6 smartest smartphones of 10 years ago

Stereo speakers

It is not necessary to have speakers on the front like the HTC One series, but the integration of stereo speakers is necessary to enhance the sound experience on smartphones. As the phone gets bigger, the trend of phablet is growing, dual speakers are not too difficult equipment for manufacturers on high-end products.

Waterproof

Once considered a standard for future smartphones, the water-resistant smartphone race is only Sony. Last year, Galaxy S5 competed with the Xperia Z line in IP67 water resistance. However, with Galaxy S6, Samsung has omitted this feature that many users regret.

Multitasking, split screen

With powerful hardware and an open Android platform, manufacturers are able to bring exclusive features to their products. Samsung and LG developed Google's operating system in their own way, taking advantage of the big screen to run two or more applications at the same time. Processors are constantly being upgraded, in the future this feature is expected to be improved.

Physical mute button

All iPhone lives have a vibrating / bell lever in the top left corner. This button can be fully integrated into the software, but the physical keys provide users with control over the status of the smartphone or switch easily. Physical buttons provide a sense of security for users, especially during meetings or where noise is avoided.

Touch pen

The multi-touch screen is able to accurately identify the fingers but the stylus is still the necessary equipment on the big screen smartphones. Samsung is the leading manufacturer of this trend with the Galaxy Note series with integrated S-Pen. Some other companies also launched products to compete but no model has created the attraction like Galaxy Note.

Two-tone flash

Flash is an important component when taking photos in low light conditions. The integration of two LED bulbs in two hot-cold tones will make the photos look more natural. It can be said that Apple is the start-up company for this problem and now HTC, LG and many other manufacturers have launched smartphones with two-tone flash.

Biometric sensors

Currently smartphones of companies like Apple, Samsung, HTC and many Chinese companies have models with integrated fingerprint sensors. This technology is welcomed by users and promises to be the standard for high-end phones next year.
