Expert Review


The Panasonic Eluga Ray 550 is a very decent low-end budget smartphone. It may not have a completely bezel-less body but the Full View display looks good. The overall performance is decent and the camera department is capable of good captures. However, we miss out on fast charging and the OS is also a bit outdated considering no future updates. If you want a decent offering from Panasonic in this segment, go for the Eluga Ray 550. In case you want to check out the competition, then look at the Honor 9 Lite, Redmi 6 and Asus ZenFone Max M1.


Panasonic Eluga Ray 550, a modern budget smartphone, was launched in India back in April 2018. It comes with a modern 18:9 display but the body is not completely bezel-less in nature. Apart from the looks of the Eluga Ray 550, the hardware is just about average and not extraordinary. However, it is good to see brands like Panasonic is entering the modern smartphone era to compete with other players. So let us take a look at the Panasonic Eluga Ray 550 review to find out if you should purchase this phone or not. Although, you must take a quick look at its specifications first.

The Panasonic Eluga Ray 550 runs on Android 7.0 Nougat OS and is powered by a MediaTek MT6737H quad-core processor and 3GB RAM. The phone boasts of a 5.7-inch HD+ display and packs in a 3250mAh battery under its hood. There is 32GB of internal memory onboard but you can also expand it further up to 128GB. There is a fingerprint sensor at the back. In the camera department, we get a 13 megapixel camera at the back along with a 8 megapixel camera on the front. The Eluga Ray 550 has 4G VoLTE connectivity along with Dual SIM support. Other options include 3G HSPA+, WiFi 802.11 b/g/n, Bluetooth 4.1, GPS and GLONASS. The Panasonic Eluga Ray 550 features a lot of sensors such as magnetometer, accelerometer, ambient light and proximity sensors.

Design & Display:

The Panasonic Ray 550 has a modern design and thus it looks very sleek for a low-end budget smartphone. It has a metal build and it surely feels solid in hands. Despite having a fairly large display, the phone feels quite compact and you can still use it with one hand easily. It may not be completely bezel-less but the full-screen display looks great. The phone is on the thicker side (8.5mm) but it does not weigh (152 grams) much. The edges are slightly rounded and it gives a very solid grip. The metal back panel has a matte finish but it is still a bit slippery. So we would advice you to use a protective case.

Starting with the front side first, there is a 5.7-inch display along with the selfie camera, LED notification, couple of sensors and earpiece on top. The mobile comes with on-screen buttons for navigation and hence there are no capacitive buttons. We get the Panasonic branding on the chin below the display. At the bottom, we have the microUSB port along with the primary microphone while the 3.5mm headphone jack is located at the top. The volume rocker and power/lock button are on the right while the left side houses the slot for SIM and microSD cards. Turning towards the back, we have the primary camera on the top middle followed by the LED flash and fingerprint sensor below it. The Panasonic and Eluga branding are seen below the fingerprint sensor. The loudspeaker holes are seen at the bottom. The back cover is non-removable but a 3250mAh battery (non-removable) sits underneath it. Overall, the Panasonic Eluga Ray 550 has a solid build and decent hardware.

The Panasonic Eluga Ray 550 features a 5.7-inch IPS display, which has a resolution of 1440 x 720 pixels (HD+). It is a modern display with good viewing angles. The 18:9 bezel-less display looks great for a budget smartphone. The colors are sharp and vivid. We get good brightness and contrast levels as well. The images, texts and videos look crisp but it would have looked better on a Full HD+ display as expected. The display has decent sunlight legibility as well and since it has an ambient light sensor, the brightness gets adjusted automatically according to the lighting conditions. We get a layer of 2.5D curved glass on top of the display to protect it from daily wear and tear and it does it successfully but you should not expect it to save the screen from a drop. Thus, always use your phone carefully and protect it with a proper case.

The touch response of the Eluga Ray 550 is very smooth because of the 2.5D curved glass and fluid UI. Overall, the Panasonic Eluga Ray 550 comes with a good display panel.


In terms of performance, the Panasonic Eluga Ray 550 is powered by a MediaTek MT6737H quad-core processor along with 3GB RAM. The CPU is a low-end chipset but it can handle most of the basic day-to-day tasks without any issues. Most of the popular apps and games load up fairly quickly but high-end apps and games might cause some lag. The 3GB RAM provides a good multitasking experience and you can easily perform some multitasking by running more than five or more apps simultaneously. There was no visible UI lags as well but occasionally there was some stuttering here and there. In terms of gaming, you can play all the normal 3D games without breaking a sweat but high-end games will lag a lot and will run in low or medium settings. The Eluga Ray 550 comes with 32GB of internal memory, out of which around 25GB of free space was available after first boot. You can increase it up to 128GB by adding a microSD card. The fingerprint sensor located at the back and it works very accurately and is quite fast as well.

Talking about connectivity, the Eluga Ray 550 from the house of Panasonic supports Dual SIM (nano) and is of course 4G VoLTE enabled. Both the slots are 4G enabled but simultaneously only one slot can be used for 4G while the other will work on 3G. The 3250mAh battery (non-removable) under the hood provides a battery life of up to one day with moderate usage but there is no fast charging support.

Overall, the Panasonic Eluga Ray 550 is a very decent performer.


The Panasonic Eluga Ray 550 comes with a generic 13 megapixel primary rear camera. It clicks decently good images in natural outdoor lighting and we get some amount of details. The color saturation is on the higher side but the photos quite look sharp. The colors are bright and vivid. Now coming to the low light environments, the pictures look a lot of noise and grain. The focusing mechanism speed is slow but accurate. HDR photos look good and is the best mode for clicking landscape images. Macro shots offer some depth of field effect as well. On the front, we get a 8 megapixel selfie camera and it clicks good selfies. You can also use beauty mode and other filters to make the selfies look better.

The camera app of the Ray 550 is very simple and easy to use. There are various shooting modes including a pro mode for mobile photography enthusiasts. However, we would suggest you to use the Auto mode as it works well in most lighting conditions. The rear camera can shoot Full HD videos but it is basic in terms of quality. Overall, the Panasonic Eluga Ray 550 comes with a pretty basic set of cameras.

Audio & Video:

The machine drilled loudspeaker holes of the Eluga Ray 550 are located at the bottom of the back side. There is no audio distortion even at the highest volume level. The speaker is quite loud and is good in terms of quality. Since the speaker is placed on the back side, audio gets blocked by palms while watching videos or playing games. The native music app has most of the necessary features and thus you do not have to download any third-party app. Although, you can download any music streaming app like Saavn to stream music online.

Now coming to the video watching experience on the Eluga Ray 550, you can play both HD and Full HD videos without facing any issues but it will struggle a bit with Ultra HD or 4K videos. There is no bundled earphone with the phone and hence you should purchase a good pair of earphones. Overall, the Panasonic Eluga Ray 550 offers a very decent audio and video watching experience.

Software & Ui:

Out of the box, the Panasonic Eluga Ray 550 runs on Android 7.0 Nougat OS. It is not the latest OS from Google and we do not expect any major update in the future as well. However, we would be happy to be proven wrong by Panasonic. Now talking about its features, it more or less feels like stock Android and has similar functionality. We can customize the UI a bit as there is a skin on top of vanilla Android. We found it to be mostly fluid and smooth in basic day-to-day activities but there were slight frame drops here and there. There is Arbo Hub and it helps in adapting to user specific needs, interests and also provides information to users w.r.t. services such as cricket, news, payments, cab booking and more on a single platform. The Ray 550 comes with some pre-installed apps (bloatware) but you can easily uninstall them and save up on some internal storage. In case you do not like the look of this interface, then you can download any third-party theme such as Pixel Launcher or Nova Launcher to get a different look and feel.

Overall, the Panasonic Eluga Ray 550 has a fluid interface but the base Android OS is a bit old.
