Samsung Galaxy A90 (5G) 128GB/6GB RAM SM-A908B (GSM Only, No CDMA) Factory Unlocked Android Smartphone - International Version (Black)

Great phone even in 2022. BATTERY 10/10 Battery lasts very long and doesn't get hot while gaming in normal room temperatures. Ran 720p YouTube videos at around 25% brightness for 2 hours and only lost 10% charge. Very good. The battery lasts a good amount of time while gaming too. I get around 6-7 hours of Brawl Stars with no heat issues at all (at normal room temperatures, the battery temperature was always below 35 degrees Celsius and rarely went above 30 on most days). Genshin Impact drains the battery faster. On Genshin Impact lowest settings, I get around 4-5 hours of battery life. Haven't tested battery life on highest, but the battery gets warm on highest which is expected on any phone without an external cooler. Great battery life overall. PERFORMANCE 8/10 Haven't had any lag issues at all on this phone with normal use such as web browsing, productivity and YouTube. Samsung DeX works with no lag or stutters and provides an excellent desktop experience when connected to an external display. Many apps can be opened simultaneously with no lag thanks to the 6/8GB RAM. Games run very smoothly even on high settings. The Snapdragon 855 is strong even in 2022 and can run demanding games well. Alien Isolation, a AAA PC/Console title that was ported to Android is extremely demanding, but the A90 runs this game very well (40-60fps) and I did not experience any stutters while playing. This game is more demanding than Genshin Impact, and yes, Genshin Impact runs without issues on this device, so it can run any game you throw at it. This phone is great for emulation too. PS2 emulation using AetherSX2 runs smoothly and 3DS emulation on Citra MMJ runs very well. At the time of writing this, this device didn't perform very well in Skyline (Nintendo Switch emulator) when playing 3D titles such as Super Mario Odyssey, but the emulator is still in development and even the latest flagships like the S22 can't run all 3D games on Skyline too well at the time of writing this. As the phone has a 60Hz display, the hardware doesn't get pushed very hard unlike if it had a high refresh rate such as 90hz or 120hz. As a result, most games are limited to 60fps, so games can be played on the Power Saving mode which can reduce heat, improve battery life and also prevent/reduce throttling as Power Saving itself throttles the hardware. If this mode is disabled, throttling can be observed when putting it through sustained loads such as 60fps Genshin Impact on high settings, but the throttling isn't bad. Using the CPU Throttling Test app, the phone throttled to 86% of the peak performance after 60 minutes of sustained CPU stress. CAMERAS 6/10 The cameras are a downside for this phone. The image quality of the cameras, both front and rear, is not up very good, but not terrible either. Night photos with the rear camera are not very clear and are quite noisy. If you want a great camera, this phone is not the best choice. SPEAKER AND MIC 4/10 The phone only has one speaker (other than the call speaker) located at the bottom right. The speaker is very quiet and is not very suitable for music or watching videos. I tolerate it because I almost never use the speaker, but if you want to use the speaker often, this is not a good choice. The microphone quality isn't great either. Voices are audible, but don't expect very good quality. It works and that is it. WIRELESS CONNECTIVITY 7/10 This phone does support 5G, but only 1 band of 5G, so I have been unable to use 5G at all where I live. 4G is very fast where I live, so this is not an issue for me, but if you want to use 5G, check what 5G bands your area uses before buying if you want to use 5G. Haven't had any issues with cellular connectivity other than that. It is fast and stable on 4G and I haven't had issues with calling either. Haven't had any issues with WiFi or Bluetooth either. WiFi is fast Using the mobile hotspot feature works well and is fast and low latency. I've used it to connect my PC to the Internet when my home Internet connection went down many times and used it for FPS games. Using the hotspot feature doesn't heat up the phone too much unlike some other phones I have tried. DISPLAY 7.5/10 This phone has a 6.7 inch (similar to the iPhone 14 Pro Max size) 60Hz 1080x2400 Super AMOLED display which is fluid and looks great for almost any use such as watching videos, web browsing and gaming. The screen is suitable for 1080p FHD video as it is 1080 pixels in height when held in landscape. If you want to watch higher resolution videos such as 2K 1440p or higher, consider an S series or a different phone with a higher resolution AMOLED display. For most people, this display should be more than enough. 60Hz is fine, but for gaming I would prefer 90Hz or higher, but this is an A series with a flagship chipset so it is reasonable for my use. There are many newer and more recent midrange phones with high refresh rate displays such as 90Hz and 120Hz if high refresh rate is important to you. STORAGE 7/10 This phone only comes with 128GB storage, which is sufficient if you don't take photos often and aren't a heavy user or if you use a cloud photo service such as Google Photos. The storage is fast as it is UFS 3.0. Haven't had any issues with the speed of the storage. I use emulators and some game ROMs can be large. I also run Linux through Termux and this uses a fair bit of my storage so for this kind of use, 128GB may not be enough for some. I am currently at 122GB out of 128GB with around 500 items in my photos, some games, emulator ROMs and Linux things. If you need more space, you can expand it with a microSDXC card (only on the 6GB RAM variant as stated on GSMArena). OVERALL I give this phone an 8/10. If you want a phone with great battery life and great performance but don't mind a subpar speaker and cameras, this phone is great. I really like this phone and for my use, I would take it over an S10. FAQ Does it support Samsung DeX? Yes it does. What is the latest One UI and Android version available for it? At the time of writing, One UI 4.1 and Android 12. Does it have a Snapdragon or Exynos SoC? It only comes with a Snapdragon 855. How much RAM does it come with? There is a 6GB variant and an 8GB variant. My review was based on my 6GB one. Where do you get one from in 2022/2023? This phone is a 2019 model, so if you want one you can look at preowned ones such as on Facebook Marketplace. As always, be careful when buying a preowned phone. Thanks for reading. Also, it'd be cool you give us One UI 5 for this phone. The A90 is special as it is has no successor. :)

You simply cannot buy a better phone for this price range, samsung has got mostly everything right with this phone. Great cameras, great screen and epic performance. Only feature I would have added is an IP rating. Other than that there is no complaints what so ever. Well done Samsung.
