Samsung Galaxy A10 is about to receive a newer, better sibling
The Samsung Galaxy A10 comes with only one rear camera – it's the only phone in the current A range to do so. The Galaxy A10s though adds a 2MP depth sensor to the A10's 13MP main camera, which should be useful for portrait shots in order to add appropriate background blur.
Another powerful upgrade is the battery capacity, which sits at 4,000mAh in the Galaxy A10s as opposed to 3,400mAh in the A10, so you're getting a lot more power, which should see you through many more hours.
One other new addition to the phone is a rear-mounted fingerprint sensor, which the basic A10 doesn't have. That should make turning on the handset that much easier.
