Common Problrms in OnePlus One

 

Problem: Yellow tinge on display
A number of OnePlus One owners have encountered a problem with a yellow tinge on the bottom portion of the screen. Some people have found that the whole screen seems to be tinted yellow. There could be two separate issues here. The tint may be a software issue that’s easily fixed. The problem affecting the bottom portion of the screen isn’t as clear cut. There have been suggestions that it’s caused by undried glue and rushing the phones out. However, the Oppo Find 7 and 7A have the same display and the same problems and Oppo suggested it may be due to a backlight that isn’t uniform and they’re testing and replacing afflicted handsets.

Workaround:

• If you’ve got the latest version of CM 11 (you can check via Settings > About phone > Cyanogenmod updates > Check for updates) then go to Settings > Display & lights > Screen color > Custom > Hue and try fiddling to get rid of the yellow.

Potential solutions:

• Some people are suggesting that the yellow portion at the bottom of the screen will go away in time, but you can speed this up by placing it under UV light. ThisYouTube video suggests putting the display in direct sunlight for an hour or two. If you decide to try it we’d recommend not doing it in a really hot environment like a car especially since windscreens tend to filter out UV. To be honest we’re skeptical about this fix, but it’s easy to give it a try and you’ve got nothing to lose.
• If it’s a build issue then you are going to have to return the phone and get a replacement. If it’s a genuine fault then OnePlus should eat the cost and fix or replace it, but there are reports they aren’t accepting returns for this issue (let us know in the comments if you’ve tried). You can return it without quibble if you’re within the first 14 days, but you are going to have to pay the shipping and handling costs.

Issue: Dead pixels
There’s always a chance you’re going to get a dead pixel or two on a new display and a few OnePlus One owners have reported exactly that. You can test for it and try a repair before you have to contact OnePlus.

Potential solutions:

• Try using a free app like Dead Pixel Detect and Fix and see if you can bring it back to life.
• You should be able to return your OnePlus One and get a replacement, but they might not do it if you only have one or two dead pixels. Different manufacturers have different policies on this and some require three or more before they’ll replace the device. We don’t know OnePlus’s stance.

Glitch: Unresponsive touchscreen and ghost touches
Quite a few people seem to have run into a touchscreen glitch with the OnePlus One where it won’t register touches or it does register touches that you haven’t made. There could be more than one issue at play here. If you want to test for the problem try using the free Yet Another MultiTouch Test app.

Workaround:

• Try holding down the Power button to turn the phone off and on again. A reboot will generally solve the problem at least temporarily. It may even be enough to just turn the screen off and on again.
• It could be a grounding issue. Does it only happen when the phone is sitting on an isolated surface? Try holding the phone or using the touchscreen while it is plugged in to charge and see if the issue is gone.

Potential fixes:

• Some people have found success by changing the theme that they use. It’s definitely worth a try.
• The issue has been acknowledged and OnePlus apparently worked with Synaptics to find a solution that involves a new firmware driver. It will be rolled into a CM 11 update which you should get OTA, but you can check here Settings > About phone > Cyanogenmod updates > Check for updates or go direct to Cyanogenmod for the latest build.

Problem: Random reboots
A lot of people have encountered random reboots with their OnePlus One where it will just turn itself off and on again for no apparent reason. There are a lot of potential reasons for this so try to look for a common pattern when it happens, is it related to a specific app, a new theme or ROM, or a certain combination of features or functionality being on?

Workarounds:

• Try turning off the NFC function if you have it on and see if that makes a difference.
• Some people have found that the problem is related to Wi-Fi and it only occurs when Wi-Fi is switched on and connected. Unfortunately living without Wi-Fi isn’t a realistic long term solution.

Potential fixes:

• Try changing the theme you are using.
• It’s possible an app is causing the issue. You could try uninstalling apps one by one and see if the reboots keep happening.
• Alternately you can try a factory reset and reinstall apps selectively. To factory reset make sure you backup everything first and then turn the phone off. Hold down thePower button and Volume down button until you feel it vibrate. Select wipe cache partition by pressing the Power button and then choose wipe data / factory reset.
• You could try rooting and flashing a new ROM. You’ll find a good guide at XDA developers forum.
• You can try contacting OnePlus and arranging a return and replacement.

Issue: Won’t charge or slow charging
Some OnePlus One owners have had problems with charging the phone. There are reports that it won’t charge at all and reports that it is charging, but extremely slowly.

Potential fixes:

• Make sure you are using the charger and cable that came with the OnePlus One and that your wall socket is working.
• Try a different cable and charger that definitely works to make sure that’s not your problem.
• If it won’t turn on then leave it plugged in for a couple of hours and then hold down the Powerbutton for a good 20 seconds and see if it comes back to life. OnePlus suggests that you try holding the Power button down for 20 seconds five times to power cycle the phone.
• Try plugging it into your PC and see if it’s recognized or if it charges.
• Try holding down Power and Volume down and see if it boots into recovery mode.
• If nothing works, you’re going to have to return it.

Glitch: Call volume low
Do you find the volume through the speaker or earpiece to be very low during calls? You’re not alone.

Potential fixes:

• A lot of people think an OTA (over-the-air) update has solved this issue. Make sure you’re up to date by going to Settings > About phone > Cyanogenmod updates > Check for updates or go direct to Cyanogenmod for the latest build.
• If you’re willing to tinker then try this edit suggestion at XDA Developers forum or the tool at the OnePlus forums. It seems to have done the trick for some people, but proceed at your own risk.
