I predict that someone will now mention the potential for burn in on AMOLED displays. For the record, I've been working at a phone store since November and thus seen many a customer's old Galaxy phone. The only burn in I've seen have been on the display models, not people's years old phones.
It can occur for the unlucky people though, just as LCDs can suffer from backlight bleed and other issues. Every different display technology has the potential to go wrong.
Exactly.
I've had Galaxy phones since the S2, and the last time I saw burn in was after using the S2 for over a year, after that had S3, S4 and Note 4.
My S4 I've had since Global launch in early 2013, used it up until late 2014 as my main, it is used as a GPS , especially when holiday at a destination where I have hired a car with no SatNav, or as a hotspot, to this day the display has no burn-in.
My Note 4 I have had since late 2014 launch up to currently, no burn-in either.
Samsung have done a great job in fixing a lot of issues AMOLEDs had in their early days. From the Note 2 up, the issues of Daylight legibility, sharpness etc... Are a thing of the past. The burn-in issues seemed to disappear in the S3 days.
It is understandable with Display Units, but I will be impressed when they sort that out to, but it seems these are issues even a lot of different makes of TVs still have.
The day Apple start using AMOLED will be great, I do wish my iPads display was as good as my Note 4's, in terms of contrast of colours, sharpness and vividness.
The Display settings that Samsung has been able to implement in the Galaxys are what I really like, from having the most blown up colours (I use AMOLED Cinema, love the high saturation), to more neutral, and even toned down, and then also Adaptive, allowing the phone to adjust according to lighting in whatever area you in is great.
