Samsung Galaxy A40 is rated 3.9 out of 5 by 28.
Rated 3 out of 5 by from Good phone, shame about the battery life. Got this phone in April, first thing I noticed was how bad the battery life was. I have to charge the phone over night and then again in the afternoon otherwise by the evening it will run out of battery. I dont even watch movies on it. My old Samsung phone I only had to charge once every 24 hours! This is very inconvenient. Another issue I have with it is it keeps saying sim card error, no sim inserted! Have never had an issue like this with any other phone I've owned. Have now taped the sim in place and cleaned it, still no luck. Have even factory reset the phone and still it keeps saying error. Apart from that the phone is good/average, nice camera, small and easy to hold with one hand. I've got the blue one, it's such a lovely colour. Finger print scanner at the back works well. Decent phone for price. Cant really go wrong with a samsung phone, even with a few issues, think I might just have a dodgy one, lol.

Rated 3 out of 5 by from The size is great for pockets I bought this phone a week ago online after 6PM on a Saturday arrived next day Sunday 9am wow very impressed carphonewarehouse. Chose this phone because my trusty moto G4 after 3years the screen cracked. I would of liked another moto but they are just to big and was looking for a more compact budget phone. The A40 is a perfect size but miss the features of the moto like visual notifications, missed calls and text when picking up the phone now I have to press the on button to view. Also the quick shortcut activation for photo and torch were great on the moto. After a week the A40 runs well, smoothly and screen is clear even in bright sunlight. I love the compact size easy to use in the hand, does not feel like your carrying a small TV around. The phone is easy to use but can't comment about it longliviety as only had the phone a week. I'm not a heavy phone user and the battery only just last 24 hours so it could be a problem for those that play games or use it as sat navigation without keeping the charge topped up. In all I like the phone but perhaps heavy users need to keep battery life in mind.
