Permanently repairs rubber keypad buttons by replacing the conductive material.
Your keypad fails when the conductive pad wears out and silicone oils seep from the keypad. This gooey paste blocks electrical conductivity and stops the switch from working. Membrane keypads block the oil from reaching the circuit board and offer a new conductor that cannot break down like rubber conductors do.

ǂ REPAIR SERVICE
MAXIMUM 2 PHONES (two) sent in at the same time
Repair for these problems (Important! remember to send a problem description with your items)
PLEASE do not send in phones with multiple serious problems. Some phones sent in are an obvious basket case. Dirty, worn with a broken antenna that has already been repaired once with epoxy, etc... If the phone has a broken antenna AND a bad keypad AND a blank display then you need a replacement phone, not repair. If you aren't sure, please send me a message with photos and describe the problems. CONTACT
At ButtonWorx.com I have no easy way of adjusting the order after you place it. I cannot add or remove services. I can't easily account for unrepairable phones or requests for a new battery, etc.. This service is intended for OK looking phones that have a hard to press keypad and one other simple problem. If the phone was crushes, left out in the rain for a week, covered in epoxy, chewed on by a 200lb dog... please do not send it in unless you are donating it for parts.
This is very confusing for everyone. Electronic circuits cannot check battery health. The best they can do it try and track battery usage. The battery voltage can hint that the battery is fully charged (if voltage is maxed) or low charge (with a low voltage) but some batteries act differently. SO fully charged VS dead is easier to read but most of the in between levels are guesswork by software trying to track battery level. Some batteries have built in circuitry to track battery health but most do not. Some devices have memory for the battery health but if the battery is removed the device doesn't know if the same battery is inserted or if it's a different one, so it needs to guess... or what usually happens is the device will assume the battery is low and needs charging.
If your device is frequently resetting for any reason and the battery level is being forgotten, the device will probably tell you to charge the battery even when it doesn't need it. This will create more heat than usual when charging and if done repeatedly it will degrade your battery much faster, shortening it's useful life.
