Samsung postavlja senzor otiska prsta sa strane na neke Galaxy telefone zato što fizičko Side dugme može istovremeno da bude i kontrola i lako prepoznatljivo mesto za dodir. To nije dokaz da je bočni senzor uvek brži ili pouzdaniji od čitača ispod ekrana: izbor zavisi od modela, načina držanja telefona i ličnih navika.

Zašto je Samsungov senzor otiska prsta sa strane?

Na telefonima sa bočnim čitačem, senzor je ugrađen u Side dugme, odnosno bočno dugme. Korisnik tako može da ga pronađe dodirom, bez traženja određene tačke na prednjoj strani ekrana. Samsung na nekim modelima nudi i čitač ispod ekrana, pa položaj zavisi od konkretnog Galaxy uređaja, a ne od jedinstvenog pravila za celu liniju.

Na primer, Samsungova američka stranica podrške navodi čitač na Side dugmetu za Galaxy Z Fold7 i Z Flip7, dok se kod Galaxy S modela i odabranih Galaxy A modela koristi čitač ispod ekrana. Spisak se menja, a dostupnost modela i specifikacije mogu da se razlikuju po tržištu; proverite stranicu podrške za tačan model i region. Samsungov vodič za registraciju i korišćenje otiska prsta navodi raspored za podržane modele.

Da li je bočni senzor bolji od senzora ispod ekrana?

Ne postoji univerzalni pobednik. Bočni čitač može biti zgodniji ako palac prirodno naleže na dugme dok držite telefon, a fizička ivica pruža taktilni orijentir. Ako vam je dugme nezgodno za dohvat ili često menjate ruku, položaj može biti manje praktičan. Čitač ispod ekrana ostavlja bočnu kontrolu slobodnom i uklapa se u prednju površinu telefona, ali zahteva da prst postavite na predviđeno mesto na ekranu.

Samsung je 2019. naveo da je njegovo potrošačko istraživanje ukazivalo na sklonost ka centralno postavljenom prednjem senzoru zbog dosega palca, kao i da ugrađivanje čitača ispod ekrana oslobađa više prostora za prikaz. To je tadašnje Samsungovo obrazloženje, ne novija nezavisna studija o tome koji položaj korisnici danas preferiraju. Samsungovo objašnjenje ultrazvučnog skenera iz 2019.

Šta vredi uporediti pri izboru telefona

  • Pronalaženje senzora: bočno dugme daje fizički orijentir; da li se poklapa s vašim hvatom zavisi od veličine telefona i ruke.
  • Otključavanje pri držanju ili podizanju: razmislite da li vam je prirodno da dodirnete bočno dugme ili da prst položite na ekran. Nema osnova da se iz samog položaja zaključi da je jedna opcija uvek brža.
  • Prednja površina: čitač ispod ekrana ne zauzima bočno dugme, a Samsung je očuvanje prostora za ekran naveo kao razlog za taj dizajn.
  • Zaštitno staklo ili folija: dodatna zaštita može da utiče na prepoznavanje kod nekih uređaja sa čitačem u ekranu. Samsung preporučuje zaštitu predviđenu za senzor tog uređaja, kada je primenljivo. Proverite Samsungove napomene za svoj model.
  • Slučajna očitavanja: na podržanim uređajima moguće je isključiti „Fingerprint always on“ ako želite da sprečite neželjena očitavanja. Dostupnost i naziv opcije zavise od modela i softvera.

Položaj senzora nije isto što i tehnologija senzora

Bočni ili prednji položaj govori gde je čitač; ne određuje sam po sebi kako senzor očitava otisak. Samsung opisuje ultrazvučni čitač ispod ekrana kao sistem koji šalje talase kroz ekran i pravi trodimenzionalnu mapu grebena i udubljenja otiska. Kompanija kaže da je pristup namenjen i suprotstavljanju pokušajima prevare pomoću dvodimenzionalnih kopija. To je Samsungov opis namere i tehnologije, a ne nezavisni dokaz da je određeni položaj ili tip čitača uvek bezbedniji. Samsung objašnjava ultrazvučno očitavanje.

Kako registrovati otisak i rešiti probleme s prepoznavanjem

Putanja i postupak mogu se razlikovati po modelu i verziji One UI-ja. Samsungov vodič za podržane uređaje navodi registraciju kroz podešavanja bezbednosti i zaključanog ekrana, a telefoni sa Androidom 16 i One UI 8 koriste postupak registracije prevlačenjem.

  2. Pratite uputstva na ekranu i postavite prst preko senzora. Samsungov vodič navodi da je moguće registrovati najviše četiri otiska.
  3. Ako telefon ne prepoznaje otisak, prekrijte senzor prstom u celosti i proverite da li su i прст и сензор чисти и суви. Код екрана са уграђеним читачем проверите и да ли заштитно стакло или фолија омета очитавање.

Samsung наводи да после поновног покретања телефона или више од 24 сата без употребе корисник мора да унесе PIN, лозинку или шаблон. То је безбедносни захтев, а не знак да је сензор покварен. За тачне називе менија и подешавања проверите актуелни водич за свој модел.

Kako odlučiti koji položaj vam više odgovara

Ako možete, isprobajte telefon u položaju u kojem ga najčešće koristite: dok ga podižete, držite jednom rukom i otključavate palcem. Obratite pažnju na to da li bočno dugme prirodno dolazi pod prst i da li vam smeta slučajan dodir. Kod senzora ispod ekrana proverite da li vam je lako da prst postavite na označeno mesto i da li zaštita koju koristite podržava pouzdano očitavanje.
