The HTC One M9 probably deserved to do better in the market than it eventually did. HTC themselves announced lackluster sales from what looks like a very capable device. The design is on point and the build quality is terrific. Nobody knows exactly why the sales didn’t work out, but I believe it had something to do with the camera. HTC definitely fell behind on the camera megapixel and then tried to sell it off as an ulta-pixel. Cameras a huge part of a reason why people choose a device and particularly the women who are shopping for a new device.

Another potential downside is the Sense UI HTC devices come with. I understand many people enjoy the Sense UI and I think there are many great aspects to the HTC Sense 6.0 UI too. However, it forces Google to take more time integrating new software updates which always has HTC toward the bottom of the flagship list when receiving new software updates. When you combine camera and software you have now taken away fair weather sales and hardware tech enthusiast sales.

What that being said, there is a clear way around not having OTA updates coming your way in a timely fashion: installing a custom ROM. Many of the custom ROMs that come out for your HTC One M9 smartphone will be coming out to update your firmware to newer versions of Android before the OTA’s arrive. That is the same for all devices — even the ones that get updates quicker than HTC like Motorola usually would after being a Google company in the past.

Files You Need

LeeDroid

Another household name in the custom ROM industry is LeeDroid ROMs. Hopefully the developers don’t read this, but I find their promoting to be incredibly generic: the most features, most stable and most optimized .They would have to be the three most common words whenever you have to read about a new ROM promotion. The LeeDroid ROM is currently in the nightly stages for the HTC One M9 so whether that is true or not is up to you to find out. If the features list is anything to go by, we’d say this ROM is definitely one of the more feature-rich ROMs out there for any device.

DarkSense

The DarkSense ROM isn’t as popular as some of the others. In fact, we’d say it’s probably one of the least popular custom ROMS out there for the HTC One M9 device. However, they have made an advanced power menu that is incredibly useful and should be enough to get many users. The power menu I’m referring to comes with the bootloader mode, recovery mode and safe mode options available. Furthermore, the same power menu also gives you reboot and hot reboot options.

Features: Best AROMA experience, Based on HTC One M9 1.32.401.15, Android 5.0.2, Sense 7.0, Advanced Power Menu, Extended Native Quick Settings, Long Press Back to Kill, Stripped debugging info from framework, Flashlight in Power Menu, Zoe Camera, Harman/Kardon Support and more.

SkyDragon

The SkyDragon custom ROM for the HTC One M9 smartphone is the ROM you want if you want outstanding battery life. It’s also incredibly fast and buttery smooth. We like to think that any Custom ROM that comes with a quality pictures means that is likely a great ROM. Of course, that’s not always true and you can get some great ROMs made by third-party developers who haven’t bothered to put any graphical detail into a logo at all. Regardless, the SkyDragon team have one of the coolest logos out of any custom ROM that will likely lure you in to at least giving it a try.
