Xiaomi is quite a phenomenon in the smartphone world. The company made its name thanks to compelling smartphones with an appealing price. The Redmi Note and Mi series bring some of the most successful Xiaomi smartphones to date, and since 2018, the company has also been stealing the spotlight with its POCO sub-brand. Although premium Xiaomi smartphones are often stealing the headlines, we have to say that most of the company’s success comes from the mid-range and cost-effective flagship segment. The company launched a myriad of successful smartphones in the past few years, that conquered a legion of fans, however, the company had some problematic or… unreliable devices throughout its story.
So far, one of the issues that have plagued mid-range Xiaomi smartphones over the years has to do with the quality of the IPS panels. Some Xiaomi users certainly know the “tianma” provider. It has been a supplier of IPS LCD panels for Xiaomi that are known for their screen retention issue. There are also other issues that made some Xiaomi smartphones unreliable. Through this article, we’ll list some of the most problematic and unreliable Xiaomi smartphones.
Unreliable Xiaomi smartphones
Most of the unreliable Xiaomi smartphones released in the past few years have some characteristics in common, among them, we can list things such as:
- Being released too early and without the necessary tests
- The phone didn’t go through reliable tests
- Something went wrong during the shipping steps
- Unreliable tests left some small issues getting the green light
Unfortunately, some Xiaomi smartphones were considered “successful” despite the issues that are well known by users. These users had to deal with certain issues due to the fact that some of them were associated with the hardware. The “tianma” screen problem, for example, was impossible to fix the screen retention issue. As a workaround, users don’t keep their brightness high. When the issue is software related, the situation is less problematic, as Xiaomi can simply roll out a software patch to fix them. However, this isn’t the case with problematic devices.
Devices with IPS “Tianma” screen
We don’t hear the “Tianma” name often in Xiaomi news, but this name is certainly known by Redmi smartphone owners. Nowadays, there are fewer Xiaomi and Redmi devices with this screen, but it has affected a massive amount of Redmi smartphones in the past, especially those on the Redmi Note series. If you have a Tianma screen, then we can say that your device is 90% susceptible to screen retention or “ghost screen” issues. It resembles AMOLED’s burn-in screen issue, it’s an annoying issue. Just imagine having the battery, and Wi-Fi icon showing everywhere, even when your device is on full-screen and you’re watching a movie, for example. There are some ways to bypass this issue such as reducing your screen brightness and calibrating the colors. Unfortunately, the best ways are only available if you flash a custom ROM onto your device.
Xiaomi didn’t fix the ghost screen issue, it can’t, after all, it’s hardware related. Unfortunately, the company keeps using Tianma panels on low-end devices, but the situation has improved on higher devices such as those on the Redmi Note series. We can thank the “High-Refresh Rate” and “AMOLED” trend that forced Xiaomi to leave Tianma on some devices. Devices affected by the “screen retention” issue include:
- Redmi Note 8
- Redmi Note 7
