I have the phone for a week, the battery lasts perfectly for 2 days with data usage for social media and music. The camera is very good with nice colors. It runs all the applications quickly. It's worth the money!
They call me, the phone rings without showing that they are calling me and of course without being able to answer and see who called me. It happens with 5% of incoming calls. I have had it for 40 days and I will order another mobile phone.
This mobile phone is the best I have ever bought! I highly recommend it. I have had it for 2.5 years now and it has not presented any problems. It's not an iPhone 15 pro max, but for the price of €120 that I bought it for... it's simply worth it.
I got it as a gift for my mother for easy use. She uses it for calls and occasionally uses Viber. After 1 year of use, the mobile simply doesn't work. It shuts down, can't answer incoming calls, so in short, it's useless now. I wouldn't recommend it anywhere!
I got it as a gift for my mom, she only used it to watch movies and listen to music, after 1.5 years of use it freezes incredibly and can't open basic applications or answer calls. For a little more money, I would suggest looking at something else.
I have had it for 2 years and I haven't encountered any problems. We're talking about a mobile phone that costs 100 euros. Well, okay, the camera is not great, but I don't really care about that aspect.
Well, for my own use:
Full Facebook, Instagram, etc.
YouTube for work reasons
Downloading movies
Using it as a full hotspot
And it's a beast.
Now, of course, these are personal preferences
Good phone but I would recommend a Samsung A generation with the same money, even though the design of the phone is a copy of the Samsung A02. I wasn't particularly satisfied, it's better to go straight to Samsung.
Do not take it after a while the screen creaks.
Take another one for the first phone is fine!! After 4 years, it can't function like when you bought it!! ..
I have this mobile for 1.5 years, and I have a total of about 4,000 photos and videos, and I still have 500mb left. As time passes, the camera gets worse, so when I got it, it took good photos and videos, but now everything is blurry and bad. If you want a mobile at a good price for less than a year, then this is the ideal one.
I bought the mobile phone a year ago and it works terribly, it freezes a lot and it doesn't support anything. It is a mobile phone that no one should buy because it's a waste of money
I bought this specific mobile phone in November 2021 after the majority of positive reviews, and after a year of use, I have to admit that the few negative comments that existed back then were absolutely right. I will mention my own points that bother me particularly, and I am a person with simple requirements, so I will not refer to photos, videos, RAM, ROM, etc., as these are things that I have already rated in this evaluation.
Initially, when I first started using the mobile phone, it responded perfectly and I was very happy with my choice. However, over time, as technology advances and applications become more demanding, the mobile phone started to slow down in the first semester.
Now, I encountered an application (IKEA) that I cannot download because this specific mobile phone is not a compatible device to run it.
I use Bluetooth a lot for my smartwatch, hands-free, music at home and in the car. One out of three times, I have to restart it in order to pair it with one of the devices I mentioned.
Many times, when I receive a call and I have it connected via Bluetooth to a device, the mobile phone takes so long to display the answer option on the screen that the call ends and I have to call them back afterwards.
I also use communication apps a lot, such as Viber, WhatsApp, etc. The mobile phone has reached a point where I have to enter the respective application myself and it mistakenly shows that a message has just been received, which in reality was sent earlier.
Finally, the battery drains quickly, requiring daily charging, and personally - because I sleep late + wake up early - I put it on airplane mode when charging it in order to make the charging more efficient.
Well, the mobile phone is worth the money, the only complaint I have is the rear speaker that loses sound and the charging is slow if you charge it during unnecessary hours. It is good for anyone interested in buying it. The battery takes about 2 hours to charge, but it is good. I have had it for 6 months and it is good for daily use. I can say that gaming is relatively good
The sound on calls is low. The other person can't hear you well on speakerphone. The touchscreen gets stuck when pressed and often needs to be pressed again. Slow charging. Not a good choice for me
Very good mobile for its price. After 6 months of use, it feels like it just came out of the factory. The only thing that concerns me is the fingerprint sensor. Other than that, it's an amazing mobile.
We are talking about a mobile phone that costs 100-130€, so based on that, it is worth it!!! You don't expect the speed of more expensive phones!! It is good for social use and you don't care if it breaks! Average photos, bad videos!! But as we said, for 100€ it's great
The xiaomi redmi6 that I had performed better even though it had 3gb RAM instead of 4gb and a processor of 1.8Mz instead of 2.3Mz. The positive thing is that it has more memory (64 instead of 32 that I had), definitely a better camera, but the negatives are the large screen (for my personal preferences). I would expect the battery to last longer as it is about +40% of the xiaomi (5000mah instead of 3700). Finally, my old one (VERY SATISFIED) I bought it 3 years ago for 110E, I hope this one will also serve me as well... Generally, based on my research, it is quite honest for the time (105E) and for someone to get something significantly better (e.g. more RAM, processor, and internal memory) they have to spend over 150E.
15 months of use and if you add two more applications, everything freezes! It takes a long time to execute the applications and there is a chance that it won't show who is calling you or you won't be able to answer!
Very good battery and camera resistant to heavy use but very slow now.
Personally, I want to share with you my personal opinion about this product. Nowadays, it is perfect in terms of its features. It takes very clear photos and has a beautiful screen without unnecessary words. I have had many mobile phones and properties in my hands, and this one is very good. The battery is perfect, but the only downside is the speaker. It's not that it doesn't work, it's just not the best. Personally, I paid 130€ and I am fully satisfied! I hope I helped with my review!
There isn't much I have to say. The camera is fantastic, very fast, and one of the best value-for-money phones on the market. Although it says the charger is only 10W, it goes from 20 to 100% in about 2 hours. Also, it lasts about 1.5 days with full use. In the specific photos, I am in the beautiful Nafplio, so it helps the situation a little...
It was purchased for an elderly person who was looking for a cheap mobile phone. It was bought for 120 euros with 4/64 storage.
The battery lasts for a full 2 days with mainly browsing data. The camera is very good with nice colors. It runs all applications quickly. It's worth the money!
Also, the mobile phone is compact and I have seen videos before buying it where it is used in extreme conditions, such as falls, and the phone doesn't get damaged.
The only (-) is the speaker, which is located on the back of the phone and has low volume. But again, with a good MP3 ringtone, you don't have a problem.
It is a very good mobile phone and for its price, I would say it is unreal. The only thing that ruins the rating is that the GPS is almost useless. It never finds satellites (in any place I have been) etc
The mobile was purchased on 7/01/2022 at a price of €135, for such a value-for-money mobile in relation to its features and capabilities. The 13mp camera is excellent, the operating system is not yet ready for heavy use as it has many bugs and it is understandable why it is still in the 2nd version (Realme UI 2.0). For gaming purposes, I would not recommend it because the graphics of the Helio G35 are not suitable. In my test (with light and heavy games like Subway Surfers, Roblox, free fire, PUBG, and need for speed), you notice the pixelation, and in terms of temperatures, it did not exceed 30°. The battery is perfect, lasting 1.5 days with continuous use on social media and phone calls. As for the screen, for its price, it is relatively good, but in very low brightness, you notice that the intensity starts to flicker (i.e., goes up and down at low levels). The speaker during calls was loud, the listener can understand and hear you clearly. The fingerprint sensor is very fast, as is the Face ID. In terms of network, it would be good to support 5G WI-FI. I also noticed that when Wi-Fi and location (GPS) are enabled at the same time, the Wi-Fi speeds are much slower. I confidently recommend it if you want something value-for-money for everyday use!
Update 9/5/2022
After 5 months of use, the mobile started to show manufacturing problems. The Wi-Fi is very slow when the location is enabled. Also, now when I download various applications/games, they don't open at all. I tried to delete them and download them again, restart the mobile, but they don't get fixed at all. My opinion about the mobile has changed, it is suitable for very basic use and nothing more.
The phone was purchased for my mother, 55+, my friend who is 33+ also has it, it is very good in everything, just the speaker should not be on the back because it reduces the volume when you receive calls. It needs a case to improve this a little.

The battery is now a joke, it only lasts one day on standby. Never again realme
I got it for a relative, it's a good simple phone, good camera, good resolution, and it plays games well. It's also good for social media. Yes, the sound is not good, but it's a good functional phone with a good battery. I recommend it for people who want the basics for a smartphone
The mobile phone not only rocks but it's perfect. I have almost all the social media apps and I spend all day on it, playing games without any lag and the photos are just top-notch. Background blur and focus where you want! And the battery is amazing, I open it in the morning and it lasts until the evening without charging, just buy it.
18/9/2022 The phone does the basics! Just in the morning when you open it, it freezes because it's overloaded! Of course, I used it heavily and for its price, it does its job! It might freeze for a bit in the morning because I receive multiple notifications at once. Final opinion, if you want it only for social media and some gaming, it's worth it and more, but after a year, its performance will decrease.
29/4/2023 Guys, everything is perfect, there is no lag at all, everything is perfect. I have used it heavily, it has fallen from high places and from work, and it doesn't even have a scratch. The battery's performance hasn't decreased even after 3 years, if you like it, buy it, it rocks.
