Smartphones these days are getting to the point where everything is fast and capable enough. While buying a more expensive smartphone brings improvement in speed and display quality, these things are getting to the point that the average user cannot tell the difference all that much.
The average used wont notice the difference between the Qualcomm S4 Pro on a Google Nexus 7 and the fast Qualcomm S600 on the HTC One. The HTC has the sharpest resolution of any phone with a 4.7-inch display with a staggering 1080 x 1920 resolution. In every day use,many users may not notice the difference between the HTC One and its Full HD display and the 4.7-inch HD display (768 x 1280) display of the Nexus 4.
So while we pony up more cash for the fastest phones and the sharpest displays, more and more, the phones other features are becoming more important. Personally, the one thing I appreciate most about newer phones is better and better cameras. I no longer buy a compact digital camera, as a secondary camera to a DSLR (or DSLT).
GSM Arena has an excellent tool to compare phone camera image quality and looking for a replacement for my current phone it is a useful tool for making a buy option. The tool can compare up to three phones at a time.
Using the tool I compared the average 8 MP shooter on the Nexus 4, with the improved 13 MP camera on the Samsung Galaxy S4 and the 4 MP Ultra Pixel camera on the HTC One.
Scaling the pictures down to match the test resolution of the HTC One as 3 MP, which is something you are likely to do when uploading images to the Internet or sending them by mail, the 4 MP camera on the HTC One looks disappointing, while 13 MP camera on the Galaxy S4 produced the best result.
The results are the same on the ISO 122333 Chart. The 13 MP camera on the Samsung Galaxy S4 seems to have the best low light capabilities, in addition to providing the sharpest images.
