The one on my Moto G Power 5G works just fine. It has a side mounted power button with the fingerprint reader built into it. It reads very quickly, and apparently very accurately, so much so that 99% of the time I’ve tried it you can just press the power button normally with the correct finger and this also unlocks the phone. The advantage I can see there is that it does not require a separate action to operate at all.
(I don’t keep my fingerprint reader activated, though, for security purposes. Down with fingerprint readers in general, at least if you live in the US where the police can compel you to supply your fingerprint to unlock your phone.)
The under-screen reader in my previous Moto Z4 never worked worth a damn.
Honestly I’m pretty impressed with the G Power 5G overall. It’s a “budget” phone so certain people will inevitably get unreasonably butthurt over the lack of “premium,” but is quite fast enough for everything I do, gets great battery life, has a headphone jack and memory card slot, a good screen that’s 120hz capable, and it’s only $200-250 depending on the color. I think its cameras are just fine. How so? Well, check out any of my post history over the last month or two – All of my photos lately have been taken with that phone.
