An awesome student from our education program made this wiki. It is not managed by iFixit staff.

This wiki is to address common problems with the Tengda S5+ and list potential solutions.

Speakers Crackle ¶ 

Phone's speakers make a crackling sound when used.

Volume too high ¶ 

Listening to audio at higher volumes can cause the speakers to emit a crackling sound. Lower the volume on the device to fix this problem.

Water damage ¶ 

If your phone has recently been exposed to or dropped into water, this may have damaged the speakers. Water damage will require that the speakers be replaced. Use the Speakers Replacement Guide for assistance.

Defective speakers ¶ 

Sometimes the speakers make this noise without any apparent reason. If so, the speakers may be defective and need to be replaced. Use the Speakers Replacement Guide for assistance.

"No SIM Card" Error ¶ 

When I turn on my phone, I get a SIM Card Error.

Loose SIM Card ¶ 

This may be caused by the SIM Card being to loose in it's housing. This can be fixed by turning off the phone and resecuring the SIM card located under the back case and above the battery. Use the Battery Replacement Guide to gain access to the SIM card.

Dirty SIM Card ¶ 

A SIM Card error may be caused by a dirty SIM card. This can be fixed by turning off the phone and removing the SIM card located under the back case and above the battery. Use the Battery Replacement Guide to gain access to the SIM card. Wipe the connection points on the SIM Card with a dry microfiber cloth before placing in it back in the phone (do NOT use water).

Incorrect SIM Card ¶ 

SIM Card errors may also be caused by using the wrong type of SIM card for your phone. Check your phone's owner manual to find out what kind of SIM card your phone requires. You can also check the Tengda S5+ device page here.

Phone won't charge ¶ 

I plug my phone into the charger, but it doesn't charge.

The Charger is Incompatible ¶ 

The phone will not charge if the correct charger is not used. Check the phone's owners manual or the Tengda S5+ device page to see what kind of charger is needed.

The Charger is Damaged ¶ 

Sometimes the charger may be damaged. Try charging the phone with a different charger or replacing the broken one.

Home button is unresponsive ¶ 

When I press the Home Button, it doesn't work.

The button is dirty ¶ 

A dirty home button can cause it to be unresponsive. To solve this problem, follow the Home Button Replacement Guide to gain access to the home button and clean any dirt away.

Battery won't hold charge ¶ 

After I charge my phone, the battery dies quickly.

Old Battery ¶ 

The battery in your phone may be too old. Old batteries lose their ability to hold charge and will require a battery replacement. Follow the Battery Replacement Guide for assistance.

Damaged Battery ¶ 

If your phone has received any damage lately, this might have also damaged the battery. Damaged batteries will need to be replaced. Follow the Battery Replacement Guide for assistance.

Overcharged Battery ¶ 

Another cause of a quickly dying battery is overcharging. This occurs when you leave your phone charging overnight or for long periods of time. Next time you charge your phone, only leave it charging until your phone is fully charged.
