experiences with Android phones in the last few months

    Posted: 01 Sep 2019 07:28 AM PDT

    About 7 months ago I posted this story about how not all BLE5 phones are equal and from the feedback I found that a very inexpensive phone did have the BLE5 long-range feature that I was interested in testing (for work) - so I got one. Later we needed to also test on a different BLE stack so I also got one S10e but in the end while I loved the small size of the S10e I could not stand the lack of notification LED so (after it became clear that the Note10 will also miss the notification LED) I ended up for my personal use with a deeply discounted Note9 (no long-range BLE5 unfortunately).

    And by comparing those (and a few other at times) side-by-side I also did notice that not all phones have the same radio signal quality - both for the cellular signal but also for WiFi and Bluetooth (I will leave the BLE part out of it for the moment for reasons related to my work).

    I will first repeat some points that I have written before in a comment related to the same topic (cellular radio signal strength):

    • the number of bars means NOTHING

    • what you want to compare is measured signal strength (with real numbers) - which is still of more types - see here for instance; also here where you get info on measurements in ASU

    • all Android phones show some signal strength number under About phone -> Status -> SIM card status; even that one might be confusing since some brands report RSSI numbers and other seem to show RSRP

    • on iPhone apparently you can dial * 3001 # 12345 # * (no spaces) but measurements will not come instantly and you need to know where to look

    • on most phones measurement values will change A LOT, and sometimes very quick

    • on Android I like a lot (at least for the moment) Cellmapper.net program

    • IMHO at first you should only compare values "side-by-side", ideally first with very similar phones and using same type of measurements; initially you MUST be on the exact same carrier in the same type of cellular network (2G, 3G, 4G - you can force those "down" from the default 4G/3G/2G mode) and on the exact same cell; in almost all tests I have made in 3G mode the signal is better (sometimes MUCH better, like 20 dBm better = 100+ times stronger!) than in 4G in most phones.

    As a general result from those tests PocoF1 comes out as excellent antennas/radios with the Note9 (Exynos) very close to it (and more efficient in some regards, and with a lot more bands) while S10e Exynos only comes the very last pretty far behind the other two (I would say on average around 6 dBm worse, which is 4 times worse = a LOT)! Numbers might still be misleading and different from one manufacturer to another or even from one phone to another but the above was double-checked in very bad conditions where the PocoF1 or Note9 were able to hold a connection and the S10e was not. Also from what I could see a lot of people are complaining on the web about the S10 cellular signal quality (including a huge lot on the Snapdragon version) so this issue does not seem to be just an accident.

    A somehow similar situation is happening on WiFi but with a small twist - when the signal is VERY good the S10e is clearly the fastest especially when on one of the new AX routers (since it has the WiFi6 feature), however when the signal becomes rather weak (and noisy) S10e is again falling behind - here below are some tests that I posted in a comment somewhere else.

    Tests were repeated 10 times at least (15-20 on the S10e) from about 6m/20ft and 15m/50ft on 4 phones = iPhone 8+, PocoF1, Note9, S10e. Tests seem to depend a little even on how you grip the phones the moment you are testing and of course can vary a lot depending on obstacles, reflections and other active radio noise (the "near" location is in one direction inside with just a few walls but no major noise, the other is opposite direction outside with a lot of metal reflections and close to some other radio-noise sources).

    All results are given like a range since variations were rather big.

    6m/20ft (speed range in Mbps)
    i8+ 300-350
    N9 350-450
    F1 400-450
    S10e 450-500
    15m/50ft (speed range in Mbps)
    i8+ 30-100 (*)
    N9 180-210 (**)
    F1 150-175
    S10e 90-120 (***)

    Notes:

    (*) the iPhone 8+ had extreme variability and generally very bad results at the far spot, also last from the near spot

    (**) Note9 was IMHO both the fastest and the most consistent at the far spot, probably better antennas in the large body!

    (***) S10e has seen a large drop (and on that one I made most tests since I wanted to be certain it was not some fluke). IMHO this also confirms the many reports on bad radio antennas in the S10e (this was also the most sensitive to the grip position).

    I will end all this long story with some of my personal observations/preferences regarding the 3 Android phones discussed (again some of them not really discussed in enough detail by most reviewers):

    • the PocoF1 has the absolute fastest fingerprints sensor, Note9 is far behind and the S10e even more so (and in-display ultrasonic even worse)

    • the PocoF1 also has instant face recognition (with 2D IR camera) that also works in the dark and is regarded as rather difficult to trick (not quite as hard as the 3D IR scanners from the iPhone, but that is in a wildly different cost class, and there IS a Mi8 model with that one too if you really want 3D IR face recognition)

    • on Pie all 3 phones had to be extensively configured to let certain programs still work in the background and not be closed but MIUI (the Android skin from Xiaomi) was IMHO somehow the easiest to configure and also the only one that keeps the items in the task list really locked

    • unfortunately Xiaomi is very bad with security updates - currently about 2-3 months behind and some models in the past were up to 6 months or practically abandoned; both the S10e and Note9 (both Exynos) were updated in the first 2 weeks of August to the August security patch even if the QualPwn vulnerability primarily hits the Snapdragon models like the PocoF1 (which is still not patched)

    • the Note9 also seems to be much more energy-efficient when using two SIMs at the same time, on the PocoF1 I have seen a very large increase in the idle power consumption over night when I switched from one single SIM to two of those

    • direct headphone audio is IMHO the best again on the Note9, and LDAC (against a Sony WH1000XM3) on Bluetooth defaults to "best effort" on all and don't seem to retain any change for that; all 3 are very sensitive if at the same time a WiFi connection on the 2.4GHz is active, with probably the PocoF1 and the S10e being the most affected.

    So this were my 2 cents, please ask if you have questions and I will try to answer at some point.

    Google shouldn't approve auto renewal of subscriptions without biometric authentication / password lock

    Posted: 30 Aug 2019 01:03 PM PDT

    Today at 9:28 PM i got a SMS from my bank stating my a/c was debited 1699 rs ( $24 ). I checked my bank website to check where was it credited to. It said bumble.

    I quickly went to check my email. There was nothing. No notification about auto renewal. I got bumble free trail ( 14 days ) and it said it will renew subscription after 14 days. But there was no confirmation to reauthorize the payment.

    Google always asks for my fingerprint before i purchase any app / book. But neither Google nor bumble prompt me before renewing my subscription because it's " auto renewal ".

    I contacted Google and requested a refund. And i for a email stating i should get it within few days. I know 1699 rs isn't much but i think users should be given a prompt before authorizing purchases including subscriptions. Some kid's games use this flaw aswell, your kid can basically buy " gems or coins or extra lives " as packages and you'll get charged without needing to authorize payment. Every month. Bumble already has class action lawsuits for this same reason.

    I'd like to thank Google for offering a refund. I prob got it because i asked for it immediately. But i think Google should make it mandatory for the user to authenticate subscriptions if it's setup in Google play settings to avoid accidental purchases.

    Thanks for coming to my TED talk.
